New California regulations provide more specific guidance on the content of Prop 65 "safe harbor" warnings, and on the corresponding methods for providing such warnings.

Come August 30, 2018, consumer products to be released into the California marketplace must meet new regulations under California's infamous Proposition 65.

On September 1, 2015, California enacted Senate Bill 633 ("SB 633"), loosening the state's restrictions on "Made in USA" labeling. Under existing law, codified at Cal. Bus. & Prof. Code § 17533.7, a product may not be sold or offered for sale in California as "Made in U.S.A" if the product, or any article, unit, or part of the product, has been entirely or substantially made, manufactured, or produced outside of the United States.
