Some HTS codes covering button cell batteries are on CPSC's eFiling flagged-code list, under the category "Button Cell & Coin Batteries." CPSC uses the list to flag codes when goods arrive. A product under a flagged code may need a certificate, may fall under no certificate rule, or may be one CPSC lets go without a certificate; which case fits depends on the product itself, not the code.
The codes CPSC flags here (HTS heading 8506) are for button and coin cells themselves, which fall under 16 CFR 1263.4, the Reese's Law rule for warning labels on the batteries' packaging. A product that holds or runs on a button or coin cell, even one sold without the battery, falls under 16 CFR 1263.3, the product-side rule for the battery compartment and its labelling, and a product sold with spare cells packed separately falls under both. Zinc-air cells are outside the rule.
The free certificate check gives a product-level answer -- which standards apply, which are excluded, and whether the result points to a certificate or a disclaim -- based on the specific product's own attributes, not just its HTS code.

Verdicts in this report are produced by deterministic code, not by a language model. The explanatory paragraph accompanying each check is model-generated and checked against the cited sources before delivery. No part of this report is reviewed by a person before it is issued, so every material finding and citation should be confirmed against the underlying government source before it is relied on.

Users should re-screen periodically and consult qualified counsel for compliance decisions.
Name-similarity results do not establish or rule out the identity of any company. Where multiple similarly named records exist, none should be treated as confirmed without independent verification against the primary government source.
