All products sold in California must comply with Proposition 65 warning requirements. Proposition 65 is a “right to know” law that addresses consumer concerns about exposure to hazardous chemicals in consumer products.

As a result, the state of California is required to publish a list of chemicals that cause cancer, birth defects or other reproductive harm.

After a new chemical is added to the list, businesses have 12 months to comply with Proposition 65 warning requirements. Businesses that do not comply may be subject to risk of litigation from California’s enforcement community.
