| Heading | Four digits, for example 61.09 |
| Subheading | Six digits, the international code |
| Chapter notes | Legally binding definitions and exclusions |
| Typical split | Chapters 1–24 are largely agricultural; 25–97 are industrial and manufactured goods |
| Official source | WCO HS nomenclature and explanatory notes |
Read the notes before the heading
A heading that sounds right can be excluded by a chapter note. A product described as a garment may be excluded because it is knitted in a particular way, or a food preparation may fall outside a chapter because of its ingredients. The notes are legal text, not commentary.
Start with the section and chapter notes, then read the heading and subheading text. If the product is mentioned explicitly, the analysis usually stops there unless a note says otherwise.
The same product can move chapters after processing
Raw material, semi-finished goods and finished goods often sit in different chapters. That matters for origin rules: a change of chapter or heading may be exactly what qualifies a product under a trade agreement.
When a supplier changes a material or a process, re-check the chapter, not just the final description.
Frequently asked questions
What is chapter 77 used for?
It is reserved for future use in the HS and is not an active product chapter.
Do chapter notes override the heading text?
The notes are legally binding and can define, include or exclude goods. Read them before deciding on a heading.
