Letters of credit still matter in 2026 because cross-border sales fail in ordinary ways. A buyer is new. Country risk changes fast. Credit information is thin. The U.S. International Trade Administration's methods-of-payment guide still places letters of credit in the middle ground between open-account flexibility and cash-in-advance caution. They are slower than a simple bank transfer, but a lot safer when trust is not settled yet.
If you are structuring a new supply lane, keep the payment file tied to the customs and logistics file. Corpenza's import-export business guide, import duties guide, and import-export advisory desk help when payment terms, landed cost, and supplier risk need to be read together. That is usually where deals either become bankable or start leaking margin.
What is a letter of credit in international trade?
A letter of credit in international trade is a bank commitment to pay the exporter once shipment has been made and the required documents are presented correctly. The Trade.gov letter-of-credit page says the foreign buyer's bank pays after the exporter ships the goods and presents the required documentation to the exporter's bank as proof.
That point matters more than the label. A letter of credit is not a promise that the cargo is perfect. It is a document-driven payment mechanism. If the credit calls for a commercial invoice, transport document, packing list, or insurance certificate, the bank cares about whether those documents comply with the credit terms. A clean file moves. A sloppy one stalls.
When should an exporter ask for a letter of credit?
An exporter should usually ask for a letter of credit when the buyer is new, the market is higher risk, reliable buyer-credit information is hard to get, or the buyer wants extended payment terms. Trade.gov describes letters of credit as one of the most secure payment instruments available and recommends them for higher-risk situations and newer trade relationships.
This is where commercial judgment comes in. If the buyer is established, repeat volumes are steady, and claims history is clean, a full letter-of-credit structure can feel too heavy. But on a first order, or on a shipment large enough to hurt if it goes wrong, the extra bank process can be cheap insurance. Many founders learn that only after one bad collection cycle.
Which documents do banks usually check under a letter of credit?
Banks check the documents named in the credit, not a vague story about the shipment. The official Trade.gov guidance on letters of credit stresses that payment follows only when the exporter presents the required documentation as proof. In practice, the document list often includes the commercial invoice, transport document, packing details, and any inspection or insurance paper written into the credit.
That is why the sales contract and the credit application cannot be drafted in isolation. If the purchase contract says one thing, the freight forwarder issues a slightly different transport document, and the bank credit repeats the mismatch, you have created delay before the goods even move. Small wording gaps do real damage here. Date formats, consignee names, partial-shipment rules, and Incoterm references all need one version of the truth.
What causes payment delays most often under a letter of credit?
The most common cause of delay is not fraud. It is discrepancy. Trade.gov says the required documents are detailed and prone to errors and discrepancies, and that those mistakes can trigger payment delays and extra fees. A credit can be approved by every party in principle and still fail in execution because the file is inconsistent.
Most discrepancies are painfully ordinary. A shipment date falls outside the allowed window. The invoice description does not mirror the credit text. The bill of lading is issued in a slightly different name. A document is missing one signature. None of that sounds dramatic. It still slows payment, and sometimes it shifts bargaining power back to the buyer at exactly the wrong moment.
How is documentary collection different from a letter of credit?
Documentary collection is lighter and usually cheaper, but it does not give the exporter the same bank-payment commitment. The Trade.gov documentary-collections page says the importer’s bank releases documents either after payment or after signed acceptance of future payment. The same methods-of-payment guide says documentary collections offer no verification process and limited recourse if the importer does not pay.
That makes documentary collection useful for cleaner buyer relationships, not as a universal substitute for letters of credit. If the importer refuses to pay, Trade.gov notes that the exporter may need to find another buyer, pay return freight, or abandon the merchandise. That is a very different risk profile.
| Method | Bank role | Exporter risk | Typical fit |
|---|---|---|---|
| Letter of credit | Bank gives a payment commitment against compliant documents | Lower, if the file is compliant | New buyer, larger order, higher-risk market |
| Documentary collection | Bank passes documents and collects payment instructions | Higher than LC, with limited recourse | Repeat buyer, lower friction, cost-sensitive shipment |
Who should pay bank charges and what should the contract say?
Bank charges should never be left to habit or assumption. The contract and the credit request should state clearly which side pays issuance, advising, confirmation, amendment, discrepancy, and reimbursement charges. If that is left vague, the payment instrument works mechanically but the deal economics still drift.
Keep the clause plain. Say which bank charges belong to the buyer, which costs fall outside the seller’s country, whether confirmation is mandatory, and who pays if the buyer asks for amendments after issuance. Then check that the credit itself reflects the same allocation.

Frequently asked questions
Does a letter of credit guarantee that the goods are good?
No. It is a document-based payment commitment. The bank checks compliance with the credit documents, not the commercial quality of the cargo itself.
Are letters of credit still useful for small shipments?
Sometimes, yes. But bank fees and admin can outweigh the benefit on smaller or very routine orders. The risk and ticket size need to justify the structure.
When is documentary collection a better fit?
Usually when the buyer relationship is already working, the exporter can tolerate more payment risk, and both sides want lower banking friction than a letter of credit.
Can a clean deal still get delayed under a letter of credit?
Yes. Document discrepancies are the classic reason. A good buyer and good goods do not fix a non-compliant paper set.
What should be aligned before the credit is issued?
The sales contract, Incoterm, shipment window, document list, consignee details, and fee allocation should all say the same thing before the bank instrument is opened.
This is general information, not legal, tax, or trade-finance advice. The right payment method depends on shipment size, buyer risk, country risk, and the exact contract terms.
