Letter of Credit (L/C) remains one of the most secure payment methods for high-value international B2B transactions, particularly for Southeast Asian exporters selling on Alibaba.com. An L/C is a bank's irrevocable undertaking to pay the seller when specified conditions and documents are presented, effectively transferring payment risk from the buyer-seller relationship to the banking system [1].
For sellers in the Other Apparel category (which includes diverse products from electronics accessories to religious vestments), understanding L/C mechanics is crucial when dealing with high-value orders. The instrument is governed by UCP 600 (Uniform Customs and Practice for Documentary Credits), internationally recognized rules adopted by banks in over 175 countries [1]. This standardization provides a common framework that protects both exporters and importers across different legal jurisdictions.
The L/C workflow involves multiple parties: the applicant (buyer), the beneficiary (seller), the issuing bank (buyer's bank), and often an advising or confirming bank (seller's bank). When a buyer opens an L/C, their bank commits to paying the seller upon presentation of compliant documents—typically including commercial invoice, packing list, bills of lading, and insurance certificate [4]. This document-based payment system ensures sellers receive payment once they prove shipment, while buyers know payment only occurs if terms are met.
"LC is an undertaking by the buyer's bank to pay suppliers subject to agreed conditions. It provides payment security for both exporters and importers, and can facilitate working capital finance." [4]
