Common letter of credit discrepancies and why a bank can refuse payment over them

Level: PractitionerTime: 45 minutesOrder used: B (the jeans)Tool: Letter of credit document checklist
This lesson is for anyone who prepares or checks documents presented under a letter of credit and needs to know why a bank can refuse payment even after goods have shipped. Lessons 15.2.1 and 15.2.2 are assumed. Figures are teaching examples; at work, check your own documents against your own letter of credit's own wording.

This page names the discrepancies that most often cause a bank to refuse payment on documents presented under a letter of credit

A discrepancy is a difference between a presented document and a letter of credit's own terms, or between two presented documents, and the standard rules for letters of credit let a bank refuse payment over even one, however small. Anyone preparing or checking documents needs to know the discrepancies that recur most often, since a bank does not correct them on the beneficiary's behalf.

This matters to Delta Garments and Northline Apparel on Order B (the jeans), since a discrepancy found after shipment does not stop the goods moving, but it does stop the payment the credit was meant to guarantee. Sara and Mona both want the documents checked before presentation, not after a refusal.

Without this skill, a factory can ship goods correctly and still not be paid on time, because the papers describing the shipment do not match the letter of credit's own wording exactly. This lesson names the discrepancies that recur most often, states the rule for why even a small one is enough, and works through Order B (the jeans)'s own documents as Northline's own bank reviews them.

03Before you start

You need: lessons 15.2.1 and 15.2.2, since this lesson assumes you already know what a letter of credit promises and which of its own terms a factory must have already read and accepted.

By the end of this lesson you can:

  • state the rule that even one discrepancy is enough for a bank to refuse payment;
  • name the discrepancies that recur most often across letter of credit presentations;
  • check a set of shipment documents against each other, not only against the letter of credit itself;
  • explain why a late shipment is a discrepancy even if the goods themselves are correct;
  • recognise a discrepancy in Order B (the jeans)'s own documents before presentation, not after refusal.

Not covered here: fixing a letter of credit's own terms in advance, through a formal amendment, is lesson 15.2.4's own subject; assembling the full document checklist is lesson 15.2.5's own subject.

05Teaching
The rule

A bank can refuse payment over a single discrepancy, however small, because a letter of credit pays against documents, not against the goods themselves

The internationally standard rules for letters of credit require a bank to examine presented documents on their face, checking whether they comply with the letter of credit's own terms and with each other, without inspecting the actual goods that have shipped. This means a bank's decision to pay is based entirely on paper, and a single discrepancy, a date, a quantity, a missing signature, a spelling difference between two documents naming the same party, is enough grounds for refusal, whatever the physical condition or correctness of the goods themselves. The goods can be perfect and still unpaid on time, because the papers describing them did not match.

Goods shipped(not examined by the bank)Documents presentedinvoice, packing list, B/L...Bank's decisionpay, or refuse over a discrepancy
The bank's decision runs from the documents, not from the goods themselves. A discrepancy in the papers is enough grounds for refusal, even when the shipped goods exactly match what the buyer ordered.
What you meet in real life

The same paper-based rule applies to any letter of credit, but which discrepancy recurs most often differs by what goes wrong on a given order

What can differThe shapes you will meetWhy it matters
A late shipment against the letter of credit's own latest shipment date, as on a domestic, made-to-order order like Order B (the jeans)The bill of lading's own loading date falls after the date the letter of credit fixed, even by a single day.The rule allows refusal for this alone; a shipment that is otherwise perfect is still late on paper if the date printed on the bill of lading says so.
Documents that do not match each other, most often the invoice, packing list and bill of lading disagreeing on quantity or descriptionOne document states 3,000 pieces, another states 2,998, or one names "jeans" and another names "trousers" for the same goods.Banks compare documents against each other as well as against the letter of credit; an internal mismatch is a discrepancy even if every individual document is otherwise correctly filled in.
A missing or incorrect signature, endorsement or certification the letter of credit itself requiredA final inspection report is unsigned, or a document is not endorsed the way the letter of credit specifies.A document is examined for whether it meets every stated requirement exactly, not for whether it is close enough or clearly genuine in substance.
An expired letter of credit at the time documents are actually presented, even if shipment itself was on timeGoods shipped inside the shipment date, but the documents reach the bank after the letter of credit's own expiry date.Confirms that both dates named in lesson 15.2.2, the shipment date and the expiry date, must be met; meeting one does not excuse missing the other.
The case we follow

Northline Apparel's own bank finds Order B's own packing list states a different piece count than the commercial invoice

Once Delta Garments ships Order B (the jeans), Mona assembles the documents for presentation: the commercial invoice, the packing list, the bill of lading, and the final inspection report, exactly as the letter of credit's own required-documents list, read in lesson 15.2.2, states. Northline's own issuing bank examines the set on its face before paying, checking each document against the letter of credit and against the other documents in the set.

The worked number

The order value a single quantity mismatch between two documents places at risk on Order B

Order B's own total order value under its letter of credit is USD 29,400 (9.80 × 3,000 pieces, from lesson 15.2.1's own worked number).

Order B's own commercial invoice states: 3,000 pieces
Order B (the jeans)'s own packing list states: 2,998 pieces (two pieces held back for a repair)
Because these two documents do not match each other:
the whole presentation is a discrepancy, not only the 2 pieces in question
Order value the bank can lawfully refuse to pay against this one discrepancy:
USD 9.80 × 3,000 = USD 29,400 refusable, not merely USD 19.60 (9.80 × 2)
What seems at riskUSD 19.60 (2 pieces)What is actually at riskUSD 29,400 (whole presentation)
A discrepancy affecting 2 pieces out of 3,000 still exposes the full USD 29,400 order value to refusal. The bank refuses the whole presentation as non-complying, not only the value of the mismatched quantity.
The method

How to check a set of documents for discrepancies before presenting them to a bank

  1. Compare every document against the letter of credit's own wording, term by term, not from memory of what the letter of credit generally requires.
  2. Compare every document against every other document in the set, checking that quantities, descriptions and dates agree across all of them.
  3. Confirm the bill of lading's own loading date falls on or before the latest shipment date, since a late loading date is a discrepancy even if presentation itself happens in time.
  4. Confirm every signature, endorsement or certification the letter of credit requires is actually present, not assumed to be attached separately.
  5. Present the complete set within the presentation period, counted from the shipment date, well before the letter of credit's own expiry date.
  6. Correct any discrepancy found before presentation, since a bank examining documents after the fact will not correct them on the beneficiary's behalf.
The trap

Assuming a small, clearly unintentional mismatch will be overlooked because the goods themselves are correct

A common mistake is treating a minor difference, two pieces held back for a repair, a shortened company name on one document, a date one day later than another, as too small to matter, on the assumption a bank will read the intent behind the paperwork rather than the paperwork itself. The internationally standard rules for letters of credit do not ask a bank to judge intent; they ask it to check compliance, and a bank that finds any discrepancy is entitled to refuse the whole presentation, leaving the beneficiary to renegotiate payment on weaker terms for a shipment that has already left the factory.

06In plain words

A bank pays against paper, not against the actual goods on the ship, so it checks whether the papers match the letter of credit's own words and match each other, and it is allowed to say no over even one small difference. The most common differences are a shipment that is a day late by the date on the bill of lading, two documents that state different numbers or names for the same shipment, a missing signature the letter of credit asked for, and documents that reach the bank after the letter of credit's own final date. None of these mean the goods themselves are wrong; they mean the paperwork describing the goods does not exactly match what the bank was told to expect, and that alone is enough for the bank to refuse to pay until it is fixed.

07Quick check
  • A bank examines documents, not the physical goods, and can refuse payment over a single discrepancy.
  • A shipment loaded even one day after the latest shipment date is a discrepancy, whatever the goods' own condition.
  • Documents that disagree with each other, not only with the letter of credit, are also discrepancies.
  • A missing signature or certification the letter of credit requires is a discrepancy, even if the document is otherwise correct.
  • A discrepancy exposes the whole presentation's order value to refusal, not only the value of the mismatched detail.
  • Documents reaching the bank after the letter of credit's own expiry date are a discrepancy, even if shipment itself was on time.
08Workplace scenario

Sara's own team at Northline Apparel is told its bank has flagged a discrepancy on Order B's own presented documents

Sara, the buyer at Northline Apparel, is informed by Northline's own issuing bank that a discrepancy has been found in the documents Delta Garments presented for Order B (the jeans).

  • The bank's own notice states the commercial invoice and packing list state different piece counts, 3,000 against 2,998.
  • Northline Apparel still wants the shipment and does not dispute that the goods themselves are correct.
  • The bank has not yet paid Delta Garments, and will not do so on this presentation as it stands.
  • Sara can instruct her own bank to waive the discrepancy and pay anyway, since the applicant is entitled to accept a discrepancy the bank itself has found.

The document Sara reads:

Northline's own issuing bank's discrepancy notice: "Commercial invoice states 3,000 pieces; packing list states 2,998 pieces. Documents do not comply. Applicant's instruction required."

Should Sara instruct her own bank to refuse payment outright over the mismatch, or waive the discrepancy since she does not dispute the shipment itself? Decide before opening the answer.

Show decision

Sara should instruct her own bank to waive the discrepancy and proceed with payment, since she does not dispute the shipment.

First fact. The rule in this lesson is that a bank may refuse a non-complying presentation; it does not require the applicant to insist on that refusal once notified, and Sara, as the applicant, is entitled to accept the documents as presented despite the discrepancy.

Second fact. Refusing payment outright over a 2-piece difference Northline does not actually dispute would delay a shipment already in transit and correct in substance, without protecting Northline from any real loss, since the two documents' own mismatch does not change what physically shipped.

Waiving the discrepancy lets Order B (the jeans)'s own USD 29,400 payment proceed without further delay; insisting on refusal instead would cost both sides time over a difference Sara has already confirmed does not concern her.

09What it costs

The order value delayed while a discrepancy is resolved on Order B

Order B (the jeans)'s own total order value under its letter of credit is USD 29,400 (9.80 × 3,000 pieces, from lesson 15.2.1's own worked number). While a discrepancy notice is outstanding, none of that USD 29,400 is paid under the letter of credit, whatever the goods' own condition; resolving it, whether by correcting the documents before a second presentation or by the applicant waiving it as Sara does here, is what releases payment, and every day the discrepancy stays open is a day the factory's own working capital for Order B (the jeans) remains tied up in a shipment it has already sent.

Letter of credit document checklist: the discrepancy-check row this lesson adds

Continue the Letter of credit document checklist by adding, for each required document, a column confirming it has been checked against the letter of credit itself and against every other document in the set, before presentation. Record any discrepancy found, and whether it was corrected or waived by the applicant, so the checklist shows the presentation's own final status.
