Tender Overview
The procurement is issued by the Indian Space Research Organization (ISRO), under the Department of Space, for AEROSPACE QUALITY T-SEALS. The tender has no listed start or end dates and currently shows an estimated value and EMD amount not disclosed. The tender emphasizes that quantities may be adjusted via an option clause up to 25% of bid quantity during contract execution, with extended delivery periods calculated accordingly. A key differentiator is the requirement to ensure the offered seals have at least a 2-year residual market life and are not end-of-life at the OEM. Data Sheet alignment with product specifications is mandatory, or bids risk rejection. A concessional GST rate of 5% applies for this organization, with a government notification referenced for eligibility.
The procurement context centers on ensuring continued supply of certified T-seals suitable for aerospace applications, with OEM authorization, data sheet validation, and long-term supply viability as critical success factors. The absence of BOQ items implies a focus on generic compliance, data integrity, and supplier capability rather than volume-based pricing alone.
