California’s Office of Environmental Health Hazard Assessment (OEHHA) recently posted a question and answer document regarding warning requirements that will apply to businesses beginning August 30, 2018.

OEHHA’s new regulations place primary responsibility for providing warnings on product manufacturers, producers, packagers, importers, suppliers or distributors.

Specifically, suppliers of ingredients that contain a listed PROP 65 chemical would only have responsibility for a consumer warning if it has knowledge that the end use of the component part or ingredient will expose a consumer to the listed chemical at a level that requires a warning.

Consumer products manufactured prior to August 30, 2018, and labeled with a warning that is compliant with the September 2008 version of the regulations will be considered in compliance with the 2018 regulations. Additional PROP 65 guidance information will be provided by OEHHA prior to the 2018 compliance deadline.
