HS code finder
Describe a product in plain words and get the 6-digit HS subheadings that fit it best, from the current US Harmonized Tariff Schedule — each linked to its US duty rates.
How it works
From a description to a code, in plain terms.
- 1
Describe the product
What it is and what it is made of, in your own words. “Kiln-dried white oak lumber” finds more than “wood”. No account, no email.
- 2
Matched to the US tariff schedule
Your description is compared with every 6-digit subheading of the Harmonized Tariff Schedule of the United States, as the U.S. International Trade Commission publishes it. Only codes that exist in the schedule are ever returned.
- 3
A shortlist, most likely first
Up to eight subheadings, each with its heading and chapter, so you can see where it sits in the schedule. When nothing fits well enough, it says so instead of guessing.
- 4
Check the code, then the duty
Open a code's reference page to read every US tariff line and rate beneath it, or take the code straight to the free duty calculator.
Where it stops
What it will not do.
Worth knowing before a code goes on a commercial invoice.
- Suggestions, not a classification. Classifying goods is the importer's responsibility — confirm the code with your licensed customs broker before you file.
- Six digits, not ten. A customs entry needs the destination country's full tariff line (8 or 10 digits in the United States); the finder stops at the internationally shared 6-digit subheading.
- It cannot apply the schedule's section and chapter notes, or know what a short description leaves out — how the product is made, what it is for, what share of it is which material. Those details decide many classifications.
- It does not look up binding rulings, and it does not tell you the duty. The duty calculator does that once you have chosen a code.
- Senda files nothing with US Customs and Border Protection or any other customs authority.
Questions
What people ask us.
What is an HS code?
The Harmonized System is the product nomenclature most countries use to classify traded goods. Its codes are six digits: a 2-digit chapter, a 4-digit heading and a 6-digit subheading. Countries add digits of their own beyond that — the United States uses 8-digit tariff lines plus a 2-digit statistical suffix.
How do I find the HS code for my product?
Start from what the product is and what it is made of, then narrow down from chapter to heading to subheading. The finder does the first pass: describe the product and it lists the subheadings that fit best. Then read each candidate's reference page, check that the heading's wording really covers your goods, and confirm your choice with a licensed customs broker.
Is the HS code the same in every country?
The first six digits are, in every country that uses the Harmonized System. The digits after them are national: a US tariff line and a Korean one for the same goods can differ after the sixth digit, which is why the finder stops at six.
How reliable are the suggestions?
Treat them as a starting point. They are best when the description names both the material and the product, and strongest for wood, paper, and iron and steel goods. When nothing in the schedule fits well enough, the finder says so rather than guessing — and every code it shows is a real subheading of the schedule.
Does it use AI?
No. The free finder matches your description against the tariff schedule on Senda's servers, and nothing you type is sent to an AI model. Inside the Senda workspace, suggestions start from the same search and are then ranked with AI assistance, and every code that ranking returns is checked against the schedule again.
Which version of the tariff schedule does it use?
The Harmonized Tariff Schedule of the United States as published by the U.S. International Trade Commission: currently 2026 HTS Revision 19, released 2026-09-15. Every set of results names the revision it came from.
Is it free? Do I need an account?
It is free and needs no account. If your team classifies new products every week, Senda puts HS suggestions in the same workspace as your orders, shipments and documents — the form under your results reaches a person, not a mailing list.
