9902.09.28 - Mixtures of 3-dodecyl-1,4-dioxo-1,4-dihydronaphthalen-2-yl acetate (CAS 57960-19-7) (Acequinocyl) and application adjuvants (provided for in subheading 3808.91.25)

This HTS category, 9902.09.28, specifically covers mixtures containing Acequinocyl (CAS 57960-19-7) alongside application adjuvants. Acequinocyl is an acaricide, meaning it is used to control mites. The inclusion of "application adjuvants" indicates that these mixtures are formulated for direct use in agricultural or horticultural applications, enhancing the efficacy or performance of the active ingredient. These products are typically intended for crop protection or pest management.

Distinguishing this category from its siblings is crucial for accurate classification. While other HTS categories might cover the active ingredient Acequinocyl as a single chemical substance (likely under Chapter 29 or 38), or the application adjuvants separately, 9902.09.28 is exclusively for the formulated mixture. This specific subheading is part of Chapter 99, which pertains to temporary legislation and trade agreement modifications, signifying special import considerations beyond standard product classifications. Its placement within Section XXII further emphasizes its unique status.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, classification under 9902.09.28 depends entirely on the presence of both Acequinocyl and application adjuvants within the imported product. Importers should verify the composition of their goods to ensure they precisely match the description, as the mixture of these components is the defining characteristic for this particular classification.
