What is HSN Code?

HSN (Harmonized System of Nomenclature) is a 6-digit uniform code that classifies 5000+ products and is accepted worldwide. It was developed by the World Customs Organization (WCO) and came into effect in 1988.

In India, HSN codes are used under the Goods and Services Tax (GST) regime to classify goods for taxation purposes. It removes the need to upload the detailed description of the goods. This saves time and makes filing easier and also reduces the chances of errors.

Why is HSN Code Important for GST?

  • Determines the correct GST Rate
  • Mandatory for GSTR-1 Filing
  • Required for E-Way Bill Generation
  • Essential for Input Tax Credit (ITC)
  • Simplifies International Trade

Frequently Asked Questions

What is an HSN code and why is it required on GST invoices?

HSN stands for Harmonised System of Nomenclature — an internationally standardised system for classifying goods developed by the World Customs Organisation. In India, the GST Council mandates HSN codes on invoices to ensure uniform tax treatment and to simplify customs and trade classification. Businesses with annual turnover above ₹5 crore must use 6-digit HSN codes, those between ₹1.5 crore and ₹5 crore use 4-digit codes, and those below ₹1.5 crore are exempt. Incorrect HSN codes can lead to wrong GST rates, mismatches in GSTR filings, and potential notices from the GST department.

What is a SAC code and how is it different from HSN?

SAC stands for Services Accounting Code — the equivalent of HSN codes but for services rather than goods. While HSN codes classify physical products (like rice, medicines, or electronics), SAC codes classify services (like consulting, construction, or repair work). On GST invoices, goods must carry HSN codes and services must carry SAC codes. Both codes are 6 digits long and must appear on B2B invoices. Use the Wiseventory search tool to find both HSN and SAC codes for the products and services you supply.

How do I find the correct HSN code for my product?

The easiest way is to use the Wiseventory HSN code search tool above — enter your product name or description and the tool will suggest the most relevant HSN codes with their corresponding GST rates. You can also consult the official GST Council rate schedule, search the CBIC (Central Board of Indirect Taxes and Customs) website, or check with your chartered accountant for complex or highly regulated product categories. Once confirmed, you can save the HSN code against the product in Wiseventory so it appears automatically on all future invoices.

What happens if I use the wrong HSN code on an invoice?

Using an incorrect HSN code can result in applying the wrong GST rate, which leads to under-collection or over-collection of tax from your customers. Under-collected GST creates a liability for you as the supplier, and over-collected GST that is not deposited to the government is also a violation. Additionally, incorrect HSN codes cause mismatches in GSTR-1 and GSTR-2A reconciliation, which can trigger automated notices from the GST department. Always verify HSN codes for new products before adding them to your invoice template.

Can I save HSN codes in Wiseventory for my products?

Yes. In the Wiseventory billing platform, each product in your catalogue can have its HSN code saved permanently. Once set, the HSN code appears automatically on every invoice for that product — you never need to enter it manually again. When GST rates or HSN code classifications change (which the government updates periodically), you can update the code for a product in one place and all future invoices will reflect the change automatically.
