It adds 'or 12AB' after '12AA', substitutes an explicit entry for temporary or permanent transfer or permitting the use or enjoyment of Intellectual Property right, inserts a job-work item for manufacture of alcoholic liquor for human consumption, reclassifies manufacturing and related services, distinguishes admissions to parks and casinos/sporting events with differing rates, updates explanatory cross-references, and adds multimodal transport of goods within India to the Scheme of Classification of Services. The notification is effective from the stated commencement date.
