9902.03.35 - (Z)-2-Chloro-1-(2,4,5-trichlorophenyl)vinyl dimethyl phosphate (Tetrachlorvinfos) (CAS No. 22248-79-9) (provided for in subheading 2919.90.30)

This HTS category, 9902.03.35, covers the specific organophosphate insecticide known as (Z)-2-Chloro-1-(2,4,5-trichlorophenyl)vinyl dimethyl phosphate, also referred to as Tetrachlorvinfos, with CAS Number 22248-79-9. Its inclusion within Chapter 99 signifies a temporary legislative measure or a specific temporary modification to import regulations, often related to agricultural import restrictions under Section 22 of the Agricultural Adjustment Act. This classification is distinct from the primary chemical classifications found in Chapters 28 and 29, which would typically classify such compounds based on their chemical structure and composition without these specific import control provisions.

As a leaf node, this category does not have further subcategories. Its specificity underscores that the intention of this tariff provision is to regulate the import of Tetrachlorvinfos under particular circumstances or for specific purposes outlined by the temporary legislation. Importers will find that the duty rate and any accompanying import restrictions for this substance are determined by this specialized 99-series code, overriding the general classification it might otherwise fall under, such as subheading 2919.90.30. The sole purpose of this classification is to manage the entry of this particular pesticide according to the temporary proclamations that govern its import.
