What is an HSN Code?
An HSN code (Harmonized System of Nomenclature) is an internationally standardised numeric system to classify traded products. Indian customs extend it to an 8-digit ITC-HS code for more precise classification, taxation and compliance.
- First 2 digits: Chapter (e.g. 29)
- Digits 3–4: Heading
- Digits 5–6: Subheading (WCO-aligned)
- Last 2 digits: Indian ITC extension for added granularity
Why is the right HSN code important?
- Ensures correct calculation of customs duties and taxes.
- Required for shipping bills, bills of entry, GST filings and FTA certificates of origin.
- Helps avoid clearance delays, penalties or reclassification disputes.
