Introduction
A documentary credit works on documents. Banks do not decide whether the goods are actually satisfactory; they decide whether the documents presented under the credit constitute a complying presentation.
This makes discrepancy handling one of the most important operational areas in documentary credits. A documentary inconsistency can affect honour or negotiation, but a bank cannot reject documents casually. UCP 600 lays down a disciplined process for examination, refusal, waiver and notification.
For CAIIB BFM, this topic is especially important in case studies because the examiner may give a set of documents, identify one or more irregularities and test whether the bank's action was correct. The key is not only to identify a discrepancy but also to know what the bank must do after finding it.
Under UCP 600, a nominated bank acting on its nomination, a confirming bank, if any, and the issuing bank examine the presentation on the basis of the documents alone to determine whether it appears to constitute a complying presentation. Each has a maximum of five banking days following the day of presentation to make that determination.
Learning Objectives
After studying this topic, you should be able to:
Explain what makes a presentation complying or discrepant.
Understand the document-examination standard under UCP 600.
Apply the five-banking-day rule correctly.
Explain the issuing bank's option to seek an applicant waiver.
Identify the mandatory contents of a valid refusal notice.
Analyse when a bank may lose the right to rely on discrepancies.
Core Concept: What Is a Discrepant Presentation?
A presentation becomes discrepant when the documents do not comply with the terms and conditions of the documentary credit, the applicable provisions of UCP 600, or international standard banking practice.
This does not mean that every difference in wording is automatically a discrepancy.
UCP 600 Article 14 states that data in a document, when read in the context of the credit, the document itself and international standard banking practice, need not be identical, but must not conflict with data in that document, another stipulated document or the credit.
Therefore, document examination is based on consistency and compliance, not mechanical word-for-word matching.
The current International Standard Banking Practice for examination of documents is ISBP 821, 2023 edition. ICC describes it as the most up-to-date guide for examination of documents under UCP 600 and states that it should be read together with UCP 600.
Common Sources of Discrepancies
Discrepancies may arise in almost any stipulated document. Common areas include:
Late presentation
Presentation after credit expiry
Shipment after the latest shipment date
Missing stipulated document
Incorrect or conflicting goods description
Invoice amount exceeding the permitted credit amount
Transport document not meeting credit requirements
Incorrect consignee or notify-party details where relevant
Insurance document not meeting required coverage or date conditions
Missing signature where a signature is required
Inconsistent dates
Certificate not issued by the required party
Documents containing data that conflict with the credit or other documents
The correct approach is always to test the actual document against the credit and applicable rules. Memorising a list of "standard discrepancies" without reading the credit is unsafe.
Document Examination Before Refusal
A refusal under Article 16 normally follows proper examination under Article 14.
The examining bank should proceed logically:
Read the credit and accepted amendments.
Identify every stipulated document.
Check whether the presentation was made within the applicable time limits.
Examine each document on its face.
Compare relevant data across the documents and the credit.
Apply UCP 600 and applicable ISBP principles.
Record all discrepancies identified.
Decide whether the presentation is complying or non-complying.
Banks deal with documents, not with the underlying goods, services or performance. This documentary principle is fundamental to the examination and refusal process.
This is one of the most important CAIIB points.
Under UCP 600 Article 14(b), the nominated bank acting on its nomination, the confirming bank, if any, and the issuing bank each have a maximum of five banking days following the day of presentation to determine whether the presentation is complying.
The day of presentation itself is not counted as the first of the five banking days.
The examination period is also not shortened merely because the credit expires or the last day for presentation occurs after the presentation has already been made.
Example of Counting
Assume documents are presented on Monday and all following weekdays are banking days.
The five banking days following presentation are:
Tuesday – Day 1
Wednesday – Day 2
Thursday – Day 3
Friday – Day 4
Monday – Day 5
If the bank decides to refuse, the Article 16 notice must be sent no later than the close of that fifth banking day.
What Happens When Documents Are Discrepant?
Article 16 applies when a nominated bank acting on its nomination, a confirming bank, if any, or the issuing bank determines that the presentation does not comply.
Such a bank may refuse to honour or negotiate. If it decides to refuse, it must follow the Article 16 notice procedure.
The bank cannot simply remain silent, send an incomplete refusal or continue raising discrepancies one by one over an extended period.
The refusal mechanism is designed to give the presenter clear and timely information.
Applicant Waiver of Discrepancies
When the issuing bank finds a non-complying presentation, it may, in its sole judgement, approach the applicant for a waiver of the discrepancies.
This is an option available to the issuing bank. It is not an automatic right of the applicant or beneficiary.
Most importantly, seeking a waiver does not extend the five-banking-day examination period under Article 14(b).
The bank therefore cannot delay the required Article 16 action merely because the applicant has not yet responded.
Is the Applicant's Waiver Automatically Binding on the Issuing Bank?
No.
The issuing bank decides whether to approach the applicant. Even if the applicant agrees to waive the discrepancies, the issuing bank must itself agree to accept that waiver.
Article 16 permits the issuing bank to hold the documents until it receives an applicant waiver and agrees to accept it, or receives further instructions from the presenter before agreeing to the waiver.
Requirements of a Valid Refusal Notice
This is the heart of Article 16.
When the bank decides to refuse to honour or negotiate, it must give a single notice to the presenter.
That notice must cover three essential matters.
1. Clear Statement of Refusal
The notice must clearly state that the bank is refusing to honour or negotiate.
It should not leave the presenter uncertain about whether the bank has actually refused the presentation.
2. Every Discrepancy Relied Upon
The notice must state each discrepancy on which the refusal is based.
This is extremely important.
The bank should therefore complete its examination before sending the refusal notice and include all discrepancies on which it intends to rely.
3. Status or Disposal of the Documents
The notice must also state what is being done with the documents.
Article 16 provides alternatives, including that:
the bank is holding the documents pending further instructions from the presenter;
the issuing bank is holding them while seeking an applicant waiver and until it agrees to accept that waiver, or receives further instructions before agreeing to it;
the bank is returning the documents; or
the bank is acting according to instructions previously received from the presenter.
Therefore, merely identifying discrepancies is not enough. The refusal notice must also properly address the position of the documents.
How and When Must the Notice Be Sent?
The refusal notice must be given by telecommunication or, if that is not possible, by another expeditious means.
It must be given no later than the close of the fifth banking day following the day of presentation.
In banking operations, authenticated channels such as SWIFT may be used where appropriate.
For CAIIB, remember the broader rule:
Correct refusal requires both proper content and timely communication.
A genuine discrepancy communicated through a defective or late refusal notice can still create an Article 16 problem.
Consequence of Defective Refusal: Preclusion
Article 16(f) contains a very important consequence.
If an issuing bank or confirming bank fails to act in accordance with Article 16, it is precluded from claiming that the documents do not constitute a complying presentation.
In simple language, a bank that mishandles its refusal may lose the right to rely on the discrepancies.
This makes procedural discipline as important as correct document examination.
Situations That Can Create Preclusion Risk
Examples include:
refusal notice sent too late;
failure to state clearly that the bank is refusing;
failure to state every discrepancy relied upon;
defective handling of the document-status or disposal requirement; or
other failure to comply with Article 16.
An ICC Banking Commission opinion published in 2024 also illustrates the practical importance of the time requirement. The case involved a refusal notice sent later than the permitted period; the late refusal was challenged and the presentation was subsequently honoured.
Integrated Case Study: Discrepant Export Documents
Consider an issuing bank that has issued a documentary credit subject to UCP 600 in favour of an exporter.
The beneficiary presents:
Commercial invoice
Bill of lading
Insurance document
Certificate of origin
During examination, the issuing bank finds two problems:
The bill of lading shows shipment after the latest shipment date stated in the credit.
The certificate of origin was issued by the beneficiary although the credit specifically requires it to be issued by a chamber of commerce.
The bank receives the documents on Monday.
Stage 1: Are the Differences Discrepancies?
Yes.
Shipment after the expressly stated latest shipment date does not comply with the credit.
The certificate of origin has also not been issued by the party specifically required by the credit.
These are not merely harmless wording differences.
Stage 2: Can the Bank Contact the Applicant?
Yes.
The issuing bank may, in its sole judgement, ask the applicant whether it wishes to waive the discrepancies.
However, approaching the applicant does not extend the Article 14(b) period.
The bank must continue to track the five-banking-day deadline.
Stage 3: Applicant Agrees to Waive
Assume the applicant informs the issuing bank that it is willing to accept both discrepancies.
This does not automatically bind the issuing bank.
The issuing bank must decide whether it agrees to accept the applicant's waiver.
If the bank agrees to accept the waiver and proceeds accordingly, refusal may no longer be necessary.
Stage 4: Applicant Does Not Respond in Time
Assume instead that the applicant remains silent.
The bank cannot use that silence as a reason to allow the five-banking-day period to expire.
If the bank intends to refuse, it must issue the required Article 16 notice within the prescribed time.
Stage 5: Preparing the Refusal Notice
A compliant notice should clearly state:
that the bank refuses to honour;
discrepancy 1: shipment effected after the latest shipment date;
discrepancy 2: certificate of origin not issued by the required chamber of commerce; and
the applicable status or disposal of the documents.
The notice must also be communicated within the permitted period.
Stage 6: Bank Mentions Only One Discrepancy
Suppose the bank refuses on the basis of late shipment but omits the certificate-of-origin discrepancy from its single refusal notice.
Article 16 requires the refusal notice to state each discrepancy in respect of which the bank refuses. The bank should therefore not expect to preserve an omitted discrepancy for a later refusal.
This demonstrates why complete document scrutiny should be finished before the refusal notice is transmitted.
Practical Banking Application
For branch and trade-finance staff, discrepancy handling requires control at three levels.
Examination Control
Use the credit, accepted amendments, UCP 600 and applicable ISBP as the examination framework.
Do not reject documents merely because wording is different when the relevant data does not conflict.
Time Control
Record the exact date of presentation and determine the fifth banking day immediately.
Any applicant-waiver process must operate within the same timeline.
Communication Control
Before transmitting refusal, verify that the notice:
is given to the presenter;
clearly states refusal;
lists every discrepancy relied upon;
states the permitted document-status or disposal position; and
is sent within the Article 16 deadline.
This disciplined approach reduces operational and legal risk.
CAIIB Exam Focus
Five Banking Days, Not Five Calendar Days
The examination period is a maximum of five banking days following the day of presentation.
Waiver Does Not Extend the Deadline
Approaching the applicant for waiver does not provide additional examination or refusal time.
Applicant Waiver Is Not Automatically Binding
The issuing bank must itself agree to accept the waiver.
Single Notice Is Required
The refusal should not be fragmented into a series of messages that progressively add discrepancies.
Every Relied-Upon Discrepancy Must Be Stated
The bank should identify all discrepancies before communicating refusal.
Document Status Must Be Covered
The refusal notice must state the applicable position regarding the documents.
Defective Refusal Can Cause Preclusion
For the issuing bank or confirming bank, failure to comply with Article 16 can result in loss of the right to claim that the presentation is non-complying.
Common Exam Traps
Trap 1: “The Bank Has Five Days from the Date of Presentation”
Incorrect.
The rule is a maximum of five banking days following the day of presentation.
Trap 2: “The Applicant Can Order the Issuing Bank to Accept Discrepancies”
Incorrect.
The issuing bank may seek a waiver in its sole judgement and must itself agree to accept the waiver.
Trap 3: “Waiting for Applicant Waiver Extends the Refusal Period”
Incorrect.
Article 16 expressly provides that seeking applicant waiver does not extend the Article 14(b) period.
Trap 4: “A Refusal Notice Only Needs to List the Discrepancies”
Incorrect.
It must also state that the bank is refusing and specify the applicable position regarding the documents.
Trap 5: “A Bank Can Add Another Discrepancy Later”
Unsafe.
Article 16 requires a single notice stating each discrepancy on which the bank refuses.
Trap 6: “Any Difference Between Documents Is a Discrepancy”
Incorrect.
Data need not be identical. The important test is whether the data conflict with the credit, the document itself, another stipulated document or applicable international standard banking practice.
Memory Technique
For a refusal notice, remember R-D-D-T:
R – Refusal clearly stated
D – Discrepancies: every relied-upon discrepancy stated
D – Documents: status or disposal stated
T – Time: notice sent within the prescribed five-banking-day limit
This provides a simple CAIIB case-study checklist for analysing whether refusal has been handled correctly.
