Irrevocable letter of credit

“A bank's promise to pay a seller against documents matching agreed terms, which cannot be cancelled or changed without the seller's agreement. Under the international rules most banks use (UCP 600), every letter of credit is irrevocable even if it does not say so.”

Why irrevocable letter of credit matters to a first-time founder

This instrument can reduce payment risk when buyer and seller are in different countries or lack an established relationship. Protection depends on exact documentary compliance and the issuing bank’s strength, not on whether the goods satisfy the buyer. Errors, sanctions or missed deadlines can still prevent payment.

Examples of irrevocable letter of credit

A UK exporter sells machinery for £120,000 to an overseas buyer. The buyer’s bank issues an irrevocable letter of credit requiring a commercial invoice, transport document and inspection certificate by set dates. The bank pays after compliant documents are presented, even though the buyer receives the shipment later.

Common misunderstanding

It is not a bank guarantee that every commercial problem will be solved. Banks examine documents rather than inspecting goods, and minor discrepancies can matter. “Irrevocable” limits unilateral cancellation but does not make the instrument immune to fraud, illegality, sanctions or changes agreed by the required parties.

When to use it

Consider one for high-value or cross-border trade where payment risk justifies bank fees and documentary work. Agree terms before shipment and have an experienced bank or trade adviser review them. Check governing rules, sanctions, expiry, presentation place, required documents and who pays each charge.
