HSN and SAC Codes Explained: How to Correctly Classify Goods and Services Under GST

Introduction

Correct classification of goods and services under GST is fundamental to tax compliance. The Harmonised System of Nomenclature (HSN) codes are used for classifying goods, while Services Accounting Codes (SAC) are used for classifying services. Incorrect classification can lead to incorrect GST rates, resulting in tax demands, interest, and penalties. This article provides a comprehensive technical analysis of HSN and SAC codes, including classification principles, practical application, and common pitfalls.

Understanding HSN Codes

What is HSN?

HSN stands for Harmonised System of Nomenclature, an internationally standardised system developed by the World Customs Organisation (WCO). India's Customs Tariff Act, 1975 incorporates the HSN at the 8-digit level.

HSN Code Structure

HSN codes are structured as follows:

• 2-digit: Chapter (e.g., 85 for Electrical machinery)
• 4-digit: Heading (e.g., 8523 for Discs, tapes, solid-state non-volatile storage devices)
• 6-digit: Sub-heading (internationally harmonized)
• 8-digit: Tariff item (India-specific)

HSN Code Requirements Under GST

• Aggregate turnover up to ₹5 crore: 4-digit HSN code required
• Aggregate turnover above ₹5 crore: 6-digit HSN code required
• Exports and imports: 8-digit HSN code required

Understanding SAC Codes

What is SAC?

SAC stands for Services Accounting Code, used for classifying services under GST. SAC codes are based on the United Nations Central Product Classification (UNCPC) system.

SAC Code Structure

SAC codes are 5-digit codes:

• First two digits: 99 (designated for services)
• Next three digits: Service category

Common SAC Codes

The Classification Framework

Legal Framework for Classification

Section 9(1) of the CGST Act levies tax on all intra-State supplies at rates notified by the Government. The rates are prescribed in the schedule to:

• Notification 1/2017 (for goods)
• Notification 11/2017 (for services)

The classification exercise is therefore:

1. Determine the correct HSN/SAC code for the supply
2. Look up the applicable rate in the notification

General Rules of Interpretation (GRI)

The General Rules of Interpretation of the HSN provide the framework for classification:

1. Rule 1: Classification is determined by the terms of the headings and any relative Section or Chapter Notes
2. Rule 2: Incomplete or unfinished articles, and mixtures and combinations
3. Rule 3: Where goods are classifiable under two or more headings, the most specific description prevails; if equally specific, the essential character determines classification; if neither applies, the heading that occurs last in numerical order
4. Rule 4: Goods not classifiable under Rules 1-3 are classified under the heading appropriate to the goods to which they are most akin
5. Rule 5: Containers and packing materials
6. Rule 6: Classification of goods in the sub-headings of a heading

Trade Parlance Test

The trade parlance test is a key principle in classification disputes. Goods should be classified according to how they are understood in the trade, not based on technical or scientific definitions.

Functional Use Test

The functional use test considers the primary function or use of the goods or services. This is particularly relevant for products that could be classified under multiple headings.

Composite and Mixed Supplies

Composite Supply

Under Section 2(30), a composite supply means a supply made by a taxable person to a recipient consisting of two or more taxable supplies of goods or services or both, or any combination thereof, which are naturally bundled and supplied in conjunction with each other in the ordinary course of business, one of which is a principal supply.

Tax Treatment: A composite supply shall be treated as a supply of such principal supply.

Mixed Supply

Under Section 2(74), a mixed supply means two or more individual supplies of goods or services, or any combination thereof, made in conjunction with each other by a taxable person for a single price where such supply does not constitute a composite supply.

Tax Treatment: A mixed supply shall be treated as a supply of that particular supply which attracts the highest rate of tax.

Common Classification Disputes

Software Classification

The classification of software depends on the form of delivery:

• Pre-packaged software (shrink-wrap): Treated as goods (HSN 8523) with 18% GST
• Customized software: Treated as services (SAC 998313/998314) with 18% GST
• SaaS (Software as a Service): Treated as services with 18% GST
• Digital downloads: Often treated as services

Digital Products

Digital products like e-books, music downloads, and software downloads are often treated as services, even though they resemble goods in functionality.

Multi-Component Contracts

Contracts involving multiple components (goods and services) require careful analysis to determine whether they constitute composite supply, mixed supply, or separate supplies.

Practical Compliance Strategies

Classification Best Practices

1. Understand the Product/Service: Thoroughly understand the nature, function, and use of the goods or services.

2. Consult HSN Explanatory Notes: The HSN Explanatory Notes provide detailed guidance on classification.

3. Consider Advance Ruling: Where classification is uncertain, consider obtaining an advance ruling under Section 97(2)(a).

4. Maintain Documentation: Document the basis for classification decisions.

5. Regular Review: Review classification decisions regularly, especially when there are changes in the product/service or notifications.

During Audit Defence

If classification is disputed during audit:

• Challenge the basis: Ensure the officer has proper grounds for reclassification
• Provide documentation: Submit all relevant documents supporting the classification
• Consider trade parlance: Argue based on how the product is understood in the trade
• Consider functional use: Argue based on the primary function or use
