LC Amendment Request: How to Ask Without Losing the Deal.

A simple guide for exporters on when and how to ask your buyer for an LC amendment.

You carefully reviewed your letter of credit. You found a problem.

It might be a mismatch in goods description between the one mentioned in Field 45A and what you are actually shipping. It might be the latest shipment date mentioned in Field 44C that’s not enough time for you. It might be a clause in Field 47A that makes payment conditional upon your buyer’s approval.

You know there is a problem. You don’t know what to do next.

Here’s what most exporters miss at this moment. The clock is ticking. Getting your LC amendment confirmed through the banking system requires 5 to 10 business days, and if your shipment is in two weeks, you have no margin.

What follows is the exact process:

• How to write the request
• How to approach the buyer to get cooperation instead of resistance
• What happens inside the banking system after you send it
• How to verify the amendment is correct when it arrives

What an LC Amendment Actually Is

An LC amendment is a formal modification to the original letter of credit in order to make it workable before you ship.

An amendment is not as simple as a phone call or email agreement between buyer and seller. It is the change that must travel through the same banking chain as the original LC.

Here is how that chain works:

Step 1 → The applicant — your buyer — instructs the issuing bank to issue an amendment.

Step 2 → The issuing bank then sends an official SWIFT MT707 amendment message to your advising bank. (3–5 business days)

Step 3 → Your advising bank notifies you. (1–2 business days)

This process takes time. Depending on the banks involved, allow 5 to 10 business days from the moment your buyer instructs their bank to the moment you are notified. If your shipping date is in 10 days, you have no margin.

The Request Your Buyer Can Act On

You identified the problem. You verbally explain that to your buyer. Your buyer nods, yet days pass but nothing moves.

The reason is your buyer needs to instruct its bank in writing and the bank requires precise language to issue an amendment correctly. If you explain it vaguely, the buyer will give vague instructions to the bank and as a result either amendment arrives wrong or doesn’t arrive at all.

Under UCP 600 Article 10, an LC amendment is accepted in its entirety. You cannot pick and choose which changes to accept. This makes your outgoing request equally important. If you send an incomplete request and the buyer instructs an amendment based on that, then you need another cycle for what was missed — more time, more fees and tighter shipping window.

Write your request for amendment in a way that your buyer can directly forward to the bank.

Your request must include:

• Your LC number and issue date
• The specific field to be changed (e.g., Field 44C: Latest Date of Shipment)
• The current wording, as exactly quoted in the LC
• Exact replacement you need
• A brief and factual one line reason

Don’t frame your request like “There are some issues with the LC dates and we can’t proceed without adjusting them.” This tells them nothing specific. Nothing they can act on.

Instead, frame it like

LC No. [XXXX], [Issue Date]

Amendment required:

Field 44C: Latest Date of Shipment Current: 10 July, 2026; Requested: 31 July, 2026

Reason: Production timeline requires 28 days from LC receipt, current date doesn’t allow compliant shipment.

Please instruct your bank to issue this amendment at your earliest convenience.

If you have to request multiple amendments, mention all of them in a single request.

Each amendment cycle costs time and bank fees for both parties.

How to Have Conversation With Your Buyer

At this point, many exporters hesitate. They think flagging a problem in the LC will signal incompetence.

Exporters who catch the problem before shipment and raise it professionally are the ones who are fully aware of the LC process. And buyers who have been actively involved in trade finance know that it’s a routine matter and LC amendments are common.

When you contact your buyer:

• Be specific and unapologetic. You are not reporting failure. You are protecting both sides of the transaction.
• Frame the request around their interest too. A discrepancy caught after shipment will also hold up their documents. Goods will be stuck in transit. This all can be prevented with an amendment now.
• Clearly communicate the timeline for amendment. Communicate the deadline plainly not urgently like “We need to receive amended LC by [date] to meet the agreed shipment window.”

For instance, you can frame your request like:

“After reviewing LC, I have found [number] terms that if left unchanged will result in discrepant documents at presentation. To protect transactions for both parties, I have prepared a proposed amendment with required corrections — please find attached. We need to receive amended LC by [date] to proceed with shipment on schedule.”

A buyer acting in good faith will respond to such a well-documented request. If they become evasive or difficult, then there is something worth paying attention to.

When Your Amendment Arrives — Read It Before You Accept

When the amended LC arrives, don’t assume it says what you asked for.

Errors happen during amendment because it has passed through multiple hands before reaching you. The buyer instructs their bank, bank staff translates the instruction to SWIFT MT707 format, and your advising bank reformats it before it reaches you. At every handoff, a word can be paraphrased, a date can shift by one digit, or a field can be partially revised.

Read the amended LC carefully and confirm it against your original request. Before proceeding, make sure:

• All the changes you asked for have been made.
• Each change reflects the exact wording you requested, not the bank’s interpretation of it.
• No new terms have been added.
• The expiration date is still workable.
• You still have enough time for shipment.

If you still find something wrong, go back to your buyer again with another specific amendment request.

Accept Formally — Then Brief Your Entire Team

Under UCP 600 Article 10, an amendment is binding only when the beneficiary formally accepts it. If you present documents compliant with amended terms, silence can be treated as acceptance, but don’t rely on that.

The safest approach is to notify your advising bank in writing confirming acceptance of the amended terms. Keep a copy.

From this point forward, every document must align with the amended terms: commercial invoice, Bill of Lading, packing list, certificate of origin, and any other document listed under Field 46A.

Once you accept the amendment, the original LC is no longer valid. Brief your freight forwarder, your document preparer. Everyone handling documents must now work on amended terms.

Key Takeaways

The amendment process works when you run it completely and early. A fully written request before any confirmation, a verified amendment before acceptance, and amended LC briefed to your entire document team.

If you have already shipped, the amendment window is closed.
