The bank sees the documents, not the goods.
A letter of credit is the SWIFT MT700 message sent by the issuing bank, and it is read by field number. For the party running the shipment, eight fields come first: 31D expiry, 41a availability, 43P/43T partial shipment and transhipment, 44E/44F ports, 44C latest shipment date, 46A documents required, 47A additional conditions, 48 presentation period. The bank never sees the goods; it examines whether the documents presented comply with the credit, with UCP 600 and with each other.
How the text is built: MT700 fields
A credit is issued between the issuing bank and the advising bank as a standard SWIFT message, so it arrives with the same field numbers anywhere in the world. The table lists the fields that concern the shipment, in order. "M" is mandatory, "O" optional, "C" conditional.
| Field | Name | M/O | What it means for the shipment |
|---|---|---|---|
| 40A | Form of documentary credit | M | IRREVOCABLE; TRANSFERABLE if it can be transferred. Under UCP 600 every credit is irrevocable. |
| 20 | Documentary credit number | M | Quoted on the shipping instruction and the invoice. |
| 31C | Date of issue | O | Not the start of any clock; clocks start from the shipment date. |
| 40E | Applicable rules | M | "UCP LATEST VERSION" = UCP 600. If eUCP is stated, electronic presentation is possible. |
| 31D | Date and place of expiry | M | The latest date and the place for presenting documents (advising bank or issuing bank). |
| 50 / 59 | Applicant / beneficiary | M | Buyer and seller. Names and addresses on the documents must not conflict with these. |
| 32B | Currency and amount | M | The invoice may not exceed it; insurance must be in this currency. |
| 39A | Percentage credit amount tolerance | C | E.g. 05/05 → ±5% on amount and quantity. |
| 41a | Available with … by … | M | BY PAYMENT (sight), BY DEF PAYMENT (deferred), BY ACCEPTANCE (draft accepted), BY NEGOTIATION. |
| 42C / 42a | Drafts at … / drawee | C | "AT SIGHT" or e.g. "90 DAYS AFTER B/L DATE"; the bill of lading date sets the tenor. |
| 43P | Partial shipments | O | ALLOWED / NOT ALLOWED. If blank, UCP 600 Art. 31: allowed. |
| 43T | Transhipment | O | ALLOWED / NOT ALLOWED. For containers there is the Art. 20(c) exception — below. |
| 44A / 44E | Place of receipt / port of loading | O | The port name on the bill of lading must be consistent with this field. |
| 44F / 44B | Port of discharge / final destination | O | Likewise. |
| 44C / 44D | Latest date of shipment / shipment period | C | The "on board" date on the bill of lading may not be later than this. |
| 45A | Description of goods | O | Corresponding wording on the invoice; general terms that do not conflict on other documents (Art. 14(e), 18(c)). |
| 46A | Documents required | O | List of documents, number of originals (e.g. "FULL SET 3/3 ORIGINAL"), issuer. |
| 47A | Additional conditions | O | Where most discrepancies come from: container number, marks, vessel age, order of presentation and other special requirements. |
| 71D | Charges | O | Which bank charges are for whose account (71B in older messages). |
| 48 | Period for presentation | O | Days after the shipment date. If blank, 21 calendar days (Art. 14(c)). |
| 49 | Confirmation instructions | M | CONFIRM / MAY ADD / WITHOUT. Under a confirmed credit a second bank also undertakes to pay. |
The field list comes from the SWIFT MT700 standard; the mandatory/optional marks are SWIFT's own. If your bank forwarded the text in a non-SWIFT format, look for the same headings — the content does not change.
The eight fields to read first
When a credit arrives the whole text has to be read, but the shipment plan is built from eight fields. The order matters: time first, then place, then documents.
- 31D — Expiry
- The documents must be at the bank by this date at the latest. The vessel may have sailed well before; if expiry passes while the documents are with the courier, the presentation is late.
- 44C — Latest shipment date
- The "on board" date on the bill of lading may not be later than this. When booking, think of the date the on-board notation will be dated, not the vessel's ETD; if the vessel slips a week the field is breached.
- 48 — Period for presentation
- How many days after the shipment date the documents must be presented. If blank, 21 calendar days. If the gap between 44C and 31D is shorter than this period, the credit is flawed from the day it is issued.
- 43P / 43T — Partial shipments and transhipment
- If two containers go on two vessels, read 43P. If transhipment is prohibited, read 43T — but for containerised cargo read the Art. 20(c) exception.
- 44E / 44F — Ports
- The port of loading and discharge on the bill of lading must be consistent with the names in these fields. "Any Turkish port" gives room; "Ambarlı" makes a loading at Asyaport a possible discrepancy.
- 46A — Documents required
- How many originals, who issues, what they must say. "Ocean bill of lading issued by carrier" excludes a forwarder's house bill; "consigned to order of [bank]" dictates the shipping instruction.
- 47A — Additional conditions
- Free text, and the source of most discrepancies: container and seal numbers on the documents, vessel age, class or flag, how many days for couriering documents. A condition that cannot be met means the credit is amended, not ignored.
- 41a — Availability
- Sight payment, deferred, acceptance or negotiation. If deferred, the tenor in 42C runs from the bill of lading date: the later the loading, the later the collection.
Ask for the credit text before the booking, not after. 44C, 43T, 44E and 46A decide which vessel, which port and which bill of lading the booking is made with. A booking made before the text arrives is a shipment being fitted to a credit after the fact.
If you see a condition that cannot be met, change the credit, not the shipment. An amendment (MT707) needs the applicant's and the issuing bank's consent and takes time; the closer to loading, the weaker your position.
If you sell FCA you will clash with a credit that calls for an "on board" bill of lading; write the Incoterms® 2020 on-board notation option into the contract — detail on the FOB or FCA page.
Transport document articles: UCP 600 Art. 19–24
UCP 600 writes a separate article for each transport document. The four the shipping side meets most:
- Art. 20 — Bill of lading
- Must show the carrier's name and be signed by the carrier, the master or a named agent for either. Must carry an "on board" notation showing the goods were loaded on the named vessel, with its date; that date is the date of shipment, not the issue date. Must show carriage from the port of loading to the port of discharge stated in the credit.
- Art. 20(c) — Transhipment exception
- If the entire carriage is covered by one bill of lading, the document may indicate that transhipment will or may take place. Even where the credit prohibits transhipment, a bill of lading indicating it is acceptable if the goods are shipped in a container, trailer or LASH barge. On container shipments, 43T "NOT ALLOWED" is therefore not a bar on its own.
- Art. 23 — Air transport document
- The date of issuance is deemed the date of shipment, unless the document carries a specific notation of the actual flight date, which then prevails. Because an air waybill does not represent the goods, it cannot be made out "to order".
- Art. 24 — Road, rail and inland waterway documents
- CMR and CIM notes must show the carrier's name and signature or stamp; the date of receipt or dispatch is deemed the shipment date. If the document does not state the number of originals, the copy presented is sufficient.
There is also Art. 19: the multimodal transport document. A document covering at least two modes — such as a FIATA FBL — is accepted only if the credit allows it. For bill of lading types and the endorsement chain see the bill of lading page.
Time limits: 5 days, 21 days, expiry
- Examination period — Art. 14(b): a maximum of five banking days following the day of presentation. The bank decides on compliance within this period; if it refuses, under Art. 16 it lists all discrepancies in a single notice.
- Presentation period — Art. 14(c): if the credit states no period, the transport document must be presented within 21 calendar days after the date of shipment, and in any event no later than the expiry date. If field 48 states a period, that period applies.
- Expiry — 31D: the last day and place of presentation. If the gap between expiry and the latest shipment date is shorter than the presentation period, the credit is effectively unusable; ask for an amendment as soon as it arrives.
- Data consistency — Art. 14(d): data on the documents need not be identical but must not conflict. "12 pallets" on the invoice and "11 pallets + 1 carton" on the packing list is a conflict.
Insurance and tolerances
Insurance document — Art. 28. Must be issued and signed by an insurance company, an underwriter or their agent; its date may not be later than the date of shipment (unless it shows cover effective from a date no later than shipment). It must be in the currency of the credit. If the credit states no percentage, the minimum cover is 110% of the CIF or CIP value of the goods; where that value cannot be determined from the documents, 110% of the amount for which honour is requested or of the invoice value, whichever is greater.
Tolerances — Art. 30. "About" or "approximately" before the amount, quantity or unit price allows ±10%. If the quantity is not stated in packing units or individual items and the amount drawn does not exceed the credit amount, a ±5% quantity tolerance applies automatically. This saves bulk cargo; it does not apply to packaged goods.
Partial shipments — Art. 31. Allowed unless the credit prohibits them. Several bills of lading on the same vessel and voyage — even with different loading dates and ports — are one presentation, not a partial shipment.
Pre-shipment checklist
These are the checks we run before booking; each maps to an article of UCP 600.
- Vessel choice against 44C. A vessel whose on-board date will not exceed 44C; cut-off a week earlier.
- Shipping instruction against 46A. Consignee and notify fields, "freight prepaid/collect", number of originals, carrier signature requirement. Is a house bill accepted?
- Port names against 44E/44F. The port name on the bill must not conflict with the credit's spelling; adding a UN/LOCODE is not a problem.
- 45A and Art. 18(c). Goods description on the invoice corresponding with the credit; general terms on the bill and packing list, but no conflict.
- 47A line by line. Container and seal numbers, marks, vessel restrictions, document order. Amendment for anything that cannot be met.
- Shipment plan against 43P/43T. Partial shipment and transhipment permissions; the Art. 20(c) note for containers.
- Insurance, Art. 28. 110% on CIF/CIP sales, currency, date, clause level (Incoterms® 2020: ICC (C) minimum under CIF, ICC (A) under CIP).
- Calendar. Loading → collecting documents → presentation: field 48 or 21 days; expiry in 31D; courier time.
When it goes wrong
The vessel slipped, 44C passed
The booking was made on the ETD; the vessel loaded a week late and the on-board date exceeded the latest shipment date. The document is discrepant; payment depends on the applicant's acceptance.
Do this: choose a vessel with at least a week's margin to 44C; once a delay is known, ask for an amendment before loading.
The port name conflicts with the credit
The credit says "Istanbul, Turkey", the bill of lading says "Ambarli", or the reverse. Banks may treat the data conflict as a discrepancy.
Do this: use the credit's spelling in the shipping instruction; write both if needed.
Documents exceeded 21 days
Field 48 blank; presentation made 25 days after the shipment date. Late under Art. 14(c) — even though the credit has not expired.
The credit calls for a bill of lading, a sea waybill is presented
Open-account habits led to a sea waybill. If 46A says "full set 3/3 original bill of lading", the presentation is discrepant; the document types sit in separate sections of ISBP.
Insurance issued at 100%
The policy was issued for the invoice amount. If the credit states no percentage, Art. 28 requires a minimum of 110%; the document is discrepant.
Frequently asked
What is a discrepancy, and what happens?
When the bank finds that the documents presented do not comply with the credit or UCP 600, it refuses to honour and, under Art. 16, lists all discrepancies in a single notice. From there, three routes: the documents are corrected and re-presented within the time limits; the applicant waives the discrepancies and the bank pays; or the documents are returned and the seller has to settle with the buyer outside the credit.
We give no percentage for discrepancies at first presentation on this page; we could not find a current statistic whose source we could verify. That banks frequently refuse first presentations is stated in the ICC's own training publications.
Does the forwarder prepare the bill of lading for the bank?
The carrier (or its agent) issues the bill of lading; the forwarder prepares the shipping instruction according to the credit and checks the draft before loading. Our job is to compare the draft bill line by line against 46A, 44E/44F and 47A.
The forwarder's own bill (house bill) is accepted only if the credit allows it; not if it says "issued by carrier".
Is UCP 600 still in force?
Yes. UCP 600 is the ICC's 2007 revision and the current rule set applied to documentary credits; "UCP LATEST VERSION" in field 40E of the MT700 refers to it. The examination practice standard banks use is ISBP 821. For electronic presentation there is eUCP version 2.1.
What difference does confirmation make?
If field 49 says "CONFIRM", the advising bank adds its own undertaking and pays against a complying presentation regardless of the issuing bank's country and bank risk. "MAY ADD" means confirmation depends on the beneficiary's request and cost; "WITHOUT" means no confirmation.
