Understanding Irrevocable LC

Most Letters of Credit used in international trade today are irrevocable by default, but understanding exactly what that guarantees — and what it doesn't — helps exporters avoid unpleasant surprises.

What 'irrevocable' actually means

An irrevocable LC cannot be amended or cancelled by the issuing bank or the buyer without the consent of all parties, including the beneficiary (the exporter). This protects the exporter from the buyer unilaterally withdrawing or changing terms after the LC is issued.

Irrevocable does not mean risk-free: the issuing bank's undertaking to pay is still conditional on the exporter presenting documents that comply exactly with the LC's terms.

Irrevocable vs confirmed

An irrevocable LC relies on the creditworthiness of the issuing bank, which may be in a jurisdiction or of a standing the exporter is unfamiliar with. A confirmed LC adds a second bank (often in the exporter's own country) that independently undertakes to pay, providing an additional layer of protection where the issuing bank's risk is a concern.

What to check before accepting LC terms

Review the LC for workable shipment and presentation deadlines, correct spelling of company names and product descriptions, achievable documentary requirements, and consistency with the underlying sales contract — before production begins, not after.

See the LC Document Verification Protocol for a structured approach to checking draft and issued LCs against UCP 600 and the underlying order.

Key Takeaways

Irrevocable protects against unilateral cancellation or amendment, but payment still depends on exact document compliance.
A confirmed LC adds a second bank's payment undertaking, useful when the issuing bank's standing is uncertain.
Review LC terms for workable dates and achievable documentary requirements before production begins, not at presentation.

FAQ

Should I always ask for a confirmed LC?

Not necessarily — confirmation adds cost. It is most relevant when the issuing bank's country or standing raises genuine payment-risk concerns. Discuss with your own bank whether confirmation is warranted for a specific transaction.

Can an irrevocable LC still fail to pay?

Yes — if the documents presented do not strictly comply with the LC's terms, the issuing bank can refuse payment on that basis, irrespective of the LC being irrevocable. Document accuracy is critical.
