US HTS Code Directory & Duty Rates

The Harmonized Tariff Schedule of the United States (HTSUS) is the primary resource for determining tariff classifications for goods imported into the US. The first 6 digits represent the international standard Harmonized System (HS) code, digits 7–8 determine the US duty rate, and digits 9–10 are statistical reporting suffixes.

Under the Trade Act of 1974 Section 301, US Customs assesses additional tariffs (typically 7.5% or 25%) on thousands of HTS subheadings originating in China. These surcharges are additive on top of the standard Column 1 General duty rate unless the product has an active USTR exclusion.

Importers can submit an eRulings request directly to US Customs and Border Protection (CBP) National Commodity Specialist Division (NCSD) to obtain a binding ruling letter (CROSS database) establishing legally binding HTS classification prior to commercial import.
