California Prop 65: Overview, Recent Updates, and Solutions for Compliance

California Proposition 65 prohibits the sale of a product in California which knowingly and intentionally exposes an individual to a California Office of Environmental Health Hazard Assessment (OEHHA) listed chemical without a specific stated warning.

California Prop 65 is an important topic that involves legal, regulatory, and quality considerations, as companies can face serious penalties for violations. California Prop 65 can also spawn significant litigation.

  • The regulatory and legal background on California Prop 65
  • How chemicals are added to the California OEHHA list
  • Considerations for warning placement and labeling
  • Examples of Safe Harbor Level (SHL) testing for Prop 65 compliance
