Schedule B and Trade Information

About Export Codes

Export codes, also known as Schedule B numbers, are administered by the U.S. Census Bureau.

All import and export codes used by the United States are based on the Harmonized System (HS). The HS assigns 6-digit codes for general categories. This 6-digit code is known as the Harmonized System number.

Countries that use the HS are allowed to define commodities at a more detailed level than 6-digits, however all definitions must be within that 6-digit framework. The U.S., for example, defines products using 10-digit codes in its Harmonized Tariff Schedule (HTS).

Import codes are administered by the U.S. International Trade Commission (USITC).
