What Is HSN Code

What is HSN Code?

The Harmonized System of Nomenclature (HSN) is an internationally accepted six-digit system developed by the World Customs Organization (WCO) to classify goods in a structured manner. It helps businesses and governments track imports, exports, and domestic trade more efficiently.

India, like many other countries, uses HSN codes for taxation purposes. Under the GST system, HSN codes are mandatory for businesses to correctly classify their goods and determine the applicable GST rate.
 

Why is HSN Code Important in India?

1. Standardized Taxation – HSN codes help businesses apply the correct GST rate to different goods, avoiding tax confusion.
2. Smooth International Trade – Since HSN is globally accepted, it simplifies import and export processes.
3. Reduced Tax Evasion – Accurate classification of goods prevents tax manipulation and ensures compliance.
4. Efficient Invoicing – Using HSN codes on invoices ensures accuracy in GST returns and smooth processing of input tax credit (ITC).
5. Automated Compliance – The Indian GST system auto-detects applicable GST rates based on HSN codes, making filing returns easier.
    

How Does HSN Code Work in India?

In India, the HSN system follows a structured approach:

• HSN Code Structure:
  • 2-digit HSN – Used for a broad category of goods.
  • 4-digit HSN – Used for specific product categories.
  • 6-digit HSN – Internationally accepted classification for global trade.
  • 8-digit HSN – Further classification adopted in India for greater accuracy.
     

For example:

Businesses must use HSN codes on GST invoices, E-way bills, and GST returns to comply with taxation laws.

HSN Code Applicability Under GST

The requirement to mention HSN codes depends on a business’s annual turnover:

Note: For small businesses with a turnover of less than ₹5 crore, HSN codes are optional for B2C (Business to Customer) transactions. Also, 8-digit HSN is only required in customs filings, not for GST returns.
 

How to Find the HSN Code for Your Product?

You can find your product’s HSN code using:

1. GST Portal – The government provides a search tool on the GST website to find the applicable HSN code.
2. HSN Code Books – Businesses can refer to the official WCO HSN classification or GST council’s HSN handbook.
3. Trade Associations – Industry bodies and professional consultants can help businesses find the correct HSN code.

To identify an HSN code, follow these steps:

• Identify the type of goods your business deals in.
• Search for the broad category under the WCO HSN system.
• Narrow down the classification using GST rate charts.

For instance, if you sell electronic goods, your HSN code would fall under Chapter 85 (Electrical machinery and equipment).
 

HSN Code vs SAC Code

While HSN codes classify goods, the SAC (Services Accounting Code) is used to classify services under GST.
