What is HSN Code?

HSN, or Harmonized System of Nomenclature, is a global standard for categorizing goods in a systematic manner. It came into effect from the year 1988 and was developed by the World Customs Organization (WCO). 


Further, HSN is a 6-digit code that is used to classify more than 5,000 products and is accepted worldwide. 

How does the the HSN Code work?

The HSN is a standardized system used globally to name and classify products traded internationally. Adopted by over 200 countries, it covers nearly 98% of all merchandise traded worldwide.


The HSN code plays an important role in taxation, particularly under the GST (Goods and Services Tax) regime, as it identifies a specific product or category. 


This system operates under a set of rules that outline the principles and methods of classification. These rules maintain uniformity and accuracy in applying HSN codes and resolve any discrepancies that may arise. 


These codes also serve valuable business purposes, like: 

  • Determine eligibility and benefits under trade agreements

  • Ease the trade statistics collection and analysis. 

  • Provides a common language for product classification. 

Understanding the HSN Code

Generally, HSN codes contain:

  • 21 sections

  • 99 chapters

  • 1244 headings

  • 5224 subheadings


The HSN code follows a hierarchical structure:

  • Each chapter is identified by a two-digit HSN number.


  • These two-digit numbers are then further classified into four-digit HSN codes.


  • Finally, the four-digit HSN codes are subdivided into six-digit HSN codes, offering the most detailed classification level.


Later on, the Customs and Central Excise authorities added two more digits to the 6 digit HSN code to make it more precise. This resulted in a 8-digit classification and was done to align with the GST regime. 


Let’s understand this with an example. 


As you can see in the image below will be 10.06.30


The first two digits indicate the chapter, i.e., 10, heading 06, and subheading 30.

The HSN (Harmonized System of Nomenclature) code is a classification system used globally to organize and categorize various products. Here’s its importance. 

  • It provides a systematic and logical method for classifying goods, considering factors like material, function, and origin. 


  • These codes ensure uniform classification of goods across different countries. This ultimately minimizes the chances of disputes and errors in trade transactions.


  • With that being said above, 98% of international trade stock is classified in terms of HSN, which further proves it as best form of international classification. 


  • As new products emerge or old ones become less common, the HSN system can be updated to reflect these changes. 


  • Using the same codes worldwide ensures consistency and fairness in trade.
