What makes a requirement binding here
The Drugs and Cosmetics Act, 1940 and the Drugs and Cosmetics Rules, 1945 made under it. The manufacturing requirements sit in Schedule M to the Rules, which was substantially revised by the Drugs (Amendment) Rules, 2023, notified on 28 December 2023 — a rewrite rather than an update, bringing in a pharmaceutical quality system, quality risk management, qualification and validation, change control, product recall and complaint handling as explicit obligations.
Through a manufacturing licence issued by a State Licensing Authority, with the Central Drugs Standard Control Organisation operating at national level — and the division of labour between them is the thing to get right. Most manufacturing licences are granted and inspected by the state, not the centre; CDSCO handles imports, new drug approvals and central functions, and inspects alongside state authorities. Compliance with revised Schedule M is verified during inspection by CDSCO, the State Licensing Authority and Union Territory administrations.
