What is a harmonized system number?
Harmonized system (HS) numbers are classification numbers assigned to identify a specific type of product. The HS number is used by Customs authorities to apply duties and taxes. These numbers are typically 6 to 10 digits long. The first six digits are standardized worldwide, while additional numbers are used by some governments to further distinguish products in a certain category. In the United States, HS numbers are also called Schedule B numbers. To provide tariff information, the six-digit-level HS number is required. The U.S. Census Bureau’s Foreign Trade Division Web site can be used to classify products in the HS. Visit their searchable Schedule B export codes.
