HSN is an internal system of naming goods. HSN is assigned to goods by organizing them in a hierarchical manner and is 8 digits long. However, a good can be identified broadly by using no less than 2 digits, and very specifically by using all the 8 digits. Depending on the turnover or nature of sale, a business might be required to quote a 2-digit HSN, a 4-digit HSN or an 8-digit HSN (mandatory for exports).
- A business whose turnover is less than INR 1.5 crore need not quote HSN in the invoice
- A business with turnover between INR 1.5 crore and INR 5 crore will need to quote a 2-digit HSN
- A business with turnover equal to or greater than INR 5 crore will need to quote a 4-digit HSN
- All exports will need to quote 8-digit HSN in the invoice
- Small businesses under composition scheme will not be required to mention HSN codes in their invoices
- At the time of registration/migration, the business taxpayer will be required to mention HSN code of the goods he deals with during registration
