South Central Railway Trisodium Phosphate IS 573 Tender Chittoor Andhra Pradesh 2026

Tender Overview

South Central Railway, under Indian Railways, is seeking Trisodium Phosphate (as per IS 573) for packing/chemical use. The procurement is positioned in Chittoor, Andhra Pradesh 517001 with an unspecified estimated value and unclear EMD details in the published data. The scope emphasizes packing size (kg), shelf life in months, and comprehensive chemical impurity controls (insolubles, P2O3, Na2CO3, NaOH, chlorides, heavy metals, and other contaminants). The tender requires strict IS 573 compliance and involves a supplier evaluation anchored on past SC Railway experience. A key differentiator is supplier capability to meet multiple chemical-spec thresholds and deliver within the contract framework while accommodating optional quantity adjustments. Unique clauses include consignee inspection and a past-performance-based responsiveness criterion, with emphasis on CRAC/Receipt Notes documentation. The opportunity is location-specific to the SC Railway network in Andhra Pradesh, targeting vendors with chemical manufacturing or supply capabilities for government railways.
