2904.20.40.00 - Products described in additional U.S. note 3 to section VI 🖩

This HTS classification, 2904.20.40.00, encompasses aromatic hydrocarbon derivatives that contain only nitro or nitroso groups, and do not fall under the more specific classifications within this chapter. These compounds are characterized by the presence of one or more nitro (-NO2) or nitroso (-NO) groups attached to an aromatic ring structure. The key distinguishing factor for this category is the absence of any halogens or sulfonyl/sulfonamide groups; if such additional functional groups were present, they would be classified elsewhere.

Within the broader category of "Aromatic: Other," this specific code is further distinguished from its sibling, 2904.20.45.00, which also represents "Other" aromatic derivatives containing only nitro or nitroso groups. The practical difference typically lies in the specific additional U.S. note mentioned in the description, which may provide detailed criteria or list specific compounds that fall under 2904.20.40.00, thereby delineating its precise scope from other "other" classifications.

As a leaf node, 2904.20.40.00 does not have further subcategories. Therefore, classification at this level relies heavily on a thorough understanding of the chemical structure and the specific requirements outlined in additional U.S. note 3 to section VI. Importers and exporters should carefully consult this note to ensure accurate classification, as it provides the definitive guidance for determining whether a particular aromatic nitro or nitroso compound fits within this specific tariff code.
