Introduction
A US-bound consumer product that contains, or is designed to use, a button cell or coin battery needs a product-level safety review before the sample, battery holder and packaging are approved. Reese’s Law and CPSC’s implementing rule address battery accessibility, warnings, instructions and certification. The correct certificate depends on whether the finished item is a general-use product or a children’s product; not every covered product needs a Children’s Product Certificate.
This Reese’s Law button cell battery importer checklist separates the final consumer-product configuration from lithium transport paperwork. Use it to brief the supplier and qualified product-safety reviewer. Do not rely on a battery datasheet, a generic test report or a “childproof” sales claim as proof for the finished model.
Screen the Final Product Configuration for Scope
The CPSC button cell and coin battery business guidance explains the federal requirements. Start by recording whether the consumer product contains a button cell or coin battery or is designed to use one. Include batteries supplied installed, loose in the package, separately packaged with the product, or expected to be inserted by the consumer.
The final design matters. Two products with the same electronics may differ because one uses a coin cell while another uses a cylindrical battery, or because one package includes the battery and another does not. Record battery chemistry, designation, dimensions, quantity, voltage, installation state, holder design, included tool and replacement instructions.
Then check exclusions and the precise regulatory definitions with a competent reviewer. Do not decide scope from the product name alone. A smart luggage scale tag, pet tracker light or temperature wristband may have different power designs by model. These links are sourcing routes, not representations about battery type, coverage or compliance.
Classify the Product Before Asking for a Certificate
Certification follows product classification. The CPSC Certificates of Compliance and eFiling update explains the current certificate framework and eFiling effective dates. Manufacturers and importers certify general-use products with a General Certificate of Conformity and children’s products with a Children’s Product Certificate, based on the applicable requirements and testing framework.
Do not write “CPC required” on every battery-product RFQ. First determine whether the item is a children’s product under CPSC rules, considering its intended use, marketing, design and other relevant factors. A product used by adults does not become a children’s product merely because a battery presents an ingestion hazard. Conversely, removing a cartoon from a package does not necessarily change a product designed primarily for children.
Record the classification decision, intended age or user, sales listing, packaging claims and reviewer. If the classification changes, reopen testing, certification, warnings and artwork. For a children’s product subject to 16 CFR Part 1263, confirm the applicable CPSC-accepted third-party testing and CPC position for the exact product and separately packaged battery configuration.
Treat the Battery Compartment as a Safety-Critical Assembly
The 16 CFR Part 1263 rule text sets requirements for consumer products containing button cell or coin batteries and incorporates or references detailed performance provisions. The factory drawing should identify the compartment cover, fasteners, threads, captive features, hinges, latches, housing material, tool requirement and assembly torque where relevant.
Review the product after normal assembly, not only the empty enclosure. Wires, gaskets, battery thickness, PCB location and decorative trim can change how the door seats. A screw that is long enough in a prototype may bottom out after a material change. A flexible housing may release a latch under stress.
Ask engineering to define critical dimensions and production controls. Examples include screw specification, thread engagement, cover fit, latch geometry and evidence that the battery remains inaccessible through the required use-and-abuse sequence. The applicable test plan must come from the responsible specialist and current rule, not an improvised tug test.
Battery Replacement and Service Scenarios
If consumers replace the battery, installation instructions should identify the correct battery and safe sequence without encouraging unsafe shortcuts. If replacement is not intended, do not assume the product is exempt; have the sealed design evaluated under the applicable requirements.
Consider what happens after a drop, battery replacement, overtightened screw, missing tool or worn compartment. The regulation’s performance criteria, rather than marketing terms such as “tamper resistant,” determine the review.
Control the Exact Battery and Holder Together
Create a paired specification for the battery and access assembly. Record battery manufacturer or approved source, designation, chemistry, dimensions, terminal arrangement, packaging, holder part, cover, fastener and assembly work instruction. Substitute cells can vary slightly in thickness or edge profile and may affect fit or accessibility.
Require written approval before changing the included battery, holder, screw, cover resin, enclosure tooling or assembly method. A lower-cost battery is not a procurement-only change. It can affect safety evidence, markings, function, transport records and customer instructions.
At incoming inspection, verify identity and defined dimensions using approved methods. Keep batteries segregated by lot and prevent loose cells from entering product cartons outside the approved pack-out. Handle storage and production controls according to the responsible battery and safety procedures.
Plan Warnings and Instructions Before Artwork Lock
The rule includes warning requirements for product packaging, accompanying literature and, where practicable, the product. Separately packaged button cell or coin batteries also have applicable packaging requirements. Have the responsible reviewer select the exact required wording, format, location and prominence for the final configuration.
Do not reproduce a warning from a competitor’s box. Maintain controlled artwork for product, retail package, battery package, instructions, ecommerce images and master carton where relevant. Ensure translation or additional-market content does not reduce the prominence or change the meaning of required US information.
Instructions should cover keeping batteries away from children, installation polarity where applicable, secure closure, replacement, disposal and action after suspected ingestion as required by the approved content. Avoid unsupported claims such as “completely childproof.”
A Pre-Production Buyer Checklist
- Identify the exact product, user, battery design and US sales configuration.
- Confirm scope and exclusions against current CPSC requirements.
- Classify the final product as general-use or children’s with competent advice.
- Lock the battery, holder, cover, fastener, housing and assembly specification.
- Agree the applicable product and packaging test plan.
- Approve warnings, instructions, online content and retail-pack artwork.
- Obtain the correct GCC or CPC based on classification and evidence.
- Prepare required CPSC certificate data for importer eFiling where applicable.
- Control battery, holder, tooling, firmware and packaging changes.
- Inspect the finished lot against the approved model and documents.
Keep an issues list for any gap between prototype and production. “Factory will improve the screw later” is not an approval. Require the corrected sample and evidence before mass production.

Testing Must Match the Product and Configuration
A test request should name the finished product, model, battery, holder, enclosure, firmware where relevant, package configuration and intended category. Confirm the current applicable standard or rule provisions with the laboratory and responsible reviewer. Record how samples were selected and whether they came from production tooling and normal assembly.
Read the final report beyond its conclusion. Compare applicant, manufacturer, factory, product description, photos, battery type, test methods and sample condition with the planned shipment. If a report covers a different enclosure screw or an earlier molded part, document whether supplementary review is needed.
Testing a battery component alone does not demonstrate finished-product battery accessibility. Packaging warning review does not demonstrate compartment performance. Keep mechanical, labeling, general product and certification evidence connected but distinct.
GCC Versus CPC: Keep the Record Accurate
For a general-use product subject to the rule, the manufacturer or importer uses a GCC based on a reasonable testing program as required. For a children’s product, a CPC is based on testing by a CPSC-accepted third-party laboratory for the applicable children’s product safety rules. The responsible party should confirm all requirements that belong on the certificate, not only Part 1263.
The certificate should identify the product, cited rules, certifying party, record custodian, manufacture information, testing information and laboratory details as applicable. It must correspond to the shipped model and production basis. Never relabel a generic laboratory report as the certificate.
If one program contains adult and children’s variants, do not combine their classification and certificate status for convenience. Maintain a SKU-level matrix and prevent the wrong document from being attached to the shipment or retailer submission.
Add CPSC eFiling to the Import-Entry Workflow
Since July 8, 2026 (2026-07-08), importers of finished consumer products that are already subject to a CPSC certification requirement must electronically submit certificate data at entry through the U.S. Customs and Border Protection Partner Government Agency (PGA) Message Set. CPSC states that the effective date for products entered from a Foreign Trade Zone is January 8, 2027 (2027-01-08).
eFiling changes how certificate data reaches CPSC at import; it does not change which products require certification. First determine whether the finished product requires a GCC or CPC under the applicable rules, then prepare the corresponding data for entry. A product outside CPSC certification requirements does not become certifiable merely because the eFiling system exists.
Coordinate the importer, customs broker and certifying party before the shipment departs. Reconcile the product identifier, cited rules, certifier, manufacturing and testing records, laboratory information where applicable, and entry data with the final SKU. The factory can supply accurate model and production facts, but the importer should control who files, which certificate record is referenced and how a correction is handled if the entry data does not match the shipment.
Factory Testing and Shipment Inspection
During production, control fastener installation, compartment closure and visible damage. The engineering plan may include defined torque checks, first-piece verification or destructive sampling. Operators need clear limits and calibrated equipment where measurements are relied upon.
At shipment inspection, sample finished goods across cartons and verify model, battery type, compartment assembly, included tool, warnings, instructions, retail-pack artwork and certificate reference against the approved file. Perform only the defined tests with the proper method. Record any units opened or damaged and how they are replaced.
Inspection cannot certify the lot or recreate a full laboratory program. Its role is to discover whether production appears consistent with the assessed configuration. If a screw is missing, the battery differs or artwork is obsolete, place affected goods on hold and investigate scope before loading.
Change Control for Reorders
Reconfirm the bill of materials and product category for every reorder. Common risk changes include a new battery brand, alternate holder, revised mold, shorter screw, different housing resin, new battery inclusion strategy, artwork refresh, age-positioning change or bundle with a second product.
The change request should show old and new photographs or drawings, affected lots, technical rationale, report and certificate impact, artwork impact and proposed validation. Segregate old and new inventory. If a running change is unavoidable, create distinct lot records and do not mix evidence.
Product applications evolve. A general-use light sold later as part of a child-directed activity set may require a new classification review even if the battery compartment is unchanged. Marketing and bundle decisions belong in change control.
Keep Product Safety Separate From Transport Compliance
Coin and button batteries can also raise transport questions, especially when lithium chemistry is involved. Those requirements concern shipment classification, test summaries, packing and carrier processes; Reese’s Law addresses consumer-product ingestion and access hazards. One evidence set does not replace the other.
Use the lithium battery import-document guide for transport-document planning, then keep the product-safety certificate and Part 1263 evidence in the product file. Freight forwarder acceptance does not prove consumer-product compliance, and a GCC or CPC does not automatically satisfy carrier documentation.
Frequently Asked Questions
Does Reese’s Law apply when the battery is not included?
The rule covers consumer products that contain or are designed to use button cell or coin batteries, subject to its definitions and exclusions. Review the final configuration.
Does every in-scope product need a CPC?
No. General-use products use a GCC; children’s products use a CPC. Classify the finished product before requesting the certificate.
Does CPSC eFiling make additional products subject to certification?
No. eFiling changes the electronic submission of certificate data for imported products already subject to CPSC certification requirements; it does not expand which products require a GCC or CPC.
Is a secure-looking screw enough?
No. The final compartment assembly must be evaluated against the applicable performance requirements using the correct test plan.
Can a battery supplier’s report cover the finished product?
No. Battery data may support the file, but it does not demonstrate access resistance, final warnings or certification for the consumer product.
What changes should reopen the review?
Changes to battery, holder, screw, cover, housing material, mold, assembly, age positioning, instructions, packaging or bundle configuration can be relevant.
Can shipment inspection replace third-party testing?
No. Inspection checks production against approved references; it does not replace applicable testing or certification.
Build a Battery and Packaging SKU Matrix
One base product can appear in several US configurations: battery installed, battery packed separately with the product, battery not supplied, multipack, replacement-battery pack or bundle with another item. Give each sellable configuration a clear SKU and list its battery count, holder, included tool, retail package, warnings, instructions, intended user, test evidence and certificate status.
Do not assume the no-battery version automatically uses the same artwork or rule analysis. A product designed to use a button cell can remain in scope, and customer information must match what is actually supplied. Separately packaged batteries can raise their own packaging requirements. Ask the responsible reviewer to approve the matrix.
Warehouse and factory staff should pack from the released matrix. During inspection, select each configuration and reconcile the contents and markings. This is particularly important when the same plain product body is used for several channel bundles.
Evaluate Installation Preparation With the Final Pack
Have a person unfamiliar with the prototype open the production-representative package and follow the approved battery instructions. Observe whether the correct tool is available, the compartment closes fully, the fastener remains with the cover where required, polarity is clear and loose batteries can be misplaced during setup. Do not coach the participant through unclear steps; record them.
Route observations to engineering and the product-safety reviewer. A confusing instruction may need revision, but wording cannot compensate for a compartment that fails the applicable performance requirements. Conversely, a mechanically compliant design still needs accurate warnings and safe-use information.
Repeat the exercise after changes to packaging, battery brand, holder, screw or instructions. Preserve the sample revision and photos without showing readable proprietary artwork where confidentiality applies.
Manage Retailer and Marketplace Evidence Requests
Retailers and marketplaces may request test reports, certificates, product images, age information or battery details in their own format. Create a submission index that points to the authoritative product file rather than making new claims for each portal. Check that model names and business identities are consistent.
Platform acceptance does not replace CPSC obligations, and a rejected upload does not necessarily mean the product failed a safety test. Assign the issue to the correct owner: data mismatch, missing certificate field, outdated report, unclear classification or actual product gap.
Keep submission dates, case references and versions. If the product changes, update both the underlying evidence and channel records before the changed lot is offered.

Conclusion
A reliable Reese’s Law sourcing process starts with the finished product, not the loose battery. Classify the item, engineer the access assembly, approve warnings, match testing to the exact configuration and issue the correct GCC or CPC. Then protect those decisions through production and reorder change control.
