Other Aromatic Hydrocarbons — 65% or More Distilling at 250°C (ASTM D 86)

Defined by a specific distillation test — at least 65% by volume (including losses) must distill at or below 250°C by the ASTM D 86 method — the aromatic hydrocarbon mixtures in 2707500000 are heavier coal tar fractions used as process solvents, carbon black feedstocks, and specialty fuel blendstocks. The ASTM D 86 distillation threshold is the operative classification criterion, distinguishing these blends from lighter fractions classified elsewhere in heading 2707. Canada leads US imports under this heading, followed by Italy and the Netherlands, with South Korea and Argentina also among suppliers.
