Introduction

HSN (Harmonized System of Nomenclature) codes have been an essential element in international trade for decades. However, in India, their significance has grown significantly with the introduction of the Goods and Services Tax (GST) regime. Every business dealing in goods must classify its products under the correct HSN code to ensure seamless GST compliance. A single error in HSN code selection can lead to incorrect tax calculations, compliance issues, and penalties.

Understanding what is HSN code in GST is crucial for every business, whether small or large. With over 5000 commodity categories under the HSN system, businesses must ensure accuracy to avoid unnecessary legal hassles. The HSN code system standardizes the classification of goods, making taxation and trade more systematic and transparent. If a company fails to use the correct HSN code, it may face financial losses due to incorrect tax rates, delayed shipments, or compliance issues.

What is HSN Code in GST?

HSN codes are a globally recognized system of classifying goods systematically. These codes facilitate uniform tax structures and ensure smooth GST compliance. The World Customs Organization (WCO) governs these codes, which consist of 6, 8, or 10-digit numbers depending on the classification depth required by different countries.

How Do HSN Code Rules Work in India?

In India, HSN code rules are structured based on annual turnover:

  • Businesses with turnover up to Rs. 1.5 crore: No HSN code required.
  • Businesses with turnover between Rs. 1.5 crore to Rs. 5 crore: 2-digit HSN code required.
  • Businesses with turnover above Rs. 5 crore: 4-digit HSN code required.
  • For international trade: 8-digit HSN code is mandatory.

The implementation of HSN codes eliminates confusion in GST classification codes and simplifies the GST filing process. Proper classification allows businesses to determine applicable tax rates and comply with GST regulations effectively.

How Does HSN Code Impact the GST Tax Structure?

HSN codes play a significant role in determining tax rates. Different goods fall under specific HSN categories, each attracting a different GST rate. Some examples include:

  • HSN 6403 (Leather Footwear): 12% GST rate.
  • HSN 8703 (Passenger Vehicles): 28% GST rate.
  • HSN 3004 (Pharmaceutical Products): 5% or 12% GST rate, depending on the specific product.

Businesses need to classify their products correctly to avoid incorrect tax payments and compliance risks. Misclassification can result in unnecessary audits and financial losses.

How to Find the Right HSN Code for Your Business?

Finding the correct HSN code for your business is crucial for GST compliance. Here’s how you can determine the appropriate classification:

Step 1: Identify the Product Category

Businesses must thoroughly analyze their products to categorize them correctly. A clear and precise product description helps in selecting the correct HSN code.

Step 2: Refer to the GST Rate Schedule on CBIC Portal

The Central Board of Indirect Taxes and Customs (CBIC) provides an updated list of HSN codes along with applicable GST rates. Reviewing the official list ensures accurate classification and prevents misinterpretation.

Step 3: Use Government-Provided HSN Search Tools

Websites such as the GST Network (GSTN) offer HSN code lookup tools, allowing businesses to search for their product’s classification efficiently.

Step 4: Consult with Tax Professionals

For specific products or unclear classifications, consulting a GST expert or tax professional is advisable. Expert advice helps avoid errors in classification, reducing the risk of tax liabilities.

For example, a company manufacturing leather footwear must classify its products under HSN code 6403 to ensure the correct GST rate applies. Similarly, a business dealing in furniture will fall under HSN 9403, which attracts a 28% GST rate.
