Mixed Supply Under GST: Single Consideration, Multiple Goods and the Highest Tax Rate

1. Background: Why Mixed Supply Matters Under GST

India’s Goods and Services Tax (GST) regime consolidated several indirect taxes into a unified structure. Within this framework, real-world transactions often involve multiple goods or services supplied together—festival hampers, school kits, combo offers, and corporate gift packs are now routine.

The key legal question in such situations is:

  • Should the entire package be taxed at the rate applicable to the main item in the bundle?
  • Or must the entire consideration be taxed at the highest rate applicable to any component in the bundle?

The Central Goods and Services Tax Act, 2017 (CGST Act) addresses this issue through the concepts of composite supply and mixed supply.

  • Section 2(74) defines mixed supply.
  • Section 2(30) defines **composite supply`.
  • Section 8(b) mandates that a mixed supply is taxed at the rate applicable to the component that attracts the highest GST rate.

This distinction has real commercial implications, especially when even a small higher-taxed product included in a bundle can elevate the rate applied to the entire package. The ruling in M/s DOMS Industries Pvt. Ltd. is a recent and practical illustration of this effect.

2. Statutory Definition: What Is a Mixed Supply?

“Mixed supply” under Section 2(74) of the CGST Act refers to:

Two or more individual supplies of goods or services or both, made together by a taxable person for a single price, which do not constitute a composite supply.

The statutory illustration in Section 2(74) speaks of a pack containing canned foods, sweets, chocolates, cakes, dry fruits, aerated drinks, and fruit juices sold for one consolidated price. Each item:

  • Has its own independent commercial identity; and
  • Can be sold separately without depending on the other items.

When such items are sold together for one consideration, and the combination is not a composite supply, it is treated as a mixed supply.

2.2 Core elements of mixed supply

From the definition, three essential conditions emerge:

  • Multiplicity of supplies:

    • There must be two or more distinct supplies of goods or services or both.

  • Single consideration:

    • The supplies are offered together for one consolidated price.

  • Exclusion of composite supply:

    • The bundle should not qualify as a composite supply under Section 2(30).

The third condition is crucial. One should not classify a bundled transaction as a mixed supply solely because multiple items are sold together. The first analytical step is always to test whether the transaction qualifies as a composite supply. Only if the answer is “no” does the analysis move to mixed supply.

3. Composite Supply vs Mixed Supply: Conceptual Distinction

3.1 Composite supply under Section 2(30)

Section 2(30) defines composite supply as:

  • A combination of two or more taxable supplies;
  • Supplied together in the ordinary course of business;
  • Naturally bundled; and
  • Containing one principal supply to which the others are ancillary.

Section 2(90) defines principal supply as the predominant element of the composite supply, to which other supplies are incidental or supportive.

3.2 Key comparative features

The difference between composite and mixed supplies can be captured along the following lines:

Basis Composite Supply Mixed Supply
Bundling nature Naturally bundled in ordinary course of business Not naturally bundled
Principal supply Exists; one supply is principal, others are ancillary No “principal supply” in statutory sense
Single price May or may not be for a single price (composite supply can be) Must be supplied for one price
Tax treatment Taxed at rate of principal supply (Section 8(a)) Taxed at highest rate among components (Section 8(b))
Typical example Goods with transport & insurance in a single contract Gift hamper of unrelated products at one consideration

The GST Council, in its FAQs and guidance materials, has consistently underlined:

  • Composite supply → treated as a supply of the principal supply.
  • Mixed supply → treated as a supply attracting the highest rate among its components.

4. Section 8: Tax Consequences of Composite and Mixed Supplies

Section 8 of the CGST Act codifies the tax treatment for these bundled supplies:

  • Section 8(a):

    A composite supply is treated as the supply of its principal supply.
    Result:

    • The GST rate applicable to the principal supply applies to the whole bundle.

  • Section 8(b):

    A mixed supply is treated as the supply of that component which attracts the highest rate of tax.
    Result:

    • The entire consideration for the package is taxed at this higher rate.

The evident legislative intent is to prevent structuring multiple independent supplies into a single package merely to avail a lower overall rate, while still allowing naturally bundled, principal–ancillary transactions to be taxed more logically as composite supplies.
