Section 8 of the CGST Act determines the tax treatment when a supply involves two or more taxable items bundled together. A composite supply (naturally bundled, with one principal supply) is taxed at the rate of the principal supply. A mixed supply (not naturally bundled, offered as a package) is taxed at the highest rate among the constituent supplies.
Legal Framework
| Provision | Content |
|---|---|
| S.2(30) | "Composite supply" defined |
| S.2(74) | "Mixed supply" defined |
| S.2(90) | "Principal supply" defined |
| S.8(a) | Tax treatment of composite supply: rate of principal supply |
| S.8(b) | Tax treatment of mixed supply: rate of supply attracting highest tax |
Composite Supply (S.2(30))
A supply is composite when it:
| Element | Requirement |
|---|---|
| Two or more taxable supplies | Of goods, services, or both |
| Naturally bundled | Supplied in conjunction with each other in the ordinary course of business |
| One is the principal supply | The predominant element for which the bundle exists |
| Not separable | Individual supplies cannot meaningfully be offered independently |
Tax treatment: Entire composite supply taxed at the rate applicable to the principal supply (S.8(a)).
Example: Hotel providing stay (accommodation) + breakfast + laundry + airport pick-up. The principal supply is accommodation. Entire package taxed at the rate applicable to hotel accommodation.
Mixed Supply (S.2(74))
A supply is mixed when it:
| Element | Requirement |
|---|---|
| Two or more individual supplies | Of goods, services, or both |
| Made together for a single price | Combined as a package |
| NOT naturally bundled | Each supply could be offered independently |
| Not a composite supply | Does not meet the "naturally bundled" test |
Tax treatment: Entire mixed supply taxed at the rate of the supply attracting the highest rate among all constituent supplies (S.8(b)).
Example: Diwali gift hamper containing chocolates (5%), dry fruits (12%), and a branded handbag (18%). Not naturally bundled. Entire hamper taxed at 18% (highest rate).
Principal Supply (S.2(90))
Principal supply means the supply which constitutes the predominant element of a composite supply and to which any other supply forming part of that composite supply is ancillary.
Test for principal supply:
- What is the primary purpose for which the customer buys the bundle?
- Which element would the customer not purchase without?
- Which element drives the purchasing decision?
Distinguishing Composite from Mixed
| Test | Composite | Mixed |
|---|---|---|
| Naturally bundled? | Yes (industry practice, customer expectation) | No (artificially combined) |
| Can components be offered separately? | Not meaningfully (ancillary to principal) | Yes (each has independent utility) |
| One predominant supply? | Yes (identifiable principal) | No (no single dominant element) |
| Tax rate | Principal supply rate | Highest rate among components |
| Example | Moving company: transport (principal) + insurance + packing | Gift box: canned food + sweets + aerated drinks |
Worked Examples: How to Tell the Difference
Example 1 (Composite): A 5-star hotel charges Rs.10,000 per night. The package includes room stay, breakfast, Wi-Fi, and gym access.
- Are these naturally bundled? Yes. Hotels routinely offer these together. Customers expect breakfast and Wi-Fi with a room.
- Principal supply? Room accommodation (reason the customer books).
- Tax rate: Rate applicable to hotel accommodation (e.g., 18% for rooms > Rs.7,500).
- The breakfast, Wi-Fi, and gym don't attract separate rates.
Example 2 (Mixed): A store sells a "Festive Hamper" for Rs.2,000 containing: dry fruits (5%), silk scarf (12%), branded perfume (28%), and greeting card (18%).
- Are these naturally bundled? No. A scarf and perfume and dry fruits are not routinely sold together. Each has independent utility.
- Principal supply? None identifiable. No single item dominates the package.
- Tax rate: 28% (highest rate among components = perfume at 28%).
- The entire Rs.2,000 is taxed at 28%, not item-by-item.
Example 3 (Tricky): An electronics store sells a laptop for Rs.60,000 with a laptop bag, mouse, and 1-year warranty.
- Naturally bundled? Yes. Laptops are routinely sold with accessories and warranty. Customers expect them.
- Principal supply? Laptop (the primary purchase).
- Tax rate: Rate of the laptop (18%).
- The bag, mouse, and warranty take the laptop's rate.
Exam tip: Ask yourself: "Would a customer buy these separately?" If yes → mixed. If "These always come together" → composite.

Key Cases
No major judicial precedent yet on S.8 composite/mixed supply classification. The GST Council has issued clarifications through circulars and advance rulings have been made by AARs in specific cases, but no Supreme Court or High Court decision on the core distinction.
Distinctions
| Feature | Composite Supply (S.8(a)) | Mixed Supply (S.8(b)) |
|---|---|---|
| Definition | S.2(30) | S.2(74) |
| Nature | Naturally bundled in ordinary course of business | Not naturally bundled; for single price |
| Principal supply | Identifiable | Not applicable |
| Tax rate | Rate of principal supply | Highest rate among all supplies |
| Separability | Components cannot be meaningfully separated | Components can be offered independently |
| Example | Air travel + meals on flight | Gift hamper with items at different rates |
| Revenue impact | Lower tax (rate of main item) | Higher tax (highest individual rate) |
| Test | Would customers expect these together? | Could each component sell independently? |
Flashcards
Q: What is a composite supply under S.2(30)? A: Two or more supplies naturally bundled in ordinary course of business, where one is the principal supply.
Q: What is a mixed supply under S.2(74)? A: Two or more individual supplies (not naturally bundled) made together for a single price.
Q: At what rate is a composite supply taxed? A: At the rate of the principal supply (S.8(a)).
Q: At what rate is a mixed supply taxed? A: At the rate of the supply which attracts the highest tax rate among all constituents (S.8(b)).
Q: What is the test for "naturally bundled"? A: Whether the supplies are routinely offered together in the ordinary course of business, and whether customers would expect them as a package.
Q: Give an example of composite supply. A: Goods sold with transit insurance and packaging. Principal supply = goods. Entire transaction taxed at the rate of the goods.
Exam Scenario
A store sells a "Back to School" kit containing: notebook set (12%), pen set (18%), geometry box (18%), and water bottle (12%), all packed together for a single price of Rs.500. No individual item is dominant. Determine the GST treatment.
Approach: Test: Are these naturally bundled? No. A notebook, pen set, geometry box, and water bottle are independently sold items. They are artificially combined into a package at a single price. This is a mixed supply (S.2(74)). Since it is not a composite supply (no natural bundling, no single principal supply), the entire supply is taxed at the highest rate among the components. Highest rate = 18% (pen set and geometry box). Entire kit of Rs.500 is taxable at 18% GST.
