Question

What is Prop 65 labeling requirements?

Answer

Proposition 65, formally the Safe Drinking Water and Toxic Enforcement Act, requires businesses to warn Californians about significant exposures to chemicals known to cause cancer, birth defects or other reproductive harm. If your product falls under these rules, a compliant warning label needs to appear on the packaging.

  • Who it applies to: businesses selling covered products into California.
  • What it warns about: listed chemicals linked to cancer or reproductive harm.
  • What the label must include: the required warning symbol, wording and, where applicable, the specific chemical name.

Because the exact wording and format are set by regulation, confirm the current requirements for your product category, then supply that approved text in your artwork so it prints exactly as specified.
