2904.20.45.00 - Other

This HTS subheading, 2904.20.45.00, covers "Other" aromatic sulfonated, nitrated, or nitrosated hydrocarbon derivatives that contain only nitro or only nitroso groups. It acts as a residual category for aromatic compounds fitting the broader description within Chapter 29, specifically those with nitro or nitroso functional groups, but which do not fall under more specific classifications within this family of chemicals. These are generally organic compounds derived from hydrocarbons where an aromatic ring structure is present, and it has undergone sulfonation, nitration, or nitrosation, with the exclusion of halogenated derivatives or those with other functional groups.

This category is distinguished from its sibling, 2904.20.40.00, which specifically covers products described in additional U.S. note 3 to section VI. Therefore, 2904.20.45.00 is intended for those aromatic nitro or nitroso derivatives that do *not* meet the criteria outlined in that specific additional U.S. note. Classification hinges on precise chemical structure and adherence to the specific conditions set forth in the HTSUS.

As this is a leaf node in the HTS classification system, there are no further subcategories. The scope of 2904.20.45.00 is therefore final at this level, encompassing all remaining aromatic sulfonated, nitrated, or nitrosated hydrocarbon derivatives containing only nitro or nitroso groups that have not been specifically enumerated in preceding or sibling HTS subheadings. Examples might include certain aromatic nitro-compounds used as intermediates in the synthesis of dyes, pharmaceuticals, or other fine chemicals, where their specific chemical structure and absence of other specified functional groups or qualifying notes place them within this residual classification.
