2904.99.04.00 - o-Nitrochlorobenzene; andp-Nitrochlorobenzene

This HTS category, 2904.99.04.00, specifically covers ortho-nitrochlorobenzene and para-nitrochlorobenzene. These are halogenated derivatives of hydrocarbons that have undergone nitration. They are distinct organic compounds characterized by the presence of both a chlorine atom and a nitro group on a benzene ring, with the specific arrangement of these substituents defining whether the compound is ortho (adjacent) or para (opposite) substituted.

Within the broader classification of sulfonated, nitrated, or nitrosated hydrocarbon derivatives, this subcategory distinguishes itself from its sibling, 2904.99.08.00, which encompasses "Other" derivatives that do not fit the specific definitions of monochloromononitrobenzenes or other listed exclusions. The focus here is on the precise structural isomers of monochloromononitrobenzene.

As a leaf node in the HTS, there are no further subdivisions under this code. Classification decisions within this category will therefore rely on the definitive chemical identification of the imported or exported substance as either ortho-nitrochlorobenzene or para-nitrochlorobenzene, based on analytical evidence and established chemical nomenclature.
