Mazut M100

GOST 10585-99 Heavy Fuel Oil for Industrial and Marine Use

Mazut M100 is a heavy residual fuel oil derived from the atmospheric distillation of crude petroleum. Produced primarily in Russian and CIS refineries, it conforms to the GOST 10585-99 standard and is one of the most traded heavy fuel products in global commodity markets. Its high energy density and relatively low cost per BTU make it an attractive option for large-scale power generation, district heating systems, and industrial boiler operations.

Intentions Institute Inc. sources Mazut M100 directly from refinery-gate suppliers in Russia, Kazakhstan, and Turkmenistan, with established logistics corridors through Black Sea, Baltic, and Caspian ports. Our supply chain is structured to handle large parcel sizes, typically ranging from 25,000 to 100,000 metric tons per shipment, with the capacity to arrange back-to-back deliveries for continuous supply requirements.

Mazut M100 is also used extensively as marine bunker fuel in regions where IMO 2020 low-sulfur regulations permit its use with exhaust gas cleaning systems (scrubbers). For power plants and industrial facilities operating in developing economies, it remains a primary fuel source due to its cost advantages over lighter distillates and natural gas.

We offer supply on FOB (Novorossiysk, Ventspils, Aktau) and CIF terms to ports worldwide. Our trading desk can structure both spot and term contract arrangements with performance guarantees, independent inspection at load port, and full documentation including certificates of origin, quality, and quantity.
