The HSN Code Lookup lets you search common Harmonised System of Nomenclature codes used in Indian trade and GST filings. Type either a description or a partial code, and the tool returns the matching heading along with an indicative GST rate.
HSN classification is one of the most important — and most often mis-handled — parts of both indirect taxation and customs. Getting it right ensures the correct GST rate, the correct import duty and a smooth reconciliation of GSTR-1, GSTR-3B and e-way bills.
What is an HSN code?
The Harmonised System of Nomenclature is a globally standardised 6-digit product classification system developed by the World Customs Organization (WCO). More than 200 countries use it to classify traded goods for customs duty, statistics and trade agreements.
India extends the international 6-digit code to 8 digits under the Customs Tariff and, for GST purposes, requires either 4-, 6- or 8-digit HSN reporting on invoices depending on the taxpayer’s aggregate turnover.
- First 2 digits = Chapter (e.g. 84 for machinery and mechanical appliances)
- Next 2 digits = Heading (e.g. 8471 for automatic data processing machines)
- Next 2 digits = Sub-heading (international 6-digit level)
- Last 2 digits = Tariff item (India-specific extension for the Customs Tariff)
HSN reporting requirements under GST
Turnover-based thresholds
- Aggregate turnover up to ₹5 crore in the previous financial year — 4-digit HSN mandatory for B2B invoices; optional for B2C
- Aggregate turnover above ₹5 crore — 6-digit HSN mandatory for both B2B and B2C
- For exports and imports — 8-digit HSN is mandatory irrespective of turnover
Why correct HSN matters
- It fixes the applicable GST rate and any compensation cess
- It determines the eligibility of concessional rates or exemptions
- A mismatch triggers ITC denial and possible interest and penalty
- It is validated by the e-invoice IRP and by the e-way bill portal
How to use the HSN Lookup
- Step 1Enter a partial code (e.g. 8471) or a keyword from the product description (e.g. "cotton", "footwear", "computer").
- Step 2Scan the returned list — the first column shows the code, the second the WCO description, the third the indicative GST rate.
- Step 3Confirm the exact 8-digit sub-heading with the CBIC tariff or the CBIC portal before applying it on a live invoice.
Tips to classify a product correctly
- Read the section notes and chapter notes — they contain binding classification rules
- Apply the General Rules of Interpretation (GRI) in the correct hierarchical order
- Prefer the heading that gives the most specific description over the general one
- For mixed or composite goods, classify by the material or component that gives the essential character
- When two headings are equally applicable, take the one occurring last in numerical order
