The U.S. HTS codes are managed by the U.S. International Trade Commission (USITC). They ensure these codes are connected to the correct tax and duty laws for your products.

U.S. HTS codes are 8 to 10 digits long, and using the right ones is essential to avoid shipment errors and delays.


The Harmonized Tariff Code is a 10-digit number that classifies goods for import and export. The first six digits are the HS (Harmonized System) code, which is standardised internationally, while the last four are specific to the United States.

Heading (Digits 3-4): The next two digits narrow the category to a specific product type. This part is also consistent globally.
Subheading (Digits 5-6): The following two digits provide further detail about the product and remain the same worldwide.
Subheading (Tariff Rate Lines) (Digits 7-8): These digits are specific to the U.S. and are used to establish import duty rates.
