Letters of Credit Explained: A Practical Guide for GCC Importers

What a Letter of Credit Actually Does (and Why It Matters)

A letter of credit (LC) is a written commitment from your bank to pay your overseas supplier — provided the supplier presents a precise set of shipping and trade documents within a defined timeframe. It is not a loan, a guarantee of goods quality, or a blank cheque. It is a conditional payment promise, and that condition is documentary compliance — nothing more.

For a GCC importer sourcing electronics from Shenzhen, textiles from Istanbul, or industrial equipment from Germany, an LC solves one fundamental problem: your supplier does not trust you enough to ship on open account, and you do not trust them enough to pay 100% upfront. The LC sits between both parties and makes the deal possible.

Understanding how LCs work is not optional knowledge for an active importer. It is survival knowledge.

The Four Parties Every Importer Must Know

Most importers know two parties: themselves and their supplier. An LC involves four.

• Applicant — you, the importer. You instruct your bank to open the LC.
• Issuing Bank — your bank in the UAE, Saudi Arabia, or wherever you are domiciled. It creates and issues the LC.
• Beneficiary — your supplier (the exporter). They receive and draw on the LC.
• Advising / Confirming Bank — a bank in the supplier's country that advises them of the LC's existence. If it also confirms the LC, it adds its own payment undertaking on top of your issuing bank's promise.

Why Confirmation Changes the Deal

A supplier in a country where your issuing bank is unknown will often demand LC confirmation. An A-rated international bank in their country adds its guarantee to the instrument. This removes the supplier's country-risk concern about your bank — and typically lets you negotiate better payment terms in return. Confirmation carries a fee, usually paid by the applicant (you), and is worth every dirham when it unlocks a better price or longer payment terms.

The LC Lifecycle: Step by Step

Knowing the sequence prevents most mistakes.

1. Commercial Agreement

Before any bank is involved, you and your supplier agree on: price, currency, Incoterms (e.g. CIF Dubai or FOB Shenzhen), shipment deadline, and the exact documents required. These terms become your LC. Agree loosely, and your LC will be loose — and dangerous.

2. LC Application

You submit an LC application form to your issuing bank, alongside the relevant facility documentation. The bank charges an issuance commission (typically 0.1%–0.5% of LC value per quarter, depending on your credit relationship and the tenor).

3. Issuance and Transmission

Your bank issues the LC and transmits it — almost always via SWIFT MT700 — to the advising bank in the supplier's country. The supplier receives the LC text through their bank.

4. Supplier Ships and Presents Documents

The supplier ships the goods and gathers the required documents: commercial invoice, bill of lading or airway bill, packing list, certificate of origin, insurance certificate, and any inspection certificates specified in the LC. They present these to the advising/confirming bank within the stipulated presentation period (typically 21 days from shipment, but the LC controls this).

5. Document Examination

The banks examine documents against the LC terms. Under UCP 600 (the global ruleset governing LCs), they have five banking days to accept or reject. This is where discrepancies emerge.

6. Payment

If documents are compliant, the issuing bank pays. Payment timing depends on the LC type:

• Sight LC: payment on presentation of compliant documents — typically within 5 banking days.
• Usance (Deferred) LC: payment at a fixed future date — 30, 60, 90, or 180 days after sight or shipment. This is effectively supplier-extended credit to you.

Discrepancies: The Silent Profit Killer

Industry experience shows that 60–70% of first-presented LC document sets contain at least one discrepancy. Each discrepancy triggers a fee from the presenting bank (often USD 75–150 per discrepancy), delays payment to your supplier, and creates friction in your supply chain.

Common discrepancies GCC importers encounter:

• Stale bill of lading — documents presented after the 21-day presentation window.
• Description mismatch — invoice says "LED Display Panel 55 inch" but LC says "55-inch LED Monitor Panel."
• Late shipment — vessel departed after the latest shipment date in the LC.
• Unsigned or incomplete documents — a packing list missing the supplier's signature where the LC requires it.
• Wrong port — bill of lading shows Jebel Ali but LC specifies Port Rashid.

How to Minimise Discrepancies Before Issuance

The fix happens before the LC is issued, not after.

1. Share the draft LC text with your supplier before issuance and ask them to confirm they can comply with every clause.
2. Keep the document description in the LC exactly as it appears on your proforma invoice.
3. Set realistic shipment and presentation periods — do not allow only 10 days for a supplier to gather documents across three government agencies.
4. Specify Incoterms precisely: CIF Jebel Ali, UAE — not just "CIF Dubai."
5. Avoid requesting documents the supplier cannot realistically obtain (e.g. a certificate from a third-country authority with a 30-day lead time inside a 21-day presentation window).

The Real Cost of an LC: What to Budget

Importers often underestimate total LC cost. Here is a realistic breakdown for a USD 200,000 LC with 90-day usance tenor:

• Issuance commission: ~0.375% per quarter = USD 750
• Amendment fee (if needed): USD 50–100 per amendment
• Advising fee (charged by supplier's bank): USD 50–200 (sometimes passed to applicant by supplier)
• Confirmation fee: 0.5%–2.5% per annum depending on issuing bank country risk and tenor — on USD 200,000 for 90 days, budget roughly USD 250–1,250
• Discrepancy fees: USD 75–150 each — avoidable with preparation
• Acceptance commission (usance LCs): varies; typically 0.125%–0.25% per month on the deferred amount

Total cash cost for a well-structured USD 200,000 usance LC: roughly USD 1,000–2,500. Compare that to the cost of a failed shipment, a dispute, or 100% advance payment tied up for three months.

Choosing the Right LC Type for Your Trade

Not all LCs are equal. Matching the instrument to the deal structure matters.

Revocable vs. Irrevocable

All commercial LCs issued under UCP 600 are irrevocable by default. This means neither party can cancel or amend without the other's consent. Never accept a revocable LC — it offers you no real protection.

Sight vs. Usance

For cash-flow-conscious importers, a usance LC is a genuine working capital tool. A 90-day usance LC means you receive and potentially sell the goods before the payment date arrives. A Dubai electronics importer with a 90-day usance LC effectively gets supplier-funded inventory — provided they move product quickly enough.

Transferable LC

If you are a trading intermediary, a transferable LC lets you pass part of the instrument's value to your own upstream supplier. Useful for re-export structures but requires explicit "transferable" wording and careful structuring.

Standby LC

A standby LC functions more like a bank guarantee — it is called only if the applicant defaults. Commonly used in long-term supply contracts as performance security rather than payment mechanism.

Practical Considerations for GCC-Based SMEs

Most GCC banks will require a credit facility or cash margin to issue an LC on your behalf. For importers without an existing trade finance facility, this often means lodging 100% cash margin — effectively pre-paying from your own liquidity.

Building a trade finance facility takes time and a strong banking relationship. If your current bank is slow to move or requires excessive margin, exploring alternatives through LC confirmation and discounting specialists can help you access structured solutions through established banking relationships with tier-1 international institutions — subject to the approval, terms, and documentation requirements of the relevant licensed institution.

Always maintain a document checklist for every new trade lane. The documents required for a shipment from India differ from those from Turkey (certificate of origin formats, phytosanitary certificates, etc.). Standardise your internal process by lane, not by transaction.

Key Takeaways

• An LC is a conditional payment promise — compliance is documentary, not commercial.
• Know all four parties: applicant, issuing bank, beneficiary, advising/confirming bank.
• Discrepancies are common but preventable — share the draft LC with your supplier before issuance.
• Match LC type to your cash flow: usance LCs extend your payment window and protect working capital.
• Budget total LC costs including confirmation, acceptance commissions, and potential discrepancy fees — not just the issuance commission.
• If you lack a trade finance facility, your margin requirement ties up working capital; structured alternatives exist.

Your Next Step

If you are about to open your first LC, or if a recent discrepancy cost you time and money, start here: pull out your last or next proforma invoice, and write a draft LC clause by clause against it. Check every field — description, unit, port, Incoterms, latest shipment date, presentation period. If anything is ambiguous to you, it will be ambiguous to a bank examiner. Fix it before issuance, not after the ship has sailed.
