Overview

This HTS classification, 9902.09.32, specifically addresses formulations containing zinc phosphide (trizinc diphosphide), identified by CAS Number 1314-84-7. These substances are primarily used as rodenticides and are placed under this temporary provision for purposes of import restrictions or special tariff treatments as defined by the context of Chapter 99. It is crucial to note that the underlying commodity classification for zinc phosphide formulations falls within subheading 3808.91.30 of the standard HTS.

Distinguishing this category from its sibling categories within Chapter 99 is paramount. While Chapter 99 as a whole deals with temporary legislation, trade agreement modifications, and special import restrictions, the individual subheadings within it delineate specific types of such provisions. This particular subheading focuses exclusively on chemical formulations for pest control, namely those containing zinc phosphide, and would differ from other 9902 subheadings that might address different types of temporary measures or restricted goods.

As HTS code 9902.09.32 is a leaf node, it does not possess subcategories. Therefore, the classification is definitive for goods meeting the description. Importers and exporters should confirm that their product is indeed a formulation containing zinc phosphide and that it falls under the purview of the specific temporary legislation or restriction indicated by its placement in Chapter 99. Classification relies on the chemical composition and intended use as a pest control agent.
