CPC for children’s slime

Children’s slime 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 LHAMA, lead, boron/chemistry, and children’s-product 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 slime

  • Slime products marketed to children draw art-material (LHAMA) review, heavy-metal screening, and formulation checks (including boron chemistry concerns in some recipes).
  • 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

Exact recipe as sold, colorants, glitter (coating lead), and age labeling. DIY slime kits need coverage for every included chemical packet.

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 do slime listings get pulled?

Formulation hazards, missing art-material labeling, and mismatched age grades are the usual reasons.

Does glitter slime need extra testing?

Glitter is a particulate coating — include it in heavy-metal screening.
