2926.90.23.00 - 3,5-Dibromo-4-hydroxybenzonitrile (Bromoxynil)

This classification, 2926.90.23.00, specifically covers the aromatic nitrile-function compound 3,5-Dibromo-4-hydroxybenzonitrile, commonly known as Bromoxynil. As a herbicide, its primary function is the control of broadleaf weeds in various agricultural applications. This classification is part of the broader category of "Other" aromatic nitrile-function compounds, distinguishing it from any specifically enumerated types within this sub-heading.

Within the "Pesticides" and subsequently "Herbicides" categories of aromatic nitrile-function compounds, this particular HTS code is distinct from its sibling, 2926.90.25.00, which is designated for "Other" herbicides of this type. The crucial distinction lies in the specific chemical identity of Bromoxynil, which is explicitly listed under this code. Since this is a leaf node, there are no further subcategories; therefore, classification under this code relies on the precise chemical identification and intended pesticidal use of the imported or exported product.
