UCP 600 explained: the letter of credit rules to check
By the Vanguard Verify desk · Published 2026-10-26 · Updated 2026-11-04
Short answer: UCP 600 is the International Chamber of Commerce's set of rules for documentary credits (letters of credit), ICC Publication No. 600, in force since 1 July 2007. It has 39 articles. It applies only when the credit itself says it is subject to UCP 600. It governs how banks examine documents and when they must pay. It is not a licence, a registration or a guarantee that a deal is genuine.
The UCP 600 rules traders ask about most
| Article | What it says (summary) | Why it matters |
|---|---|---|
| Art. 1 | The rules apply when the text of the credit expressly incorporates them | No reference in the credit means UCP 600 does not apply automatically |
| Art. 3 | A credit is irrevocable even if it does not say so | "Revocable LC" offers are not UCP 600 credits |
| Art. 4 and 5 | The credit is separate from the sales contract, and banks deal with documents, not goods | Your protection depends on the documents the credit asks for |
| Art. 14(b) | Banks have a maximum of five banking days after the day of presentation to decide whether documents comply | Sets the timeline for payment or refusal |
| Art. 14(c) | Original transport documents must be presented within 21 calendar days after shipment, and never later than expiry | A common reason for discrepancies |
| Art. 16 | A bank that refuses must send one notice listing every discrepancy | A bank cannot raise new discrepancies later |
| Art. 30 | "About" or "approximately" allows a 10% tolerance | Affects quantity and amount in bulk cargo |
| Art. 38 | A credit can be transferred only if it is expressly stated to be "transferable" | Matters for intermediaries and brokers |
How to check a credit that claims to be under UCP 600
- Read the applicable rules line. On a SWIFT MT700 the credit states its applicable rules, usually "UCP LATEST VERSION". See DLC MT700 explained.
- Confirm it came through the bank channel. A real credit reaches your bank (the advising bank) by authenticated SWIFT, not as a PDF from a broker. Ask your own bank to confirm it was received and authenticated.
- Check the documents it requires. List every document, its issuer and any wording it must contain. Clauses that only the buyer can satisfy, such as an inspection certificate "signed by the applicant", give the buyer control over payment.
- Check the dates. Compare the latest shipment date, the 21-day presentation period and the expiry date against your real loading schedule.
- Check the issuing bank. Look up its BIC and its regulator. If you have doubts about its credit risk, ask for confirmation by a bank you trust. See confirmed letter of credit explained.
Red flags
- "ICC 600" or "UCP 600" is used as a stamp of authenticity on an NCNDA, an ICPO or a "leased" instrument. UCP 600 governs documentary credits, not broker paperwork.
- You are told an MT799 is a "UCP 600 letter of credit". An MT799 is a free-format message and is not a credit.
- The credit is described as "revocable" or "cash-backed" as if those were UCP 600 terms.
- You are asked to pay a fee before the issuing bank will "release" a UCP 600 credit.
- The credit is offered only as a scanned image with no advising bank.
UCP 600 vs ISP98 and URDG 758
UCP 600 is written for commercial documentary credits, although standby credits can also be issued under it. ISP98 was written specifically for standby letters of credit. URDG 758 covers demand guarantees. Which set of rules applies changes how a demand is examined. See standby documentary credit and ISP98.
