9902.09.19 - Product mixtures containing (RS)-α-cyano-4-fluoro-3-phenoxybenzyl (1RS, 3RS; 1RS, 3SR)- 3 - (2,2-dichlorovinyl) - 2, 2-dimethylcyclopropanecarboxylate (β-Cyfluthrin) (CAS No. 68359-37-5) (provided for in subheading 3808.91.25)

This HTS category, 9902.09.19, covers specific product mixtures containing the active insecticide ingredient known as β-Cyfluthrin. The CAS number 68359-37-5 is provided for precise identification of this chemical compound. Importantly, these mixtures are also classified under subheading 3808.91.25, indicating their intended use as insecticides, which are themselves preparations for the retail sale of combating pests. This specific classification within Chapter 99 signifies a temporary modification or special provision related to the importation of this particular β-Cyfluthrin mixture.

Distinguishing this category from its siblings, which span a wide array of live animals from horses to poultry, is straightforward. While the sibling categories at this level are dedicated to the import of live animals, HTS 9902.09.19 is entirely focused on a specific chemical product, an insecticide preparation. The core difference lies in the nature of the goods: living creatures versus a formulated chemical substance for pest control. This temporary provision exists independently of the broad classifications for agricultural and animal products found in earlier chapters.

As this is a leaf node within the HTS structure, there are no further subcategories branching from 9902.09.19. Its specific nature as a temporary provision means it addresses a singular, precisely defined product. Therefore, the classification is exact, and no further subdivisions are needed to delineate different types or forms of goods under this particular code. The focus remains on the unique characteristics and regulated status of the β-Cyfluthrin product mixture.
