2926.90.25.00 - Other

This HTS category, 2926.90.25.00, encompasses "Other" nitrile-function compounds that are not specifically enumerated elsewhere within the broader categories of aromatic nitrile-function compounds used as pesticides. It serves as a residual classification for those substances that meet the general criteria of having a nitrile group attached to an aromatic ring system and are primarily intended for use in agricultural pest control, but do not fit into more specific sub-classifications.

The key differentiator for this category is its residual nature. For instance, while its sibling category 2926.90.23.00 specifically identifies 3,5-Dibromo-4-hydroxybenzonitrile (Bromoxynil), this category captures any other aromatic nitrile herbicides that do not have a dedicated HTS code. Classification here requires a careful examination of the chemical structure and intended application to confirm it is indeed an aromatic nitrile herbicide and not classifiable under other chapters or more specific headings for organic chemicals.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, the focus for classification purposes under 2926.90.25.00 lies in the precise chemical identity and primary use of the product. Importers and exporters must demonstrate that the good is an aromatic nitrile compound, is intended for use as a herbicide, and does not fall under any more precisely defined HTS classification.
