Using the Harmonized System

HS numbers are six-digit codes used to categorize products that are traded between countries.

They tend to focus on the raw materials that make up a product.

You will need HS numbers to determine tariff and license requirements for your product.

The United States assigns four additional digits to all HS numbers to create 10-digit Schedule B numbers

HS numbers are the same as Schedule B numbers for the first six digits
