US Tariff HTS Code Lookup & Import Duty API

Search official U.S. International Trade Commission HTS classification lines by HTS code prefix or product description. Returns source-linked tariff descriptions, units, general and special duty rates, and column 2 rates for import classification and landed-cost research. Deterministic test: htsCode=8507.60&maxResults=1 returns HTS 8507.60.00 for lithium-ion batteries with the published 3.4% general rate. Results are published classification/rate evidence, not a binding CBP ruling, legal advice, a complete landed-cost calculation, origin or FTA proof, or a guarantee of duty owed; Chapter 99 duties, exclusions, quotas, trade remedies, valuation, origin, and revisions can change treatment.
