How to Find HSN Code for Your Product India — Complete 2026 Guide

Every product you sell in India has an HSN code. Finding the right one is both a legal obligation and a financial necessity.

Whether you are a new business owner setting up your first GST invoice, an established trader adding a new product line, an accountant verifying your client's product classifications, or a manufacturer registering for GST and needing to classify your entire product range — the question "how do I find the HSN code for this product?" comes up constantly in Indian business.

And getting the answer right matters enormously.

The correct HSN code on your invoice determines the correct GST rate that applies to your product. It determines the GSTR-1 HSN summary that your return must include. It determines whether your e-invoice (IRN) is accepted by the Invoice Registration Portal. It determines whether your buyers can correctly claim ITC based on your invoices. A wrong HSN code can mean charging the wrong GST rate, creating compliance issues, triggering notices from tax authorities, and damaging your buyers' ITC claims.

Yet HSN code classification is not always straightforward. With over 5,000 product codes at the 8-digit level — organized in 99 chapters, hundreds of headings, and thousands of subheadings — finding the precise correct code for a specific product requires a structured approach, the right resources, and often some expert judgment.

This comprehensive guide walks you through every method for finding the correct HSN code for your products in India — from the free online tools to the structured classification methodology to ERP Group's integrated HSN management platform.

Why HSN Code Classification Matters

The Business and Compliance Impact of Correct HSN Codes

Determines Your GST Rate — The Most Important Impact

The GST rate for any product in India is determined by its HSN classification. The rate schedule (GST Rate Notification 01/2017-Central Tax (Rate) and subsequent amendments) assigns GST rates at the HSN code level.

Example of rate impact:

• Cotton fabric (HSN 5208): 5% GST
• Velvet fabric (HSN 5801): 12% GST
• Polyester filament yarn (HSN 5402): 18% GST

Three textile products — three different HSN codes — three different GST rates. A cloth merchant who classifies velvet fabric under 5208 (cotton fabric rate) and bills at 5% instead of 12% is undercharging GST — creating a liability for themselves.

For cloth merchants and textile traders, read our guide on POS software for cloth merchants India.

Mandatory Invoice Compliance

HSN codes are mandatory on GST tax invoices:

• Businesses above ₹5 crore: 6-digit HSN minimum
• Businesses up to ₹5 crore: 4-digit HSN minimum
• E-invoice (IRN): 6-digit HSN required in IRP JSON payload

Missing or incorrect HSN codes make invoices non-compliant — and for e-invoices, invalid HSN codes cause IRN generation failure.

GSTR-1 Table 12 Compliance

GSTR-1 requires an HSN-wise summary (Table 12) of all outward supplies — aggregated by HSN code with total taxable value and GST amounts. Incorrect HSN codes in invoices mean incorrect Table 12 reporting.

Buyer ITC Claims

Your buyer claims Input Tax Credit based on your invoice. If your HSN code is wrong, it creates potential ITC complications — your buyer may face scrutiny for ITC claimed on invoices with inconsistent HSN classification.

Income Tax and Customs Cross-Reference

Income Tax authorities cross-reference GSTR-1 HSN turnover with income tax returns. Customs authorities reference HSN codes for import/export classification. Consistent, correct HSN coding creates a defensible audit trail across all regulatory frameworks.

Understanding the HSN Code Structure

The Architecture You Must Know Before Searching

Understanding HSN code structure makes the search process far more logical and successful.

The Four-Level Hierarchy

Level 1 — Section (21 sections, no numeric code):
HSN organizes all products into 21 sections — broad groupings like "Live Animals and Animal Products" (Section I), "Textile and Textile Articles" (Section XI), "Machinery and Mechanical Appliances" (Section XVI).

Level 2 — Chapter (2 digits, 99 chapters):
Each section contains chapters. Chapter numbers are the first two digits of every HSN code:

• Chapter 10: Cereals
• Chapter 52: Cotton
• Chapter 84: Nuclear reactors, boilers, machinery
• Chapter 87: Vehicles

Level 3 — Heading (4 digits):
Each chapter breaks into headings. The first four digits identify the heading:

• 1001: Wheat and meslin
• 5208: Woven cotton fabrics (≥85% cotton, ≤200g/m²)
• 8471: Automatic data processing machines (computers)

Level 4 — Subheading and Tariff Item (6 or 8 digits):
Headings break into subheadings (6 digits) and India-specific tariff items (8 digits):

• 100110: Durum wheat (variety-specific)
• 520811: Plain weave, ≤100g/m², unbleached (specific fabric type)

The 99 Prefix Rule for Services

All SAC codes (for services) begin with "99" — this distinguishes them from HSN codes (for goods). When searching for a product (good), ensure you are not selecting a "99-series" code.

Exempt vs Taxable at the HSN Level

Some products are exempt from GST at specific HSN codes — like fresh vegetables (HSN 0701-0714), raw grains (HSN 1001-1008), raw cotton (HSN 5201-5202). Others are taxable. The GST rate notification references specific HSN codes for exemptions. Understanding this exemption-at-HSN-level concept is critical for correct classification.

Method 1 — Using ERP Group's Free HSN/SAC Finder

The Fastest and Most User-Friendly Method

What ERP Group's HSN/SAC Finder Provides

ERP Group's Free HSN/SAC Finder → is a searchable database of all HSN codes (for goods) and SAC codes (for services) — designed for Indian business owners, traders, manufacturers, and accountants who need quick, accurate code identification.

Features of ERP Group's HSN/SAC Finder:

• Search by product name or description (keyword search)
• Search by HSN code number (code lookup)
• View the applicable GST rate for each HSN code
• See the full HSN hierarchy (chapter → heading → subheading)
• Search for both HSN (goods) and SAC (services) codes in one tool
• Mobile-friendly interface — use from your phone at billing time

Step-by-Step: Using the HSN/SAC Finder

Step 1: Go to ERP Group HSN/SAC Finder →

Step 2: Select whether you are searching for goods (HSN) or services (SAC) — or leave it as combined search.

Step 3: Type your product name or description in the search box. Be specific:

• Instead of "cloth" → try "cotton woven fabric"
• Instead of "medicine" → try "medicament retail sale"
• Instead of "machine" → try "automatic data processing machine" or "computer"

Step 4: Review the search results — which will show multiple matching HSN codes with their descriptions and GST rates.

Step 5: Read the code descriptions carefully to identify which best matches your specific product. If multiple codes seem applicable, note all of them and proceed to verify (Method 6 below for uncertain classifications).

Step 6: Note your HSN code and the applicable GST rate — ready to configure in your billing software.

Tips for Better HSN/SAC Finder Results

Use generic terms first: Search "cotton fabric" rather than your brand name "Sharma Cotton Shirting."

Try material/ingredient: Search by the primary material — "polyester," "aluminium," "rubber," "glass."

Use official GST terminology: GST notifications use specific language — "medicament," "pharmaceutical preparation," "woven fabric," "mechanically deboned meat." Use these terms for better results.

Try the chapter first: If you know your product is a textile, look at Chapter 50-63. If it's food, try Chapter 01-24.

Method 2 — CBIC HSN Master Code List

The Official Government Source for HSN Codes

What CBIC Provides

The Central Board of Indirect Taxes and Customs (CBIC) — India's GST administration authority — publishes the official HSN master code list and GST rate schedules. These are the authoritative source for HSN classification in India.

Where to Find CBIC Resources

CBIC Website (www.cbic.gov.in):

• Access the HSN Tariff Schedule (Customs Tariff Act)
• GST Rate Notification 01/2017 CT(Rate) and all subsequent amendments
• FAQs on specific product classifications

GST Council Portal (gstcouncil.gov.in):

• Rate schedules by HSN code
• Clarifications on specific products

How to Use CBIC HSN Schedule

The CBIC HSN schedule is organized by chapter. To find your product:

1. Identify which of the 99 chapters likely contains your product
2. Open that chapter and read through the headings (4-digit codes)
3. Identify the heading that matches your product
4. Read the subheadings (6-digit) to find the most specific match
5. Cross-reference with the GST rate notification to confirm the applicable rate

The chapter notes and section notes are crucial: At the beginning of each HSN chapter, there are legal notes that define what is included and excluded from that chapter. Reading these notes prevents common misclassification errors.

Method 3 — GST Portal Product Search

Using the Government GST Portal Directly

GST Portal HSN Search Feature

The official GST portal (www.gst.gov.in) includes an HSN/SAC search feature that allows taxpayers to search for HSN codes online.

Step-by-Step: GST Portal HSN Search

Step 1: Go to www.gst.gov.in

Step 2: Navigate to the "Search HSN Code" or "Services" → "Tax Rate Finder" section

Step 3: Enter your product description in the search box

Step 4: The portal shows matching HSN codes with their descriptions and applicable GST rates

Step 5: Select the most appropriate code for your product

Advantages and Limitations

Advantages: Official government source, rates are current and authoritative, integrated with GST compliance framework.

Limitations: Search interface may be less user-friendly than dedicated tools like ERP Group's HSN/SAC Finder, results can include many options requiring expert judgment to narrow down.

Method 4 — The Classification Methodology (Top-Down Approach)

The Structured Approach for Complex or Uncertain Products

For products that do not yield obvious results from keyword searches — particularly new products, composite products, or products at the boundary between categories — a structured top-down classification methodology is more reliable than search alone.

The Six-Step Classification Process

Step 1 — Describe Your Product Precisely

Before searching or classifying, write a precise product description:

• What is it made of? (primary material)
• What is its form? (liquid, solid, powder, woven, knitted, assembled)
• What is it used for? (end use/function)
• What is its level of processing? (raw, processed, finished, packaged)
• Who buys it? (industrial, consumer, agricultural use)

Example: "Machine-made woven cotton fabric, plain weave, with 200g/m² weight, 95% cotton content, sold in 44-inch width rolls to tailors."

This precise description immediately points to Chapter 52 (Cotton) → Heading 5209 (woven cotton fabric, ≥85% cotton, >200g/m²).

Step 2 — Identify the Likely Section and Chapter

The 21 HSN sections and 99 chapters follow a logical product progression — from live animals and raw materials to processed goods to machinery to manufactured articles. Match your product description to the most likely chapter:

Step 3 — Read Chapter Notes and Section Notes

Critical step that many searchers skip. At the beginning of each HSN chapter and section, there are binding legal notes that define:

• What products ARE included in this chapter
• What products are EXCLUDED (and where they are classified instead)
• Technical definitions of terms used in the chapter

Example Chapter Note: Chapter 52 (Cotton) Note 1: "This chapter shall not cover cotton yarn or cotton fabric which has been impregnated, coated, covered or laminated with plastics (Chapter 56)."

Without reading this note, a business might classify laminated cotton fabric under Chapter 52 when it should be in Chapter 56.

Step 4 — Identify the Heading (4-digit code)

Within your identified chapter, read through the 4-digit headings to find the one that best describes your product. The heading description is the key matching criterion.

Step 5 — Identify the Subheading (6-digit code)

Within the identified heading, look at the 6-digit subheadings. Note that subheadings are hierarchical — one dash (-) subheadings are broader, two dash (--) subheadings are more specific. Always classify at the most specific applicable level.

HSN General Rules of Classification (GRI): When no subheading specifically covers your product, the General Rules of Interpretation provide the legal framework for classification. GRI 3 (specific over general, mixture rules) and GRI 4 (most similar goods) are particularly important for composite and mixed products.

Step 6 — Verify Against the GST Rate Notification

After identifying the HSN code, cross-reference with the GST Rate Notification (01/2017-CT(Rate) and amendments) to confirm the applicable GST rate. Some products at the same 6-digit HSN level may have different rates for 8-digit subdivisions under India's notifications.

Method 5 — Checking Supplier Invoices and Industry Practice

Learning from Established Practice in Your Sector

Read Your Purchase Invoices

The most practical starting point for a trader: your suppliers have already classified the products they sell you. Their purchase invoices show the HSN code they use for each product. While you should verify that their classification is correct — established large manufacturers and distributors have typically had their products professionally classified.

Important caveat: Supplier HSN codes are not automatically authoritative. If a supplier consistently uses an incorrect code, you would also be incorrect by following them. Large FMCG companies and manufacturers tend to have professionally verified HSN codes; smaller suppliers may have errors.

Industry Associations and Trade Bodies

Industry associations often publish HSN code guidance for their specific sectors — pharmaceutical industry associations for medicine codes, textile associations for fabric codes, auto components associations for parts codes.

For FMCG distributors who need HSN codes for consumer goods, read our guide on GST software for FMCG distributors India.

CA or Tax Consultant Input

For products where you are uncertain — particularly high-value products, new product categories, or composite products — consulting a CA or GST specialist is appropriate. ERP Group's CA Partner Program → connects businesses with CAs who understand product classification.

The CA's professional fee for HSN code verification is a legitimate business expense — and far cheaper than the penalty and interest that can result from systematic wrong classification.

Method 6 — Advance Ruling for Uncertain Classifications

When You Need Legal Certainty on HSN Classification

What is an Advance Ruling Under GST

An Advance Ruling (AR) under Section 97 of the CGST Act allows a registered taxpayer to approach the Advance Ruling Authority (ARA) of their state and receive a binding legal determination on specific GST questions — including HSN classification of products.

When to Seek an Advance Ruling for HSN Classification

An advance ruling is appropriate when:

• Your product could reasonably be classified under two or more HSN codes with different GST rates — and the rate difference is significant
• The product is novel or innovative without existing classification precedent
• Your product is high-value and systematic wrong classification would create large financial exposure
• You have received conflicting advice on the correct HSN code
• Tax authorities have questioned your existing classification

How to Apply for HSN Advance Ruling

1. File Application Form GST ARA-01 with the State Authority for Advance Ruling (SAAR)
2. Provide detailed product description, manufacturing process, materials used, and end use
3. Submit samples if the product is physical
4. Pay the prescribed fee (typically ₹5,000-10,000 per state)
5. Receive a binding ruling — applicable to your specific business and product in the state where applied

Advance ruling is binding on: The applicant taxpayer for their specific product. It is not universally binding on others — but it provides strong support for your classification position.

Common Product Classification Scenarios

Working Through Real Classification Challenges

Scenario 1 — Packaged vs Loose Food Products

Challenge: A trader sells both loose rice (by weight, no brand) and branded packaged rice (in sealed retail bags).

Classification approach:

• Loose unbranded rice → HSN 1006 → Exempt (0% GST)
• Branded packaged rice → HSN 1006 → 5% GST (the branding and packaging creates taxability)

Key insight: The same physical product (rice) has different tax treatment based on whether it is branded and packaged for retail sale. The product description in the GST rate notification specifies "branded and registered" for taxability.

For grain traders, read our guide on billing software for grain traders India.

Scenario 2 — Garment with MRP Straddle

Challenge: A garment manufacturer makes kurtas in different price points — some with MRP ₹850, others with MRP ₹1,200.

Classification approach:
Both use the same HSN (e.g., 6211 for kurta — men's wear)

• Kurta with MRP ≤₹1,000 → 5% GST
• Kurta with MRP >₹1,000 → 12% GST

Key insight: The HSN code is the same for both; the GST RATE differs based on MRP. This is an MRP-based rate differentiation — not an HSN classification difference.

For garment manufacturers, read our guide on ERP for garment manufacturers India.

Scenario 3 — Agricultural vs Household Pesticide

Challenge: A chemical distributor sells the same active ingredient (cypermethrin) in two formulations — one marketed as agricultural crop spray, one marketed as household insect spray.

Classification approach:

• Agricultural pesticide (crop protection) → HSN 3808 → 5% GST
• Household insecticide → HSN 3808 → 18% GST

Key insight: End use determines the rate. The packaging, labelling, and intended use define whether an agrochemical is agricultural (5%) or household (18%).

For chemical manufacturers and traders, read our guide on billing software for chemical manufacturers India.

Scenario 4 — Parts vs Finished Product

Challenge: An auto parts dealer sells car tyres. Are they classified as vehicle parts or as rubber products?

Classification approach:

• New pneumatic tyres for passenger vehicles → HSN 4011 11 → 28% GST
• Inner tubes for car tyres → HSN 4013 → 12% GST
• Retreaded tyres → HSN 4012 → 18% GST

Key insight: Tyres are classified under rubber products (Chapter 40), not vehicle parts (Chapter 87). This requires knowledge that Chapter 87 excludes tyres.

For auto parts dealers, read our guide on billing software for auto parts dealers India.

Scenario 5 — Composite Supply in Construction

Challenge: A construction contractor supplies both materials and construction services together. What HSN/SAC code applies?

Classification approach:
Works contract (where service element is predominant) → SAC 995411/995412 → Works contract GST rates apply (1%, 5%, 12%, or 18% depending on project type).

Key insight: When goods and services are bundled in a construction works contract, the composite supply is classified as a service (SAC) — not split into goods (HSN) and services (SAC) separately. The "principal supply" determines the classification.

How to Verify Your HSN Code is Correct

The 5-Step Verification Process

Verification Step 1 — Cross-Reference with GST Rate Notification

After finding your HSN code, cross-reference with the official GST Rate Notification (Notification 01/2017 CT(Rate) and all subsequent amendments). The notification is organized by Schedule:

• Schedule I: Nil/0% rated goods
• Schedule II: 5% rated goods
• Schedule III: 12% rated goods
• Schedule IV: 18% rated goods
• Schedule V: 28% rated goods

Find your HSN code in the appropriate schedule to confirm both the classification and the rate.

Verification Step 2 — Check Chapter Notes for Exclusions

Read the chapter notes for your identified chapter. Ensure your product is not explicitly excluded from that chapter (and consequently classified elsewhere).

Verification Step 3 — Look for Product-Specific Advance Rulings

The GST Council and AAR (Authority for Advance Rulings) have issued numerous product-specific rulings. Search for rulings on your product type — if a ruling exists for a similar product, it provides strong guidance on the correct classification.

Verification Step 4 — Check Customs Tariff Classification

India's Customs Tariff uses the same HSN system. If your product is imported — the customs classification declared on the import entry is strong evidence of the correct HSN. Check the Bill of Entry for imported products.

Verification Step 5 — Compare with Industry Peers

If your industry peers (distributors of the same product, fellow manufacturers of the same type of goods) consistently use a specific HSN code — this industry practice provides strong support for your classification. Deviation from consistent industry practice requires justification.

Setting Up HSN Codes in Your Billing System

From Finding the Code to Using It Automatically

Finding the correct HSN code is step one. Implementing it correctly in your billing system is step two — and it is where many businesses lose the benefit of correct classification through inconsistent application.

The Product Master Approach

The correct way to implement HSN codes in a billing system is through the product master (sometimes called item master or product catalogue) — where each product is configured once with its HSN code and GST rate, and that configuration is applied automatically to every invoice where the product appears.

Wrong approach: Looking up the HSN code and manually typing it on each invoice — creating inconsistency risk, typing errors, and compliance gaps.

Right approach: Configure HSN code and rate in the product master once — every invoice automatically carries the correct HSN and rate from the master.

What the Product Master Should Include

For each product in your catalogue:

• Product name and description
• HSN code (4 or 6 digit depending on your turnover)
• GST rate (0%, 5%, 12%, 18%, 28%)
• Unit of measurement (for GSTR-1 Table 12 UQC)
• Whether supply is exempt, taxable, or zero-rated (for exports)

ERP Group's GST invoicing system maintains a complete product master with all these attributes — ensuring every invoice generated is HSN-compliant.

Multi-Rate Products — Creating Separate Master Entries

For products where the same physical item has different rates in different contexts (like branded vs unbranded food, or garments at different MRP tiers) — create separate product master entries:

• "Rice — Loose Unbranded" (HSN 1006, Exempt)
• "Rice — Branded Packaged 5kg" (HSN 1006, 5%)

ERP Group supports multiple product variants with different HSN and rate configurations.
