Letter of Credit (L/C)

Letter of Credit (L/C)

Letter of Credit (L/C) is a financial instrument issued by a bank at the request of the buyer. It serves as a guarantee that the seller will receive payment, provided that the terms and conditions specified in the L/C are met.

Unlike T/T, which relies on the trust between two trading parties, an L/C shifts the credit risk from the buyer to the bank. It is widely considered the most secure method of payment for international trade, particularly when dealing with new suppliers or high-value shipments where the risk of non-performance is high.


What Is L/C Meaning in Shipping?

An L/C is essentially a bank's commitment to pay. The seller is only entitled to payment if they can present a specific set of documents (e.g., Bill of Lading, Commercial Invoice, Packing List, Certificate of Origin) to the bank, proving that the goods have been shipped exactly as stipulated in the contract.

Example Scenario: Imagine you are importing high-precision machinery worth $150,000 from a manufacturer in Hamburg, Germany, to your facility in New York, USA. Because this is a high-stakes transaction, you utilize an L/C:

  1. Opening the L/C: You instruct your bank (the Issuing Bank) to open an L/C in favor of the German manufacturer.
  2. Notification: The Issuing Bank sends the L/C to the manufacturer's bank in Germany (the Advising Bank).
  3. Shipment: The German manufacturer ships the machinery and prepares the required documents.
  4. Presentation: The manufacturer submits these documents to their bank, which verifies they comply with the L/C terms.
  5. Payment: The manufacturer's bank forwards the documents to your bank, which then releases the payment to the seller. You, in turn, receive the documents necessary to clear the goods through U.S. customs.

When Should You Use L/C?

  • High-Value Transactions: When the capital at risk is significant ($50,000+), the bank fees for an L/C are a small price to pay for security.
  • New International Partnerships: When you lack a history of trust with a supplier, an L/C ensures they cannot collect payment without documented proof of shipment.
  • Complex Regulatory Requirements: If your import requires strict documentation for government compliance, an L/C ensures the seller provides every required paper before the money is released.


Essential Considerations & Warnings

  • The "Discrepancy" Trap: L/Cs are document-centric, not goods-centric. If your Bill of Lading has a typo or the invoice is missing a comma, the bank can classify this as a "discrepancy" and refuse to pay. Sellers often charge extra for the administrative burden of L/C compliance.
  • High Costs: L/Cs are the most expensive payment method due to bank issuance fees, advising fees, and confirmation fees. They are rarely cost-effective for small, recurring orders.
  • Strict Adherence: The terms in an L/C must be absolute. If you ask for a shipment date of "March 15th" and the seller ships on "March 16th," the bank is legally obligated to reject the documents. Ensure your contract terms are realistic before opening an L/C.
  • Irrevocable vs. Revocable: Always ensure your L/C is "Irrevocable," meaning it cannot be cancelled or changed by the buyer without the seller's consent. Revocable L/Cs offer almost no protection to the seller.
