The Harmonized Tariff Schedule of the United States (HTS) sets out the tariff rates and statistical categories for all merchandise imported into the United States. The HTS is based on the international Harmonized System, which is the global system of nomenclature applied to most world trade in goods. The HTS is an important resource for businesses engaged in the importation and exportation of goods in 2024, the HTS reached a major milestone, surpassing 10 million views on its web platform.
Maintained by the U.S. International Trade Commission (USITC), the HTS serves as the official compilation of tariff and statistical provisions for imported goods. Enacted by Congress, it became effective on January 1, 1989, replacing the Tariff Schedule of the United States. As directed by Congress under the Omnibus Trade and Competitiveness Act of 1988, the USITC publishes the HTSUS in print and online.
The enforcement and interpretation of the HTS fall under the jurisdiction of U.S. Customs and Border Protection (CBP), part of the Department of Homeland Security.
