Button-Cell Test Reports: Qualify a Reese’s Law Request
Route a button-cell compliance request by product scope, battery access, test standard, certificate owner, packaging, warnings, production lot, and deadline.
Signals to watch
- A marketplace blocks a listing and requests a button-cell report without identifying the product model, test standard or certificate type
- An importer has a PDF from a supplier but cannot connect the sample, report, production lot and current finished product
- Packaging and warning images exist while no owner can show whether the battery-compartment accessibility requirements were tested
A “Reese’s Law report” request cannot be quoted from a marketplace screenshot alone. Identify the finished product and model, battery type, compartment design, age grading, claimed exception, applicable performance and warning requirements, test sample and production lot, certificate owner, packaging evidence and the listing or shipment decision date.
Reese’s Law is a US law addressing button cell and coin battery ingestion hazards. The Consumer Product Safety Commission (CPSC) implemented performance and labeling requirements through a federal rule codified at 16 CFR Part 1263. The rule concerns consumer products containing or designed to use button cells or coin batteries; it is not the same as transport testing of a battery cell.
The request is for a record chain, not one PDF
A consumer-product testing laboratory sales lead may watch authorised importer, marketplace-seller and product-compliance Telegram groups. If a listing review closes tomorrow, seeing “need Reese’s Law report” today can preserve the test window. The phrase still leaves four different workstreams hidden inside it:
- performance testing of the finished product and battery compartment;
- preparation or correction of a product certificate;
- warning-label or packaging review;
- recovery and matching of an existing supplier report to the actual model and production lot.
This illustrative composite is not a real seller, product or testing result:
“US listing asks for coin battery report. Factory sent an old PDF.”
“Model number on report is close, not exact. Cartons already printed.”
The thread does not show battery access, age grading, the report’s standard, sample identity, exception status, certificate, packaging warnings or shipment date. “Close” model numbers are not enough to assume that the tested sample and listed product share the same enclosure, fastener, battery compartment or warning artwork.
Which object must be tested?
The finished consumer product is the first object to identify. Capture the marketed model, variants, enclosure, battery compartment, fastener or tool needed for access, supplied battery and intended user. A battery supplier’s cell report does not automatically cover the product that contains the battery.
The CPSC Button Cell and Coin Battery Business Guidance describes the federal requirements and their scope. The September 2023 final rule established the performance and labeling standard. A laboratory should check the current official text and the actual product, not infer scope from the battery diameter or marketplace category alone.
Some products or battery compartments may fall within stated exceptions or different provisions. An exception claim needs the exact product design and source provision. It should remain an unknown in the intake record until a qualified reviewer confirms it.
Is UN 38.3 the requested evidence?
No. UN 38.3 transport testing concerns lithium cells and batteries offered for transport. Reese’s Law product evidence concerns consumer-product battery accessibility, security and warnings under the applicable US consumer-product rule. One battery may have transport evidence while the finished product still lacks the required performance record.
The distinction is commercially important. A seller who sends only a UN 38.3 summary may need product testing. A seller who has a valid finished-product test but cannot connect it to the listed model may need document recovery. The UN 38.3 test-summary request explains the transport chain; use it only for that separate question.
Which certificate belongs with the report?
Testing and certification are connected but not identical. The responsible manufacturer or importer must determine the applicable certificate route. A children’s product subject to a children’s product safety rule generally uses a Children’s Product Certificate (CPC) supported by testing from a CPSC-accepted third-party laboratory. A non-children’s product subject to an applicable consumer product safety rule generally uses a General Certificate of Conformity (GCC) based on the required testing or reasonable testing program.
The laboratory report describes the sample, method and result. The certificate identifies the product, rules, certifier and supporting testing information. A marketplace may request both, but a marketplace request does not change the statutory identity of the responsible certifier.
For teams already working on certificate fields, the CPSC eFiling certificate-data handoff explains how product, rule, test and importer records connect. That article does not establish whether a button-cell sample passed the Part 1263 requirements.
What must match before an old report can be reused?
Use a seven-link comparison:
| Link | Evidence to compare | Common break |
|---|---|---|
| Product | marketed name, model and variant | report covers a sibling model |
| Design | enclosure and battery-compartment drawings or photos | fastener or access method changed |
| Battery | type, size and supplied configuration | listing bundles a different cell |
| Sample | sample identifier and receipt date | sample cannot be tied to production |
| Method | cited standard, clauses and deviations | report tests only one requirement |
| Result | observations, measurements and disposition | summary page hides a failed condition |
| Production | factory, lot, change record and current artwork | later design or packaging change is undocumented |
A mismatch does not always require a full retest. It requires an engineering and compliance decision supported by the actual change. The lab should quote only after the responsible reviewer decides whether the old evidence remains applicable, needs a gap test or must be replaced.
Do packaging and warning images close the request?
Not by themselves. Packaging and product warnings are visible evidence for labeling requirements. They do not prove that the battery compartment resisted access under the applicable performance tests. Conversely, a performance report does not show that current packaging carries the required warning language and symbol placement.
Ask for product and package artwork in the form used for the US market, revision numbers and print dates. If cartons are already printed, record that operational deadline without promising that a sticker, over-label or reprint is legally sufficient. The correct remediation depends on the exact defect and qualified review.
How should an early Telegram fragment be handled?
TOP Prospect can help a testing laboratory find and group relevant fragments in Telegram groups the user deliberately connects and is authorised to access. It can retain the original message, source and time for human review. Its current production matching-target interface saves configuration but does not yet automatically create new candidates.
The product cannot inspect the finished product, authenticate the factory report, choose a certificate, enter CPSC systems, contact a seller or declare compliance. A human laboratory and compliance team must verify the product, test basis and record chain. The public Telegram business-signal workflow describes that boundary.
Key facts
- Reese’s Law addresses button cell and coin battery ingestion hazards in consumer products.
- CPSC published the federal product performance and labeling rule in September 2023, codified at 16 CFR Part 1263.
- A UN 38.3 transport test summary does not replace finished-product evidence under Reese’s Law.
- Test report, CPC or GCC, packaging and warning artwork are related but distinct records.
- Product model, design, sample and production revision must be connected before an old report is treated as applicable.
FAQ
Does every product containing a button cell need the same test report?
No. Scope, product design, applicable exception, children’s-product status and the specific requirement determine the evidence route. The finished product and its battery compartment must be identified before a laboratory scopes testing.
Is a battery UN 38.3 test summary enough for Reese’s Law?
No. UN 38.3 addresses transport testing for cells and batteries. Reese’s Law and 16 CFR Part 1263 address consumer-product battery accessibility, warnings and related requirements; they answer different questions.
When is a Children’s Product Certificate required instead of a General Certificate of Conformity?
For a children’s product subject to an applicable children’s product safety rule, certification generally relies on testing by a CPSC-accepted third-party laboratory and uses a Children’s Product Certificate. Non-children’s products subject to a consumer product safety rule generally use a General Certificate of Conformity based on the applicable testing basis.
What should a laboratory request before quoting?
Request the exact product and model, age grading, battery type, battery-compartment design, applicable exception claim, production sample or lot, existing report and certificate, packaging and warning artwork, destination event and decision date.
