2707.50.00.00 - Other aromatic hydrocarbon mixtures of which 65 percent or more by volume (including losses) distills at 250˚C by the ISO 3405 method (equivalent to the ASTM D 86 method)

Category 2707.50.00.00 encompasses other aromatic hydrocarbon mixtures derived from the distillation of high-temperature coal tar, or similar products where aromatic constituents outweigh non-aromatic ones. The defining characteristic of these mixtures is their distillation behavior: 65 percent or more by volume, including losses, must distill at 250°C, as determined by the ISO 3405 method (or its equivalent, ASTM D 86). This criterion distinguishes these complex mixtures from more specifically defined aromatic hydrocarbons.

Unlike the preceding sibling categories, which are reserved for pure benzene (2707.10), toluene (2707.20), xylenes (2707.30), and naphthalene (2707.40), this category serves as a residual for aromatic mixtures that do not meet the specific purity or identity requirements of those headings. These products are often characterized by their complex composition, containing a variety of aromatic compounds beyond those individually listed.

As this is a leaf node in the HTS structure, there are no further subcategories under 2707.50.00.00. Therefore, the focus for classification within this heading is on the precise adherence to the distillation requirement and the confirmation that the material consists of aromatic hydrocarbon mixtures where the weight of aromatic constituents exceeds that of non-aromatic constituents, and is not elsewhere specified in the 2707 chapter.
