What is HSN Code?

HSN stands for Harmonised System of Nomenclature, an internationally adopted system of names and numbers to classify traded products. Developed by the World Customs Organization (WCO), the HSN code is used by over 200 countries and covers more than 5,000 commodity groups, each identified by a six-digit code arranged in a logical and hierarchical structure. In India, HSN codes are mandatory for GST invoicing and return filing, and the Indian version extends the international six-digit code to eight digits for more granular classification of goods and services.

Under the Goods and Services Tax (GST) regime in India, every taxable supply of goods must be accompanied by the correct HSN code on invoices, e-way bills, and GST returns (GSTR-1, GSTR-3B). The HSN code determines the applicable GST rate for a product, making accurate classification essential for compliance. With the GST 2.0 reforms introduced after the 56th GST Council meeting, the rate structure has been simplified from seven slabs (0%, 0.25%, 3%, 5%, 12%, 18%, 28%) to five slabs (0%, 0.25%, 3%, 5%, 18%, 40%), abolishing the 12% and 28% rates entirely. This makes it even more critical for businesses to identify and apply the correct HSN code to ensure proper tax liability.

HSN Code Structure Explained

The HSN code follows a hierarchical structure where each pair of digits narrows down the classification progressively. Understanding this structure helps businesses quickly locate the correct code for their products. The first two digits identify the chapter, the next two identify the heading, and the final two identify the sub-heading. India further extends the code to eight digits for even more specific product identification, which is mandatory for businesses with annual turnover above Rs. 5 crore.

Why Correct HSN Code Classification Matters

Using the correct HSN code is not merely a compliance formality; it directly impacts the GST rate applied to your supply, the accuracy of your return filings, and your eligibility for input tax credit. A wrong HSN code can lead to underpayment or overpayment of tax, both of which carry penalties under the CGST Act. Under Section 122 of the CGST Act, a penalty of Rs. 10,000 or the tax amount (whichever is higher) can be levied for incorrect classification. Furthermore, mismatched HSN codes between the supplier and recipient in GSTR-2B can cause ITC claims to be rejected, leading to cash flow issues and additional interest liability.

HSN Code vs SAC Code: What is the Difference?

While HSN codes are used for classifying goods (products), SAC (Services Accounting Code) codes are used for classifying services under GST. Both serve the same purpose of standardizing classification, but they apply to different types of supplies. HSN codes follow the international WCO system with chapters 01-97, while SAC codes follow a separate chapter 99 structure specifically designed for services. For example, HSN code 8471 classifies computers (goods), while SAC code 9983 classifies IT/ITeS services. Under GST 2.0, both HSN and SAC codes determine the applicable tax rate, and businesses must use the correct code type depending on whether they are supplying goods or services.
