I would like to get some guidance with the following question

One of Colossal's suppliers in the country of Edfin no longer wants to supply needed raw materials for Colossal's factories in the United States, unless Colossal agrees to pay them by opening a letter of credit. Up to now, the company has paid them after delivery to the United States, which has allowed Colossal to inspect the quality of the shipments before sending payment. What are the ramifications of granting Edfin's request?
