9902.05.16 - O,S-Dimethyl acetylphosphoramidothioate (Acephate) (CAS No. 30560-19-1) (provided for in subheading 2930.90.43)

This HTS classification, 9902.05.16, pertains to O,S-Dimethyl acetylphosphoramidothioate, commonly known as Acephate. Acephate is a specific organophosphate insecticide, identified by its CAS number 30560-19-1. Its inclusion within Chapter 99 signifies that it is subject to temporary legislation, trade agreement modifications, or additional import restrictions, as proclaimed under Section 22 of the Agricultural Adjustment Act, as amended. This provision indicates that while Acephate might otherwise be classified under a standard HTS heading (in this case, referenced as subheading 2930.90.43), its import is subject to specific, potentially fluctuating, regulatory measures.

Distinguishing this category from its siblings is crucial. The sibling categories listed at the HTS Database Root level, such as live animals (0101-0105), represent entirely different classes of goods, primarily based on their biological state and species. HTS Chapter 99, by its nature, is a distinct section reserved for temporary and specialized provisions, often impacting a wide range of commodities that are otherwise classified in Chapters 1 through 98. Therefore, 9902.05.16 stands apart due to its specific purpose as an insecticide and its direct association with trade policy mechanisms rather than fundamental product categories.

As a leaf node, HTS 9902.05.16 does not have further subdivisions. Its classification is definitive for Acephate when imported under the specified temporary legislative conditions. The primary classification criteria for this entry are the precise chemical identity of the substance (O,S-Dimethyl acetylphosphoramidothioate), its common name (Acephate), and its associated CAS number. Importers must also be aware of and comply with any specific proclamations, quotas, or licensing requirements that are currently in effect under Chapter 99 for this particular product.
