About Harmonized Tariff Schedule

The Harmonized Tariff Schedule of the United States (HTS) was enacted by Congress and made effective on January 1, 1989, replacing the former Tariff Schedules of the United States.

The USITC maintains and publishes the HTS (in print and on-line) pursuant to the Omnibus Trade and Competitiveness Act of 1988; see the preface to the HTS for additional explanatory material. However, Customs and Border Protection of the Department of Homeland Security is responsible for interpreting and enforcing the HTS.

This page provides access to the most recent online version of the Harmonized Tariff Schedule (HTS) as well as  access to the individual chapters, notes, appendices which comprise the current version of the HTS in downloadable PDF format.
