After what has amounted to a multi-year rulemaking process, the California Office of Environmental Health Hazard Assessment (OEHHA) finalized amendments to the short-form warnings under Proposition 65 on December 6, 2024. The amendments (outlined in full here) require that short-form warnings include at least one chemical name, along with other options for safe harbor warning. There is also a specialized short-form warning for food. Specific long-form warnings were also added for Passenger, or Off-Highway Motor Vehicle Parts and Recreational Marine Vessel Parts. While the amendments become effective on January 1, 2025, OEHHA has provided businesses that currently rely on the existing short-form warnings three years (until January 1, 2028) to transition to the new short-form content.
