CPC for stacking rings
Which rules apply to stacking rings
- Classic stacking rings need mechanical toy testing, chemistry on plastic/wood rings, and age-appropriate small-parts 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
Rod security, ring integrity after bite, and finish lead on painted wood sets.
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.
