California Proposition 65

California Proposition 65 sets substance bans and restrictions for chemicals and heavy metals in consumer products sold in California, USA. Selling products containing restricted substances exceeding the set limits can result in warning labelling requirements.


Ideally, your supplier can provide test reports proving that their products or materials are compliant with California Proposition 65. However, this is relatively rare.

Lab testing

Your other option is to book third-party lab testing. Such testing services are provided by SGS, Intertek, and TUV Rheinland.
