What are HTS Codes?
Harmonized Tariff Schedule (HTS) codes are 10-digit product classification codes used by US Customs and Border Protection to determine import duties. Every product imported into the United States requires an HTS code.
Why HTS Codes Matter
- Required for US customs clearance
- Determines import duty rates
- Ensures regulatory compliance
- Speeds up border processing
HTS Code Structure
- 62 = Chapter (Apparel)
- 6203 = Heading (Men's suits)
- 6203.42 = Subheading (Cotton trousers)
- 6203.42.4011 = Full US HTS code
Common HTS Code Examples
| HTS Code | Product Description |
|---|---|
| 6203.42.40 | Men's cotton trousers |

HTS Code Lookup vs HS Code Lookup
An HS code lookup and an HTS code lookup begin in the same place and finish somewhere different. HS codes are the six digit Harmonized System codes maintained by the World Customs Organization and shared by more than 200 countries. HTS codes are the United States extension of those six digits, running to ten, and they are what US Customs and Border Protection actually assesses duty against.
That means the first six digits of your HTS code are your HS code. If a supplier abroad sends you a six digit number, you are most of the way there, but you still need the remaining four US digits before you can file an entry or calculate a landed cost. The search on this page returns the full ten digit US code, so an HS code lookup and an HTS code lookup are the same search here.
The international HS code. Travels across borders and is usually enough for a commercial invoice or an export declaration outside the United States.
The US HTS code. Required on an entry summary, and the thing that sets your duty rate along with any Section 301 or Section 232 exposure.
Two products sitting under the same six digit heading can carry different rates once the US statistical suffix is applied. Guessing the tail is how importers overpay or get held at the border.
Once you have the ten digit code, the duty calculator applies the current Column 1 rate plus any Section 301, Section 232, Section 338 or antidumping exposure for the country you are importing from. Calculate the duty on your code
Frequently Asked Questions
Yes, code lookup is free. Search current HTS schedule codes or use AI suggestions to narrow a product description. Review the product details before choosing a classification.
Up to 10 Gateway AI classifications a day from one IP address are free, with no sign-up. Answering the questions Gateway AI asks about a product does not use another classification. Gateway Lines customers classify without a limit. Searching the schedule by code or keyword on this page does not use them.
Yes. On the Gateway AI classification page you describe the product in your own words. Gateway AI reads the official text of the tariff headings that could hold it, the Section and Chapter Notes that decide between them and CBP rulings on similar products, and asks when a fact such as fiber content or end use changes the line. It answers with a 10-digit line from the current schedule, the reason at every level and a confidence rating of high, medium or low. It is a planning answer, not a binding ruling.
HTS (Harmonized Tariff Schedule) codes are product classification codes used by US Customs for import duties and taxes. Every product imported into the United States requires an HTS code to determine duty rates, regulatory requirements, and trade program eligibility. Using the correct HTS code ensures smooth customs clearance, accurate duty calculations, and helps avoid delays or penalties at the border.
HS (Harmonized System) codes are the international 6-digit codes used worldwide by over 200 countries. HTS (Harmonized Tariff Schedule) codes are US-specific extensions that add additional digits for more detailed classification. The first 6 digits are the same internationally, but the US adds up to 4 more digits for a total of 10. Our database includes the full 10-digit US HTS codes from the official 2026 USITC schedule.
