California Proposition 65 Compliance Statement & Information

Businesses in California must inform customers about the presence of chemicals known to cause cancer, congenital disabilities, or other reproductive damage per Proposition 65. Consumer goods, indoor air, and outdoor runoff are all potential sources of exposure to these chemicals for Californians. Proposition 65 equips Californians to make well-informed choices regarding their chemical exposure by mandating the disclosure of this data.

It is illegal for companies in California to intentionally release any of the chemicals on the Proposition 65 list into water supplies.

Per Proposition 65, California must disclose any substances known to the state to cause cancer, fetal damage, or other reproductive harm. Since its inception in 1987, this list of compounds that needs annual updating has expanded to include almost 900 different substances.

Voters in California supported Proposition 65 by a 63 percent to 37 percent majority in November 1986, making it law. The Safe Drinking Water and Toxic Enforcement Act of 1986 is most commonly known as Proposition 65.

The following California 65 compliance statement must appear for all items containing stainless steel, sluminum, copper, and brass (sheet and coil), foam packaging, wood packaging, and oil:
