Gasoil D2 with 500 ppm sulfur (commonly known as Low Sulfur Gasoil) is a middle distillate refinery product. Due to its significantly reduced sulfur levels compared to 5000 ppm grades, it provides cleaner combustion and reduces wear in diesel engines. Coolak International Group supplies this specific grade tailored to the quality requirements of export destinations.
Technical Specifications and Quality
The most critical evaluation factor for this grade is the strict control of Total Sulphur, capped at 500 mg/Kg (ppm). As sulfur is reduced, maintaining the fuel's lubricity becomes essential; thus, this parameter is strictly monitored. Other key parameters include:
Cetane Index: With a minimum value of 50, it ensures shorter ignition delay and smoother operation of diesel engines.
Flash Point (PMCC): A minimum of 65°C guarantees safety during loading, transportation, and storage operations.
Viscosity and Lubricity: Kinematic viscosity ranging from 1.5 to 4.5 cSt (at 40°C) combined with a maximum lubricity wear scar of 460 µm ensures proper flow in injection systems while preventing mechanical wear.

Applications and Export Destinations
With growing environmental regulations, the demand for lower-sulfur gasoil is rising. This grade is widely used for heavy transportation fleets, industrial diesel generators, and construction machinery. A primary destination for this product is cross-border export to neighboring markets (such as Afghanistan), handling significant trade volumes due to its compatibility with regional infrastructure.
Delivery Procedures and Documentation
Supply operations at Coolak International Group are built on transparency in documentation and clear delivery protocols. Cargoes are typically allocated on an Ex-Pipe basis, complete with the necessary legal export licenses.
Due to market fluctuations, detailed commercial terms—including logistics and secure payment mechanisms (such as exchange deposits in Tehran)—are provided directly through official commercial proposals (SCO) tailored to current allocations.
