The Antitrust Division spent the spring taking apart the meatpackers and spent July writing to grocers. The letters it sent are the most interesting document produced in American retail this year, and that has less to do with who received them than with what they ask for. Eight companies got one: Kroger, Publix, Walmart, Albertsons, Aldi, Ahold Delhaize USA, Costco and Amazon. Associate Attorney General Stanley E. Woodward Jr. signed identical letters dated July 14, addressed separately to each, concerning what the department called recent increases in the retail price for beef.¹ The division made the expansion public in a post on its X account at the start of September, framing beef prices as a critical concern to Americans and a priority for the department.²

Before going any further, the caveat that most of the coverage has skipped. None of the eight has been charged with anything, and none has been found to have violated an antitrust law. A demand for records is a question, not a finding, and the distinction is going to get lost in a hurry over the next few months.

What the department actually asked for

Read the request list and you stop thinking about beef. The letters seek records on retail beef sales and prices, wholesale purchases, costs and margins, pricing and purchasing strategies, and each company’s own internal analyses of wholesale and retail beef price trends, all of it covering 2020 through 2026. Investigators also asked that company personnel brief them on four areas, including how beef pricing strategies and margins changed over those six years, how costs moved across the same period, and how each retailer structures its wholesale arrangements for buying beef from the packers.³ Strip away the subject matter and what has been requested is a category P&L, six years deep, from eight companies, delivered in comparable form to the same set of lawyers.

I have sat in the meetings where documents like that get produced, and the thing worth understanding is that none of them were written for this audience. The pricing strategy deck, the margin bridge, the competitive shop file, the vendor funding schedule, the one-line note explaining why a cost increase went through at a hundred and ten percent instead of a hundred, all of it was written by a merchant for another merchant in merchant shorthand, on the reasonable assumption that everybody reading it would understand the trade. Somebody else is reading it now, and that somebody is reading for intent. Sarbanes Oxley laws mean that all of these retailers have a perfectly preserved record of all correspondence covering this time period, and now all of it will be in the hands of regulators.

How this started, and why it did not stop at the plant

The chain of events is short and entirely public. In November 2025, President Trump accused meatpacking companies of driving up beef prices through collusion, price fixing and price manipulation, and asked the Justice Department to investigate. On December 6 he signed Executive Order 14364, which stood up Food Supply Chain Security Task Forces inside both DOJ and the FTC and aimed them at anticompetitive behavior across the food supply chain, naming meat processing alongside seed, fertilizer and equipment as sectors with similar vulnerabilities.⁴

In May the Antitrust Division opened a criminal investigation into the Big Four packers, JBS, Cargill, Tyson Foods and National Beef, which the department says control more than 85 percent of U.S. beef processing. By late summer it had reviewed more than three million documents and was interviewing industry participants, and Attorney General Todd Blanche had publicly pointed whistleblowers toward the reward program, offering 15 to 30 percent of any criminal penalty above a million dollars.⁵

So the department worked the concentrated middle of the chain for a full quarter, with subpoena power and three million documents in hand, and then moved downstream. There are two ways to read that sequence. Either the packing case is strong and retail is being pulled in to complete the picture, or the packing case did not find what it expected and the money had to be somewhere else. I lean toward the second reading, and the public data is the reason why.

The number that sent them to the shelf

USDA’s Economic Research Service publishes meat price spreads every month, splitting the retail beef dollar into three pieces: what the rancher gets, what the packer captures between the farm gate and the wholesale carcass, and what accrues between the wholesale carcass and the meat case. For August 2026, Choice beef carried a retail value of $10.23 a pound, the farm-to-wholesale spread was 39 cents, and the wholesale-to-retail spread was $4.61.⁶

Those proportions have held all year. The packer piece has run between six and fifty-five cents a pound every month since February, while the downstream piece has not dropped below $4.18 across the same stretch.⁶ Roughly ninety-two percent of the total spread between the ranch and the register now sits below the plant. For an antitrust lawyer trying to work out where the consumer’s dollar went, that is not a subtle signal, and it is the most plausible explanation for why eight grocers got mail in July.

The case for the defense, and it is a real one

Here is where honest analysis has to part company with the press release, because that $4.61 is not retailer profit. It covers the entire cost of everything that happens to a carcass after the packer sells it: fabrication into subprimals and case-ready cuts, cold chain freight, grinding, tray packing, film and labels, store labor at the meat counter, shrink on a product with a five-day shelf life, and markdown on whatever does not move by day five. Beef is the most labor-intensive and most perishable department in the building, and it has always carried the widest spread in the store.

The rancher’s share of that dollar has also gone up rather than down, which is awkward for the theory. ERS puts the farmer’s share of the retail beef dollar at 51.1 percent in August, and it ran as high as 55.6 percent in May.⁶ The comparable figure in May 2022 was 41 percent.⁷ Producers are capturing ten points more of the consumer dollar than they were four years ago, and that is not the pattern anybody would expect if retail buyer power were squeezing the chain.

The packers, meanwhile, are bleeding. On September 3 Tyson Foods cut its fiscal 2026 outlook for the second time in a month and guided its beef segment to an adjusted operating loss of $625 million to $775 million, citing margin compression amid volatile cattle prices and one of the most severe cattle shortages in U.S. history.⁸ The company is closing its Joslin, Illinois plant and its Eagle Mountain, Utah case-ready facility and shopping the Pasco, Washington plant. Cartels do not generally restructure around three facilities and book three quarters of a billion dollars in segment losses.

Retail gross margins are moving the wrong way for the prosecution as well. Kroger reported second quarter gross margin of 22.4 percent of sales on September 11 against 22.5 percent a year earlier, lowered its identical sales guidance for the year, and told analysts it will resist supplier price increases that are not justified by costs.⁹ A consolidated margin can certainly conceal a category margin, and finding that out is exactly what the letters are for, but the number that is currently public is falling rather than rising.

Most of the price story is explained by supply without anybody breaking a law. The January 1 cattle inventory came in at 86.2 million head, the smallest herd since 1951, with beef cows at 27.6 million, the lowest since 1961.¹⁰ Ground beef averaged $6.92 a pound in August, a record.¹¹ Beef and veal CPI is already decelerating hard, running from 16.4 percent year over year last December to 9.4 percent in July and 5.9 percent in August.⁶ That is the cattle cycle doing what the cattle cycle does, and cattle producers still want the retail books opened anyway. R-CALF USA, which called for precisely this back in May, said it was encouraged by the expansion and urged enforcement wherever anticompetitive conduct is found, pointing to the widening gap between cattle prices and beef prices.¹²

Publix is the one I would watch

Seven of the eight are national operators and one is not, which is what makes Publix the most interesting name on the list. Antitrust in grocery gets measured locally, because nobody shops nationally and the relevant market for a pound of ground chuck is the set of stores a household can reasonably drive to. On that measure Publix carries a concentration in its home markets that none of the other seven approach in theirs. Chain Store Guide put its share of the Miami metro at roughly 47 percent in 2023, against 15 percent for Walmart and 8 percent for Costco.¹³ That data is a few years old and grocery share numbers are never clean, but the shape of it is right, and shape is the first thing an investigator looks at.

There is a second reason to watch Publix, which is that the company already publishes a version of what the department just asked eight retailers to produce. The stock does not trade and the business is employee-owned, but Publix is an SEC registrant and files a 10-K like everybody else. Almost nobody in retail bothers to read it, and what is in it cuts against the theory. Gross profit as a percentage of sales was 25.4 percent in 2025, 25.6 percent in 2024 and 26.3 percent in 2023.¹⁴ Walk the filings back and the same line reads 26.8 percent in 2022, 27.4 percent in 2021 and 27.9 percent in 2020.¹⁵ That is 250 basis points of gross margin surrendered across almost exactly the window the Antitrust Division defined in its letters.

Publix attributes the recent decline to pharmacy mix and a Medicare reimbursement change rather than anything happening at the meat counter, and its 2023 filing attributed part of that year’s compression to product cost inflation the company chose not to pass on to customers.¹⁵ Setting the figure alongside Kroger’s 22.4 percent takes some care, since Kroger sells fuel and Publix does not, and fuel drags a consolidated gross margin down by several points. The two numbers are not the same measurement. What is comparable between them is direction, and both are heading the same way.

The harder look will come below the gross line. Publix net earnings landed at 7.5 percent of sales in 2025, or 6.7 percent once unrealized gains on the company’s equity portfolio come out.¹⁴ For a supermarket operator that is an unusually profitable business and has been for decades, and it is a business with no outside shareholders and no quarterly earnings call where an analyst gets to ask about the meat department. An investigator reading those facts sees a regionally dominant grocer with peer-leading profitability and no external pressure on its pricing. A merchant reading the same facts sees a company running excellent stores in a state with punishing real estate and labor costs, handing margin back five years running. Both readings fit the public record, and only the documents settle it.

Why this reaches past the meat case

If you run a category that has nothing to do with protein, the reason to pay attention is the method rather than the subject. Executive Order 14364 did not create a beef task force. It created a food supply chain task force at two agencies, with seed, fertilizer and equipment written into the text alongside meat processing.⁴ The department has now demonstrated the full play: open at the concentrated manufacturing tier, run it criminally, then send civil information demands to the retailers who touch the consumer and ask them to explain six years of category margin against six years of category cost. That template travels to eggs, dairy, baby formula, pet food and anything else with a concentrated manufacturing base and a shelf price that made the news.

It also collides with how modern retail actually earns its money. A grocery category P&L in 2026 is not cost plus markup. It is cost, less vendor funding, less scan-down allowances, less slotting, plus retail media attributable to the category, plus private label mix, net of loyalty-funded price investment. Kroger has just told the street it is funding shelf price reductions nearly one for one out of sourcing savings.⁹ Explaining a structure like that to somebody whose mental model is cost plus margin is genuinely hard work, and for these eight companies it is going to get done under subpoena rather than in a conference room.

The decision window

Preservation obligations attached the day the letters arrived, and the letters instructed the companies to preserve relevant documents, so that door has already closed for the eight. For everybody else it is open now and stays open until a letter lands on your own mat.

If you buy a concentrated category, pull your cost-to-shelf bridge for 2020 through 2026 this quarter and make sure somebody who is not a merchant can follow it end to end. If you cannot explain a pass-through decision from the documents alone, fix the documentation before a stranger reads it cold. If you sell into one of these retailers, your wholesale arrangements are now discoverable at eight of your largest customers, and category management agreements, promotional funding terms and exclusivity language will all get read in that light. And if you make the product, look hard at what happened to Tyson, which is carrying the criminal exposure and the losses at the same time. Concentration is a liability on both sides of the ledger in this cycle.

My read is that the retail piece of this ends in a report and a set of recommendations rather than a criminal case, and I would put that at better than two to one. The spread data says the money is downstream, but it does not say the money is illegal, and a farm share that has climbed ten points in four years is going to be hard for the department to argue around. The precedent set by the request survives the outcome either way, and that is the part worth planning for.

The investigation will run for years, but the document production will not. The companies that come out of this well are going to be the ones whose category economics were already written down in language an outsider could follow.

Keep thinking a few moves ahead.

September 2026

Executive Summary

LR44 and 357 button batteries are inexpensive, widely available and embedded in thousands of consumer products. They are used in small electronics, lights, toys, calculators, novelty products, watches, medical and personal devices, decorative products and countless other low-cost consumer goods.

That ubiquity is precisely what makes the category important for retailers.

The federal regulatory framework governing button-cell and coin batteries has now been in place long enough that the issue has moved beyond a new-rule implementation question. The requirements are active. Products manufactured or imported under the applicable dates must comply, and the U.S. Consumer Product Safety Commission has demonstrated that it is willing to take action against products using LR44 batteries specifically.¹

At the same time, the compliance environment surrounding imported consumer products has changed materially. Beginning July 8, 2026, importers of regulated consumer products became subject to mandatory electronic filing of Certificate of Compliance information with U.S. Customs and Border Protection through the CPSC eFiling program.² That development matters because it gives CPSC substantially more structured information about regulated products entering the United States and connects product-level compliance documentation more directly to the import process. If you are a CEO and you haven’t heard your team implementing this months ago (and your products use the affected batteries) you’re about to run into a compliance wall.

Marketplace operators are responding as well. Walmart has told Marketplace sellers that they are responsible for complying with applicable CPSC requirements and for ensuring that an appropriate importer is responsible for electronically filing required certificates. Walmart has also stated that it will not serve as the importer for Marketplace sellers.³

The result is a more connected compliance chain.

A retailer can no longer look at a button-battery product solely as a merchandising decision. The battery itself, the finished product, the battery compartment, the product warnings, the packaging, the manufacturer’s testing, the certificate of conformity, the importer of record and the marketplace listing can all become parts of the same compliance question.

For retailers carrying products that contain or are designed to use LR44, 357 or similar button batteries, this creates a practical need for SKU-level review.

The most important point is simple:

LR44/357 should now be treated as a product-compliance trigger during sourcing and assortment review, rather than as an ordinary component specification.

This report explains why.

What This Report Covers

This report examines five issues that are converging around LR44/357-type products:

First, the federal requirements. What Reese’s Law and the implementing CPSC regulations actually require of batteries and products that contain or use them.

Second, the enforcement signal. Why recent CPSC actions involving products containing LR44 batteries provide a particularly useful indicator of where enforcement risk is developing.

Third, the marketplace environment. How marketplace operators are incorporating CPSC compliance into seller requirements and product controls.

Fourth, the import process. Why the July 2026 CPSC eFiling requirement changes the practical compliance burden for imported products.

Fifth, the retail response. What merchants, category managers, sourcing teams and marketplace sellers should be doing now to identify and address exposure at the SKU level.

The purpose is not simply to summarize the law. The more important question for a retail executive is what the law means for the product pipeline.

1. WHY LR44 / 357 IS NOW A RETAIL ISSUE

The LR44 is a small alkaline button battery commonly sold under several related designations. The 357 designation is commonly associated with a silver-oxide version of a similar physical size. Product specifications and chemistry can differ, so retailers should not assume that the terms are interchangeable for every purpose.

The important regulatory question, however, is not whether a supplier calls a battery an LR44, AG13, 357 or another commercial designation.

The federal framework focuses on the physical characteristics of the battery and whether it falls within the statutory and regulatory definition of a covered button cell or coin battery. CPSC defines a button cell or coin battery as a single-cell battery with a diameter greater than its height, along with any other battery the Commission determines poses an ingestion hazard.⁴

That distinction matters.

A retailer conducting a compliance review should therefore search supplier documentation, product specifications and listings for the battery’s actual model designation and physical characteristics rather than relying solely on a keyword such as “LR44.”

LR44 batteries are particularly relevant because they appear in a large number of inexpensive products. They are small enough to be incorporated into products that may have little apparent connection to the battery market.

That creates an unusual retail problem.

The product being sold may be a toy, light, ornament, electronic accessory or novelty item. The compliance issue may nevertheless originate with the battery compartment and the accessibility of the battery.

CPSC enforcement illustrates the point.

In 2025, CPSC warned consumers about children’s light-up ballet skirts sold online that contained three LR44 alkaline button batteries. The battery compartment allowed the batteries to be accessed by children, and the products lacked required warnings. CPSC stated that the products violated the mandatory federal requirements governing consumer products containing button-cell or coin batteries.⁵

This is important because the enforcement action was not directed at a battery manufacturer selling a package of LR44 batteries.

It involved a finished consumer product.

That distinction should change how retailers think about the category.

2. THE REGULATORY FRAMEWORK

The federal framework originated with Reese’s Law, enacted in 2022 following the death of Reese Hamsmith, an 18-month-old child who ingested a button battery.

The law directed CPSC to establish requirements for button-cell and coin batteries and consumer products containing or designed to use them.

CPSC subsequently incorporated ANSI/UL 4200A into its mandatory safety standard. The resulting requirements are codified in 16 CFR Part 1263.⁶

There are two related but distinct regulatory issues.

The first concerns consumer products that contain or are designed to use covered button-cell or coin batteries.

The second concerns the packaging and labeling of the batteries themselves when sold as standalone products.

Retailers need to keep these two obligations separate because they operate differently.

Consumer products containing button batteries

For covered consumer products, the federal standard addresses battery accessibility, product construction, testing and warnings.

Among other requirements, the battery compartment generally must be secured in a manner intended to prevent access by children. The standard also incorporates use-and-abuse testing designed to evaluate whether the battery can become accessible during foreseeable use or misuse.

Warnings are also required.

The requirements apply differently depending upon whether the finished product is a general-use product or a children’s product.

For general-use products subject to the rule, the manufacturer or importer must provide the required certification of conformity.

For children’s products, the compliance burden is higher because children’s products subject to federal safety requirements generally require third-party testing by a CPSC-accepted laboratory and a Children’s Product Certificate.⁷

That distinction can materially affect sourcing economics.

A product that appears to be a simple $5 or $10 consumer item may carry a substantially different compliance burden if it is marketed, designed or classified as a children’s product.

Retailers should therefore avoid assuming that the battery requirement can be evaluated independently of the product’s intended audience.

3. STANDALONE LR44 / 357 BATTERIES HAVE THEIR OWN REQUIREMENTS

A retailer selling packages of LR44 or 357 batteries is dealing with a different compliance question from a retailer selling a flashlight that happens to contain an LR44 battery.

Reese’s Law also established special packaging requirements for covered button-cell and coin batteries.

CPSC’s current guidance states that covered button-cell and coin batteries manufactured or imported after February 12, 2023 must be packaged in accordance with the applicable child-resistant packaging requirements. Additional battery-package labeling requirements apply to products manufactured or imported after September 21, 2024.⁸

The packaging requirement is significant because the battery itself can create an ingestion hazard even when it is not installed in a consumer product.

Retailers therefore need to distinguish among at least three situations:

1. A standalone package of LR44/357 batteries.

2. A consumer product containing an LR44/357 battery.

3. A consumer product designed to use an LR44/357 battery, even when the battery is not supplied with the product.

The compliance analysis can differ among those scenarios.

This is one reason a simple product search for “contains battery” is inadequate for a retail compliance program.

The question should be whether the product contains or is designed to use a covered battery.

4. THE LR44 / 357 ENFORCEMENT SIGNAL

The clearest reason for retailers to pay attention to LR44/357 specifically is that CPSC enforcement has already reached the category.

In November 2025, CPSC announced the recall of Great Lakes Select battery packs that included a 24-pack of LR44/357 Super Alkaline batteries. The affected item was sold nationally from September 2024 through August 2025. CPSC stated that the battery packaging did not meet the required child-resistant packaging and warning requirements.⁹

The recall is notable for several reasons.

First, the product was inexpensive. The LR44/357 package sold for approximately $1.10 to $1.50.

Second, the product was a conventional standalone battery package rather than an unusual electronic device.

Third, the product had been sold through multiple retail outlets.

Fourth, the enforcement action demonstrates that CPSC’s attention is not limited to the most recognizable lithium coin batteries such as CR2032.

The LR44/357 category is clearly within the enforcement landscape.

The broader enforcement picture reinforces that conclusion.

CPSC has also taken action involving other button-cell products, including products where batteries were accessible to children or where required warnings were absent.

The regulatory risk therefore extends beyond the battery aisle.

A product can create exposure because of the battery it contains, the way that battery is installed, the way the battery compartment is constructed or the way the product is labeled and marketed.

5. THE MARKETPLACE HAS BECOME PART OF THE COMPLIANCE SYSTEM

For traditional brick-and-mortar retail, a product compliance issue historically moved through a relatively familiar chain:

manufacturer, importer, distributor, retailer and consumer.

Marketplace commerce adds another layer.

The marketplace may control the product listing, seller account, fulfillment process, documentation requirements and enforcement mechanism.

CPSC has already warned about button-cell products sold through online marketplaces. In one 2025 enforcement action involving children’s light-up products containing LR44 batteries, the products were sold online and CPSC issued a Notice of Violation to the seller.¹⁰

This creates a practical problem for marketplace sellers.

The marketplace does not necessarily need to wait for a federal recall before acting against a product.

A marketplace can impose its own documentation requirements, request testing records, restrict a listing, suspend a seller or require corrective action based on its interpretation of the applicable product-safety requirements.

That means regulatory compliance and marketplace compliance are increasingly intertwined.

6. WALMART’S NEW CPSC eFILING REQUIREMENT IS A SIGNIFICANT DEVELOPMENT

Walmart has now explicitly incorporated the new CPSC eFiling environment into its Marketplace requirements.

Walmart announced in August 2026 that importers of products subject to mandatory CPSC safety rules must electronically submit Certificates of Compliance through the CPSC eFiling process. Walmart stated that the requirement became effective July 8, 2026, with Foreign Trade Zone requirements beginning January 8, 2027.¹¹

Walmart also places responsibility on the Marketplace seller to ensure that the appropriate importer is responsible for the filing.

For a seller using imported inventory, this creates an important operational question:

Who is actually responsible for the compliance certificate associated with the product entering the United States?

That question should be answered before the product is sourced, not after a shipment is held or a listing is suspended.

For sellers using overseas suppliers, the importer relationship needs to be understood at the SKU level.

The retailer should know:

• Who manufactured the product.

• Who manufactured the battery, where relevant.

• Who imported the finished product.

• Who issued or maintains the applicable certificate.

• What testing supports the certification.

• Which SKU, model number or product identifier the certificate covers.

• And whether the product sold online is actually the same configuration represented by the compliance documentation.

That last point is particularly important.

A certificate is only useful if it actually describes the product being sold.

7. CPSC eFILING CHANGES THE IMPORT COMPLIANCE ENVIRONMENT

The July 8, 2026 implementation of mandatory CPSC eFiling is one of the most consequential changes in the practical compliance environment.

CPSC now requires importers of regulated consumer products subject to certification requirements to electronically file certificate information as part of the import process.¹²

The program is designed to give CPSC certificate information before regulated products enter U.S. commerce.

This changes the role of compliance documentation.

Historically, a retailer could think of a certificate as something that needed to exist in a file somewhere in case an agency, retailer or marketplace requested it.

That remains important, but the import environment now makes the information more operational.

The certificate becomes part of the data associated with the import transaction.

CPSC’s eFiling guidance states that a certificate must affirm that the product was tested to all applicable CPSC requirements and complies with the listed regulations. Certificates must identify applicable rules, standards and regulations, the most recent testing date and the testing laboratories used. Beginning July 8, 2026, applicable testing exclusions must also be identified.¹³

That creates a new level of discipline around product records.

A supplier saying that a product is “CPSC compliant” is not enough.

The retailer needs to know what regulation the supplier is relying upon, what testing supports the claim and which finished product the documentation actually covers.

8. eFILING IS NOT SIMPLY A NEW FORM

There is an important distinction between CPSC eFiling and what many people might casually describe as “product registration.”

The new system does create a structured electronic record of certificate information, and CPSC operates a Product Registry as part of the eFiling program.

But eFiling does not create a universal government registration requirement for every consumer product.

The underlying compliance obligation already exists.

The new requirement changes how certificate information is transmitted for regulated imported products.

That distinction matters because a retailer could otherwise misunderstand the requirement as a one-time registration process.

It is better understood as part of the import compliance workflow.

The certificate still needs to be accurate.

The testing still needs to support the certification.

The product still needs to comply.

The importer still has responsibility.

The eFiling system simply gives CPSC a more direct and structured way to receive and use the compliance information.

9. THE SKU-LEVEL COMPLIANCE PROBLEM

This is where the issue becomes particularly important for retail executives.

A company may have thousands of active SKUs and no obvious indication in its merchandising system that a particular product contains a button battery.

The battery may be buried in the bill of materials.

The supplier may describe it only as “AG13,” “LR44,” “A76,” “357,” or another designation.

The product title may never mention a battery.

The packaging may show a generic battery icon.

The product may be classified internally as a toy, novelty, personal accessory, lighting product or electronic device.

The result is a visibility problem.

A retailer cannot effectively manage a regulatory requirement if it does not know which SKUs trigger the requirement.

For this reason, the first step in a serious review should be creating a battery-product inventory.

At minimum, the inventory should identify:

• SKU or item number

• Product name

• Supplier

• Country of manufacture

• Importer of record

• Battery type

• Battery model or designation

• Number of batteries

• Whether batteries are included

• Whether the product is designed to use batteries

• Battery compartment design

• Target consumer or age grading

• Applicable certification

• Testing documentation

• Packaging documentation

• Warning documentation

• Marketplace status

• Current certificate holder

This is a relatively simple exercise compared with the disruption that can occur after a product has been listed, imported and distributed.

10. WHAT RETAILERS SHOULD LOOK FOR

A practical review should begin with products most likely to create exposure.

The first group is products that contain LR44, 357, AG13, A76 or physically similar button batteries.

The second group is children’s products.

The third group is products sold with loose batteries in the package.

The fourth group is products where the battery compartment can be opened without a tool or without the required level of protection.

The fifth group is imported products for which the supplier cannot quickly produce credible testing and certification documentation.

The sixth group is marketplace products sourced from multiple suppliers under the same or similar listing.

That last category deserves particular attention.

A retailer can have a compliant product configuration and then unintentionally introduce a different supplier’s version under the same listing.

The product may look identical in a photograph while using a different battery compartment, different battery supplier, different packaging or different warning language.

From a retail systems perspective, this creates a traceability problem.

Compliance should follow the actual product configuration, not simply the marketing image.

11. WHAT GOOD SUPPLIER DOCUMENTATION SHOULD LOOK LIKE

Retailers should be skeptical of vague compliance statements.

A supplier statement saying “FDA approved,” “CE certified,” “CPSC approved” or “meets U.S. standards” does not, by itself, establish compliance with the specific requirements applicable to a button-battery product. Compatible is no longer the standard, as import requirements and marketplace compliance require specific, certified laboratory test results at the per product level.

The documentation package should be specific.

For a general-use finished product, the retailer should be able to identify the applicable CPSC requirement and the corresponding General Certificate of Conformity.

Where testing is required, the retailer should be able to identify the testing laboratory and the test report supporting the certification.

For children’s products, the retailer should expect the applicable Children’s Product Certificate and supporting third-party testing.

For standalone button-cell batteries, the retailer should separately evaluate the packaging and labeling requirements.

The retailer should also retain the version of the product and packaging that was actually tested.

That last point is frequently overlooked.

A laboratory report for one packaging configuration does not automatically establish compliance for a different configuration.

A supplier changing the battery compartment, packaging, warning panel or battery supplier can create a new compliance question even when the product’s marketing description has not changed.

12. THE IMPORTER OF RECORD DESERVES SPECIAL ATTENTION

The eFiling environment makes the importer relationship more important.

Retail organizations should be able to answer a straightforward question for every imported regulated product:

Who is responsible for the CPSC certificate associated with this import?

If the answer is unclear, the compliance process is incomplete.

This is particularly important for marketplace sellers that source products from overseas suppliers.

• A supplier may manufacture the product.

• A freight forwarder may move the shipment.

• A customs broker may facilitate entry.

• A marketplace may fulfill the order.

But those parties do not automatically assume the same legal responsibilities.

Walmart’s current Marketplace guidance makes the point directly by requiring sellers to identify an appropriate importer responsible for eFiling and stating that Walmart will not serve as the importer for Marketplace sellers.¹⁴

That means the seller needs to understand its own supply chain rather than assuming that the marketplace is absorbing the regulatory obligation.

13. THE TIMELINE MATTERS

The federal requirements have been phased in over several years.

The following dates provide the practical compliance timeline.

February 12, 2023

Child-resistant packaging requirements began applying to covered button-cell and coin batteries manufactured or imported after this date.¹⁵

October 23, 2023

Federal performance and labeling requirements under 16 CFR Part 1263 began applying to covered general-use consumer products containing or designed to use button-cell or coin batteries manufactured or imported on or after this date.¹⁶

December 20, 2023

The corresponding requirements began applying to covered children’s products.¹⁷

September 21, 2024

Additional labeling requirements for standalone button-cell and coin-battery packaging became applicable.¹⁸

July 8, 2026

Mandatory CPSC eFiling became effective for most regulated imported consumer products subject to certification requirements.¹⁹

January 8, 2027

The eFiling requirements will extend to applicable products entering from Foreign Trade Zones.²⁰

The significance of this timeline is that the regulatory environment is now mature.

Retailers should not treat button-cell compliance as an upcoming requirement.

For the products already covered by the applicable effective dates, it is an existing requirement.

14. A NEW DEVELOPMENT: UL 4200A-2026

There is another development worth watching.

CPSC announced in September 2026 that UL had revised the voluntary standard incorporated into the federal button-cell rule from UL 4200A-2023 to UL 4200A-2026. CPSC is currently seeking comment on whether the revised standard improves safety.²¹

The comment deadline is September 17, 2026 (next week, as of our date of publication.)

This does not mean that every retailer suddenly has a new testing requirement today.

The regulatory process still has to run its course.

However, retailers with significant exposure to button-cell products should watch the development because the federal rule incorporates the UL standard by reference.

A change in the incorporated standard can eventually affect the testing and design expectations applied to covered products.

For sourcing teams, this is another reason to avoid treating compliance as a static document that can be filed away indefinitely.

Product safety standards can evolve.

15. WHAT THIS MEANS FOR MARKETPLACES

The practical implication for marketplace sellers is straightforward.

The combination of federal regulation, CPSC eFiling and marketplace enforcement creates several independent points at which a product can encounter friction.

A product can be questioned by CPSC.

It can encounter an import problem.

It can be subject to a documentation request.

It can be removed by a marketplace.

It can be placed on hold while compliance information is reviewed.

Or it can remain listed until an incident, complaint or regulatory action brings the product to attention.

The fact that a product has been selling successfully does not establish that it is compliant.

That may be the most important operational lesson in this entire category.

Historical sales are not a compliance certificate.

A product can sell thousands of units before anyone examines its battery compartment or asks for its supporting documentation.

Retailers should therefore resist using sales history as a proxy for regulatory acceptance.

16. THE RETAILER’S PRACTICAL RESPONSE

The appropriate response does not require pulling every product containing an LR44 battery from the market.

It requires creating visibility.

A practical program can begin with a targeted SKU audit.

Step One: Identify the products

Search product databases, supplier catalogs, bills of materials, packaging files and marketplace listings for:

• LR44

• 357

• AG13

• A76

• button battery

• coin battery

• button cell

• coin cell

and related battery specifications.

Do not rely on one terminology.

Step Two: Determine whether the product is covered

Confirm whether the product contains or is designed to use a covered button-cell or coin battery.

Determine whether it is a general-use product or a children’s product.

Step Three: Review the physical design

Examine the battery compartment.

Determine how the battery is retained.

Determine how the compartment is opened.

Confirm that the configuration matches the tested product.

Step Four: Review warnings

Confirm that required warnings appear where applicable on the product, packaging and instructions.

Step Five: Review certification

Obtain the applicable GCC or CPC and supporting test documentation.

Make sure the documents correspond to the exact product configuration.

Step Six: Review the battery itself

If the battery is supplied separately, review the battery packaging and labeling requirements independently.

Step Seven: Review the importer

Identify the importer responsible for the applicable CPSC certification and eFiling obligation.

Step Eight: Review marketplace requirements

Confirm that the marketplace’s product-safety requirements have also been satisfied.

Step Nine: Preserve the evidence

Keep the testing, certification, packaging artwork, photographs, supplier records and product specifications together.

The objective should be a defensible SKU file.

17. WHAT A DEFENSIBLE SKU FILE LOOKS LIKE

For higher-risk products, the ideal file should allow a compliance manager to answer the following question quickly:

“Show me why this exact product is legal to sell in the United States.”

The answer should not require an email chain with an overseas supplier.

It should not depend upon a generic PDF downloaded from a manufacturer’s website.

It should not depend upon a supplier saying that another retailer sells the same item.

The file should contain the actual evidence.

That includes the product identification, supplier information, battery specification, product photographs, packaging photographs, applicable certificate, supporting test reports, applicable warnings and the identity of the responsible importer.

For marketplace products, the file should also connect the compliance documentation to the listing or SKU being sold.

This is increasingly important because retail organizations are becoming more dependent upon data-driven compliance systems.

The future of product compliance is likely to be increasingly SKU-specific and increasingly digital.

18. THE BROADER RETAIL IMPLICATION

LR44/357 is useful as a case study because the battery itself is inexpensive and familiar.

The larger issue is the compliance infrastructure developing around products that enter the United States through global supply chains.

CPSC eFiling creates a more structured connection between the product, its certificate and its import transaction.

Marketplaces increasingly demand documentation before allowing products to remain active.

Retailers are becoming more responsible for understanding what their suppliers are actually selling.

And regulators have demonstrated that enforcement can reach products that appear commercially insignificant.

That combination changes the economics of compliance.

For a high-volume retailer, a $1 product can generate a disproportionately large compliance problem if it creates a listing suspension, import hold, recall, customer-safety issue or marketplace account restriction.

The cost of the product is therefore a poor measure of the cost of noncompliance.

This is particularly relevant to private-label and marketplace businesses, where hundreds or thousands of inexpensive products may be sourced from different manufacturers.

The lower the product’s price and the greater the SKU count, the easier it becomes for compliance gaps to hide inside the assortment.

19. RETAIL REASONING ASSESSMENT

Retail Reasoning believes the most important development in the LR44/357 category is not a single new rule.

It is the convergence of several existing requirements into a much more visible compliance system.

Reese’s Law established the underlying safety requirements.

CPSC created the implementing regulations.

Enforcement has demonstrated that the rules apply to ordinary consumer products and specifically to products containing LR44 batteries.

Mandatory eFiling has now connected regulated product certification more directly to the import process.

Marketplaces are incorporating those requirements into seller compliance.

And CPSC is evaluating a revised version of the technical standard incorporated into the federal rule.

Taken together, these developments point toward a retail environment in which product compliance will increasingly be evaluated at the individual SKU level.

The companies best positioned to operate in that environment will be those that can answer three questions quickly:

What exactly are we selling?

What regulation applies to it?

Where is the evidence that it complies?

That sounds simple.

In a large retail organization, it is not.

The underlying challenge is data integrity.

A retailer can have a certificate and still have the wrong product.

It can have a compliant product and still have the wrong packaging.

It can have compliant packaging and still have an outdated certificate.

It can have all of those things and still have uncertainty about who is responsible for the import filing.

The compliance system therefore has to connect the product, the documentation and the supply chain.

That is the real lesson from the LR44/357 category.

20. WHAT RETAIL EXECUTIVES SHOULD DO NOW

For retailers and marketplace operators with meaningful exposure to button-cell products, Retail Reasoning recommends five immediate actions.

1. Build a button-cell SKU list.

Identify every product that contains or is designed to use LR44, 357, AG13, A76 or another covered button-cell or coin battery.

2. Prioritize children’s products.

Children’s products generally carry a more demanding testing and certification regime and should receive immediate attention.

3. Verify documentation against the actual product.

Do not accept generic supplier statements. Match the certificate and test documentation to the product configuration being sold.

4. Establish importer accountability.

Know which entity is responsible for the applicable CPSC certification and eFiling obligations for imported products.

5. Create a recurring compliance review.

A product should be re-evaluated when its battery, battery compartment, packaging, supplier, manufacturer, importer or intended use changes.

These five actions will identify the majority of the practical exposure without requiring a retailer to launch a full enterprise-wide product compliance overhaul on day one.

21. THE BOTTOM LINE

LR44 and 357 batteries are small products with a surprisingly large compliance footprint.

The federal rules governing button-cell and coin batteries are already in effect.

CPSC has already taken enforcement action involving products containing LR44 batteries.

Standalone battery packaging is subject to its own requirements.

General-use and children’s products can carry different certification and testing obligations.

Mandatory CPSC eFiling has now added an import-level compliance requirement.

Marketplace operators are increasingly incorporating those requirements into their own seller controls.

And the technical standard underlying the federal rule is currently being reviewed for a 2026 revision.

For retailers, the appropriate response is not to treat every LR44/357 product as a regulatory emergency.

The appropriate response is to know where those products exist in the assortment, understand which requirements apply, verify the documentation and establish who owns the compliance responsibility.

The cost of doing that review is modest.

The cost of discovering the problem after an import, marketplace suspension, regulatory action or recall can be considerably higher.

For that reason, Retail Reasoning considers LR44/357-type products a useful early-warning category for a much broader change taking place across retail:

Product compliance is becoming a data problem as much as a legal or product-safety problem.

The retailers that understand that shift early will have an advantage over those that continue to treat compliance documentation as paperwork kept somewhere in a supplier’s inbox.

Methodology

This report was prepared as regulatory intelligence for retail executives and marketplace operators. The analysis focuses on primary regulatory sources, CPSC enforcement materials and marketplace compliance requirements available as of September 2026.

The report distinguishes between federal legal requirements, CPSC guidance, enforcement activity and marketplace policies. Where a development remains under regulatory consideration, such as the UL 4200A-2026 revision, it is identified as such rather than treated as an effective new requirement.

Retail Reasoning recommends that companies consult qualified legal and product-safety professionals when making product-specific compliance determinations.
