9902.09.26 - Product mixtures containing (Z)-2-chloro-1-(2,4,5-trichlorophenyl)vinyl dimethylphosphate (Tetrachlorvinfos) (CAS No. 22248-79-9) (provided for in subheading 3808.91.25)

This HTS category, 9902.09.26, specifically addresses product mixtures containing the insecticide (Z)-2-chloro-1-(2,4,5-trichlorophenyl)vinyl dimethylphosphate, also known as Tetrachlorvinfos. These mixtures are designated for temporary importation or modification under specific trade agreements or import restrictions, as outlined by Chapter 99 of the HTSUS. While the core chemical compound might be regulated under other HTS headings, this particular classification is reserved for its presence within formulated products, indicating a special customs treatment.

Distinguishing this category from its sibling entries, which predominantly cover live animals, is straightforward. Unlike the broader chapters that deal with basic agricultural products or raw materials, 9902.09.26 pertains to a highly specific chemical formulation with a designated purpose as an insecticide. Its presence within Section XXII signifies its exceptional nature, differing from standard import classifications that would otherwise apply to pesticides, which are typically found in Chapter 38.

As a leaf node, this classification does not have further subcategories. Its specificity ensures that any import or transit of product mixtures containing Tetrachlorvinfos under these temporary provisions are precisely identified and subject to the stipulated regulations, ensuring compliance with specialized trade policies and restrictions.
