CPC for thinking putty and kids’ putty
Which rules apply to thinking putty and kids’ putty
- Putty marketed to children needs art-material evaluation and heavy-metal screening; magnetic or color-changing putties add specialty component review.
- CPSIA section 101 total lead content in accessible substrate materials.
- 16 CFR part 1303 lead in paint and surface coatings where painted or coated.
- CPSIA section 103 tracking labels: manufacturer, location, and date of manufacture on product and packaging.
The testing and certification path
Base polymer chemistry, pigments, and any magnetic additives (magnet rules may apply).
Book testing at a laboratory that is CPSC-accepted for each rule, issue the CPC in your own name citing the rules your report supports, and keep the certificate with its test report for at least five years. Marketplaces ask for the pair, not the certificate alone.
Questions people ask
Are adult desk putties exempt?
If marketed to adults and not children, children’s-product CPC duties may not apply — but child-targeted listings do.
Does magnetic putty need magnet testing?
If it contains magnets or magnetic particles posing ingestion hazards, evaluate magnet requirements with your lab.
