What are HS codes?
HS codes are product classification numbers used in international trade. The Harmonized System is maintained by the World Customs Organization and is used by customs authorities, importers, exporters, freight forwarders, and trade compliance teams to describe goods in a consistent way.
An HS code usually starts with a 6-digit international classification. Countries often add more digits for their own tariff schedules, statistical reporting, duty rates, and import or export controls. In the United States, import classifications are commonly listed as HTS codes and export classifications are commonly listed as Schedule B codes.
What they are used for
HS codes help identify the product being shipped, estimate customs duty, prepare import and export documents, compare tariff treatment, and check whether special trade programs may apply.
How to search
Search by a code such as 85371090, by a formatted code such as 3926.90, or by a product description such as control panels, plastic boxes, valves, printed books, medical instruments, or aluminum structures.
Before shipment
Tariff classifications and duty rates can change. Use this lookup as a research starting point, then verify the final classification with the current official tariff schedule, a customs broker, or the relevant customs authority.
