Usance Letter of Credit

An importer wants goods now but needs time before paying, while a seller wants the comfort of a bank's documentary undertaking, and a usance letter of credit combines a letter of credit with a future payment date. The seller presents required documents and, if they comply, payment is due at the defined maturity.

The ICC's UCP 600 rules describe deferred payment and acceptance credits when incorporated, and ICC Academy explains types of documentary credit, though the specific credit wording controls dates, documents and bank roles. A contract saying "90 days" is incomplete without a starting event.

A credit may state payment 90 days after the shipment date, after the bill of lading date or after presentation, and these can produce different due dates, so the parties should agree the trigger before shipment, since an invoice's ordinary due date does not automatically change the bank's obligation under the credit. The seller must present the documents required by the credit, which may include an invoice, transport document, insurance evidence and certificates, and banks examine documents, not the physical quality of the goods.

A compliant presentation can create a bank obligation even if the buyer later complains about the shipment under its sale contract, whereas discrepancies such as a misspelled consignee, late shipment or wrong document date can delay or prevent the expected payment undertaking. The seller should review the credit promptly and request amendments before shipping if terms are impossible, rather than wait until papers reach the bank.

The issuing bank undertakes obligations under the credit subject to its terms and rules, while a nominated or confirming bank may have a different role, so identify which institution owes what. For the importer, usance can support working capital because goods may be received and sold before the maturity date, though customs delays or slow customers can leave the importer owing the bank before it collects cash.

For the exporter, waiting until maturity ties up receivables, so it may ask a bank to discount or prepay the deferred obligation, with availability, rate, recourse and bank credit risk depending on the arrangement, and a real offer should be obtained before promising early cash. Fees include issuance, confirmation, amendment and discounting charges where applicable, and the sale contract should allocate costs between buyer and seller, since a low invoice price can become less attractive after bank fees.

Consider an illustrative credit of $500,000 payable 90 days after the shipment date shown on a specified document. If the document's qualifying date is 1 June and the 90-day count follows the credit's convention, payment falls around late August, but the exact calendar calculation and bank interpretation should be verified, and maturity should not be inferred from the day the goods reach the port.

Track credit deadlines such as latest shipment date, presentation period, expiry and maturity, because they serve different purposes and a shipment can be timely yet documents presented too late. A usance LC is a timed documentary payment arrangement, so read the exact event that starts the clock, the documents required and each bank's role.

A calendar shared among sales, logistics and treasury helps prevent an avoidable discrepancy, and the importer should model fees and cash due at maturity, since the credit can bridge trade timing only if documents comply and both parties understand the financing exposure.
