The Documentary Credit: How to Secure International Trade Payments

A documentary credit is one of the most effective ways to secure payment in international trade, provided that the banks are reliable, the terms are properly negotiated and the documents presented comply with the credit.

For a Credit Manager, the key question is not simply whether a documentary credit exists. It is whether its terms genuinely protect the exporter and can be fulfilled in practice.

What is a documentary credit?

A documentary credit (often called a letter of credit or LC) is an undertaking by an issuing bank to honour a complying presentation of documents under the terms of the credit. It is commonly used in international trade to reconcile the exporter’s need for payment security with the importer’s wish to pay against evidence of shipment or other agreed documentary conditions.

Most modern commercial documentary credits are subject to the Uniform Customs and Practice for Documentary Credits (UCP 600), published by the International Chamber of Commerce, when expressly incorporated into the credit.

Fundamental principle: banks deal with documents, not with the goods or services themselves. A compliant document presentation does not prove that goods are free from defects. Equally, a commercial dispute does not automatically relieve a bank of its independent undertaking.

Documentary credits are independent of the underlying sales contract. This separation is essential: the seller must meet the documentary requirements even when the commercial transaction has otherwise been performed correctly.

Who is involved?

Participant	Role
Applicant	The buyer or importer who requests issuance of the credit.
Issuing bank	The buyer’s bank, which undertakes to honour a complying presentation.
Beneficiary	The seller or exporter in whose favour the credit is issued.
Advising bank	Authenticates and advises the credit to the beneficiary, without automatically undertaking to pay.
Confirming bank	Adds its own independent undertaking to honour or negotiate a complying presentation, when it agrees to confirm the credit.

The advising bank and confirming bank may be the same institution, but advising a credit is not the same as confirming it.

Advised or confirmed: which level of protection?

Under UCP 600, a documentary credit is irrevocable even if it does not expressly say so. A credit cannot normally be amended or cancelled without the agreement of the issuing bank, any confirming bank and the beneficiary. The old distinction between revocable and irrevocable documentary credits should not be presented as three current standard categories.

Structure	Bank commitment	Main consideration for the exporter
Irrevocable, advised but unconfirmed	The issuing bank is committed; the advising bank does not add a payment undertaking.	Assess the issuing bank and the country in which payment must be made.
Irrevocable and confirmed	The confirming bank adds its own undertaking, subject to a complying presentation.	Reduces dependence on the issuing bank and may mitigate certain country and transfer risks, subject to the confirmation’s terms.

A confirmed documentary credit is often preferable when the issuing bank’s credit quality, political environment or transfer restrictions raise concerns. However, confirmation does not protect the seller against its own documentary discrepancies or every possible legal or sanctions-related obstacle.

How does a documentary credit work?

Commercial agreement. Buyer and seller agree on a documentary credit and negotiate its key terms before shipment.
Application. The buyer asks its bank to issue the credit, specifying the amount, expiry, shipment deadlines and required documents.
Issuance. The issuing bank transmits the credit, usually through authenticated banking channels.
Advice and possible confirmation. The seller’s bank advises the credit and may add confirmation if requested and accepted.
Review before shipment. The exporter checks that every condition is achievable and requests amendments where necessary.
Shipment and document preparation. The seller ships the goods and prepares the stipulated documents.
Presentation. Documents are presented to the nominated or confirming bank, or as otherwise required by the credit, within the applicable deadlines.
Examination. The relevant banks examine the presentation against the credit, UCP 600 and applicable international standard banking practice.
Honour or negotiation. A complying presentation is honoured or negotiated according to the credit’s availability and payment terms.
Release of documents. The issuing bank makes documents available to the buyer under its arrangements with the applicant.

Operational warning: even a minor discrepancy can delay payment, trigger a request for waiver or lead to refusal. Under UCP 600, banks generally have a maximum of five banking days following the day of presentation to determine whether a presentation complies.

When does the exporter receive payment?

A documentary credit may be available by:

Sight payment: payment following a complying presentation and the bank’s examination.
Deferred payment: payment at a specified future maturity, such as 90 days after a defined event.
Acceptance: the bank accepts a qualifying bill of exchange and pays at maturity.
Negotiation: an authorised bank purchases drafts and/or documents under a complying presentation, in accordance with the credit’s terms.

Deferred-payment and acceptance credits can sometimes be financed or discounted, depending on the bank, the transaction and the applicable terms. There is no universal two-to-seven-day payment guarantee: timing depends on presentation, examination, availability, maturity and banking arrangements.

How to negotiate a documentary credit effectively

The most important work takes place before the goods are shipped. The Credit Manager should review the draft credit alongside sales, logistics and the banking partner.

Item to verify	Practical question
Issuing bank and confirmation	Is the issuing bank acceptable? Is confirmation needed, available and correctly worded?
Amount and currency	Does the credit cover the agreed price, currency and any permitted tolerances?
Expiry and presentation period	Is there enough time to ship, obtain documents and present them?
Shipment conditions	Are partial shipments, transhipment and the latest shipment date compatible with operations?
Required documents	Can the exporter obtain each document in exactly the required form?
Incoterm	Is the agreed Incoterm consistent with the transport, insurance and documentary requirements?
Payment availability	Is payment at sight or deferred? Which bank is nominated to honour or negotiate?
Bank charges	Who pays issuance, confirmation, amendment and discrepancy fees?

Critical negotiating point: avoid making payment depend on a document that only the buyer can issue or approve after shipment, such as an unrestricted buyer-signed acceptance certificate. Otherwise, the buyer may effectively control whether the exporter can make a complying presentation.

For example, a seller may deliver goods correctly but remain unable to present documents if the credit requires a buyer-issued certificate that the buyer refuses to sign. The documentary credit then offers much less practical security than expected.

Remember that the sales contract, documentary credit and transport arrangements are legally distinct, even though they must be operationally consistent.

What does a documentary credit cost?

Costs can include issuance, advising, confirmation, amendment, document examination, negotiation and discrepancy fees. Confirmation pricing depends on the issuing bank, country risk, amount, tenor and market conditions. Rather than relying on a fixed percentage, obtain a transaction-specific quote and compare the cost with the credit exposure being secured.

Special structures

Transferable credit: a credit expressly designated as transferable may be transferred to one or more second beneficiaries under the conditions of UCP 600. It can help intermediaries finance purchases from their suppliers.

Back-to-back credit: a separate documentary credit is issued in favour of a supplier, supported commercially by an incoming credit. The two credits remain distinct undertakings, and the intermediary must manage differences in amounts, dates and documents.

The Credit Manager’s conclusion

A documentary credit can significantly reduce export payment risk, but its value lies in the quality of the bank commitments and the feasibility of the documentary conditions, not in the label alone.

Choose the issuing bank carefully, seek confirmation when justified, negotiate documents that your business can actually produce and check the credit before shipment. These decisions matter more than any generic claim that a documentary credit makes payment automatic.
