United States
California Proposition 65
Proposition 65 requires a clear and reasonable warning before knowingly exposing anyone in California to a listed chemical known to the state to cause cancer or reproductive harm. The list runs to roughly a thousand substances and is updated through the year. Enforcement comes substantially from private plaintiffs issuing 60-day notices rather than from a regulator, which is why exposure here is commercial and immediate even where the underlying risk is contested.
What it obliges you to do
- Screen products against the current listed-chemicals list
- Provide a compliant warning where an exposure requires one
- Keep evidence supporting any no-warning determination
- Monitor new listings and their twelve-month grace periods

No machine-readable feed reaches Prop 65 yet. We ingest the US Federal Register and legislation.gov.uk; neither carries instruments under this name, and the EU publishers that would — ECHA, EUR-Lex, the Commission — refuse automated requests. The primary sources above are the record to watch. This is a gap in available feeds, not an indication that nothing is changing.
