Learn how to determine your HS Code and Schedule B numbers.

Harmonized System (HS) codes are a standardized numerical method of classifying traded products. They are 6 digits and standardized across countries. Schedule B numbers contain 10 digits. The first 6 digits are the same as the HS code; the last 4 digits are used by the U.S. to further classify exported products.

Exporters need to know their product’s Schedule B and HS numbers to:

• Determine applicable import tariff rates and whether a product qualifies for a preferential tariff under a Free Trade Agreement
• Complete Electronic Export Information, Certificates of Origin and other shipping documents
• View import and export data for a specific product to determine trends and top markets
