CPC for children’s chalk
Children’s chalk designed or marketed to children 12 and under are children’s products: they need third-party testing at a CPSC-accepted laboratory and a Children’s Product Certificate citing lead, dust, and art-material rules, plus tracking labels on the product and packaging. The importer or US manufacturer issues the CPC — marketplaces can request it at any time.
Which rules apply to children’s chalk
- Lead and heavy metals in each chalk color and binder; dust-inhalation consideration and art-material labeling.
- 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
Lead and heavy metals per color, dust-inhalation review through material composition.
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
Why does chalk have a lead history?
Cheap calcium sources and pigments have repeatedly tested positive for lead in import sampling.
Is dustless chalk regulated?
The lead and heavy-metal testing applies regardless of dust-reduction claims.
