HTSUS codes

Harmonized Tariff Schedule of the United States (HTSUS) codes are 10-digit codes (e.g., 0901.21.0045) used to identify products. They may be called HTS codes for short. HTS codes are U.S.-specific and are used for import into the U.S. They are administered by the U.S. International Trade Commission (ITC).

An HTS code takes the same form as an HS code for the first six digits and then has four differing last digits. It’s very important that all U.S. importers know and use the correct HTS codes because commodity duties are assessed based on this classification. With some limited exceptions, HTSUS codes can also be used by U.S. exporters on their export paperwork.
