Paste a material list. You get the flag count, the jurisdictions, and the dates,
computed against published restriction lists. No account, nothing stored.
What this does and does not tell you.
This checks the substances you supply against published restriction lists. It is not a
discovery of your bill of materials, and it cannot see anything you do not paste in.
A clean result is not a clean bill of health. A material can come back
unflagged because it is genuinely unlisted, because it sits on a list not covered here, or
because it is regulated as a class rather than by CAS. PFAS coverage in particular is
substance-level: the well-characterised ones resolve, the class runs to roughly 15,000
substances. Treat an unflagged row as not yet identified, never as cleared.
Coverage here is deepest on the California Prop 65 list and the ECHA candidate list. Dates
move, and several of these have already been extended more than once. Confirm against the
live regulation before relying on one for a filing.
