How are mixed benzene and mixed aromatics priced in China's domestic market?
Mixed benzene is a blend of benzene, toluene, xylene and minor solvent residues, typically colorless to pale yellow with a density of 0.85-0.87, and it solidifies below roughly 5C. Pricing tracks the aromatics complex rather than any single component. Chinese mixed aromatics averaged 7,644 yuan per tonne in 2022, up 37 percent year on year, with production of 371,830 tonnes against demand of 386,480 tonnes. Imports reached 204,700 tonnes versus exports of 58,200 tonnes. Because mixed benzene is a gasoline blending component, its value moves with blending margins, pure benzene inventory and toluene-xylene spreads. Low port stocks and the absence of deliverable warehouse receipts can amplify near-month price spikes, especially when downstream styrene units run hard.
