The Safe Drinking Water and Toxic Enforcement Act of 1986 (California Proposition 65)

According to the requirements of California Proposition 65, the California government updates a list of chemical substances annually. Currently, over a thousand chemical substances have been listed. The proposition mandates that 12 months after a chemical substance is added to the regulated list, if a product contains these chemical substances and poses an exposure risk to consumers, the manufacturer must post a warning label. Otherwise, they may face risks such as lawsuits and heavy compensation claims.


Applicable Product Scope for California Proposition 65:

Electrical and electronic products and their raw materials, children's and adult clothing, raincoats, footwear, aprons, napkins, tablecloths, pillows, mats, carpets, cushions, wallets, handbags, backpacks, and more.


Common Testing Items for California Proposition 65:

  1. Heavy Metals: such as lead, cadmium, etc.

  2. Phthalates

  3. Formaldehyde

  4. Flame Retardants

  5. BISphenol A (BPA)


Frequently Asked Questions about California Proposition 65 Testing:

Under what circumstances is a warning label required?

Answer: When a product contains chemical substances from the list, a warning label must be affixed. Otherwise, if a lawsuit is filed and the product is deemed to potentially cause harm, the manufacturer can be subject to severe financial penalties.


Does California Proposition 65 have limit requirements for the chemical substances on the list?

Answer: No. California Proposition 65 emphasizes the public's "Right to Know." Whether a product's chemical limits meet safety standards should be determined by referencing other U.S. regulations (such as cpsia, etc.) or by referring to past litigation
