The first step in any export or import transaction is to classify your product. The standard product classification system used by countries worldwide is the Harmonized System developed by the World Customs Organization.
You will need to know your product's HS Code in order to gather international trade statistics, research tariffs and tax rates, file documentation papers and complete many other parts of the export/import process.
How Do the Codes Work
Codes represent products in a standardized way. Two digit codes represent broad general product categories. Additional digits are added for detailed product classes. For example, in the Harmonized System (HS),
04.06 is the class number for Cheese
0406.20 is the class number for Grated or powdered cheese
HS Codes In the United States - The United States uses a modified form of the Harmonized System (HS) as the basis for its classification of imports and exports. The U.S. adds additional digits to the 6-digit HS code to identify products unique to U.S. markets. Exports are classified using Schedule B and imports are classified with the Harmonized Tariff Schedules (HTS).
This 5 minute video from the U.S.International Trade Administration (ITA) shows how to find your product's HS Code and for U.S. exporters, the product's Schedule B Code.
