California Proposition 65 Warning

Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted as a ballot initiative in November 1986. The proposition protects the state's drinking water sources from being contaminated with chemicals known to cause cancer, birth defects or other reproductive harm, and requires businesses to inform Californians about exposures to such chemicals. These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment. By requiring that this information be provided, Proposition 65 enables Californians to make informed decisions about their exposures to these chemicals.

Products sold, manufactured, and used by Circuit Motorsports Corp. may fall under the labeling requirements for California’s Proposition 65. Those products will have clear and reasonable warning labeling on the products web page(s) and packaging of the part. Consult with the part manufacturer for these warning and any information. The warning will feature a warning symbol followed by text similar to:
