HTS classification reference
A text match is only a starting point. Accurate tariff classification also depends on product facts, the legal hierarchy of the schedule, section and chapter notes, and relevant customs guidance.
An HTS code is a 10-digit classification number used for goods imported into the United States. The code identifies the product and helps determine its tariff treatment, duty rate, reporting requirements, and any special provisions that may apply.
The Harmonized System, or HS, provides the first six digits used internationally. The United States extends that structure to 10 digits in the Harmonized Tariff Schedule, or HTS, to define U.S. tariff lines and statistical reporting categories.
Search by a product description or known code, then review the surrounding headings, subheadings, section notes, chapter notes, duty rates, and relevant customs guidance. Product composition, principal function, construction, and intended use can all affect the final classification.
