California Updates Proposed Proposition 65 Changes That Would Impact SEMA Businesses

By the SEMA Washington, D.C., office

Proposition 65

California's Office of Environmental Health Hazard Assessment (OEHHA) has proposed updates to its SEMA-opposed October 2023 amendments to Proposition 65, a California law that requires warning labels on products containing chemicals known to cause cancer, birth defects or reproductive harm. 

Proposed Modifications: 

  • Extended Implementation Period: The timeframe for implementing revised short-form warning content has increased from two to three years. 
  • Reversion to Original Text: Most internet and catalog warning content will revert to the original regulation text. 
  • Internet Retailers Grace Period: A new provision grants internet retailers a 60-day grace period to update their online short-form warnings once they receive a warning or written notice during the three-year implementation period. 

The changes, initially announced by OEHHA in October 2023, would significantly impact businesses in the automotive specialty-equipment industry, including manufacturers, distributors, retailers and out-of-state companies selling products in California.
