Codes Used for Reporting Trade Data

Trade data is reported using classification schemes that are set up either to measure economic activity (industry-based schemes) or to monitor and measure trade for specific products (product-based schemes). This page provides information about such internationally used classification schemes as well as the main schemes used in the United States, and links to sites that deal with the relationships between national and international schemes

Code Schemes used by International Agencies

Code Schemes used by the United States

The United States uses its own product and industry coding structures for federal data gathering and reporting. Descriptions of these schemes and other trade-related coding schemes (not the actual code values) are located on the U.S. Classifications: The Basics page. Links to code lists in ascii format can be found on the Trade Codes page.

  • Industry-based codes
  • Commodity-based codes
    • Harmonized Tariff Schedule of the United States(HTS)

      Used for export data, this is a ten digit scheme with the first six digits corresponding to both the international HS scheme and the HTS scheme used for U.S. imports
