For those travelling abroad, this letter will ensure that issuing banks take projects into account in some foreign banks. For international trade, the seller may be required to deliver goods to a shipyard in order to meet the requirements of the certification agreement. Once the goods are delivered, the seller receives documents attesting to the delivery and the documents are forwarded to the bank. In some cases, simply placing the shipment on board a ship triggers the payment, and the bank has to pay – even if something happens with the shipment. When a crane falls on the merchandise or the ship sinks, it is not necessarily the seller`s problem. A letter of credit is a document from a bank that guarantees payment. There are different types of letters of credit, and they can offer security when buying and selling products or services. Some countries have created statutes for letters of credit. For example, most jurisdictions in the United States (U.S.) have adopted Article 5 of the Single Trade Code (UCC). These statutes are designed to be associated with the rules of market practice, including UCP and PSI98. These rules of conduct are taken into account in the transaction with the agreement of the parties. The latest version of the UCP is the UCP600 effective July 1, 2007. Since UCP is not a law, the parties must include them in their agreements as ordinary contractual provisions.
However, they remain an essential part of market practice and are an essential basis for financial law. Why does the seller ask for a loan? The seller wants more confidence for the buyer to pay. Maybe this buyer and seller never collaborated, or the order could be large enough to cause serious financial hardship if something goes wrong. For example, if the seller spends money on the manufacture and shipping of goods, the seller wants to recover those costs. The buyer cannot pay for several reasons (the buyer`s property could be confiscated for some reason, the buyer could go bankrupt, and so on). Accreditation has been used in Europe since ancient times.  Letters of credit were traditionally governed by internationally recognized rules and procedures, not by national law. In 1933, the International Chamber of Commerce oversaw the preparation of the first uniform practice in documentary credit (UCP) and created a voluntary framework for commercial banks around the world.
 The details are important: It is important that the bank recovers all the details correctly. The LOC is a legally binding document and these documents are interpreted exactly as they are written. Here too, the LOC is separate from the sales contract and is based on documents – not executed actions – so you can`t assume that everything works if an error occurs in the LOC.
