What is an HS code?

The Harmonized System (HS) is the international product-classification standard maintained by the World Customs Organization and used by more than 200 countries. Every product that crosses a border gets an HS code, which determines tariff rates, import/export statistics, and regulatory requirements. Getting the code right matters: it decides what duty you pay and whether your shipment clears customs without delay.

How HS codes are structured

HS codes are hierarchical. Taking 9403.60 (other wooden furniture) as an example:

Digits	Level	Example	Meaning
2	Chapter	94	Furniture; bedding, mattresses; lamps
4	Heading	9403	Other furniture and parts thereof
6	Subheading	9403.60	Other wooden furniture

The 6-digit subheading is harmonized worldwide. Individual countries extend it — the U.S. uses 10-digit HTS numbers for imports and 10-digit Schedule B numbers for exports, both built on the same 6-digit HS root.

Frequently asked questions

What is an HS code?

An HS (Harmonized System) code is a standardized numerical code used by customs authorities worldwide to classify traded products. It is maintained by the World Customs Organization and used by more than 200 countries. Every product crossing a border is assigned one — it determines tariff rates, trade statistics, and regulatory requirements.

How are HS codes structured?

HS codes are hierarchical: the first 2 digits are the chapter (e.g. 94 — furniture), the first 4 digits are the heading (9403 — other furniture and parts), and 6 digits are the subheading (9403.60 — other wooden furniture). The 6-digit level is harmonized internationally; countries extend it further (8–10 digits) for their own tariff schedules.

What is the difference between HS, HTS, and Schedule B codes?

All three share the same first 6 digits. HS is the international 6-digit standard. HTS (Harmonized Tariff Schedule) is the 10-digit U.S. import classification used to determine duty rates. Schedule B is the 10-digit U.S. export classification. If you are importing into the U.S., you file under an HTS number; the 6-digit HS code is its international root.

How do I find the right HS code for my product?

Search by a plain-language product description (e.g. “wooden furniture” or “lithium batteries”) and review the matching subheadings and their chapter context. For a binding classification, consult a licensed customs broker — the legally correct code depends on material, function, and composition.
