Proposition 65: Clear and Reasonable Warnings – Safe Harbor Methods and Content
The Office of Environmental Health Hazard Assessment (OEHHA) has amended Title 27, California Code of Regulations sections 25601, 25602, 25603, and 25607.2, and added new sections 25607.50 through 25607.53.
This regulatory action will make the Proposition 65 short-form warning more informative to consumers by adding at least one chemical name and providing additional warning options for businesses to select from. The regulations provide businesses that currently rely on the existing short-form warnings three years to transition to the new short-form content, make explicit that short-form warnings may be used to provide safe harbor warnings for food products, provide a 60-day transition period, during the three-year implementation period for retailers to update online short-form warnings after notice from a manufacturer, and provide new tailored safe harbor warnings for passenger or off-highway motor vehicle parts and recreational marine vessel parts.
Final Approval/OAL Action
The Office of Administrative Law (OAL) approved the rulemaking on November 26, 2024. The effective date for the regulation is January 1, 2025. The final documents are posted here.
