9902.06.36 - O-(2-Diethylamino-6-methylpyrimidin-4-yl) O,O-dimethyl phosphorothioate (Pirimiphos-methyl) (CAS No. 29232-93-7) (provided for in subheading 2933.59.18)

This HTS classification, 9902.06.36, specifically addresses the importation of O-(2-Diethylamino-6-methylpyrimidin-4-yl) O,O-dimethyl phosphorothioate, commonly known as Pirimiphos-methyl, with CAS Number 29232-93-7. This compound is a phosphorothioate insecticide and acaricide. Its inclusion within Chapter 99 signifies that it is subject to temporary legislation, trade agreement modifications, or additional import restrictions imposed under Section 22 of the Agricultural Adjustment Act. The reference to subheading 2933.59.18 indicates its primary classification within the chemical compounds chapter before being subjected to these special provisions.

As a specific chemical compound classified under a temporary provision, this node does not have direct "sibling" categories at the same level that are functionally equivalent. The vast number of sibling categories at the HTS database root level, such as live animals (0101-0105), represent entirely different classes of goods with distinct tariff treatments. This category's uniqueness lies in its dual classification: first as a specific chemical (likely falling under Chapter 29 for organic chemicals) and then being pulled into Chapter 99 for special import control or tariff measures.

Since this HTS code is a leaf node, there are no further subcategories. Its classification is definitive and does not break down into more granular product types. Therefore, the focus for importers and customs professionals remains on understanding the precise chemical identity of Pirimiphos-methyl and ensuring compliance with all associated temporary import restrictions and requirements mandated by its inclusion in Chapter 99.
