How to find the HS code for your products

Describe the product in a few words or type a code you already have. The free HS code finder suggests codes from the EU Combined Nomenclature 2026 or the US HTS, and every code links to its place in the HS code directory. Treat the result as a starting point and check it with the steps below.

The Harmonized System (HS) is maintained by the World Customs Organization and used by customs authorities worldwide. It has 97 chapters, with chapter 77 reserved for future use, and its codes have 6 digits. Up to those 6 digits a product has the same code in every country that uses the HS.

Each country adds digits for its own duties and statistics. The EU Combined Nomenclature (CN) has 8 digits and is republished every year; the 2026 edition is Regulation (EU) 2025/1926 and has 16,728 codes in the edition WISEPIM uses. TARIC, the EU's integrated tariff, adds two more digits for measures such as duty suspensions, quotas and anti-dumping duties. The US Harmonized Tariff Schedule (HTS) has 10 digits: an 8-digit tariff line plus a 2-digit statistical suffix. HTS 2026 Revision 21 has 38,181 codes in the edition WISEPIM uses.

Every level narrows the one above it. Here is a knitted cotton T-shirt in the EU Combined Nomenclature 2026, with the official line text of each level.

Customs classifies with the General Interpretative Rules (GRI) printed at the start of the nomenclature. Rule 1 is the one that decides most cases: classification follows the terms of the headings and the section and chapter notes, and the titles of sections and chapters are for reference only. A heading that sounds right but is excluded by a chapter note is the wrong heading.

This guide is not legal advice. A code from a finder, a supplier or this page is a suggestion, not a binding classification. Check it with a customs broker or the customs authority, or apply for a Binding Tariff Information (BTI) decision.

A BTI is a classification decision for one specific product. In the EU it is free, valid for three years and binding on the customs authorities of every member state and on you as the holder. You apply electronically and can search the BTIs already issued, without confidential details, in the EBTI database. In the US, Customs and Border Protection issues binding rulings, which you can search in CROSS.

Customs declarations need a commodity code for every product, so marketplaces that ship across borders, Amazon among them, and courier and postal services ask sellers for HS codes. The exact field name and the number of digits differ per channel and destination, so check each channel's own documentation.

A practical rule: store the 6-digit HS code as the shared minimum, and add the 8-digit CN or 10-digit HTS code for the markets you ship to. A wrong code can mean the wrong duty, a held shipment or a correction afterwards.

Put the code on the product, not on each order or shipment, so every channel and every declaration uses the same value. Variants usually share a code, but a change of material can change it, as the cotton and man-made fibre T-shirts above show.
