9902.09.91 - Mixtures of ethyl 2-chloro-5-(4-chloro-5-difluoromethoxy-1-methyl-1H-pyrazol-3-yl) -4-fluorophenoxyacetate (Pyraflufen-ethyl) (CAS No. 129630-19-9) and application adjuvants (provided for in subheading 3808.93.15)

This HTS category, 9902.09.91, specifically covers mixtures that contain Pyraflufen-ethyl (CAS No. 129630-19-9), an active ingredient used in agricultural pesticides, along with application adjuvants. These adjuvants are themselves classified under subheading 3808.93.15, indicating their role in enhancing the effectiveness or application of the pesticide. The inclusion of "provided for in subheading 3808.93.15" is crucial for classification, as it links this temporary provision to the established classification of such chemical mixtures.

Distinguishing this category from its siblings within Chapter 99 is straightforward. Chapter 99 is dedicated to temporary legislation and modifications to the HTS. Therefore, all entries within Chapter 99, including 9902.09.91, are inherently temporary and relate to specific legislative actions or trade agreements, unlike the permanent classifications in earlier chapters (e.g., Chapter 01 for live animals). This specific code is for a particular chemical mixture with a designated use and composition, differentiated from other temporary measures that might address different goods or import conditions.

As HTS code 9902.09.91 is a leaf node, it does not have subcategories. This means that once a product meets the criteria for classification under this specific code, its classification is complete at this level. The description itself provides the necessary detail to identify the precise product, which is a mixture of Pyraflufen-ethyl and specific application adjuvants. The classification relies on identifying both components and their intended use as a pesticide formulation.
