Traders often ask for an SBLC when the supplier actually needs a documentary letter of credit, or they ask for an LC when the real gap is performance or payment support on a term contract. For Jet A-1 and EN590, that mix-up is expensive in practice. The supplier will not load, the bank will not issue the wrong instrument, and time is usually the one thing the cargo does not have.

The money page on [LC and SBLC structures for refined petroleum products](https://www.financely.io/lc-and-sblc-structures-for-refined-petroleum-products?ref=blog.financely.io) covers instrument choice and mandate packaging across refined products, including mazut. This guide stays with Jet A-1 and EN590, which are the distillate grades most often moved under documentary credits. Financely is an advisor and arranger. We do not issue LCs or SBLCs, and we do not lease or monetize standby credits.

## What the supplier is actually asking for

If the supplier must be paid against shipping documents and an inspection certificate for a named cargo, the instrument is a documentary LC, usually under UCP 600\. The credit should name the specification, ASTM D1655 or DEF STAN 91-091 for Jet A-1, EN 590 for diesel, the quantity tolerance, the ports or the terminal, the latest shipment date, and the exact documents. Quality and quantity certificates should be issued by an independent inspector appointed in a way the credit recognizes. A certificate generated by the seller is not the same thing.

If the supplier already ships on open account, or under a term contract, and wants a safety net if the buyer fails to pay or fails to take, a standby letter of credit may be the right support. The standby should state the obligation it supports, the rule set, usually ISP98, and the documents required for a demand. It does not replace the cargo documents, and it does not prove that Jet A-1 or EN590 is in the tank. For a wider walk-through of fuel LC practice, see the existing [LC financing guide for AGO, jet fuel, gasoline and fuel oil](https://blog.financely.io/lc-financing-for-ago-jet-fuel-gasoline-and-fuel-oil-trades/).

## Typical distillate flows

- A single FOB or CIF cargo of EN590 or Jet A-1, paid by a sight or usance documentary LC, with independent Q&Q at load, and sometimes a further check at discharge. This is the standard shape.
- A repeat monthly purchase, where a revolving documentary LC or a series of credits may be cleaner than a fresh negotiation every time, provided the applicant has the issuing capacity.
- A terminal-to-buyer EN590 sale, where title may move on tank documents rather than an ocean bill of lading. The credit, if used, has to call for the documents that actually evidence that transfer. See [EN590 trade finance for terminal-to-buyer transactions](https://blog.financely.io/en590-trade-finance-for-terminal-to-buyer-transactions/) and [title transfer and release procedures for fuel in tank](https://blog.financely.io/title-transfer-and-release-procedures-for-fuel-in-tank/).
- An airport or into-plane Jet A-1 supply, where a standby or a term LC may sit behind a supply contract, while individual liftings are invoiced and reconciled against inspected receipts. See [jet fuel trade finance for airport supply contracts](https://blog.financely.io/jet-fuel-trade-finance-for-airport-supply-contracts/).

## Drafting points that cause discrepancies

The product description in the LC must match the SPA. Jet fuel is not precise enough when the buyer needs Jet A-1 to a named checklist. Diesel is not precise enough when the buyer needs EN590 with a stated winter grade. Quantity tolerances, latest shipment dates and inspection wording should also match. A credit that requires a clean on-board bill of lading cannot be used, without amendment, for an in-tank transfer that will never have that bill.

Confirmation, tolerance, partial shipments and transshipment need to be decided on purpose, not copied from an old template. Origin, vessel and counterparty screening still apply, as set out in [KYT checks for oil, gas and refined fuel trades](https://www.financely.io/kyt-checks-for-oil-gas-and-refined-fuel-trades-before-trade-finance?ref=blog.financely.io). Discount offers that demand an LC in favor of an unverified seller should be read against [discount EN590 and Jet A-1 scams](https://www.financely-group.com/discount-en590-jet-a1-petroleum-scams?ref=blog.financely.io) and [fake petroleum seller scams](https://blog.financely.io/fake-petroleum-seller-scams-sco-icpo/).

## Confirmation, discrepancies and time

A seller of Jet A-1 or EN590 will often want a confirmed credit, especially if the issuing bank is not a name the seller's bank will take. Confirmation is a separate undertaking, with its own conditions, and it has to be requested on purpose in the application. It does not repair a weak inspection plan or a product description that does not match the SPA.

Most delays in these trades are documentary. A quality certificate that names the wrong standard, a bill of lading that does not match the quantity tolerance, or an in-tank deal forced into a marine-document credit, will produce a discrepancy. The time spent agreeing the document list before issuance is usually cheaper than an amendment after the vessel has been nominated. If the parties already know the credit will need to be [discounted](https://www.financely.io/lc-discounting-and-finance-for-petroleum-trades?ref=blog.financely.io) or [forfaited](https://www.financely.io/refined-petroleum-product-letters-of-credit-and-forfaiting?ref=blog.financely.io) after presentation, say so early, because the form of the credit can affect whether that is even possible.

## How to take the question to Financely

Bring the SPA, the draft LC or SBLC text if you have one, the specification, the inspection plan and a clear statement of what the supplier has actually demanded. Submit it through [deal submission](https://www.financely.io/deal-submission?ref=blog.financely.io). We will tell you if the instrument does not match the trade, and we will not take a leased-SBLC story to a bank.

## Frequently Asked Questions

### Can I use an SBLC instead of a documentary LC to buy EN590 or Jet A-1?

Only if the supplier has agreed to that and the standby actually supports the obligation the supplier cares about. Most cargo suppliers want a documentary LC that pays against compliant documents, not a standby that pays only after a default.

### Which rules should the instrument cite?

Documentary LCs almost always cite UCP 600\. Standbys often cite ISP98\. The rule set must be written into the instrument and aligned with the contract. A mismatch between those two texts is expensive, because the supplier and the issuing bank will read the instrument that is actually issued.

### Does Financely issue the LC or the SBLC?

No. Financely is an advisor and arranger only. It does not issue letters of credit or SBLCs, and it does not lease or monetize standby credits. A bank or another capital provider issues the instrument if it accepts the applicant and the file. Financely will not take a leased-SBLC story to a bank.

### What if the trade is an in-tank transfer, not a voyage?

The instrument has to call for tank receipts, title documents and release instructions that match the terminal, not a marine bill of lading that will never exist. See the guide to title transfer and release procedures for fuel in tank.
