This page consists of the most recent online versions of the Harmonized Tariff Schedule, which may be an updated version of the last printed publication. Usually, the links provided will be either to the basic annual edition or its supplement(s), although there are intermediate electronic revisions that may be available. The USITC (Office of Tariff Affairs and Trade Agreements) is responsible for publishing the Harmonized Tariff Schedule of the United States Annotated (HTSA). The HTSA provides the applicable tariff rates and statistical categories for all merchandise imported into the United States; it is based on the international Harmonized System, the global system of nomenclature that is used to describe most world trade in goods.Although the USITC publishes and maintains the HTSA in its various forms, Customs and Border Protection is the only agency that can provide legally binding advice or rulings on classification of imports. Contact your nearest Customs office with questions about how potential imports should be classified. For a binding ruling on classification, contact the Bureau of Customs and Border Protection.The Harmonized Tariff Schedule is available from the Government Printing Office in hardcopy form. If you would like to order a subscription to the latest printed edition, the 2007 HTS can be ordered from http://bookstore.gpo.gov using stock number 949-023-00000-1.
