This document discusses the different types of supplies under the Indian Goods and Services Tax (IGST) based on various classifications. It outlines supplies based on location as inter-state, intra-state, or territorial waters. Mixed, composite, and continuous supplies are types based on combinations of goods and services. Supplies are also classified based on the recipient as inward or outward, and based on tax treatment as exempted, zero-rated, non-taxable, or taxable. Key aspects like time of supply and place of supply are also summarized. Place of supply determines whether a transaction is intra-state or inter-state and which state can tax the supply under IGST, SGST, or CGST.
