7.2.3.2 Circulation of Letter of Credit After signing,with the exporter,a contract agreeing to make payment by L/C,the importer requests his bank to issue a letter of credit in favor of the exporter.If it accepts the importer’s application,the opening bank issues a letter of credit and then informs its foreign branch or correspondent to advise the beneficiary(the exporter),who then examine the letter of credit.If it does not conform to the conditions set in the sales contract,the exporter may request an amendment.If it is an irrevocable letter of credit,and they usually are,it cannot be changed unless all parties agree to amend. After confirming the letter of credit,the exporter delivers the goods to the shipper who then issues a bill of lading.Other documents,such as invoices and insurance documents,are prepared by the exporter.The next step occurs when the exporter draws a her own bank.Usually this bank will investigate the documents and,if they are in order,it will pay the draft.The letter of credit and documents are sent to the opening bank.It is the bank ‘s responsibility to examine the documents in relation to the letter of credit,by new documents,or by amendments.Discrepancies include any one of the following:the letter of credit expired;the draft was not properly drawn;there was no indication on the bill of lading that goods were received on board;there was insufficient insurance;or an invoice description did not match that of the letter of credit.If no discrepancies are found after careful checking,the opening bank will reimburse the money to the exporter’s bank(negotiating bank) in accordance with the terms of the credit.The opening bank then presents the documents to the buyer for payment or acceptance.Documents will be released to the buyer upon his payment of amount due or acceptance of the draft.With the documents,the buyer can take delivery of the goods.
