Description DLC is the most widely used instrument in international trade to mitigate financial risk, especially, in a higher amount of transactions. It protects both seller and buyer; the seller gets the payment and the buyer gets the goods. DLC is issued by a financial organization on request of the buyer, providing payment assurance to the seller once all the terms of the agreement are met.
