Sanctions & Tariff Lookup

Sanctions & Tariff Lookup gives Claude read-only access to two public U.S. government datasets used in trade compliance.

Screening: names are fuzzy-matched against the Consolidated Screening List published by the U.S. International Trade Administration. It combines the export screening lists of the Departments of Commerce, State and the Treasury: OFAC's Specially Designated Nationals (SDN), Sectoral Sanctions and other Treasury lists, the BIS Entity List, Denied Persons, Unverified and Military End User lists, and State Department ITAR debarments and nonproliferation sanctions. Matching covers primary names and aliases and tolerates differences in case, accents, punctuation, word order, company suffixes (LLC, Ltd, GmbH, OOO, PJSC), small typos, Cyrillic input, common transliterations and added place or office words ("Rosneft Moscow", "Bank Melli Iran, Hamburg branch"). Each possible match shows its score, the alias that matched, the list and programs, addresses, countries, IDs, a link to the official entry and the list's as-of date. Names with no match get a clear 'no match at this threshold' answer. Up to 25 names can be screened in one call.

Tariffs: search the current Harmonized Tariff Schedule of the United States (USITC) by product words, or look up any 4-10 digit HTS code for its description, hierarchy, general, special and column 2 duty rates, units, footnotes and Chapter 99 cross-references. Codes that cover several lines, such as Chapter 99 groups, list the lines they cover.

Every answer names its source and data date and includes a human-review notice. Results are possible matches and reference data, not legal advice or a compliance determination. Limits: U.S. lists only; ownership-based restrictions such as OFAC's 50 Percent Rule are not detected; Chapter 99, antidumping and countervailing duties are referenced but not calculated. Free, no account needed.
