What is an HSN code, and how do you find yours?
For importers and exporters6 min readUpdated
The short answer
An HSN code is the Harmonised System of Nomenclature number that classifies a product for customs. The first 6 digits are common worldwide, and India's customs tariff extends them to 8. The code decides the duty rate, import and export policy and which compliance rules apply, so getting it right before you order matters.
Key takeaways
- HSN is a product-classification system: chapter, heading, subheading, then India's tariff item.
- Classification follows what the product is, how it is made and what it does, not its trade name.
- Chapter and section notes can move a product to a different heading, so read them.
- Duty, import and export policy and compliance all key off the code.
How an HSN code is built
The Harmonised System is run by the World Customs Organization and used by over 200 countries. It groups goods into sections and 97 chapters, each divided into headings and subheadings. The first 6 digits mean the same everywhere. India adds two more digits for its own tariff item, which is why Indian import codes have 8 digits.
| Digits | Level | Example meaning |
|---|---|---|
| 09 | Chapter | Coffee, tea, maté and spices |
| 0902 | Heading | Tea, whether or not flavoured |
| 0902 30 | Subheading | Black (fermented) and partly fermented tea in small immediate packings |
| 0902 30 •• | India tariff item | Two more digits, set by India's tariff for national detail |

Why the code matters
- Duty. BCD, SWS and IGST rates are set against the tariff item.
- Policy. Import and export policy (Free, Restricted, Prohibited, or State Trading) is set by code.
- Compliance. BIS, FSSAI, CDSCO, WPC and similar requirements attach to product categories identified by code.
- Incentives. RoDTEP and duty drawback rates are defined per tariff item.
- Documents. Bills of Entry and Shipping Bills carry the code, and mismatches cause queries and delays.
How to find the right code
- 1
Describe the product precisely
Write down what it is made of, what it does, how it is used and how it is sold (single, set, bulk). Marketing names don't classify goods; material, function and form do.
- 2
Find the chapter
Match the product to the chapter that covers it, using the section and chapter titles as a guide.
- 3
Read the notes
Section and chapter notes say what a chapter includes and excludes. They override how a product 'feels' it should be classified.
- 4
Narrow to heading, subheading and tariff item
Move down the levels, applying the General Rules of Interpretation when two headings seem to fit. The most specific description generally wins.
- 5
Check precedent and confirm
Look at advance rulings for similar goods if they exist, and have your customs house agent confirm before you file.
Common classification mistakes
- Classifying by name instead of composition or function.
- Ignoring what the product is essentially made of when it combines materials.
- Treating parts and accessories like the finished machine, when the chapter notes classify them separately.
- Copying a code from a supplier's invoice without checking it against the Indian tariff.
- Assuming the GST invoice code is the customs code. GST has its own rules for how many digits an invoice needs, based on turnover, but customs classification is the 8-digit tariff item.
The final classification is made by the proper officer at assessment. A good internal answer helps you plan and avoids surprises, but it is not a binding ruling.
