Meet Vikram, who runs a small online business selling “ayurvedic hair oil” and “herbal shampoo.” He’s been using the same HSN code for both—but recently, a customer’s ITC was rejected because his hair oil should be classified under cosmetics (different rate) while shampoo under “preparations for hair” (another rate). Now he faces a ₹47,000 tax demand.
You’re not alone. Wrong HSN/SAC codes are among the top 5 reasons for GST notices, according to CBIC data. With over 12,000 HSN codes and 500+ SAC codes, finding the right one feels like searching for a needle in a haystack.
But here’s the truth: getting the code right isn’t just compliance—it’s money. Wrong code means:
-
Wrong tax rate (pay too much or too little)
-
ITC denied to your customers (who will then refuse payment)
-
Mismatches in GSTR-1 and GSTR-3B
-
Notices demanding tax + interest + penalty

HSN VS SAC: WHAT’S THE DIFFERENCE?
Before finding codes, understand what you’re looking for.
HSN (Harmonized System of Nomenclature)
For Goods (Products)
-
Developed by World Customs Organization
-
Used by 200+ countries
-
21 sections, 99 chapters, over 12,000 codes
-
First 6 digits are international; next digits are country-specific
SAC (Service Accounting Codes)
For Services
-
Developed by India for GST
-
Based on UN Central Product Classification
-
20+ chapters, 500+ codes
-
All codes start with “99” (section for services)
Quick Comparison
| Aspect | HSN (Goods) | SAC (Services) |
|---|---|---|
| Applies to | Physical products | Services, work contracts |
| Code Format | 4, 6, or 8 digits | Usually 6-8 digits |
| First Digits | 01-98 (chapters) | 99 (always starts with 99) |
| International | Yes (first 6 digits) | India-specific |
| Example | 1006 (Rice) | 9983 (Business services) |
*Source: CBIC GST Tariff *
Simple Rule: If it’s a physical item you can touch → HSN. If it’s work done, expertise, or experience → SAC.
HSN/SAC CODE STRUCTURE DECODED
Understanding what those digits mean helps you verify if you’re in the right ballpark.
HSN Code Structure (8 Digits)
| Digits | What They Represent | Example: 1006 30 10 |
|---|---|---|
| 1-2 | Chapter (broad category) | 10 = Cereals |
| 3-4 | Heading (specific product group) | 06 = Rice |
| 5-6 | Sub-heading (international standard) | 30 = Semi-milled/wholly milled rice |
| 7-8 | Tariff item (India-specific) | 10 = Basmati rice |
SAC Code Structure (6-8 Digits)
| Digits | What They Represent | Example: 9983 12 |
|---|---|---|
| 1-2 | Section (always 99 for services) | 99 = Services |
| 3-4 | Division (broad service category) | 83 = Business services |
| 5-6 | Group (specific service) | 12 = Legal services |
Digit Requirements by Turnover
| Annual Turnover | HSN Digits Required | SAC Digits Required |
|---|---|---|
| Up to ₹5 crore | Optional (4 digits recommended) | Optional |
| ₹5 crore – ₹10 crore | 4 digits mandatory | 4 digits recommended |
| Above ₹10 crore | 6 digits mandatory | 6 digits recommended |
| Export/Import | 8 digits mandatory | Not applicable |
*Source: Notification No. 12/2024 – Central Tax *
Pro Tip: Even if optional, always use at least 4 digits. It prevents rate errors and makes annual return filing easier.
STEP-BY-STEP GUIDE TO FIND ANY HSN/SAC CODE
Follow these steps systematically to zero in on the correct code.
Step 1: Identify Broad Category (Chapter)
For Goods (HSN):
-
Think about the product’s nature
-
Refer to the 21 sections (e.g., Section I: Animal Products, Section VI: Chemicals)
-
Find the chapter (01-98) that fits
Common HSN Chapters:
| Chapter | Category |
|---|---|
| 01-05 | Animal products |
| 06-14 | Vegetable products |
| 15 | Fats and oils |
| 16-24 | Food preparations |
| 25-27 | Mineral products |
| 28-38 | Chemicals |
| 39-40 | Plastics and rubber |
| 41-43 | Leather |
| 50-63 | Textiles |
| 64-67 | Footwear, headgear |
| 68-70 | Stone, cement, ceramics |
| 71 | Pearls, precious stones |
| 72-83 | Metals |
| 84-85 | Machinery, electronics |
| 86-89 | Vehicles |
| 90-92 | Instruments, clocks |
| 94-96 | Furniture, toys, misc |
For Services (SAC):
-
All services start with 99
-
Next two digits: Division (broad category)
Common SAC Divisions:
| Division | Service Category |
|---|---|
| 995 | Construction services |
| 996 | Real estate services |
| 997 | Leasing/rental services |
| 998 | Business services |
| 999 | Community services |
Step 2: Narrow Down with Keywords
Use descriptive keywords:
-
For “wooden table”: furniture → wood furniture → table
-
For “website design”: business services → IT services → web design
-
For “organic honey”: vegetable products → honey → natural honey
Step 3: Use Official Tools
Method A: India Tax Tools HSN/SAC Finder (Recommended)
- Visit https://indiataxtools.com/hsn-sac-finder
- Type product/service name (e.g., “laptop,” “legal advice”)
- Get instant code + GST rate
- Download product master
Method B: GST Portal
- Log in to https://www.gst.gov.in
- Go to Services > Returns > HSN/SAC
- Use search function
- Download full HSN/SAC lists
Method C: CBIC Tariff
- Download “Indian Customs Tariff” from CBIC website
- Search manually by chapter
Step 4: Verify with GST Rate
Once you have a potential code, cross-check with GST rate:
-
Is the rate what you expect? (5%, 12%, 18%, 28%)
-
Does it match industry practice?
-
Check with trade associations if unsure
Example: If you think “ayurvedic hair oil” is 5% (medicines) but find HSN 3305 (cosmetics) with 18% rate, you likely have the wrong code.
Step 5: Consult Product Master
Create a product master in your accounting software with:
-
Product name
-
HSN/SAC code
-
GST rate
-
UQC (Unit Quantity Code)
Update annually when rate changes are announced.

COMMON MISTAKES AND HOW TO AVOID THEM
| Mistake | Example | Consequence | Solution |
|---|---|---|---|
| Wrong chapter | Classifying “wooden furniture” under wood (Chapter 44) instead of furniture (Chapter 94) | Wrong rate, ITC denied | Think function, not material |
| Too generic | Using “9983” for all business services | Rate wrong for sub-category | Use 6-digit codes |
| Ignoring updates | Using 2024 rates in 2026 | Short payment + interest | Update product master annually |
| Mixing goods and services | Consulting + software under same code | Mismatch in returns | Separate HSN and SAC |
| Insufficient digits | Using 4 digits when 6 required (turnover >₹10cr) | Penalty | Check turnover thresholds |
| Copy-paste errors | Using competitor’s code without verification | Wrong product mapped | Verify each product |
| Not documenting | No product master | Inconsistent codes | Maintain master list |
Real Case Study
A Gujarat-based textile exporter used HSN 5208 (cotton fabric) for all cotton products—including made-ups like bedsheets. Bedsheets should be HSN 6302 (textile made-ups). Result:
-
Wrong rate (5% vs 12% for made-ups)
-
₹8.4 lakh tax demand
-
₹1.5 lakh interest
-
Customer ITC denied → lost contract
Lesson: Specificity matters. Bedsheets aren’t fabric—they’re made-ups.

FREQUENTLY ASKED QUESTIONS
Q1: What is the difference between HSN and SAC?
HSN is for goods (products you can touch). SAC is for services (work done, expertise). HSN codes start with 01-98; SAC codes always start with 99 .
Q2: How many digits of HSN/SAC are mandatory?
| Turnover | HSN Digits | SAC Digits |
|---|---|---|
| Up to ₹5 crore | Optional (4 recommended) | Optional |
| ₹5-10 crore | 4 mandatory | 4 recommended |
| Above ₹10 crore | 6 mandatory | 6 recommended |
| Exports | 8 mandatory | Not applicable |
Q3: Where can I find HSN/SAC codes for free?
Use India Tax Tools HSN/SAC Finder for instant lookup. Also available on GST portal (login required) and CBIC website.
Q4: What if I use the wrong HSN code?
Consequences:
-
Wrong tax rate → short/excess payment
-
Interest @18% on short payment
-
Penalty up to ₹10,000 per invoice
-
ITC denied to customers
-
Mismatch notices from department
Q5: Can I use the same HSN code for similar products?
Only if they fall under the same sub-heading. For example, different smartphone models can use same 851712. But smartphone and charger? Different codes (charger is 8504).
Q6: Does HSN code determine GST rate?
Yes. Each HSN/SAC code maps to a specific GST rate (0%, 5%, 12%, 18%, 28%). However, some codes may have multiple rates based on product variants—check notifications.
Q7: How often are HSN/SAC codes updated?
Internationally, HSN is updated every 5 years. India-specific changes happen annually through Finance Act and GST Council decisions. Always check at start of financial year.
Q8: What is UQC in GST?
UQC = Unit Quantity Code. It’s the unit of measurement (kg, meter, piece, etc.) used with HSN codes. Must be mentioned on invoices. Common UQCs: KGS (kg), MTR (meter), NOS (numbers), LTR (litre).
Q9: Do I need HSN code for exports?
Yes. For exports, you need 8-digit HSN (Indian Tariff Code) for customs clearance. This matches with ITC (HS) codes used by importing countries.
Q10: Can I use HSN/SAC code from competitor’s invoice?
You can, but verify it first. Competitors may have errors. Always cross-check with official finder tools.
