01Manufacturer's authorization letter
Manufacturer preparesTender wording: “Manufacturer authorization letter required” / “授权书原件”
Must contain
- The tender reference number — not a future order
- The buyer's legal name as written in the tender
- The exact model list with model numbers, not a product family
- The bidder's legal name exactly as it appears on the bid
- A validity period tied to the tender timeline
Most common failure
A generic “we authorise X to sell our products” letter. Evaluation committees treat a letter without the tender reference as non-responsive, because it could have been issued for any purpose.
