Types of letters of credit (UCP 600): sight, usance, confirmed, transferable
A letter of credit is described by how and where it is paid, and by who stands behind it. Under the ICC's UCP 600 every credit is irrevocable, must say whether it is available by sight payment, deferred payment, acceptance or negotiation, and may be confirmed by a second bank or made transferable to another beneficiary.

How a credit can be paid (Article 6(b))
- Sight payment: the bank pays when it receives complying documents.
- Deferred payment: the bank undertakes to pay at a later date, for example 90 days after shipment, without a bill of exchange.
- Acceptance: the bank accepts a bill of exchange (draft) drawn by the beneficiary and pays it at maturity.
- Negotiation: a nominated bank purchases the drafts or documents, advancing funds to the beneficiary before the issuing bank reimburses it.
Confirmed credits
A confirmation is a second, independent undertaking added by another bank, usually in the beneficiary's country. Under Article 8 the confirming bank is irrevocably bound to honour or negotiate as soon as it adds its confirmation, provided complying documents are presented to it or to another nominated bank. Exporters ask for confirmation when they are unsure of the issuing bank or of the country risk.
Transferable credits
A trading company that buys from a supplier and sells to the final buyer can ask for a transferable credit. Under Article 38 only a credit that specifically states it is "transferable" can be made available, in whole or in part, to a second beneficiary at the first beneficiary's request, and the transferring bank need only do so to the extent and in the manner it expressly agrees. A transferred credit cannot be transferred again at the request of the second beneficiary. Standby letters of credit, which act as guarantees, are covered in a separate note.
Step by step
- Agree in the sales contract which type of credit and which availability (sight, deferred, acceptance or negotiation) you need.
- Ask for confirmation by a bank you trust if the issuing bank or country is a risk.
- If you are an intermediary, ask for the word "transferable" in the credit.
- Check the expiry date and place, and plan to present within 21 calendar days after shipment.
- Prepare documents that comply exactly with the credit.
- Expect the bank's decision within five banking days after presentation.
Documents you usually need
- Letter of credit and amendments
- Bill of exchange (draft), when the credit requires one
- Commercial invoice
- Transport document
- Other documents the credit lists
