HS Code Structure Explained: What Does Each Digit Mean?

Why Is the HS Code So Long?

Most importers see the HS code as just a number. In reality, it's the common language of international trade — used identically by 200+ countries.

The code looks long, but each group of digits has its own meaning. Once you understand the structure, you can read any product's code yourself.

The 4 Parts of an HS Code

Part 1 — Chapter (2 digits)

The first 2 digits indicate the chapter. There are 97 chapters, each covering a broad product category:

Example: Laptop → Chapter 84 (Machinery)

Part 2 — Heading (4 digits)

The next 2 digits identify the heading within the chapter:

84 + 71 = 8471 → Automatic data processing machines (computers)

Part 3 — Subheading (6 digits — International)

The 6-digit code is the international HS code. All 200+ countries share the same system up to this level:

8471 + .30 = 8471.30 → Portable automatic data processing machines (laptops)

This 6-digit code means the same product in every country on earth.

Part 4 — National Split (8–10 digits — country-specific)

In Azerbaijan, the TN XIF code is 10 digits. The last 4 digits are national detail:

8471.30 + .00.10 = 8471.30.00.10 → Exact TN XIF code for Azerbaijan
