2926.90.21.00 - Fungicides 🖩

This HTS category, 2926.90.21.00, specifically covers aromatic nitrile-function compounds that function as fungicides. These are organic chemicals containing a nitrile group attached to an aromatic ring structure, and their primary application is in preventing or destroying fungal growth on plants, agricultural produce, or other materials. The classification hinges on the chemical structure (nitrile group on an aromatic ring) and the intended use as a fungicide.

Within the broader context of "Other" aromatic nitrile-function compounds classified under 2926.90, this specific subheading is distinguished from its sibling category, 2926.90.30.00 ("Other"), by its explicit designation as a fungicide. While the sibling category encompasses other aromatic nitrile-function compounds not specifically enumerated as pesticides, this subheading is reserved for those whose fungicidal properties are their defining characteristic for trade purposes.

As a leaf node within the HTS structure, 2926.90.21.00 has no further subcategories. This signifies that all aromatic nitrile-function compounds primarily used as fungicides are consolidated under this single heading. Therefore, classification under this code relies on confirming both the chemical composition (aromatic nitrile) and the declared fungicidal purpose, with no further subdivisions required for this specific product type.
