To participate in bidding, we must first understand the source of funds of the tenderee. If it is a loan project of an international financial organization, the company participating in the bidding must have the qualification of commodity import and export, otherwise it cannot participate in the bidding. For international procurement projects paid by the tenderer by letter of credit, the companies participating in the bidding must also have commodity import and export qualifications.
In addition, participating in the bidding project must be related to the bidding company or the end user, because most bidding projects have behind-the-scenes operation procedures, and it is basically impossible for a company completely isolated from the tenderer to win the bid.
