Heavy End refers to the dense, highly viscous hydrocarbon fraction that remains once lighter products—such as gasoline, kerosene, and diesel—are removed during crude oil refining. This material contains complex, high–molecular weight structures, including asphaltenes, resins, paraffinic chains, and various naphthenic compounds.

Distinguished by its elevated boiling range and thick, dark appearance, Heavy End plays a significant role in downstream petrochemical and industrial sectors. It serves as a key feedstock for the manufacture of asphalt and bitumen, heavy fuel oils (HFO), specialty lubricants, and a wide spectrum of high-performance chemical intermediates.

As global energy consumption continues to rise, Heavy End is increasingly recognized as a valuable resource rather than a low-grade residue. It is widely used in marine bunker fuel blending, bitumen production, and as a reliable input for catalytic cracking units. Baniar Petrochemical Company provides Heavy End products that meet stringent international quality specifications, ensuring consistent performance across diverse industrial applications.
