9902.09.31 - Mixtures of (E)-N1-[(6-chloro-3-pyridyl)methyl]-N2-cyano-N1-methyl-acetamidine (Acetamiprid) (CAS No. 135410-20-7) and application adjuvants (provided for in subheading 3808.91.25)

This HTS category, 9902.09.31, covers specific mixtures containing the insecticide Acetamiprid (CAS No. 135410-20-7) and application adjuvants. These mixtures are primarily intended for agricultural use, with the Acetamiprid acting as the active pesticidal ingredient and the adjuvants enhancing its application and effectiveness. The inclusion of "application adjuvants" signifies that these are not simply pure Acetamiprid but formulated products designed for practical use.

While other HTS codes within Chapter 38 may cover general pesticides or chemical mixtures, this specific classification under Chapter 99 signifies a temporary legislative provision. This means these goods are subject to special tariff treatment or import restrictions, often related to trade agreements or specific agricultural policies. Therefore, this category is distinct from broad classifications of pesticides in Chapter 38 because of its temporary and conditional nature.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within 9902.09.31 is definitive based on the product meeting the criteria of being a mixture of Acetamiprid and application adjuvants, and being subject to the temporary provisions outlined in Chapter 99. Importers must ensure their goods precisely match this description and any associated temporary legislation to correctly apply this classification.
