Customs Classification

The U.S. International Trade Commission (USITC) publishes and maintains the U.S. Harmonized Tariff Schedule (HTS) and provides technical information on its structure and modification.

However, the Bureau of Customs and Border Protection (CBP) of the Department of Homeland Security is solely authorized to interpret the HTS, to issue legally binding rulings or advice on the tariff classification of imports and their treatment upon entry into the United States, and to administer the customs laws.
