What is HSN Code ?: HSN stands for Harmonized System of Nomenclature. It’s a system created by the World Customs Organization (WCO) to give every product a unique number. This helps countries all over the world classify goods in the same way.

Think of it like a universal language for products — whether you’re selling rice, clothes, or mobile phones, the HSN code tells exactly what the item is.
How Does the HSN Code Work ?
The code is usually 6 to 8 digits long:
- First 2 digits → Main category (called Chapter)
- Next 2 digits → Sub-category (Heading)
- Next 2 digits → More details (Sub-heading)
- Extra 2 digits (in India) → Even finer details for GST
👉 Example: HSN Code 10063020 = a type of rice (semi-milled or polished).
