A copper supplier is not chosen on rate alone. The real cost of a non-ferrous contract sits in three places: weighbridge accuracy, grade conformity at loading and post-dispatch documentation. A reliable supplier minimises all three.
The 12-point checklist
- GST registration verifiable on the GSTN portal
- Udyam / MSME / Pollution Control consent where applicable
- Member of recognised industry associations (e.g. MRAI)
- Bank-verified Account, clean Form 26AS history
- On-site or third-party weighbridge calibration certificate
- XRF analyser available at loading point
- ISRI specification referenced on PI/PO
- Photo and video of bale prior to loading
- GST e-invoice and e-way bill within statutory timelines
- Transparent LME-discount pricing basis
- Reverse-logistics policy for grade disputes
- Long-term capacity commitment in writing for repeat buyers
Red flags
- Verbal quotes without grade reference or LME basis
- Refusal to share XRF reading at loading
- Pressure to pay 100% in advance to an unfamiliar account
- Inability to issue e-invoice within 24 hours of dispatch
Pre-qualification visit
For any contract over 5 MT/month, schedule a one-day audit of the supplier's premises. Inspect the storage area, weighbridge, sorting line, XRF setup and accounts function. Twenty minutes of verification saves 20 lakh of disputes over the year.
Buy from suppliers who would still take your call after the contract is closed.
