Places where HSN Code finds its importance in GST Law


The GST roll-out on 1st July 2017 has paved the way for realization of the goal of One Nation – One Tax – One Market. GST is expected to benefit Indian economy overall with most tax compliant businesses getting favourably impacted. It should in time reduce the cost of goods & services, giving a boost to the export of products and services. It would also foster ‘Make in India’ initiative. GST promotes the concept of common market with common tax rates & procedures and removal of economic barriers thus improving ease of doing business.


In this article we would learn as what does HSN Code mean and how much importance it finds in GST law. The word Nomenclature which is suffixed to the term “HSN” has in it itself an hidden meaning to understand the Harmonised System of Nomenclature (HSN) and for what it stands for Harmonized System of Nomenclature (HSN)  which was developed by the World Customs Organization (WCO) with the vision of classifying goods all over the World in a systematic manner. Nomenclature here means devising or choosing of names for things. HSN contains of a six digit uniform code that classifies 5,000+ products and which is accepted worldwide.

Chapter III : Levy and Collection of Taxes


  • In determining Rate and Value of Tax : Here the GST law says that the tax rate will be the rate as specified in the notification that would be issued in this regard, subject to a maximum of 28%. The rates would be determined based on the recommendation of the Council and the rate of tax so notified will apply on the value of supplies as determined under the Act . And in order to determine such applicable tax, rate determination has to be made in the following manner:


(a) Identify HSN of the product or service and applicable rate of Tax as per rate notification

(b) Once classification is arrived at, look for as to whether such product falls into any specific exemption or not

(c) One also need to look for special transactions like zero rated supplies (exports and Supply to SEZ)

(d) If (b) and (c) are not available, tax at determined rate shall be arrived by multiplying value with such rate.


It is thereby clear that in order to determine the applicable Tax rate for product HSN Code plays an pivotal role as it helps on classifying the products for which tax rate is to be determined. This takes us as how HSN Codes helps in classifying a product :This is also covered in GST Act under the chapter Levy and Collection of Taxes covered by the heading classification of Goods or Services. Let us take a visit of the same.


  • Classification of Goods or Services : In this section law speaks that in order to apply a particular rate of tax, a taxable person need to determine the classification of his supply as to whether his supply constitute supply involving supply of goods and or services. Once the same is determined, further classification in terms of HSN in case of goods and SAC in terms of service is to be made by the assessee so as to arrive at the rate of tax at which he is required to pay tax. At the outset, it is important to note that HSN for goods are contained in Chapters from 1 to 98 and HSN for Services are contained in Chapter 99. Since Classification of Goods is older and is based on knowledge gathered from precedents on HSN classification, we shall discuss the steps for classification of goods.





The steps for determination of proper classification is as under:


Step 1 : It is important to note that classification of each product supplied has to made separately if supply of such product is independent. This shall include all by products, scraps etc.

Step 2 : Identify the description and nature of the goods being supplied. One must confirm that the product is also similarly or more specifically covered in the Customs Tariff and HSN 2017. The Section Notes and Chapter Notes to the Schedule to be read.

Step 3 : If there is ambiguity, first reference shall be made to the Rules for interpretation of the Customs Tariff.

  1. As per the Rules, first step to be applied is to find the trade understanding of the terms used in the Schedule, if the meaning or description of goods is not clear.
  2. If the trade understanding is not available, the next step is to refer to the technical or scientific meaning of the term. If the tariff headings have technical or scientific meanings, then that has to be ascertained first before the test of Trade understanding.
  3. If none of the above are available reference may be had to the dictionary meaning or ISI specifications. Evidence may be gathered on end use or predominant use.

Step 4 : In case of the unfinished or incomplete goods, if the unfinished product bears the essential characteristics of the finished product, its classification shall be same as that of finished product.

Step 5 : If the classification is not ascertained as per above point, one has to look for the nature of product which is more specific.

Step 6 : If the classification is still not determinable, one has to look for the ingredient which gives the article its essential characteristics.

Step 7 : If still ambiguity persist, one shall resort to trade understanding of the product and in absence of such trade understanding, we shall refer to the technical or scientific meaning. However if the tariff headings have technical or scientific meanings, then that has to be ascertained first before the test of trade understanding. If none of the above is

available, reference may be made to the dictionary meaning or ISI specifications.


Also in Chapter No. VII of GST Law which speaks about invoicing rules “ Tax Invoice, Credit and Debit Notes” we have some mention of HSN Codes. Let us now read the part related to HSN Code and know how much is HSN Code important when you decide to prepare or make an invoice.
