9902.09.20 - Product mixtures containing 4-{[(6-chloro-3-pyridinyl)methyl](2,2-difluoroethyl)amino}-2(5H)-furanone (Flupyradifurone) (CAS No. 951659-40-8) (provided for in subheading 3808.91.25)

This HTS category, 9902.09.20, specifically covers product mixtures containing the insecticide Flupyradifurone (CAS No. 951659-40-8). These mixtures are subject to temporary modifications and additional import restrictions, as indicated by their placement within Chapter 99 of the Harmonized Tariff Schedule. The inclusion of "provided for in subheading 3808.91.25" within the description signifies that these are treated as insecticides under that principal HTS heading, but are further regulated or modified by this specific Chapter 99 provision.

Distinguishing this category from its sibling entries at the same level, which largely consist of live animals and other general commodities, is straightforward. The unique nature of 9902.09.20 lies in its specific chemical composition and its application as an agricultural chemical, coupled with the temporary legislative provisions governing its importation. Unlike broad categories like "Live bovine animals" or "Live poultry," this entry addresses a highly specialized product with specific regulatory oversight.

As a leaf node within the HTS database, category 9902.09.20 does not have further subcategories. Therefore, classification under this heading requires a direct determination that the imported product meets the specific chemical description and falls under the stipulated temporary legislative framework. The primary classification criteria revolve around the presence of Flupyradifurone and the applicable temporary duty rates or import restrictions associated with this special provision.
