California Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, is a law designed to protect California residents from exposure to chemicals known to cause cancer, birth defects, or other reproductive harm. This regulation applies to all products sold in California, including textiles, metal goods, toys, juvenile products, and electronic and electrical products.

Failure to comply with Proposition 65 can result in severe consequences, such as:
- Product listings being removed
- Temporary Restraining Orders (TRO) and lawsuits
- Sales bans
- Funds being frozen
- Store suspension
For cross-border sellers, understanding and complying with Proposition 65 is crucial to avoid these risks.
Conduct product testing to determine whether they contain chemicals listed under Proposition 65 and assess their concentration levels. It is recommended to obtain existing test reports from suppliers or conduct independent testing at an accredited third-party laboratory.
Ensure compliance both online and offline by adding clear warning labels on product packaging, user manuals, or sales pages.
If compliance is not feasible, sellers may opt to disable shipping to California to mitigate legal risks.
If you prefer not to include warning labels on your products, ensure that they do not contain restricted substances above the Safe Harbor Levels. Testing for volatile organic compound (VOC) emissions or similar chemical tests can help determine compliance.
Ensuring compliance with Proposition 65 not only helps avoid legal consequences but also enhances consumer trust in your brand. By thoroughly understanding regulatory requirements, conducting comprehensive testing, designing warning labels, implementing continuous compliance management, and preparing for potential legal risks, businesses can minimize legal disputes, protect consumer health, and strengthen brand reputation.
If your product contains substances regulated under Proposition 65, it is advisable to conduct preliminary testing for awareness. Sellers requiring Proposition 65 compliance testing can contact us via email or leave a message, and we will promptly provide a testing plan and cost estimate.
