What is HSN / SAC Code under GST?

By Sakshi Shah on June 26, 2019

There are innumerous variety of goods and services. Applying a common rate of tax to all goods and services is not possible. Thus, they are classified into groups and sub-groups and a specific GST rate is applied to a specific sub-group. The most scientific way of classifying goods is on the basis of HSN while classifying services is on the basis of SAC.

HSN means the Harmonized System of Nomenclature code used for classifying goods under GST. The HSN classification is used in Customs, Central Excise and Foreign Trade Policy. The use of HSN codes is to make GST systematic and globally accepted.

However, there is no international classification of services similar to HSN for goods. They are classified on the basis of SAC. SAC means Service Accounting Code used for classifying services under GST.

How many digits of HSN or SAC should I mention in my invoice?

Annual Turnover in previous financial yearHSN Digits to be shown in Invoice & Return
T/O <= 1.5 CrNIL
1.5 Cr < T/O <= 5 Cr2
T/O > 5 Cr4

In the case of Imports/ Exports, HSN codes of 8 digits shall be compulsory since GST needs to be compatible with international standards and practices.

Where should I mention HSN / SAC Code?

HSN for goods and SAC for services should be mentioned by the taxpayer at the following instances:

1. GST Registration
Under GST, every business must declare the type of goods or services they are dealing into. Thus, it is important to mention the correct HSN/SAC Code at the time of enrollment or registration.

2. GST Rate
