Put simply, a Letter of Credit (LC) is an undertaking by a bank to make a payment to a named beneficiary within a specified time, against the presentation of documents which comply strictly with the terms of the Letter of Credit.

Its main advantage is providing security to both Buyer and Seller.

The Seller must understand the conditional nature of the Letter of Credit and the fact that payment will not be made unless the terms of the credit are met precisely.

A Letter of Credit is opened by a Buyer (applicant) to ensure that the documentation requested reflects and proves that the Seller has performed under the requirements of the underlying sales contract, by making them "conditions" of the Letter of Credit.

The sales contract is not an inherent part of the Letter of Credit, although the Letter of Credit may contain a reference to such contract).

For the Seller a letter of credit, apart from cash in advance, is the most secure method of payment in international trade as long as the terms are met.

The following diagram shows those involved in a Letter of Credit transaction:

When a Seller asks for payment by Letter of Credit, he is transferring the risk of non-payment by the Buyer to the Issuing Bank (and the confirming bank if the Letter of Credit is confirmed), providing the Seller presents the required documents in strict compliance with the Letter Of Credit. It is worth noting that over 50% of letters of credit are rejected on first presentation which can cause expensive delays for both the Seller and the Buyer. Up to one half of these rejections could have been avoided if more care was taken to ensure the letter of credit properly represented the sales contract.The use of a Draft Letter of Credit (DLC) is a very low cost, convenient way to move the buying process along without expensive delays. It is important to remember that all parties in the Letter of Credit transaction deal with documents, and not the actual physical commodities themselves.

Following is a list of the types of Letters Of Credit commonly used. It is important to note that Proimex uses a combination to protect all parties and is commonly called an "Irrevocable Transferable and Confirmed Revolving Letter Of Credit" as you read thru the letter of credit definitions you will soon understand why this is one of the safest instruments to use.

IRREVOCABLE
An irrevocable letter of credit can neither be amended nor cancelled without the agreement of all parties to the credit. Under UCP500 all letter of credit are deemed to be irrevocable unless otherwise stated. Here, the importer's bank gives a binding undertaking to the supplier provided all the terms and conditions of the credit are fulfilled.

UNCONFIRMED
An unconfirmed letter of credit is forwarded by the advising bank directly to the exporter without adding its own undertaking to make payment or accept responsibility for payment at a future date, but confirming its authenticity.

CONFIRMED
A confirmed letter of credit is one in which the advising bank, on the instructions of the issuing bank, has added a confirmation that payment will be made as long as compliant documents are presented. This commitment holds even if the issuing bank or the buyer fails to make payment. The added security to the exporter of confirmation needs to be considered in the context of the standing of the issuing bank and the current political and economic state of the importer's country. A bank will make an additional charge for confirming a letter of credit.

Confirmation costs will vary according to the country involved, but for many countries considered a high risk will be between 2%-8%. There also may be countries issuing letter of credit which banks do not wish to confirm – they may already have enough exposure in that market or not wish to expose themselves to that particular risk at all.

STANDBY LETTER OF CREDIT
A standby letter of credit is used as support where an alternative, less secure, method of payment has been agreed. They are also used in the United States of America in place of bank guarantees. Should the exporter fail to receive payment from the importer he may claim under the standby letter of credit. Certain documents are likely to be required to obtain payment including: the standby letter of credit itself; a sight draft for the amount due; a copy of the unpaid invoice; proof of dispatch and a signed declaration from the beneficiary stating that payment has not been received by the due date and therefore reimbursement is claimed by letter of credit. The International Chamber of Commerce publishes rules for operating standby letter of credit – ISP98 International Standby Practices.

REVOLVING LETTER OF CREDIT
The revolving credit is used for regular shipments of the same commodity to the same importer. It can revolve in relation to time or value. If the credit is time revolving once utilized it is re-instated for further regular shipments until the credit is fully drawn. If the credit revolves in relation to value once utilized and paid the value can be reinstated for further drawings. The credit must state that it is a revolving letter of credit and it may revolve either automatically or subject to certain provisions. Revolving letters of credit are useful to avoid the need for repetitious arrangements for opening or amending letters of credit.

TRANSFERABLE LETTER OF CREDIT
A transferable letter of credit is one in which the exporter has the right to request the paying, or negotiating bank to make either part, or all, of the credit value available to one or more third parties.

BACK-TO-BACK LETTER OF CREDIT
A back-to-back letter of credit can be used as an alternative to the transferable letter of credit. Rather than transferring the original letter of credit to the supplier, once the letter of credit is received by the exporter from the opening bank, that letter of credit is used as security to establish a second letter of credit drawn on the exporter in favor of his importer. Many banks are reluctant to issue back-to-back letters of credit due to the level of risk to which they are exposed, whereas a transferable credit will not expose them to higher risk than under the original credit.

UNIFORM CUSTOMS AND PRACTICE FOR DOCUMENTARY CREDITS (UCP)
Most letters of credit are subject to UCP 500, which are the universally recognized set of rules governing the use of the documentary credits, in international trade. UCP were originally formulated in 1933 by the International Chamber of Commerce (ICC) and last updated in 1993 (ICC publication 500). All definitions and general documentary requirements referred to in this briefing are in accordance with UCP500 unless otherwise stated (it should be remembered that in some instances this may differ from national law). Proimex Pty Ltd would only recommend using letters of credit which are subject to UCP500.

IMPORTANT NOTE
For all buyers/suppliers who are seeking to enter into a Supply 'Contract' arrangement over a period of months.

If you would like to purchase a large quantity of a certain commodity, and have it delivered over a series of shipments, it is essential that you establish a Revolving L/C facility as your method of payment.

Example: How to BUY your commodities cheaper by committing to volumes.

You would like to purchase 1,000,000MT of Corn and have it delivered in lots of 100,000MT over a 10 month period.

The price for 1,000,000MT is $300 USD CIF, compared with the price of $425 USD CIF for 100,000MT

If you would like to pay the lower price of $300USD CIF, you will have to enter into a contract for the 10 months period and establish a “Revolving L/C” facility to cover the 10 L/Cs that will be required for the transaction.
