What is California Prop 65?

California Prop 65 regulates substances listed by California’s Office of Environmental Health Hazard Assessment (OEHHA) as potentially dangerous. Further, Prop 65 prohibits businesses from knowingly exposing individuals to those substances without first providing a clear and reasonable warning.


Initially passed in 1986 to limit the lead content in drinking water, the law has been expanded to apply to consumer products as well. While similar to the Consumer Product Safety Improvement Act (CPSIA), California’s Prop 65 requires that businesses operating in California include a certificate stating that consumer products originating from there have passed Prop 65 safety standards.

We work with suppliers from all over the country, but we try our best to work most with suppliers active in the Quality Certification Alliance, an industry group devoted to enforcement of CPSIA, California Prop 65, and other product safety laws.
