Which rules apply to marble runs
- Small parts on every track piece and connector, magnet security, lead in substrates and coatings, structural review.
- CPSIA section 101 total lead content in accessible substrate materials.

The testing and certification path
Marbles and component small-parts review, magnet containment, track connection integrity.
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.
