How a commercial documentary credit works
The buyer arranges for an issuing bank to issue the credit in favor of the seller. The seller reviews the terms and presents the required documents within the permitted dates and presentation process.
Payment may be at sight or at a future maturity, depending on the credit. A buyer's default is not a universal prerequisite for payment under a commercial LC.
Documents and bank roles
Where UCP 600 applies, banks deal with documents rather than the underlying goods or performance. A compliant presentation does not certify the quality of the shipment.
An advising bank communicates the credit. A confirming bank adds its own undertaking when it confirms the credit; advising and confirming are distinct roles.
Commercial versus standby
A commercial LC can be the agreed payment method for the transaction. A standby LC generally supports an obligation if the applicant fails to perform or pay, subject to the standby's documentary requirements.
Do not describe every LC claim as liquidation triggered by insolvency.
Practical checks
Review the issuing bank, currency, expiry, presentation location, required documents, payment timing, discrepancies, and applicable rules. Fees, financing availability, and residual bank or country risks vary.
An LC is not a guarantee against every commercial, currency, or political risk.
