How to find the HS code for your product
An HS code (Harmonized System code) is the number customs uses to classify a product and set its duty. The US uses a 10-digit version called the HTS code. Type what you sell below to find the right US code and its import duty rate.

How HS and HTS codes work
- First 6 digits = HS code, shared by ~200 countries. The US adds 4 more digits to make the 10-digit HTS code that sets the exact US duty.
- Structure: chapter (2) → heading (4) → subheading (6) → US tariff line (8) → statistical suffix (10). See how to read an HTS code.
- The duty depends on origin. On top of the base (MFN) rate, goods from some countries carry Section 301, 232, or IEEPA add-on duties — every code page shows the rate in effect by country.
- Classification is the importer's responsibility. When unsure, a licensed customs broker or a CBP binding ruling can confirm the code.

Common questions
Is an HS code the same as an HTS code?
They share the first 6 digits. "HS code" refers to the international 6-digit Harmonized System number; the US "HTS code" extends it to 10 digits to set the exact US import duty. For US imports you ultimately need the 10-digit HTS code.
How many digits is a US import code?
Ten. The first 6 are the international HS code, digits 7–8 are the US tariff line that carries the duty rate, and digits 9–10 are a statistical suffix used for reporting.
How do I find the HS code for my product?
Search by a plain description of what the item is made of and what it does (for example "stainless steel vacuum insulated bottle"), then open the matching code to confirm the legal description fits your product. Material and construction usually decide the code.
What happens if I use the wrong code?
The wrong code can mean the wrong duty, penalties, or shipment delays. Classification is the importer's legal responsibility; when a product could fall under more than one code, a licensed customs broker or a CBP binding ruling can confirm it.
