HSN Code Finder for India

What is an HSN code?

HSN stands for Harmonised System of Nomenclature, a globally standardised numeric system for classifying traded goods. Developed by the World Customs Organization (WCO), it is used by over 200 countries. In India, HSN codes were adopted under the GST framework and are mandatory on tax invoices to identify goods and their applicable GST rate.

Every physical product you sell — from a bar of soap to a laptop — has an HSN code. The code ties your invoice line item to a specific GST slab (0%, 5%, 12%, 18% or 28%) and ensures your GSTR-1 and e-invoice are correctly classified.

What is a SAC code?

SAC stands for Services Accounting Code. It is India's equivalent of HSN but for services — maintained by the CBIC. SAC codes are 6-digit numbers assigned to every category of taxable service, from restaurant meals (996331) to software development (998314) to gym memberships (999722). If you raise a GST invoice for a service, the SAC code must appear in the same way that HSN does for goods.

How many HSN digits are required?

India's HSN requirement depends on your annual aggregate turnover (AAT) in the previous financial year:

• Up to ₹1.5 crore: No HSN mandatory on B2C invoices; optional on B2B.
• ₹1.5 crore – ₹5 crore: 2-digit HSN on B2B invoices.
• Above ₹5 crore: 4-digit HSN on all invoices (B2B and B2C).
• e-invoicing (above ₹5 crore): 6-digit HSN is required on all e-invoices uploaded to the IRP.
• Export invoices: Always require the full 8-digit HSN code.

Voluntarily using 6 or 8 digits even when not required is always permitted and is best practice for accurate ITC reconciliation.

Understanding the HSN digit structure

An 8-digit HSN code breaks down into four levels:

Start with the broadest 2-digit chapter to locate your product, then drill down to 4 or 6 digits for the precise classification.

How to find the right HSN or SAC code

1. Use the search tool above — type the product or service name, or the first few digits of a code you already know.
2. Verify on the GST portal — visit gst.gov.in → Services → User Services → Search HSN/SAC.
3. Check the Customs Tariff — the CBIC publishes the full tariff schedule with 8-digit codes.
4. Consult your CA — if your product is borderline between two headings, a qualified tax professional can advise on the most appropriate classification.

Using the wrong HSN code can result in an incorrect GST rate being charged, potential scrutiny during audits, and mismatches in your ITC (Input Tax Credit) claim. It is worth taking the time to get it right.

HSN codes and BillRaja

BillRaja is a GST billing app built for Indian small businesses. When you add a product to your product catalogue, you can store its HSN or SAC code once. Every time you create an invoice, BillRaja automatically prints the HSN code in the line-item table — just as required by the GST invoice format rules.

BillRaja also generates an HSN-wise summary section on your GSTR-3B-ready reports, grouping your turnover and taxes by HSN chapter so you can fill in Table 12 of your GSTR-1 return without manually tallying codes. You can generate a GST invoice with HSN codes in seconds, and share it via WhatsApp as a PDF — all from your phone.
