How complete is the schedule?

All 35,804 lines of the official USITC schedule across 98 chapters, including 19,949 ten-digit statistical lines, with headings, subheadings, units of quantity, quota quantities, additional duties and footnotes.

Which duty rates are included?

The general most-favoured-nation rate, the special rates for free-trade programmes such as USMCA, Korea and Australia, and the column 2 rate, exactly as published by the USITC.

Why does searching 'smartphones' find a line described only as 'Other'?

Every line stores the breadcrumb of its parent headings, so search runs over the description and that context together. A leaf called Other under 8517.13 is found because its ancestry mentions smartphones.

How often is it updated?

The schedule is re-synced nightly from the USITC export, so revisions and new statistical lines appear the day after publication.

Does it cover other countries' tariffs?

No. This is the US schedule only. The first six digits of any HTS code are the international HS code, which is the same worldwide, but national subdivisions and rates differ by country.

Tariff Codes API

All 35,804 lines of the US Harmonized Tariff Schedule with duty rates, searchable

The complete US Harmonized Tariff Schedule, searchable. All 35,804 lines of the official USITC schedule across 98 chapters — headings, subheadings and 19,949 ten-digit statistical lines — each with its full duty-rate columns: general (MFN) rate, special FTA program rates (USMCA, Korea, Australia...), the column 2 rate, units of quantity, quota quantities, additional duties and footnotes (including Section 301 references). Every line carries a breadcrumb of its ancestors, so a leaf named simply 'Other' is searchable and meaningful, and full-text search covers descriptions AND that inherited context — searching 'smartphones' finds 8517.13.00.00 (Free), 'portable automatic data processing' finds the laptop line 8471.30.01.00. Look any code up by digits with or without dots (8703.23.01 → passenger vehicles at 2.5% with ancestors and child statistical lines), filter by chapter or code prefix, browse all chapters with WCO section titles. Re-synced nightly from the USITC export, so the ~10-15 yearly HTS revisions reach you at most a day late. The classification backbone for cross-border e-commerce, customs brokers, landed-cost calculators and trade compliance tooling.
