HSN (Harmonised System of Nomenclature) is the code that classifies goods for GST. Services use a SAC code instead. The code decides the GST rate for the item.
How many digits do you need?
| Annual turnover | Digits | On which invoices |
|---|---|---|
| Up to ₹5 crore | 4 | B2B invoices (optional on B2C) |
| Above ₹5 crore | 6 | All invoices |
