8. How to Register as a Defence Vendor: Complete Process

1. 1. Quality System Certification: Obtain ISO 9001:2015; aerospace suppliers require AS9100 Rev D.
2. 2. Portal Onboarding: Register on targeted DPSU portals and CPPP with Class 3 DSC.
3. 3. DGQA / DGAQA Registration: Secure vendor registration with the Directorate General of Quality Assurance.
4. 4. Security & IB Vetting: File background verification forms for directors and factory facilities.
5. 5. Sample Qualification: Submit prototype components for laboratory testing and environmental qualification.

9. Security Clearance & IB Vetting Protocols

Bidding on classified defence projects mandates security clearance issued by the Ministry of Home Affairs (MHA) through the Intelligence Bureau (IB). The clearance process evaluates corporate shareholding structures (ensuring compliance with GFR Rule 144(xi) land-border restrictions), citizenship of directors, and physical security measures at manufacturing plants.

10. Defence Offset Policy: Subcontracting Goldmine for MSMEs

Foreign OEMs winning capital contracts above ₹2,000 crore must discharge offset obligations equal to 30% or more of the contract value. Foreign contractors discharge offsets by procuring components, sub-assemblies, and software from Indian MSMEs, creating tens of thousands of crores in tier-2 supply opportunities.
