U.S. Harmonized Tariff Schedule (online search)

The Harmonized Tariff Schedule of the United States (HTSUS or HTS) is a U.S. nomenclature system used to classify traded goods based on their material composition, product name, and/or intended function. The HTS is a 10-digit code designed so that each article falls into only one category. It is divided into chapters, each of which has a 2-digit number. Each product category within the various chapters is designated by 4, 6, 8, or 10 digits. The 4-digit categories are called headings. The 6-, 8- and 10-digit classifications are called subheadings. U.S. Customs and Border Protection (CBP) uses this system and its rules to classify imported goods. HTS codes are also used to determine duty rates applied to imported goods. Nearly every good that is imported into the United States is classified in an eight-digit category.
