Introduction
Document scrutiny is at the heart of a documentary credit transaction.
When documents are presented under a Letter of Credit (LC), banks do not inspect the actual goods. They examine the documents to determine whether the presentation complies with:
the terms and conditions of the credit;
UCP 600; and
international standard banking practice.
UCP 600 Article 14 requires the concerned banks to determine compliance on the basis of the documents alone. Data in different documents need not be identical, but they must not conflict when read in the context of the credit, the document itself and international standard banking practice.
For practical document examination, ISBP 821, 2023 edition, is the current ICC guide and is intended to be read together with UCP 600.
For CAIIB BFM, the examiner may provide an LC together with an invoice, bill of lading, insurance certificate, certificate of origin or packing list and ask whether the documents are compliant. The correct approach is therefore document-by-document scrutiny followed by a cross-document consistency check.

Scrutinise certificates, packing lists and other ancillary documents.
Identify common documentary discrepancies in integrated CAIIB case studies.
Foundation Rule: Banks Examine Documents, Not Goods
A documentary credit is separate from the underlying sale or other contract.
The bank's task is therefore not to decide:
whether the goods are of good quality;
whether the buyer is commercially satisfied;
whether the exporter actually performed every contractual obligation; or
whether statements appearing in documents are factually true through physical investigation.
Its task is to determine whether the documents presented constitute a complying presentation.
General Standards for Scrutiny
Before examining individual documents, some Article 14 principles should be applied to the entire presentation.
Data Need Not Be Identical
The wording in two documents does not have to be exactly the same.
The requirement is that the data must not conflict.
For example, a minor difference in wording may be acceptable if both documents clearly describe the same transaction without contradiction.
Goods Description Outside the Invoice
In documents other than the commercial invoice, the description of goods, services or performance may be stated in general terms, provided it does not conflict with the description in the credit.
This is different from the commercial invoice, where the goods description must correspond with the description appearing in the credit.
Unspecified Ancillary Documents
If the credit requires a document other than a transport document, insurance document or commercial invoice but does not state:
who must issue it; or
what data it must contain,
the bank may accept a document whose content appears to fulfil the required function and otherwise satisfies the non-conflict rule.
Documents Not Required by the Credit
A document presented but not required by the credit is disregarded and may be returned.
Banks should not create discrepancies from irrelevant documents that the credit did not require.
Presentation Period for Transport Documents
A presentation containing one or more original transport documents governed by UCP 600 Articles 19–25 must generally be made not later than 21 calendar days after the date of shipment, and in any event not later than the credit expiry date.
Scrutiny of the Commercial Invoice
The commercial invoice is governed principally by UCP 600 Article 18.
It is usually one of the most important documents because it contains the detailed description and value of the goods.
1. Issuer
The commercial invoice must appear to have been issued by the beneficiary, subject to the special provisions applicable to transferable credits.
2. Name of Applicant
The invoice must normally be made out in the name of the applicant.
Therefore, if the LC applicant is ABC Ltd. but the commercial invoice is issued to an unrelated entity without an applicable exception, scrutiny is required for a possible discrepancy.
3. Currency
The commercial invoice must be made out in the same currency as the credit.
4. Signature
A commercial invoice need not be signed under UCP 600 unless the credit itself requires a signed invoice.
This is a common examination trap.
5. Description of Goods
The description of goods, services or performance in the commercial invoice must correspond with that appearing in the credit.
This does not require blind word-for-word reproduction, but the invoice description cannot alter or contradict the credit's description.
6. Invoice Amount
A bank may accept an invoice issued for an amount greater than the amount permitted by the credit, but it must not honour or negotiate for an amount exceeding that permitted by the credit.
Therefore, an invoice amount above the credit amount is not automatically analysed in the same way as a drawing exceeding the available credit amount.
Scrutiny of Transport Documents
The applicable rule depends on the type of transport document.
Important UCP 600 provisions include:
Transport Document | UCP 600 Article |
|---|---|
Multimodal or combined transport document | 19 |
Bill of lading | 20 |
Non-negotiable sea waybill | 21 |
Charter party bill of lading | 22 |
Air transport document | 23 |
Road, rail or inland waterway document | 24 |
Courier/post receipt | 25 |
Clean transport document | 27 |
The banker should first identify which article applies before checking the document.
Bill of Lading Scrutiny
For a bill of lading under Article 20, important checks include the following.
Carrier and Signature
The document must indicate the name of the carrier and be signed by:
the carrier;
a named agent for or on behalf of the carrier;
the master; or
a named agent for or on behalf of the master.
Where an agent signs, the capacity in which the agent signs must be appropriately indicated.
Shipped on Board
The bill of lading must indicate that the goods have been shipped on board a named vessel at the required port of loading.
This may be evidenced by:
pre-printed wording; or
an on-board notation.
Where the bill of lading contains an on-board notation with a date, that date is generally treated as the shipment date.
Ports
The document should indicate shipment from the port of loading to the port of discharge stated in the credit.
Special attention is required where terms such as “intended vessel” or an intended port appear, because additional on-board information may then be necessary.
Originals
If more than one original bill of lading has been issued, the full set indicated on the bill of lading must be presented.
Charter Party Indication
An Article 20 bill of lading must contain no indication that it is subject to a charter party.
If the LC permits or requires a charter party bill of lading, Article 22 applies instead.
Clean Transport Document
Under Article 27, banks accept a clean transport document.
A document is not clean if it carries a clause or notation expressly declaring a defective condition of:
the goods; or
their packaging.
Importantly, the word “clean” itself need not appear, even where the credit asks for a “clean on board” transport document.
Air Transport Document Scrutiny
An air transport document under Article 23 must, among other things:
identify the carrier;
be signed by the carrier or a named agent acting for the carrier;
indicate that the goods have been accepted for carriage;
indicate the date of issuance;
show the required airport of departure and airport of destination; and
be the original for consignor or shipper, even if the credit asks for a full set of originals.
The date of issuance is normally treated as the shipment date unless the air transport document contains a specific notation of the actual shipment date.
Merely showing a flight date elsewhere on the document does not necessarily make that the shipment date.
Transhipment: A Common Exam Trap
The word “transhipment prohibited” in an LC does not always mean that any indication of transhipment creates a discrepancy.
For example, under Article 20, a bill of lading may indicate that transhipment will or may occur despite an LC prohibition where the goods are shipped in a container, trailer or LASH barge and the entire carriage is covered by one and the same bill of lading.
Similarly, UCP 600 contains specific transhipment provisions for multimodal, air, road, rail and inland-waterway documents.
Therefore, CAIIB candidates should apply the relevant transport article, rather than relying only on the words “transhipment prohibited”.
Scrutiny of Insurance Documents
Insurance documents are principally governed by UCP 600 Article 28.
They require careful examination because discrepancies may arise from the issuer, signature, date, currency, amount, route or risk coverage.
1. Acceptable Issuer and Signature
An insurance document must appear to have been issued and signed by:
an insurance company;
an underwriter; or
their agent or proxy.
Where an agent or proxy signs, the document must indicate that the signature is for or on behalf of the insurance company or underwriter.
2. Form of Insurance Document
Acceptable documents may include:
an insurance policy;
an insurance certificate; or
a declaration under an open cover.
A cover note is not acceptable.
However, an insurance policy may be accepted in place of an insurance certificate or declaration under an open cover.
3. Originals
If the insurance document indicates that it was issued in more than one original, all originals must be presented.
4. Date of Insurance
The insurance document should be dated no later than the shipment date.
A later-dated document may nevertheless be acceptable if it shows that insurance coverage became effective from a date not later than the shipment date.
5. Currency
The insurance amount must be stated in the same currency as the credit.
6. Amount of Coverage
If the credit specifies a percentage of insurance coverage, that percentage is treated as the minimum required coverage.
Where the credit does not specify the required amount of insurance, UCP 600 provides for coverage of at least 110% of the CIF or CIP value of the goods.
Where the CIF or CIP value cannot be determined from the documents, the relevant basis is the greater of:
the amount for which honour or negotiation is requested; or
the gross value of the goods shown on the invoice.
7. Geographical Coverage
The insurance document must show coverage at least between the required place of taking in charge or shipment and the place of discharge or final destination stated in the credit.
8. “All Risks”
If the LC requires insurance against “all risks”, a document containing an all-risks notation or clause can be accepted even though the insurance document itself contains stated exclusions.
An insurance document may also contain exclusions, franchises or deductibles as permitted by Article 28.
Scrutiny of Ancillary Documents
Ancillary documents may include:
Certificate of Origin
Packing List
Weight List
Beneficiary's Certificate
Inspection Certificate
Quality Certificate
Health Certificate
Phytosanitary Certificate
Analysis Certificate
ISBP 821 provides detailed examination practices for many such documents.
Certificate of Origin
A certificate of origin should appear to relate to the invoiced goods and certify their origin.
If the credit specifies the issuer, the certificate must satisfy that requirement.
If the credit does not specify the issuer, ISBP 821 permits any entity to issue the certificate of origin.
A credit requiring a specific form of certificate of origin must be satisfied by that specified form.
The goods description on the certificate may be stated in general terms, provided it does not conflict with the credit.
Packing List
A packing list must fulfil its function by containing information relating to the packing of the goods.
If the LC states who must issue the packing list, it should be issued by that entity.
If no issuer is specified, any entity may issue it under ISBP 821.
The title itself is not always decisive. A document may have a similar title or even be untitled if its content clearly performs the function required by the credit.
Beneficiary's Certificate
Where an LC requires a beneficiary's certificate, the document should:
fulfil the certification requested by the credit;
be signed by or for the beneficiary; and
contain data that do not conflict with the credit.
The exact wording need not necessarily duplicate the LC word for word if the document clearly demonstrates that the required certification has been made.
Inspection, Quality and Similar Certificates
Where the LC requires an inspection, analysis, health, phytosanitary, quantity, quality or similar certificate, the document should fulfil the required certification function.
Where the credit specifies the issuer, it must be issued by that entity.
For a requirement concerning an action that must take place on or before shipment, the document must appropriately evidence the timing of that action.
Integrated Case Study
Assume an LC subject to UCP 600 contains the following requirements:
Commercial invoice for USD 100,000
Full set clean on-board bills of lading
Shipment from Mumbai to Singapore not later than 15 September
Insurance certificate covering 110% of invoice value
Certificate of origin issued by Chamber of Commerce
Packing list
The beneficiary presents the following documents.
Commercial Invoice
The invoice:
is issued by the beneficiary;
is made out to the applicant;
is in USD;
describes the goods consistently with the credit; and
is unsigned.
Analysis: The absence of a signature is not a discrepancy unless the LC specifically requires the invoice to be signed.
Bill of Lading
The bill of lading:
properly identifies the carrier;
is signed by an identified agent for the carrier;
evidences shipment on board at Mumbai;
shows shipment date 14 September;
shows Singapore as the port of discharge; and
contains no adverse notation concerning the goods or packaging.
Analysis: The basic requirements described above are satisfied. Shipment occurred before the latest shipment date.
Insurance Certificate
The insurance certificate:
is appropriately issued and signed;
is in USD;
provides 110% coverage;
covers the required transport route; but
is dated 17 September without any indication that coverage commenced by 14 September.
Analysis: This presents a discrepancy because the insurance document is later than shipment and does not establish that insurance was effective no later than the shipment date.
Certificate of Origin
The certificate is issued by the beneficiary instead of the Chamber of Commerce expressly required by the LC.
Analysis: This is discrepant. Where the credit specifies the required issuer, the presented certificate must satisfy that requirement.
Packing List
The document is titled “Packing Details” and clearly shows cartons, units and packing information. The LC did not prescribe a particular issuer or exact title.
Analysis: The different title does not by itself make the document discrepant because its content fulfils the packing-list function.
Practical Banking Application
A trade-finance officer should avoid checking documents in isolation.
A useful operational sequence is:
Read the LC and all accepted amendments.
Prepare the list of stipulated documents.
Identify the UCP article applicable to each document.
Check each document individually.
Compare important data across the complete presentation.
Apply ISBP 821 where relevant.
Record genuine discrepancies precisely.
Avoid raising discrepancies based only on harmless wording differences.
This approach reduces both missed discrepancies and unnecessary rejection of compliant documents.
CAIIB Exam Focus
Remember these high-value points:
Banks examine documents, not the actual goods.
Data need not be identical but must not conflict.
The commercial invoice normally need not be signed.
Invoice goods description has a stricter correspondence requirement than descriptions in other documents.
Identify the transport-document type before applying UCP rules.
“Clean” need not actually be printed on a clean transport document.
A prohibition on transhipment does not automatically make every transhipment indication discrepant.
A cover note is not an acceptable insurance document under Article 28.
Insurance normally must be effective no later than the shipment date.
Where the LC is silent on the insurance amount, the UCP 600 minimum is generally 110% of CIF or CIP value.
A specified issuer of an ancillary document matters.
An ancillary document need not necessarily carry the exact title stated in the LC if it fulfils the required function.
Common Exam Traps
Trap 1: “All Documents Must Reproduce the LC Description Exactly”
Incorrect.
Data need not be identical. They must not conflict. In documents other than the commercial invoice, goods may generally be described in broader terms without conflict.
Trap 2: “Unsigned Invoice Is Always Discrepant”
Incorrect.
UCP 600 Article 18 states that a commercial invoice need not be signed unless the LC requires otherwise.
Trap 3: “A Bill of Lading Must Contain the Word Clean”
Incorrect.
Its actual condition and notations matter. The word “clean” itself is unnecessary.
Trap 4: “Any Transhipment Violates an LC Prohibition”
Incorrect.
The applicable UCP transport article may specifically permit an indication of transhipment despite such wording.
Trap 5: “Insurance Dated After Shipment Is Always Unacceptable”
Not always.
It may still comply if the document demonstrates that insurance coverage was effective from a date no later than shipment.
Trap 6: “Cover Note Is Equivalent to Insurance Certificate”
Incorrect.
Article 28 specifically states that cover notes are not accepted.
Trap 7: “Every Ancillary Document Must Be Issued by the Beneficiary”
Incorrect.
The required issuer depends on the LC and the applicable examination rule. If the LC does not prescribe the issuer for certain documents, a different issuer may be acceptable.
Memory Technique
For integrated document scrutiny, remember I-T-I-A:
I – Invoice: issuer, applicant, currency, description
T – Transport: carrier, signature, shipment, route, originals, clean status
I – Insurance: issuer, date, currency, amount, route, risks
A – Ancillary: function, issuer, certification, consistency
Use this as a case-study checklist before deciding whether the overall presentation complies.
