What is a 6 digit HTS Code or HS Code?

The 6 digit HS Code or HTS Code is called a sub-heading. It comes after chapter (2 digit) and the heading (4 digit) in the HS Code hierarchy. Till 6 digits HS Codes remain the same globally. It is only after the 6 digit level that the HS Codes start varying for each country,

Check country-specific US tariffs: the HTS duty rate is only part of what you pay. Depending on the country of origin, imports can also face additional duties such as Section 301 or Section 232 tariffs. See current rates by country and product in our US tariff calculator.

How to find the US import duty or customs duty from this page?

  • Identify your product's 6 digit HTS Code or HS Code from the above list

  • Now, you have to identify the 8 digit code of your product as all the import duty tariffs in the HTS US are listed at 8 digit HTS Code.

  • Click on the HTS 6 you have selected for your product, it will take you to a list of 8-10 digit HTS Codes where you will also find your product's import duty rate.

  • Alternatively, you can also click on "View Import Duty" which will give you a preview of some of the 8 digit HTS Codes with import duty. Click on "View all" to see the complete list.
