  2. CLA (Central Licensing Authority): It’s the body that is responsible for the regulation of import device licensing & manufacturing of Class C & D Medical Devices. This Authority may also avail services of a notified body for the purpose of inspection of the manufacturing site of Class C & D Medical Devices. CLA is responsible for regulating rules & procedures for IVDs. It also regulates imports of all IVD classes along with the manufacture of Class C & D IVDs. It is responsible for the Registration of IVDs & Notified Medical Devices. It also approves new IVDs & evaluates their Clinical Performance & quality check-up. Central Licensing Authority grants Registration of labs for performing regular evaluations & tests. CLA grants licenses for the purpose of importing/manufacturing all classes of IVDs.

Principal Requirements for Medical Devices and IVDs

The principal requirements for both IVDs and Medical Devices are the QMS (Quality Management System), risk management, meeting the essential principles of safety & performance, design & development, manufacturing information & labelling. In general, meeting the requirements of certain standards like ISO 13485:2016 Medical Devices[1] – QMS – Requirements for regulatory purposes, ISO 14971:2019 Medical Devices; Application of Risk Management to medical devices & relevant guidance documents will provide a presumption of conformity with the vital principles of safety & performance.

Development and design principles apply for both Medical Devices and IVDs, starting with design planning from design inputs to outputs to verification & validation testing and capturing design changes. Manufacturing process & controls, descript of main systems or critical processes & description of critical assay ingredients, where relevant, are identical for both Medical Devices and IVDs.

There is no major difference in labelling requirements for Medical Devices and IVDs except for the particular symbols used to identify a medical device and/or IVD, recognised by similar but separate ISO standards.


The market of India has been a huge attraction to Medical Devices and IVDs manufacturers. However, there are many challenges ahead for the Regulatory Body in India, as it is at its starting phase & the regulations and rules must be amended & improved over time.
