HSN Code Guide for Indian Ecommerce — Stop Penalties
By GrowwwTech··2 min read
What Are HSN Codes and Why They Matter
HSN (Harmonized System of Nomenclature) codes are standardized codes that classify traded products. Every product sold in India needs an HSN code on its GST invoice.
Why getting it wrong is expensive:
Wrong GST rate applied — If your HSN code maps to 18% GST but you’re charging 12%, you owe the difference + interest
Input Tax Credit blocked — Your buyers can’t claim ITC if the HSN code is wrong on your invoice
GST notice — Mismatch triggers automated notices from the GST system
Penalty — Up to ₹50,000 per instance of incorrect HSN reporting
Marketplace listing issues — Amazon and Flipkart increasingly validate HSN codes during listing
How to Find Your Product’s HSN Code
Method 1: GST Portal HSN Search
Go to cbic-gst.gov.in → GST Rate Finder
Enter your product description
Review the results — look for the most specific match (8-digit HSN is most accurate)
Verify the GST rate matches what you’ve been charging
Method 2: Customs Tariff
The Central Board of Indirect Taxes and Customs (CBIC) maintains the complete HSN tariff
Note: GST rates and HSN classifications are updated periodically. Always verify with the latest GST rate schedule.

Common Mistakes
Using generic HSN codes — ‘Articles of apparel’ (Chapter 62) instead of specific ‘Men’s cotton shirts’ (6205). Be as specific as possible.
Same HSN for all variants — A product priced at ₹800 (5% GST) and ₹1,200 (12% GST) need different tax treatment even if they’re the same product.
Not updating after GST Council changes — GST rates change periodically. Review your HSN codes after every GST Council meeting.
Ignoring marketplace validation — Amazon and Flipkart now cross-check HSN codes. Incorrect codes can lead to listing suspension.
