EN 590 diesel specification explained

The standard defines limits for sulphur, cetane number, density, distillation, flash point, cold-weather behaviour, lubricity and biodiesel (FAME) content, among others. In trade, “EN 590 10 ppm” is often used as shorthand for this quality, sometimes also called ULSD (ultra low sulphur diesel).

Low sulphur content protects exhaust after-treatment systems such as particulate filters and catalytic converters and reduces sulphur emissions. A cargo offered as “EN 590 10 ppm” must prove this value in the certificate of quality from an independent laboratory.

The full list of properties and test methods is in the current edition of EN 590; contracts should refer to it and name the edition.

The temperate grades are defined by the cold filter plugging point (CFPP), from grade A (+5 °C) to grade F (–20 °C). Arctic classes have additional requirements for low temperatures. A buyer should therefore specify not only “EN 590” but also the required grade for the destination and season.

Diesel blended with biodiesel is classified under a different subheading of heading 2710. Because blending, use and national rules affect the classification, the exact code should be confirmed with the customs broker for each shipment. Diesel is also subject to excise duty in the EU, which depends on the country of consumption.

The differential reflects location, cargo size, delivery period, freight and quality details. Fixed price lists for EN 590 do not exist in genuine cargo trade; offers with prices far below the reference are a classic warning sign. We do not publish prices; they are agreed per verified transaction.

• Sampling from shore tanks and vessel tanks according to recognised standards
• Laboratory analysis of all properties required by the contract
• Quantity determination from tank measurements and temperature correction
• Retention samples kept for later disputes

A certificate is only reliable if it can be confirmed directly with the issuing inspection company.

A documented origin, verifiable through refinery, terminal and inspection documents, is a precondition for any transaction we broker. This is general information, not legal advice; applicable rules should be checked for each transaction.
