Formerly known as the Safe Drinking Water and Toxic Enforcement Act of 1986, California Proposition 65 (or simply Prop 65) is a law that requires businesses to notify California residents of significant exposure to hazardous chemicals used in their products. These substances could cause cancer, birth abnormalities, or other reproductive harm. Companies should give these notifications through clear and reasonable warnings.
Regardless of whether a company has a physical presence in California, this regulation applies to products placed in the California Market. Additionally, Prop 65 applies to California businesses with 10 or more employees involved in the supply chain for products sold in this state. Correspondingly, all supply chain participants, including producers, distributors, suppliers, retailers, and packagers, are responsible for implementing Prop 65 requirements.
