GST rate amendments redefine restaurant and event-based food supplies, adjust input tax credit conditions, and reclassify transport and e-book supplies. Amendments revise State GST entries by redefining restaurant and food-supply services to separate regular supplies (including certain institutional canteens) from event-based supplies, require that input tax credit on goods and services used in supplying the restaurant service has not been taken, substitute 'value of supply' for 'declared tariff' in several items, define and set the rate for multimodal transportation with accompanying definitions, and create a separate lower-rate classification for supplies consisting only of e-books while leaving other telecommunications and information services at the standard rate.
