Understanding DLC vs SBLC: Securing Your First Petroleum Transaction

Two instruments, one goal

A Documentary Letter of Credit (DLC) is a payment mechanism: the bank pays against compliant shipping documents. A Standby Letter of Credit (SBLC) is a guarantee: the bank pays only if the buyer defaults.

Refineries and merchant exporters typically prefer DLCs for cargo trades because payment is tied directly to the Bill of Lading, Commercial Invoice and Q&Q Certificate.

UCP 600 compliance matters

Every instrument should be issued under ICC UCP 600 rules and confirmed by a Top-50 global bank. This single detail eliminates most documentary disputes before they start.

The practical sequence

Inquiry, Soft Corporate Offer, ICPO, then the Sales & Purchase Agreement — only then should the instrument be issued. Issuing banking instruments before the SPA is the most common first-timer mistake.
