California Proposition 65 overview and warning notices

What is Proposition 65?

California’s Proposition 65 (i.e., The Safe Drinking Water and Toxic Enforcement Act of 1986) is a law that requires warnings be provided to California consumers when they might be exposed to chemicals identified by California as causing cancer or reproductive toxicity. It stemmed from a ballot initiative passed by California voters in 1986, and is a toxic chemicals right-to-know law requiring a company doing business in California to place warnings on products and, if the product is sold on the internet, on web pages featuring the product. The law requires the warning when certain chemicals in the products are present in levels that could cause certain levels of exposure to the consumer. 

The California Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program and publishes the listed chemicals, which includes more than 950 chemicals. The law allows private enforcers to bring notices of violation of any of 950+ chemicals it regulates, which in turn requires Wish merchants, as one option, to add warnings that the product at issue contains specific chemicals that can cause cancer or reproductive harm.  Another option is to withdraw the product from California sale. Neither option exempts Wish merchants from liability for the period of time the product was sold to California consumers without a warning. The warning must be both on the product packaging and on the app product listing page where the product is featured.

Proposition 65 requires warnings for products that contain chemicals known to the State of California to cause cancer and birth defects, or other reproductive harm. Merchants must display the following warnings on both the product/product packaging labeling itself and online in their product listing, IF the products they sell contain chemicals in this list

Please Note: A California Proposition 65 violation can constitute a violation of Wish’s Merchant Terms of Service and Wish Merchant policies.
