How to find your HS code for export from India

Written for Indian MSME manufacturers and exporters preparing their first (or next) export shipment.

Your HS code is the Harmonized System number that customs authorities in more than 200 countries use to classify your product. The fastest way to find it: open one of your own GST invoices and read the HSN column, because India's GST HSN codes and export HS codes are the same classification family. That gives you the first 4 or 6 digits. For export paperwork you need the full 8-digit ITC-HS code, which you can confirm free on the DGFT ITC-HS schedule, the CBIC Customs Tariff, or with your customs broker (CHA). Ten careful minutes here pay for themselves: the exact code decides the import duty your buyer pays, your FTA or CEPA rate, the compliance rules (NTMs) your product must meet, and your RoDTEP claim, and it appears on every export document from the shipping bill to the Bill of Lading. Below, a worked example walks a cotton T-shirt from chapter 61 all the way to its full 8-digit code, 61091000.

What is an HS code?

The Harmonized System (HS) is the product classification maintained by the World Customs Organization (WCO). It sorts everything traded across borders into over 5,000 six-digit product groups across 97 chapters, and more than 200 countries and economies run their customs tariffs on it. Every duty rate, trade statistic, and preferential agreement you will ever deal with as an exporter keys off this number.

HS vs HSN vs ITC-HS: three names, one system

Indian MSMEs meet the same code under three names, and the confusion ends once you see the depths. HS is the global 6-digit standard. HSN is what India's GST system calls the same codes, which is why your GST invoices already carry a 4, 6, or 8 digit HSN column. ITC-HS (Indian Trade Classification based on the Harmonized System) is the full 8-digit version maintained by the DGFT, and it is the code your shipping bill, export policy status, and RoDTEP claim run on. The first 6 digits are identical in all three.

How the code is built: a cotton T-shirt, worked end to end

Take a knitted cotton T-shirt, one of India's flagship apparel exports (see the cotton T-shirt buyer page). Its code assembles digit pair by digit pair:

61

Chapter

Knitted or crocheted apparel. The first 2 digits place your product in 1 of 97 chapters.

6109

Heading

T-shirts, singlets, and other vests. The 4-digit heading names the product family.

6109.10

Subheading

Of cotton. The 6-digit subheading is the level harmonized across the world.

61091000

ITC-HS tariff item

India's full 8-digit export line, the one your shipping bill and RoDTEP claim use.

5 free ways to find your exact code

1. Your own GST invoices

How: Open any sales invoice or GSTR filing and read the HSN column. India's GST HSN codes are the same classification system, so this hands you the first 4 or 6 digits in under a minute.

Worth knowing: Fastest starting point, but confirm the full 8-digit line before you quote an overseas buyer.

2. The DGFT ITC-HS schedule

How: The DGFT website's ITC-HS search lets you look up the 8-digit export classification by product description. It also shows the export policy status for that line (free, restricted, or prohibited).

Worth knowing: This is the official source for the 8-digit code Indian export documents run on.

3. The CBIC Customs Tariff

How: CBIC publishes the full Customs Tariff with chapter notes. The notes are what settle borderline cases, like whether a product classifies by its material or by its function.

Worth knowing: Read the chapter notes whenever two headings both look plausible.

4. The ICEGATE duty lookup

How: ICEGATE's tariff and duty calculator lets you search a code and see the duty picture on that tariff line, a quick way to sanity-check that the line you picked behaves the way you expect.

Worth knowing: Use it as a duty-rate cross-check after you have a candidate code.

5. Your CHA or freight forwarder

How: A customs broker (CHA) confirms the exact 8-digit line customs will accept for your product, based on what clears in practice. Ask them to confirm it in writing before your first shipment.

Worth knowing: The cheapest insurance against a classification dispute at the port.

Why the exact 8-digit line pays

Almost every commercial outcome in exporting, and every export document, keys off the classification:

  • Import duty (tariff): the duty your buyer pays at destination is set per tariff line.
  • FTA and CEPA rates: preferential claims, like the India-UAE CEPA advantage many Indian products enjoy, are checked against the exact line plus rules of origin, and the certificate of origin is issued against that line.
  • RoDTEP: incentive rates are notified per 8-digit ITC-HS line, so a wrong code means a wrong or denied claim.
  • NTM compliance: non-tariff measures in the destination market (product certifications, labeling, testing, sanitary and phytosanitary rules) are keyed to the HS code, so the code decides which compliance checklist applies to your shipment.
  • Shipping bill: filed with the 8-digit ITC-HS code; this is the document your RoDTEP claim flows from.
  • Bill of Lading and commercial invoice: carry the same code; a mismatch across your documents is what triggers customs queries and clearance delays on either side.

The two most common mistakes: quoting only 6 digits where documents need 8, and classifying a composite product by its material when the chapter notes classify it by function (or the reverse).

From code to buyers: what the HS code unlocks

The code itself is paperwork. What it unlocks is the research: which markets import your product at growing, steady volumes, what duty your line faces in each, which compliance requirements (NTMs) apply, and where a trade agreement gives Indian exporters an edge. That is exactly where diipl starts. We read the demand and duty picture for your HS code across markets, run precision outreach to the importers actively sourcing it, and verify every buyer on budget, authority, need, and timeline before you speak.

Frequently asked

What is the difference between HS code, HSN code, and ITC-HS code?

They are the same classification system at three depths. The HS code is the 6-digit Harmonized System maintained by the World Customs Organization and shared by more than 200 countries. HSN is the name India's GST system uses for the same codes, which is why your GST invoices already carry a 4, 6, or 8 digit HSN. ITC-HS is India's full 8-digit trade classification, maintained by the DGFT, and it is the code your export documents, shipping bill, and RoDTEP claim run on. The first 6 digits are identical across all three.

Is my HS code the same in every country?

The first 6 digits are harmonized worldwide, so a cotton T-shirt is 6109.10 in India, the UAE, and the USA alike. Beyond 6 digits each country extends the code its own way: India uses 8-digit ITC-HS lines, the USA uses 10-digit HTS lines, the EU uses 8-digit CN lines. Practical rule: quote the 6-digit code when talking to overseas buyers, and use the full 8-digit ITC-HS code on your Indian export paperwork.

Where can I find my HS code for free?

Five free routes: the HSN column on your own GST invoices, the DGFT website's ITC-HS search, the CBIC Customs Tariff with its chapter notes, the ICEGATE duty lookup to cross-check a candidate line, and your customs broker (CHA). diipl's find-buyers pages also list the HS codes for common Indian export products, and the free Custom Product Report confirms the classification for your specific product as part of the walkthrough.

What happens if I use the wrong HS code?

Five things go wrong. Your buyer can be charged the wrong import duty at destination, which sours the deal. Your shipment can lose a preferential FTA or CEPA rate it was entitled to, because preferential claims are checked against the exact tariff line. You can end up meeting the wrong compliance checklist, since destination-market non-tariff measures (certifications, labeling, testing) are keyed to the HS code. Your RoDTEP incentive can be wrong or denied, since rates are notified per 8-digit ITC-HS line. And a code mismatch across your shipping bill, Bill of Lading, and commercial invoice invites customs queries and clearance delays. Ten careful minutes on classification protect all five.

How does diipl use my HS code?

The HS code is where the research starts. diipl uses it to read which markets import your product at growing, steady volumes, what duty your product faces in each market, and where a trade agreement gives Indian exporters a preferential edge. That analysis becomes your free Custom Product Report, a 30 to 45 minute walkthrough with a research analyst, and it is the same research that decides where we generate verified buyers for you.
