California Proposition 65, also known as California Proposition 65, or CA65, CP65, or Prop65, is a chemical certification in the United States that tests the limit values of total lead, total cadmium, phthalates, BPA, and other chemical items in products.

In November 1986, California voted to pass the Safe Drinking Water and Toxic Substances Enforcement Act, which is known as California Proposition 65.

1. The purpose of the proposal.

Is to protect California's drinking water sources from contamination by chemicals known to be carcinogenic and reproductive toxins, and to protect public health. The proposal requires businesses to warn consumers of the presence of known toxic chemicals in their products through clear and reasonable labeling. Currently, there are more than 900 chemicals on the chemical list that California considers to be carcinogenic or reproductive toxic. California Proposition 65 affects all products sold in California.

2. Products covered by the proposal.

Jewelry, toys, electrical devices, glass-ceramic materials, clothing, accessories, pharmaceuticals, pesticides, dyes, cosmetics, gifts, manufacturing or construction supplies, byproducts of chemical processes such as automobile exhaust, fumes, and natural gas flaring, covering virtually all products and listing exposure scenarios for hazardous materials.

3. The core requirements of the proposal.

1) Do not allow the discharge of hazardous substances listed in the proposal into drinking water.

2) Provide clear and reasonable warnings (for listed substances, warnings are required unless the exposure level is so low that it does not pose a risk). Warning labels can be placed on the product, in the workplace, in retail stores, or distributed in notices, printed in newspapers, and generally recommended on the product. The main content of the label is to describe that the product contains lead.
