What is a Letter of Credit and what key terms protect both buyer and seller in maritime trade?

• A. A bank's undertaking to pay if documents comply; key terms include documentary requirements, expiry, endorsements, and dispute resolution provisions.
• B. A contract for sale between buyer and seller.
• C. An insurance certificate guaranteeing shipment.
• D. A bill of lading issued by a bank with no document requirements.

Answer: (A)

A Letter of Credit is a bank’s promise to pay the seller, provided the seller presents documents that strictly meet the terms of the credit. In maritime trade this arrangement gives both sides confidence: the seller is paid as long as they ship and provide the specified documents, while the buyer pays only against compliant documents, not merely against a shipment.

The key terms that protect both parties include the documentary requirements, which spell out exactly which documents must be presented (such as a commercial invoice, a clean bill of lading, packing list, and any certificates). This ensures payment is tied to verifiable evidence of shipment and contract compliance, reducing the risk of paying for non-shipped or non-conforming goods. The expiry or validity period sets a clear deadline for presenting documents, preventing endless payment obligations. Endorsements or transferability terms determine who can claim payment or transfer rights under the credit, which helps manage risk if the seller assigns the credit. Dispute resolution provisions establish how any disagreements about documents or terms will be handled, providing a structured path to resolve issues without immediate default.

These elements together distinguish a Letter of Credit from the other options: it is not merely a contract for sale, nor an insurance certificate, and it is not a bill of lading issued by a bank. The bank’s role and the requirement for documentary compliance are what give the instrument its protective, trade-financing function.
