Type a chemical, a CAS number or a product code, and Sourzi puts every check it can run on one card: the chemical register, the duty, anti dumping cases and the supplier.
Each row shows the official file it came from and the date of that file. Where Sourzi does not hold the answer, the row says so instead of guessing.
China to the United States
Copper sulfate pentahydrate
CAS 7758-99-8 · Product code 2833.25.00 · Full CAS page
One row needs a check before you order, and one row is a gap Sourzi cannot fill yet.
TSCA (US register)
Not found
CAS 7758-99-8 is not in the stored copy of the TSCA inventory, the US chemical register. A miss is not a clearance: the public file leaves out confidential listings.
Sourzi does not store the Section 301 rate on goods of China yet, so this row is a gap, not a guess. Confirm the rate with your customs broker before you price the order. No stored Section 301 exclusion matches this code.
Add the supplier's company name to screen it against the DFAT sanctions list and the US UFLPA Entity List.

Duty rates, anti dumping cases and register listings change after you have checked them once. Sourzi is building a daily watch that emails you the day a row on this card changes.
Leave your email and you get one message when the watch is live for Copper sulfate pentahydrate, and nothing else.
