Irrevocable vs Confirmed Letter of Credit

An irrevocable letter of credit and a confirmed letter of credit get used almost interchangeably by exporters who have never actually needed the difference to matter. They are not the same protection, and conflating them is one of the more expensive assumptions you can make before signing a sales contract. The irrevocable vs confirmed letter of credit question comes down to one thing: who is actually on the hook to pay you, and what happens if that party can't or won't.
What an Irrevocable Letter of Credit Actually Protects You From
Since the 2007 revision of UCP 600, the rules that govern almost every letter of credit, a credit is irrevocable unless it explicitly says otherwise. Revocable letters of credit have more or less disappeared from real trade. 'Irrevocable' means the issuing bank, the buyer (the applicant) and you (the beneficiary) all have to agree before the credit's terms can be amended or cancelled. Your buyer cannot quietly ask their bank to change the payment amount, push out the shipment deadline, or withdraw the credit once you've already started production against it.
That is real protection against one specific risk: a buyer who gets cold feet, finds a cheaper supplier, or simply changes their mind partway through the deal. It is not protection against the issuing bank itself. If that bank is undercapitalised, based in a country that suddenly restricts outward transfers, or just slow and unresponsive, an irrevocable letter of credit does nothing to fix that. That's one half of the irrevocable vs confirmed letter of credit equation.
What 'Confirmed' Adds on Top of Irrevocable
A confirmed letter of credit brings in a second bank, the confirming bank, usually one in your own country or one you already trust. That bank adds its own independent promise to pay you once you present documents that comply with the credit's terms, in full. You're no longer relying on a single institution, possibly one you have never dealt with, sitting in a country you don't operate in and can't easily chase.
If the issuing bank fails, gets sanctioned, or its country blocks the transfer after your goods have already shipped, the confirming bank still has to pay you. Recovering that money from the issuing bank afterward becomes the confirming bank's fight, not yours. For an exporter shipping against a letter of credit from an unfamiliar bank, that second promise is often worth more than the fee it costs.
Irrevocable vs Confirmed Letter of Credit: Side by Side
The table below separates what each term actually guarantees. They solve different problems, and the added cost only applies to one of them.
| Irrevocable letter of credit | Confirmed letter of credit | |
|---|---|---|
| Who can cancel or change it | Nobody, unilaterally. Needs the issuing bank, the buyer and you to all agree. | Same rule, plus the confirming bank also has to agree once its promise is added. |
| Risk it removes | The buyer backing out or quietly changing terms mid-deal. | The issuing bank failing to pay, being sanctioned, or its country blocking the transfer. |
| Who is obligated to pay you | The issuing bank only. | The issuing bank and a second, confirming bank, independently of each other. |
| Typical added cost | None beyond standard LC charges. | A confirmation fee, roughly 0.5% to 2% of the credit's value. |
| Depends on the issuing bank's health | Yes, entirely. | No. The confirming bank pays even if the issuing bank can't. |
| Is it the default on most trade LCs today | Yes, since UCP 600 (2007). | No. It has to be specifically requested and priced in. |
When a Confirmed Letter of Credit Is Worth the Extra Cost
The irrevocable vs confirmed letter of credit question usually comes down to how much you trust the issuing bank and the country it sits in. Confirmation has a real cost, so it's worth asking for when one or more of the following apply:
- The issuing bank doesn't appear in the major credit-rating tiers, or you simply can't find reliable information on it
- The buyer's country has a history of foreign-exchange shortages, capital controls, or delayed outward remittances
- The shipment's value is large enough that a payment failure would hurt your business more than a confirmation fee would
- You have no prior payment history with this specific issuing bank, even if you've shipped to this buyer before
- Your own bank is actually willing to confirm it. Not every bank takes on every issuing bank's risk, and some cap the confirmed amount below the full credit value
Common Mistakes Exporters Make With LC Terms
The single most common mistake in the irrevocable vs confirmed letter of credit decision is treating the two words as synonyms, and only discovering the gap after the goods are already loaded. A buyer's proforma invoice might promise an 'irrevocable letter of credit' as if that alone settles the payment risk, when the real exposure sits with an issuing bank nobody on the seller's side has actually checked. Confirmation has to be negotiated and priced into the deal before the credit is opened, not requested afterward as an afterthought once a shipment is already committed.
We've covered how a standard letter of credit works end to end, from opening through document presentation and payment, in our Letter of Credit for Exporters guide, worth reading alongside this one if you're negotiating LC terms for the first time.
Getting the Terms Right Before You Ship
Settle confirmation at the sales contract or proforma invoice stage, before the buyer's bank issues anything. Asking for a confirmed letter of credit after the credit has already been opened unconfirmed means renegotiating terms your buyer has no obligation to accept. Get an indicative confirmation fee quote from your own bank early, so it's priced into your margin rather than discovered after the deal is already signed and the shipment date is fixed.
Both irrevocable and confirmed letters of credit are governed by UCP 600, the ICC's uniform rules for documentary credits, which is worth knowing in outline if LCs are a regular part of how you get paid. Trade.gov's overview of letters of credit is a reasonable starting point for the mechanics if your own bank's explanation leaves gaps.

Frequently asked questions
Is a confirmed letter of credit always irrevocable?
Yes. Under UCP 600 a confirming bank can only add its confirmation to a credit that's already irrevocable, so every confirmed letter of credit is automatically irrevocable too. The reverse isn't true: plenty of irrevocable letters of credit are never confirmed.
Who pays the confirmation fee on a confirmed letter of credit?
It's negotiable and should be settled in the sales contract before the credit is opened. Many buyers push it onto the seller as a standard cost of doing business, but an exporter facing real country risk can reasonably ask the buyer to cover it, or split it.
Can a bank refuse to confirm a letter of credit?
Yes. A confirming bank is taking on the issuing bank's credit risk as its own, so it can decline outright, ask for additional security, or set a confirmed limit lower than the full credit amount. Check with your bank before promising 'confirmed' terms in a contract.
What's the real difference between irrevocable vs confirmed letter of credit in an actual payment dispute?
With an irrevocable but unconfirmed letter of credit, you're relying entirely on the issuing bank's ability and willingness to pay; if it's slow, insolvent, or blocked by its own central bank, your recourse runs through that bank's home country. With a confirmed letter of credit, the confirming bank in your own country is independently obligated to pay once you present compliant documents, regardless of what happens to the issuing bank afterward.
Does confirmation protect against the buyer rejecting the goods?
No. Confirmation and irrevocability are both about who is obligated to pay, not about whether the goods meet the buyer's expectations. Payment under a letter of credit depends on presenting documents that match its terms exactly, not on the buyer's satisfaction with the shipment itself.
How much does letter of credit confirmation typically cost?
It varies with the issuing bank's perceived risk and the confirming bank's own pricing, and typically runs 0.5% to 2% of the credit's value for a single shipment, sometimes more on higher-risk corridors. Ask your bank for an indicative quote before you commit to confirmed terms in a contract, since that number can change the economics of the deal.
Does it matter which country the confirming bank is in?
It matters in practice, even though UCP 600 doesn't require it. Exporters usually choose a confirming bank in their own country, or one with an established correspondent relationship with the issuing bank, since that makes the eventual payment faster to receive and easier to chase if anything goes wrong.
