What is HSN Code ?
HSN codes help remove confusion in goods classification and simplify domestic and international trade.
India adopted HSN under GST to maintain global uniformity in taxation.
HSN Worldwide
The HSN system is used by more than 200 countries and economies for reasons such as:
- Uniform classification
- Base for their Customs tariffs
- Collection of international trade statistics
Over 98% of the merchandise in international trade is classified in terms of the HSN.
Harmonized System of Nomenclature number for each commodity is accepted by most of the countries. The HSN number remains same for almost all goods. However, HSN number used in some of the countries varies little, based on the nature of goods classified.
HSN in India
India is a member of World Customs Organization(WCO) since 1971. It was originally using 6-digit HSN codes to classify commodities for Customs and Central Excise. Later Customs and Central Excise added two more digits to make the codes more precise, resulting in an 8 digit classification.
HSN Code Structure in India (8 Digits)
- First 2 digits – Chapter Number
- Next 2 digits – Heading
- Next 2 digits – Sub-heading
- Last 2 digits – Tariff Item
