EN590 Diesel: A Buyer's Guide to Specifications and Terms

EN590 is the European standard for automotive diesel, and "EN590 10ppm" has become the default reference for buyers sourcing road-grade diesel internationally. Understanding what it covers — and how the product is actually traded — protects buyers from both quality problems and the fraud that surrounds fuel trading.

What EN590 actually specifies

EN590 sets limits on the properties that determine how diesel behaves in a modern engine: sulphur content, cetane number, density, flash point and cold-flow behaviour. The "10ppm" refers to ultra-low sulphur — the standard for most markets with emissions regulations. Some regions still accept 50ppm; know which yours requires before you buy.

How it trades — and where deals go wrong

Refined fuels move in vessel and coastal parcels on terms such as FOB, CIF or CFR. The legitimate market runs on verified allocation and full documentation. The illegitimate market runs on endless "soft offers" and requests for buyer commitment before any proof of product — a pattern experienced buyers learn to walk away from.

• A clear specification — EN590 10ppm (or 50ppm), stated explicitly.
• Independent inspection at the load port.
• Documentary payment matched to the shipping documents.
• Verified allocation and proof of product before any buyer commitment.

Diesel is a commodity where the specification is well defined and the fraud is well known. Insist on documentation and inspection, and be willing to walk away from offers that skip them.
