Reese's Law
Reese's Law is the 2022 US law, named after a child who died after swallowing a button battery, that requires child-resistant battery compartments, warnings and packaging for button and coin cell batteries and products containing them.
What it requires
Under CPSC's standard at 16 CFR Part 1263, effective 19 March 2024, consumer products containing or designed to use button or coin cell batteries must have battery compartments that resist child access, pass abuse tests, and carry warnings on the product, packaging and instructions. Since 2023, button and coin batteries sold alone must be in child-resistant packaging under the Poison Prevention Packaging Act. Products must be tested by an accepted third-party lab and certified, and noncompliant products are subject to recall.
Why it matters
Reese's Law reaches a wide range of everyday products sold online, such as remote controls, key fobs, toys, kitchen scales and flameless candles. Each needs a compliant battery compartment, warnings and third-party test certification before import. For example, a seller of LED tea lights that include coin cell batteries must have them tested to 16 CFR 1263 and packed with the required warning labels, and the importer must issue a certificate and eFile its data at entry.
