The commercial letter of credit is a standard form of payment and one of the earliest payment methods used to guarantee transactions in international commerce. BFK INVESTMENT, thanks to fruitful collaboration contracts, with various intermediaries issuing letters of guarantee around the world, can help you obtain two types of letters of credit: commercial (also known, as documentary letters of credit) and SBLC (standby letter of credit). Generally, our partners can provide you with unsecured letters of credit, which means you do not have to block funds or other real guarantees to obtain a credit letter.
