When dealing with high-volume sewing machine orders—particularly those exceeding 20 tons or significant monetary values—payment security becomes a paramount concern for both buyers and sellers. Letter of Credit (L/C) is one of the most widely used payment mechanisms in international B2B trade, offering bank-backed guarantees that protect both parties throughout the transaction process.
What is a Letter of Credit? An L/C is a contractual commitment issued by a buyer's bank (the issuing bank) guaranteeing payment to the seller (exporter) upon presentation of specified documents that comply with the terms and conditions outlined in the credit. This instrument is governed by the Uniform Customs and Practice for Documentary Credits (UCP 600), which is recognized in 175 countries worldwide [4].
How L/C Works in Practice: The process begins when the buyer applies for an L/C at their bank. Once issued, the seller ships the goods and presents required documentation (commercial invoice, bill of lading, packing list, certificate of origin, etc.) to their bank. If documents comply with L/C terms, payment is released. This mechanism shifts payment risk from the seller to the bank, providing significant security for high-value transactions.
"Documentary LC is common in Asia. Standby LC is common in Europe and Latin America. Many US companies refuse to deal with LC at all. Transaction value is typically over $1 million." [2]
