UCP 600 (Uniform Customs and Practice for Documentary Credits, 2007 revision) is the ICC rulebook that governs how letters of credit work. Combined with SWIFT MT700 messaging, it is the substrate of most international trade finance.
A documentary credit (letter of credit / LC) is an undertaking by the issuing bank to pay the beneficiary against presentation of specified documents (typically bill of lading, commercial invoice, packing list, certificate of origin). UCP 600 is the contractual framework most LCs adopt.
Issuance flow: applicant (buyer) instructs issuing bank; issuing bank issues MT700 to advising bank; advising bank notifies beneficiary (seller); seller ships and presents documents; bank examines documents under UCP 600 rules; if compliant, payment.
The "documentary" in documentary credit is critical: banks pay against documents, not the underlying goods. This is the strict-compliance doctrine — a single discrepancy in a document can void the bank's payment obligation.
UCP 600 has 39 articles covering definitions, types of credits, presentation rules, examination standards, discrepancy handling, transferability, assignment. Banks have specialised trade-finance teams that interpret these in operations.
Modern variants: standby letters of credit under ISP98 (different rule set), demand guarantees under URDG 758 (different again), MT760 vs MT700 messaging. Get the document rule and message type aligned at issuance.
For tracking: trade finance messages (MT700, MT720, MT740 series) do not use GPI tracking — they have bilateral confirmations. Your trade-finance bank can give status on demand.
The applicant (buyer) pays the issuing bank. Beneficiary pays the advising bank for advising and confirming charges (if confirmed).
A confirmation adds the advising bank's independent payment undertaking. Used when the beneficiary distrusts the issuing bank (sovereign / political risk).
For an existing trade-finance client, MT700 issuance is same-day. For first-time, includes credit approval — days to weeks.
Volume has declined as open-account trade grows. But for high-risk corridors and large transactions, LCs remain dominant. Bank Payment Obligations (BPO) tried to disrupt and largely failed.
