2902.90.20.00 - Acenaphthene, chrysene, cymene, dimethylnaphthalenes, fluoranthene, fluorene, indene, mesitylene, methylanthracene, methylnaphthalene, phenanthrene and pyrene

This HTS category, 2902.90.20.00, specifically covers a group of polycyclic aromatic hydrocarbons (PAHs) and substituted aromatic hydrocarbons. It includes compounds such as acenaphthene, chrysene, cymene, dimethylnaphthalenes, fluoranthene, fluorene, indene, mesitylene, methylanthracene, methylnaphthalene, phenanthrene, and pyrene. These are organic compounds characterized by their fused ring structures and are often derived from coal tar or petroleum.

This classification distinguishes itself from its sibling categories by its specific listing of individual aromatic compounds. For instance, while 2902.90.10.00 covers pseudocumene and 2902.90.30 encompasses broader categories of alkylbenzenes and polyalkylbenzenes, this node focuses on a more defined set of PAHs and specific methyl-substituted naphthalenes and anthracenes. Similarly, it differs from 2902.90.40.00, which specifically lists anthracene and 1,4-Di-(2-methylstyryl)benzene, and 2902.90.60.00, which is limited to biphenyl in flake form.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification into this heading relies solely on accurately identifying the presence of the listed chemical compounds. Importers and exporters must ensure that the goods they are declaring precisely match the chemical names provided in the description to ensure correct customs processing.
