What the stored files say about a chemical

Paste a name or a CAS number. The page only knows the five names cached from PubChem. Each flag comes from a file already on this site. A miss is not a clearance.

The first 3 lines run free. Pro runs up to 50.

Ready.

Not checked here: an Australian drug precursor permit, a US pesticide flag, a dangerous goods class, and a forced labour sector list. Those files are not stored. There is no PDF on this page.

Want a factory that passes these checks?

Tell us the chemical, grade and quantity. A person on our team in Shanghai sends you a real, checked factory, and your first one is free.

Sourzi shows what official files say. It is not customs or legal advice. For a binding answer, ask a licensed customs broker, a CBP ruling or an Australian Border Force Tariff Advice.
