Carbon Black Feed Stock (CBFS) is a dark brown to black viscous hydrocarbon oil obtained from the fractional distillation of petroleum residues. It is primarily used as the raw material for manufacturing carbon black, which is widely utilized in tyre, rubber, plastic, coating, and pigment industries.

Carbon Black Feed Stock (CBFS) is a heavy aromatic hydrocarbon fraction produced during refinery processing. It contains high carbon and aromatic content, making it ideal for the furnace black process used in carbon black manufacturing. CBFS is valued for its high BMCI (Bureau of Mines Correlation Index), which determines carbon black yield quality.

The product is commonly supplied in bulk tankers, rail wagons, or storage tanks and requires heating for pumping due to its high viscosity. Besides carbon black production, CBFS is also used in rubber process oils, agarbatti oil, fuel blending, pigments, conductive materials, and specialty chemical manufacturing.
