For more than two decades, the indian space research organisation ISRO tenders ecosystem has been one of the most advanced procurement environments in India. Companies supplying components to India’s space missions must comply with strict quality, technical, and digital procurement requirements.
The ISRO eprocure portal serves as the official platform where all ISRO tenders, vendor registrations, and eProcurement processes are managed. Suppliers that successfully complete ISRO vendor registration gain access to opportunities across multiple space centres such as VSSC, SAC, URSC, and SDSC SHAR.
However, entering the ISRO supply chain is not simple. According to Tender18 procurement intelligence, nearly 95% of first-time suppliers fail during registration or bid submission due to technical compliance errors. Through its enterprise tender intelligence system, Tender18 provides structured workflows, verified documentation templates, and real-time monitoring of ISRO tenders to help suppliers participate successfully.
The official ISRO tender portal operates on the Department of Space procurement infrastructure.
Primary Portal:
isroeproc.gov.in
