Import Card

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

Citric acid

CAS 77-92-9 · Product code 2918.14.00 · Full CAS page

One row needs a check before you order, and one row is a gap Sourzi cannot fill yet.

  1. TSCA (US register)

    Listed

    CAS 77-92-9 is on the TSCA inventory (ACTIVE), the US chemical register.

    EPA TSCA inventory · file dated 22 Jul 2026

  2. US general duty

    Known

    US general duty for 2918.14.00.00: 6%.

    USITC tariff extract · file dated 25 Sep 2026

  3. Section 301 (China)

    Not stored

    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.

    HTSUS chapter 99

  4. Anti dumping (US)

    Case on file

    US anti dumping or countervailing cases on goods of China are stored under heading 2918: A-570-937, C-570-938. A heading match is not a scope ruling, and the rate depends on the producer. Check the case on ACCESS before you order.

  5. Supplier check

    Add supplier

    Add the supplier's company name to screen it against the DFAT sanctions list and the US UFLPA Entity List.

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.
