2904.20.15.00 - p-Nitro-o-xylene

This classification covers p-Nitro-o-xylene, a derivative of hydrocarbons characterized by the presence of a nitro group and two methyl groups on a benzene ring, specifically with the nitro group positioned para to one methyl group and ortho to the other. It falls under the broader category of sulfonated, nitrated, or nitrosated hydrocarbon derivatives, specifically those containing only nitro or nitroso groups.

Within its sibling categories, p-Nitro-o-xylene is distinct from p-Nitrotoluene (2904.20.10.00) by the presence of an additional methyl group on the benzene ring. It is also differentiated from Trinitrotoluene (2904.20.20.00) and artificial musks like Musk xylol (2904.20.30.00) due to the number and position of nitro and methyl groups. Furthermore, it is distinct from the general "Nitrated benzene, nitrated toluene (except p-nitrotoluene), or nitrated naphthalene" (2904.20.35.00) by its specific structural arrangement of nitro and methyl substituents on a xylene base.

As this is a leaf node within the HTS database, there are no further subcategories. Classification under 2904.20.15.00 is therefore specific to p-Nitro-o-xylene, requiring precise identification of the chemical structure to ensure correct tariff treatment.
