2924.21.16.00 - Other

This classification, HTS 2924.21.16.00, is designated for "Other" aromatic ureines and their derivatives, and salts thereof, that are pesticides. It serves as a residual category for aromatic ureine-based pesticides that do not specifically fall under the more precisely defined sibling categories within this HTS subgroup. These compounds are characterized by their chemical structure, featuring an aromatic ring system linked to a urea functional group, and are primarily utilized for their pest control properties.

The distinction of this category from its siblings lies in its broad application. While sibling categories like 2924.21.04.00 (Monuron) and 2924.21.08.00 (Fluometuron) specifically name and describe certain prominent pesticidal ureines, HTS 2924.21.16.00 captures any other aromatic ureine-based pesticides that possess the defining structural and functional characteristics but are not individually enumerated. This ensures comprehensive coverage of related chemical substances used for similar agricultural or pest management purposes.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within this specific code is determined by meeting the criteria of being an aromatic ureine derivative with pesticidal application, while not matching the precise chemical identity of the more specifically listed sibling items. Therefore, meticulous examination of chemical nomenclature and intended use is paramount for accurate classification.
