Import Cst 280 And 380 Fuel Oil — Buy in Bulk from Supplier in United Kingdom

CST 280 and CST 380 are grades of fuel oil offered by Arsignum Ltd., a UK‑based trading company. The oils are sourced from refineries in Iran and can be supplied on FOB or CIF terms using the supplier’s own vessels. CST 280 corresponds to a medium‑viscosity fuel oil, while CST 380 is a higher‑viscosity variant used where greater lubricity is required. The listing does not provide exact batch numbers, pricing or minimum order quantities.

Typical specifications for CST 280 include a kinematic viscosity of 28 - 32 cSt at 40 °C, a flash point above 60 °C, sulfur content below 0.5 % by mass and a pour point around - 6 °C. CST 380 normally exhibits a viscosity of 45 - 55 cSt at 40 °C, a flash point also above 60 °C, sulfur content under 0.5 % and a calorific value near 42 MJ kg⁻¹, which is standard for heavy fuel oils. Both grades meet the ASTM D445 viscosity standard and the EN 590 fuel oil specification for marine use. Buyers should request a recent analysis certificate to confirm these typical values for the specific shipment.

These fuel oils are commonly used in marine bunkering, power‑generation turbines and large‑scale industrial boilers. Importers should verify the supplier’s export licence, the latest laboratory test report and the vessel’s loading plan before finalising the purchase. As the listing does not disclose lead time, payment method or exact Incoterms beyond FOB/CIF, those details must be negotiated directly with Arsignum Ltd.
