9902.03.39 - O,O-Diethyl phosphorochloridothioate (CAS No. 2524-04-1) (provided for in subheading 2920.19.50)

This HTS category, 9902.03.39, specifically covers O,O-Diethyl phosphorochloridothioate, identified by CAS No. 2524-04-1. This classification is not based on the inherent nature of the chemical itself, but rather on its temporary treatment under specific trade and agricultural legislation. The parent chapter, 99, deals with temporary measures such as modifications proclaimed pursuant to trade agreements or additional import restrictions under Section 22 of the Agricultural Adjustment Act. Therefore, goods classified here are subject to specific, time-limited regulations.

Unlike sibling categories that broadly classify live animals or other general goods, this entry targets a precise chemical compound. Its inclusion within Chapter 99 signifies a regulatory status rather than a standard commodity classification. The parenthetical reference to subheading 2920.19.50 indicates that, absent these temporary provisions, O,O-Diethyl phosphorochloridothioate would ordinarily fall under a different chapter, specifically Chapter 29, which covers organic chemicals.

As this is a leaf node, there are no further subcategories within 9902.03.39. The classification is definitive for the specified chemical under the prevailing temporary legislation. Importers and exporters should consult the specific proclamations and regulations associated with Chapter 99 to understand the precise import or export conditions, duties, or restrictions applicable to O,O-Diethyl phosphorochloridothioate.
