Schedule B is an industry classification system used for declaration of goods for exporting from the United States to other countries. It has a similar role as the HS classification in other countries.
Schedule B codes are 10-digit numbers, unlike HS codes, which are 6-digit. Schedule B codes classify a wide range of physical products from chocolate bars to airplanes and tanker ships.
Schedule B numbers are administered and used by several US government agencies, including the U.S. Commerce Department, Census Bureau, the U.S. Customs, and Foreign Trade Division to collect and publish U.S. export statistics. Schedule B codes are required to be reported in the Automated Export System (AES) when shipments are valued over $2,500 or the item requires a license.
