Products classified under HTS 2902.90.20.00
Acenaphthene
Acenaphthene is a polycyclic aromatic hydrocarbon (PAH) with the formula C12H10, consisting of naphthalene with an ethylene bridge. It falls under HTS 2902.90.20.00 as a specific cyclic hydrocarbon listed in the tariff description for separate chemically defined organic compounds.
Chrysene
Chrysene (C18H12) is a polycyclic aromatic hydrocarbon composed of four fused benzene rings. Classified under HTS 2902.90.20.00 as an explicitly listed cyclic hydrocarbon used in research and as a chemical intermediate.
p-Cymene
p-Cymene (para-cymene, C10H14) is a monoterpene aromatic hydrocarbon with methyl and isopropyl substituents on benzene. It is explicitly listed under HTS 2902.90.20.00 as a cyclic hydrocarbon used in fragrance and flavor industries.
Fluorene
Fluorene (C13H10) is a tricyclic aromatic hydrocarbon with a central five-membered ring. It qualifies under HTS 2902.90.20.00 as a named cyclic hydrocarbon used in dye manufacturing and as a fluorescent probe.
