CPC for children’s pottery kits

Children’s pottery kits 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, heavy-metal, and small-parts 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 pottery kits

  • Children’s pottery and clay kits test the clay and glazes for heavy metals (lead and cadmium in particular), small parts on tools and embellishments, and LHAMA labeling if paints are included.
  • 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

Testing covers lead and cadmium in the clay body and any glaze or paint components — ceramic chemistry is the known hazard — plus small parts on included tools and decorations, and LHAMA labeling duties where paints or finishes are in the box.

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

Does air-dry clay need heavy-metal testing?

Yes: clay bodies and colorants are screened for lead, cadmium, and other elements. “Non-toxic” claims require the test file behind them.

Are the finished (baked) pieces re-tested?

Curing can change surface chemistry — labs typically test both the raw material and finished samples. Confirm the protocol with your laboratory.
