Section 8 of The Central Goods and Services Tax Act, 2017
Original Text
The tax liability on a composite or a mixed supply shall be determined in the following manner, namely:—
(a) a composite supply comprising two or more supplies, one of which is a principal supply, shall be treated as a supply of such principal supply; and
(b) a mixed supply comprising two or more supplies shall be treated as a supply of that particular supply which attracts the highest rate of tax.
Visual Summary
Composite Supply
Nature: Naturally Bundled
Example: Mobile Phone + Charger
Tax Rate: Rate of Principal Supply (Phone)
Mixed Supply
Nature: Artificially Bundled
Example: Gift Hamper (Chocolates + Juice)
Tax Rate: Highest Rate in the Bundle
Summary
Section 8 acts as the statutory tool to determine the tax rate when multiple goods or services are sold together for a single price. In the GST regime, products are often bundled (e.g., a hotel room with breakfast, or a laptop with a bag). This section classifies these bundles into two categories to prevent tax evasion and ensure clarity:
- Composite Supply (Section 8(a)): These are items that are “naturally bundled” in the ordinary course of business. You cannot easily separate them. The tax rate applied is that of the Principal Supply (the main product).
- Mixed Supply (Section 8(b)): These are items bundled together artificially, usually to make a sale attractive (e.g., a Diwali hamper). Since they can be sold separately, the law discourages this by taxing the entire bundle at the highest rate applicable to any single item in the package.
In-Depth Analysis
1. The Concept of “Naturally Bundled”:
The core differentiator between Composite and Mixed supply is whether the bundle is “natural.” While the Act does not explicitly define “naturally bundled,” industry practice and consumer perception are key. If the recipient expects the ancillary service (like transport or insurance) to accompany the main product, it is likely a Composite Supply.
2. Principal Supply Dominance:
In a Composite Supply, the “Principal Supply” is the predominant element. For example, in a CIF (Cost, Insurance, and Freight) contract, the goods are the principal supply, while insurance and freight are ancillary. Section 8(a) ensures that the ancillary components do not attract a separate (and potentially higher) tax rate.
3. The “Mixed Supply” Trap:
Section 8(b) serves as a deterrent against tax arbitrage. If a supplier tries to bundle a 28% tax item with a 5% tax item and sells it as a “kit” to pay 5% on the whole, Section 8(b) mandates that the entire kit is taxed at 28%. This forces suppliers to either unbundle the items (bill separately) or pay the highest rate.
Deep Research & Legal Precedents
The application of Section 8 has been heavily influenced by judicial interpretation, particularly regarding what constitutes a “composite supply” versus a separate service.
1. Landmark Supreme Court Ruling on Ocean Freight
Citation: 2022 (61) G.S.T.L. 257 (S.C.)
The Supreme Court ruled that in a CIF contract, the supply of goods and the supply of transportation services are a composite supply. The Court held that since the importer pays customs duty on the value of goods (which includes freight), levying a separate IGST on the “ocean freight” component would violate the principle of composite supply under Section 8. The goods are the principal supply, and the freight is ancillary.
2. Exemption of Ancillary Services
Citation: 2019 (20) G.S.T.L. 375 (Guj.)
The Gujarat High Court held that ancillary services provided by power distribution companies (like meter rentals and testing fees) are naturally bundled with the transmission of electricity. Since the principal supply (electricity) is exempt, the ancillary services are also exempt under Section 8(a).
3. Deemed Composite Supplies (Solar Power)
To resolve disputes in the Solar Power sector regarding whether a plant setup is a supply of goods (panels) or services (works contract), the government issued Notification No. 24/2018-Central Tax (Rate). This overrides standard Section 8 analysis by mandating a deemed valuation:
- 70% of the contract value is deemed as Goods (Solar Panels).
- 30% is deemed as Services (Engineering/Installation).
Practical Examples
Example 1: The Airline Ticket (Composite Supply)
When you buy an airline ticket, it includes the flight (transport), food on board, and insurance. These are naturally bundled. The principal supply is transportation of passengers. Therefore, the entire ticket value is taxed at the rate applicable to air travel (e.g., 5% for economy), not the rate for food (5% or 18%) or insurance (18%).
Example 2: The Corporate Gift Pack (Mixed Supply)
A company sells a gift pack containing a leather wallet (28% GST), a pen (12% GST), and a diary (12% GST) for a single price of ₹5,000. These items are not naturally bundled; they can be sold separately. This is a Mixed Supply. The entire pack will be taxed at 28% (the highest rate in the bundle).
Example 3: Printing Services
If a client provides content to a printer to print an annual report, the principal supply is the service of printing (paper is ancillary). However, if a printer sells standard diaries where the printer owns the content/design, it is a supply of goods.
Key Takeaways
-
✓
Identify the Bundle: Determine if the supply consists of two or more taxable supplies sold for a single price. -
✓
Natural vs. Artificial: If industry practice suggests they go together (e.g., machinery + installation), it is Composite. If not, it is Mixed. -
✓
Tax Liability: Composite = Principal Rate. Mixed = Highest Rate. -
✓
Invoicing Strategy: To avoid the “Mixed Supply” highest rate tax, businesses should invoice unrelated items separately.

Conclusion
Section 8 is a critical provision for determining tax liability in complex commercial transactions involving bundles. Correct classification between Composite and Mixed supply is essential to avoid litigation and ensure correct tax payment. While the concept of “naturally bundled” is subjective, reliance on Supreme Court judgments like Mohit Minerals provides clarity that ancillary elements follow the principal supply’s tax treatment.
