HSN, SAC and your GST rate

Every item on a GST invoice carries an HSN (goods) or SAC (services) code, and that code fixes the GST rate. Getting it wrong means the wrong tax on your invoice and mismatches at GSTR-1. Search above to confirm the code and rate before you bill — or browse GST rates by product →

Frequently asked

What is an HSN code?

HSN (Harmonised System of Nomenclature) is a global system for classifying goods. In India, HSN codes drive the GST rate and must be shown on GST invoices. Services use SAC (Service Accounting Codes) instead.

How many HSN digits do I need on my invoice?

It depends on turnover: businesses with aggregate turnover up to ₹5 crore need 4 digits for B2B (optional for B2C); above ₹5 crore need 6 digits. Always show the code that matches your item.

How do I find the GST rate for a product?

Search the product name or its HSN code above. The tool returns the matching code and the standard GST rate (0/5/12/18/28%). For conditional or notified rates, verify against the latest CBIC notification.

What is the difference between HSN and SAC?

HSN codes classify goods; SAC codes classify services. Both determine the applicable GST rate and are required on invoices. This tool covers both — search a product or a service.
