A back-to-back L/C refers to a situation where an intermediary, after receiving a transferable L/C or an ordinary L/C issued by the final buyer, uses that L/C as security to issue another L/C to its own supplier (the actual supplier). Its core feature is that the two L/Cs are independent of each other, but their terms such as amount, shipment date, and validity period are linked, and the intermediary profits from the price difference. Use cases: when it is inconvenient for the intermediary to let the final buyer and the supplier contact each other directly, or when a transferable L/C is not applicable. Precautions: (1) The intermediary must ensure that the terms of the back-to-back L/C match those of the master L/C, especially that sufficient time is allowed for the shipment date and the document presentation period; (2) The risk of soft clauses in the master L/C will be passed on to the back-to-back L/C; (3) Banks usually require the intermediary to provide security or a deposit. Difference from a transferable L/C: A transferable L/C is a transfer of the same L/C, whereas a back-to-back L/C consists of two independent L/Cs, with different issuing banks, and the intermediary bears primary payment liability.
📝 Examples
1. After the Hong Kong intermediary received a USD 1 million sight letter of credit issued by the U.S. buyer, it opened a USD 800,000 back-to-back letter of credit to the mainland Chinese factory, earning a USD 200,000 price difference. (Note: The intermediary uses a back-to-back letter of credit to isolate the buyer and seller and earn the price difference.)
2. Since the master letter of credit stipulates a shipment date of June 30, the intermediary set the latest shipment date as June 10 and the document presentation period as June 15 when opening the back-to-back letter of credit, so as to ensure sufficient time to replace the documents. (Note: The terms of the back-to-back letter of credit must align with the master letter of credit, reserving time for operations.)
