How to Avoid LC Discrepancies: The 15 Most Common Rejections

Why documents get rejected under a letter of credit, the ISBP 821 rules behind the top 15 discrepancies, and the pre-presentation checks that stop most of them at source.

By SSLT Global Editorial·Published

Every rejected LC presentation costs money, delays payment and chips away at the relationship with the applicant. The good news is that discrepancies cluster - the same 15 errors account for the overwhelming majority of rejections year after year. This guide walks through the top 15 in the order they appear in an ISBP 821 examination, with the fix for each.

The 15 most common LC discrepancies

  1. Late presentation - documents presented after the 21-day post-shipment window (or the shorter window specified in the LC). Fix: build a presentation calendar from the on-board date the moment the B/L is issued.
  2. Missing on-board notation - transport document does not evidence loading on board. Fix: request a dated on-board endorsement from the carrier before pickup.
  3. Description of goods inconsistent - invoice uses different wording from the LC's Field 45A. Fix: copy-paste the exact Field 45A description into the invoice.
  4. LC amount exceeded - invoice or drawing is larger than the LC value, without a 5 or 10 percent tolerance clause. Fix: split the shipment or amend the LC before presenting.
  5. Expired LC - presentation date is after the expiry in Field 31D. No fix without applicant waiver.
  6. Insurance amount insufficient - policy value is below 110 percent of CIF as required by UCP 600 Article 28. Fix: instruct the insurer to endorse the correct value at issuance.
  7. Insurance dated after shipment - policy effective date is later than the on-board date. Fix: request back-dated cover to the shipment date.
  8. Missing or wrong signatures - documents that must be signed (invoice, packing list, certificate of origin) are unsigned or signed by the wrong party. Fix: checklist every document against ISBP 821's signature rules.
  9. Bill of lading not marked "clean" - carrier has annotated damage or shortage. Fix: negotiate a clean B/L with the carrier or refuse the shipment.
  10. Math errors on the invoice - unit price times quantity does not equal the total. Fix: automate totals from the source system.
  11. Weight or measurement mismatch - B/L, packing list and invoice show different weights. Fix: base all three documents on the same measurement source.
  12. Certificate of origin not legalised - the LC requires legalisation by an embassy or chamber and the document is only chamber-attested. Fix: read Field 46A carefully at LC receipt; legalisation can take a week.
  13. Missing beneficiary declarations - LC asks for a signed statement (e.g. "goods are of X origin") that is not presented. Fix: extract every required declaration from Field 46A into your document checklist.
  14. Draft drawn on wrong party - bill of exchange drawn on the applicant when the LC requires drawing on the issuing bank. Fix: use the drawee named in Field 42a.
  15. Late or missing telex advice - LC requires shipment advice by SWIFT within X days of shipment and proof is not presented. Fix: send the advice on the day of shipment and file the acknowledgement with your presentation.

The pre-presentation drill

Before couriering documents, run one final examination:

  1. Compare goods description across every document.
  2. Verify dates: shipment, on-board, insurance, invoice.
  3. Check totals arithmetically on every priced document.
  4. Confirm every required signature is present and correct.
  5. Match required document count against Field 46A.

The LC Documents Checklist automates all five steps against the specific Field 46A wording of your LC and the general ISBP 821 rules. Its Draft Review tab also scans the MT700 for issuance-side traps that seed downstream discrepancies.

Frequently asked questions

What are the most common LC discrepancies?#

ICC surveys consistently place the same offenders at the top: late presentation (documents presented after the 21-day post-shipment window), missing on-board notation on the bill of lading, inconsistent description of goods between invoice and other documents, LC amount exceeded, missing or wrong signatures, expired insurance certificate, and math errors on the invoice. Together these account for around 60 percent of all rejections.

Why are documents rejected under an LC?#

UCP 600 Article 14 requires documents to comply with the terms of the LC, be consistent with each other and follow international standard banking practice (ISBP 821). If any one of those three tests fails, the issuing bank has grounds to reject. The discrepancy has to be flagged within five banking days (Article 16), and the reasons must be specific - a generic 'documents non-compliant' notice is itself a breach.

Can a discrepancy be corrected after rejection?#

Sometimes. If the LC has not expired and the presentation is still within the 21-day post-shipment window, the beneficiary can amend or re-issue the document and re-present. If the LC has expired or the window has passed, the only route is applicant waiver - the applicant instructs the issuing bank to accept the discrepant documents. Most applicants will waive if the goods are what they ordered; they will not waive if they have already found a cheaper supplier or the market has moved against them.

What is the 21-day presentation rule?#

UCP 600 Article 14(c) says original transport documents must be presented no later than 21 calendar days after the shipment date, and in any event not after the LC expiry. Many LCs shorten the window; almost none extend it. Missing the 21 days is one of the top three discrepancies and usually fatal - the applicant has no reason to waive because the shipment is already late in the buyer's supply chain.

How does the LC Documents Checklist tool help?#

It runs each document through the ISBP 821 rules relevant to that document type and the specific LC terms you paste in, flagging discrepancies before you present. The Draft Review tab also parses MT700 field values and highlights common trap fields (47A, 45A, 46A wording) that generate downstream discrepancies.
