Credit Letter: Types of Letter of Credit (With Example)

A letter of credit is a communication from a buyer’s bank to guarantee a supplier payment for goods supplied or services rendered. The letter is mostly used in international trade as a surety that a supplier will receive payment. When the buyer isn’t able to pay in time, their bank must make the payment. These letters have gained popularity because of several factors that govern international trade such as distance and trade laws in different countries.

If faced with a challenge when writing these letters, you can use samples and templates to familiarize yourself on the details and format.

Types of letter of credit

Based on business transactions, various kinds of letters of credit exist. Most common letters of credit include;

Transferable LC

A beneficiary can write a letter to transfer payment to another beneficiary or supplier; this letter is a transferable LC. The beneficiary is a link between a seller and the actual supplier. In such a case, the recipient can use their documents as they transfer the money.

UN-transferable LC

The letter doesn’t allow transfer of payment to third parties. It’s only the beneficiary who can claim payment using this letter.

Standby LC

The letter acts as a guarantee for payment. If the buyer does not pay the seller, the bank has to honor the letter by paying the seller.

Revocable LC

A revocable letter of credit is a credit letter the issuing bank or the buyer can cancel that without notifying the seller. Such letters are not common since the seller has no guarantee of payment with this letter.

Irrevocable LC

Any changes to this letter can only be made after consultations between the involved parties. This letter guarantees the seller of payment.

Back to Back LC

We use this letter of credit in transactions that involve an intermediary. Back to Back LC involves two letters; one to the intermediary by the buyer’s bank and a second letter to the supplier by the intermediary’s bank.

Confirmed LC

A second bank writes a confirmed letter of credit to guarantee payment to the seller. The letter cushions the seller from non-payment by the buyer’s bank thus the need for a letter from a second bank confirming payment.

Non-Confirmed LC

This letter of credit is issued by the buyer’s bank and doesn’t include assurance for payment from a second bank. Most letters of credit fall under this category.

Export/import LC

The letter of credit can either be referred to as export or import LC depending on whether an importer or exporter uses it.

Commercial LC

A commercial letter of credit is the standard LC and can also be referred to as a documentary credit.

Revolving LC

If a single letter of credit is used to cover several transactions, it’s referred to as a revolving letter of credit. Additionally, we can classify revolving credit letters as either value based or time-based.

Deferred payment LC

It’s a credit letter that gives an assurance to the buyer they will receive payment in a stated period. It’s important to note the bank can make payments before the agreed time.

Green clause LC

The letter of credit allows an advance payment of the seller against a receipt, the written undertaking, and proof that the seller has warehoused the goods.

Red clause LC

It’s a credit letter that allows partial payment of the seller even before they ship the goods or offer services.

Direct pay LC

It’s a letter of credit that enables the bank to pay the seller directly and recover the money from the buyer.

Sight LC

It’s a letter of credit that allows the issuing bank to pay the seller if they present the relevant documents as spelled out in the letter.
