UCP 600 · ICC Uniform Customs and Practice for Documentary Credits
Documentary credits
The rules that govern almost every letter of credit worldwide. Summaries here are in my own words; always check the official ICC text for exact wording.
Based on ICC Publication No. 600 · Last reviewed October 2026
What is a letter of credit?
An LC is a bank's promise to pay the seller, provided the seller presents documents that comply with the credit's terms. The bank looks only at the documents, never at the goods. That single idea explains most of how LCs work.
- Buyer ↔ SellerSale contractParties agree that payment will be by LC.
- Applicant → Issuing bankLC applicationBuyer asks its bank to issue the credit.
- Issuing bank → Advising bankIssuanceLC is sent, usually by SWIFT MT700.
- Advising bank → BeneficiaryAdviceSeller's bank checks authenticity and advises it.
- BeneficiaryShipmentSeller ships goods and gathers the documents.
- Beneficiary → Nominated bankPresentationDocuments are presented within the period and expiry.
- BanksExaminationUp to 5 banking days to decide if documents comply.
- Issuing bank → BeneficiaryPaymentComplying documents are honoured; buyer reimburses.

Key numbers to remember
The figures that come up again and again, in daily work and in CAIIB and CDCS exams.
Reading an MT700
An LC usually arrives as a SWIFT MT700. These are the fields I check first, and what to look for in each.
What to check on each document
Commercial invoice
- Appears to be issued by the beneficiary
- Made out in the name of the applicant
- Same currency as the credit
- Goods description corresponds with the LC
- Need not be signed unless the LC asks
Bill of lading
- Names the carrier and is signed by the carrier, master or a named agent
- Shows goods shipped on board, with a date
- Port of loading and discharge as stated in the LC
- Full set of originals, if issued in more than one
- Clean: no clause showing defective goods or packing
Insurance document
- Issued and signed by an insurer, underwriter or their agent
- Dated no later than shipment, unless cover starts from shipment
- At least 110% of the CIF or CIP value if the LC is silent
- Same currency as the credit
- All originals presented if more than one was issued
Draft, origin certificate and others
- Draft must not be drawn on the applicant
- Amount within the credit amount and tolerance
- Certificate issued by the party the LC names
- Data does not conflict with other documents
- Content appears to fulfil the document's function
Where presentations usually go wrong
Before you present: an exporter's checklist
Most discrepancies are avoidable. These are the checks that save the most trouble.
ISBP 821 · International Standard Banking Practice
Examination practice
UCP 600 says documents must comply with "international standard banking practice". ISBP is where the ICC writes that practice down, document by document.
Based on ICC Publication No. 821 · Last reviewed October 2026
What it is
A companion to UCP 600, published by the ICC Banking Commission. ISBP 821 replaced ISBP 745. It does not change UCP 600; it explains how examiners apply it.
How it is organised
General principles first, then a section for each document: drafts, invoices, transport documents, insurance, certificates of origin, packing and weight lists, beneficiary's certificates and inspection certificates.
Practice points examiners use every day
URDG 758 · Uniform Rules for Demand Guarantees
Demand guarantees
Rules for guarantees and counter-guarantees payable on a complying demand, such as performance, advance payment, bid and retention guarantees.
Based on ICC Publication No. 758 · Last reviewed October 2026
| Documentary credit (UCP 600) | Demand guarantee (URDG 758) | |
|---|---|---|
| Purpose | Primary means of payment | Security if the applicant does not perform |
| Expected outcome | Bank pays in the normal course | Bank pays only if something goes wrong |
| Who presents | Seller, with shipping documents | Beneficiary, with a demand and supporting statement |
| Examination time | 5 banking days | 5 business days |
Key provisions
URC 522 · Uniform Rules for Collections
Documentary collections
Banks pass documents from seller to buyer and release them against payment or acceptance. Unlike an LC, no bank promises to pay.
Based on ICC Publication No. 522 · Last reviewed October 2026
Documents against payment
The buyer gets the documents, and so the goods, only after paying. Usually at sight.
Documents against acceptance
The buyer gets the documents after accepting a bill of exchange to pay at a future date. The seller carries the credit risk until then.
The parties
Key provisions
URR 725 · Uniform Rules for Bank-to-Bank Reimbursements
Bank reimbursements
When a nominated bank pays under an LC, it often claims its money from a third bank, not the issuing bank. URR 725 governs that claim.
Based on ICC Publication No. 725 · Last reviewed October 2026
- Issuing bank → Reimbursing bankAuthorisationIssuing bank authorises the reimbursing bank to pay claims under the credit.
- Claiming bank → Reimbursing bankClaimAfter paying the beneficiary, the nominated bank sends its claim.
- Reimbursing bank → Claiming bankPaymentReimbursing bank pays and debits the issuing bank.
Key provisions
Incoterms® 2020 · ICC rules for the use of trade terms
Delivery terms
Eleven three-letter terms that settle who arranges transport and insurance, who clears customs, and where risk moves from seller to buyer. The term chosen shapes which documents the LC asks for.
Based on ICC Incoterms® 2020 · Last reviewed October 2026
Any mode of transport
EXW, FCA, CPT, CIP, DAP, DPU, DDP. Use these for containers and multimodal shipments.
Sea and inland waterway only
FAS, FOB, CFR, CIF. Best for bulk cargo loaded directly onto a vessel.
Terms and the LC documents that usually go with them
| Term | Risk passes to buyer | Seller pays main freight | Seller insures | Typical LC transport / insurance documents |
|---|
Under FCA, the parties can agree that the buyer's carrier issues an on-board bill of lading to the seller, which helps when an LC requires one.
ISP98 · International Standby Practices
Standby credits
A standby LC works like a guarantee: the bank pays only if the applicant fails to perform. UCP 600 can apply to standbys, but ISP98 was written specifically for them.
Based on ICC Publication No. 590 · Last reviewed October 2026
Where standbys are used
Common in the US and in cross-border lending, where banks there have traditionally issued standbys instead of guarantees. Used to back loan repayment, performance, advance payments and trade payables.
Why separate rules
Many UCP 600 articles deal with shipping documents that a standby never sees. ISP98 deals directly with demands, statements of default and the realities of standby practice.
Key provisions
eUCP Version 2.1 · Supplement to UCP 600
Electronic presentation
The eUCP adds rules for presenting electronic records, alone or together with paper documents, under a credit subject to UCP 600.
Based on the ICC eUCP Version 2.1 · Last reviewed October 2026
How it works with UCP 600
The credit must state that it is subject to the eUCP. UCP 600 still applies, and the eUCP adds or adjusts rules where electronic records are involved. Where they conflict, the eUCP prevails.
Why it matters
Electronic bills of lading and digital trade platforms are growing. Banks and exporters need clear rules on when an electronic presentation is complete and what happens if a record cannot be read.

Prepayment savings

Assumes you keep paying the same EMI, so the tenure shortens.
Trade finance
LC date calculator
Work out the last day to present documents, the bank's examination deadline, and whether shipment was in time.
If the LC is silent, UCP 600 Art. 14(c) sets 21 calendar days after shipment. Art. 29(a) moves a last day that falls on a bank holiday to the next banking day.
Timeline
Trade finance
Usance bill maturity
The due date of a usance draft, adjusted for bank holidays at the place of payment.
Under ISBP, "from" and "after" a date both start counting on the following day, so 90 days from 20 October matures on 18 January. If maturity falls on a day the bank is closed, payment is due on the next banking day.
Savings and loans
SIP calculator
One possible outcome of a monthly investment at a steady rate of return.
Returns from market-linked funds are not guaranteed. This shows one possible outcome at a steady rate.
