Supplier Verification Standards
GST & Trade License
Valid GST registration and trade license verified for all listed suppliers. Invoicing compliance mandatory.
Manufacturer Authorization
For brand-specific products (e.g., UltraTech cement, Tata Tiscon steel), supplier must hold a valid dealer authorization letter from the manufacturer.
Weighbridge Slip History
Delivery weight verification using NABL-certified weighbridges. We audit past weighbridge slips and cross-check against invoiced quantities.
MTC Documentation Practice
Suppliers must consistently provide Manufacturer Test Certificates with every structural material batch. No MTC = no delivery accepted.
