Quick answer
A letter of credit is a bank undertaking to pay a seller or beneficiary when the required documents comply with the credit terms. In practice, payment depends less on the physical goods and more on whether the document package matches the LC, UCP 600 / ISBP practice, and the bank’s examination requirements.
How a letter of credit works
- Buyer and seller agree to LC payment. The sales contract calls for payment by letter of credit.
- The buyer applies for the LC. The issuing bank opens the credit and sends it through banking channels.
- The seller reviews the LC before shipment. This is the best time to catch impossible document terms, tight timing, or mismatched commercial details.
- The seller ships and prepares documents. The document pack is built around the LC requirements.
- The bank examines the presentation. If the documents comply, the bank honors according to the credit terms. If not, a refusal/discrepancy cycle can begin.
Common documents in a letter of credit package
| Document | What to check |
|---|---|
| Commercial invoice | Goods description, amount, currency, Incoterms, party names, LC reference. |
| Bill of lading / transport document | Consignee, notify party, ports, on-board date, freight terms, transshipment, partial shipment. |
| Insurance certificate | Coverage amount, currency, risks, issuer, effective date, shipment references. |
| Packing list | Package count, weights, marks, quantities, goods consistency. |
| Certificate of origin / other certificates | Issuer, signature, origin wording, dates, product language, required statements. |
Common mistakes that create LC problems
- Invoice goods description does not follow the LC closely enough.
- Bill of lading names the wrong consignee or omits required on-board wording.
- Shipment happens after the latest shipment date or presentation timing is misread.
- Insurance coverage is below the required percentage or in the wrong currency.
- Certificates use party names, dates, or origin wording that conflict with the LC package.
- Amendments are missed, so documents are prepared against old LC terms.
