Changes You Need to Know About Proposition 65


The revised Proposition 65 notice regulations went into effect in California today, August 30th. The updated regulation requires businesses to provide notice of potential exposure to specific, potentially harmful chemicals that are included on the list maintained by the state. The new notice also requires a warning symbol on certain products and locations if the potential exposure exceeds certain levels.

Some new features include:

  • Requiring a warning triangle sign to precede Proposition 65 warnings (except for warnings on foods);
  • Changing the wording of the warning to state “This product can expose you to” rather than “This product contains;”
  • Requiring the disclosure of the identity of at least one chemical per toxicity endpoint in the warning;
  • Including a link to the “Lead Agency Website” ( that offers additional information on Proposition 65 and listed chemicals;
  • Providing the option of a short form warning (subject to minimum type size requirements) when providing the warning on the product or its immediate container;
  • Requiring warnings for internet and catalog sales;
  • Requiring warnings in foreign languages if other “consumer information” is provided in foreign languages.
