Check an HS code

Paste a code from a supplier, a shipping form or an AI chat. We look it up in the current US tariff schedule and show what it really covers.

Source: USITC Harmonized Tariff Schedule, Revision 21 (2026), checked 2026-10-27. The first six digits are the same in every country that uses the HS; digits 7 to 10 are national, so a valid US code may not exist in the UK or EU.

Why codes from AI chats need checking

Chat assistants write codes that look right but often are not. In our own test on 49 recent CBP rulings, a general AI model given only the product name picked the right six-digit subheading 43% of the time.

A code that exists is not proof it fits your goods. Read the official text below the result and compare it with your product, or use one of our product guides.
