OEHHA’s amendments to the Proposition 65 'Clear and Reasonable Warnings' regulations (safe-harbor warning methods and content) were approved by the California Office of Administrative Law (OAL) on Nov 26, 2024 and became effective Jan 1, 2025. This affects how businesses may satisfy safe-harbor warning requirements for Proposition 65 exposures in California, and compliance programs should align warning language, format, and delivery methods with the amended safe-harbor provisions and transition details described in OEHHA’s rulemaking record.
The Office of Administrative Law approved OEHHA’s rulemaking updating the Proposition 65 ‘clear and reasonable warnings’ regulation (safe harbor warning methods and content). The amendments became effective January 1, 2025, impacting how businesses may structure compliant warnings (including content and format elements) for listed-chemical exposures in California.
OEHHA adopted amendments to Title 27, California Code of Regulations sections 25601, 25602, 25603, and 25607.2, adding new sections 25607.50-25607.53 governing short-form warning statements. The amendments were approved by the Office of Administrative Law on November 26, 2024 and became effective January 1, 2025. A three-year implementation period allows businesses to transition until January 1, 2028, after which the old short-form warning format may no longer be used. The amendments also add new tailored safe harbor warnings for passenger and off-highway motor vehicle parts and recreational marine vessel parts.
