In terms of Section 2(30) of the CGST Act, 2017 ‘composite supply’ is defined to mean a supply made by a taxable person to a recipient comprising 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. The illustration appended to the definition of ‘composite supply’ reads as follows:
Where goods are packed and transported with insurance, the supply of goods, packing materials, transport and insurance is a composite supply and supply of goods is the principal supply.
Section 8(a) provides that the composite supply whether involves supply of goods or services shall be decided based on the principal supply forming part of ‘composite supply’. In other words, if the composite supply involves supply of services as principal supply, such composite supply would qualify as supply of services and accordingly the provisions relating to time of supply of services would be applicable. Alternatively, if composite supply involves supply of goods as principal supply, such composite supply would qualify as supply of goods and accordingly, the provisions relating to time of supply of goods would be applicable.
