Harmonized Number Classification

For every item, there is a customs classification number that ensures that customs authorities recognize the product and that the appropriate customs fees are assessed. These numbers are also used to obtain tariff rates, complete export documentation (such as certificates of origin) and for market research.
The Harmonized Tariff System (HTS) assigns a number to each product that is traded internationally to insure that customs officers and statisticians around the world are referring to the same thing when classifying a product. Almost all countries now use the harmonized tariff system.

The Harmonized Tariff System Number, or HTS number, refers to a six digit product-specific code. All countries adhering to the HTS use the same six digit code for each product. Each country, however, can assign on its own four additional numbers, making the entire number 10 digits. The United States does this with its Schedule B system, which is used to describe exports from the U.S. Many countries, though, do not use 10 digits; some use only six or eight.

Exporters need to know the HTS/Schedule B number for their products for several reasons.

• The HTS number is needed to complete the Shipper’s Export Declaration.
• The HTS number may be needed on shipping documents, including certificates of origin.
• The HTS number is needed to determine whether a product qualifies for a preferential tariff under the North American Free Trade Agreement.
   

The Bureau of the Census can help classify products and find the appropriate HTS number. The first step is to attempt to self-classify on the Census Bureau web site at: http://www.census.gov/foreign-trade/schedules/b/.
