Overview

This HTS classification covers a specific chemical compound, [3-(4,5-Dihydro-1,2-oxazol-3-yl)-4-mesyl-o-tolyl](5-hydroxy-1-methylpyrazol-4-yl)methanone, identified by CAS No. 210631-68-8 and commonly known as Topramezone. Its inclusion under Chapter 99 signifies that it is subject to temporary legislation, trade agreement modifications, or additional import restrictions. Specifically, Topramezone is provided for under subheading 2934.99.15, indicating it is a heterocyclic compound.

As a leaf node, this category does not have further subdivisions within the HTS. Its classification is highly specific to the chemical structure and identity of Topramezone. Distinguishing it from sibling categories, which broadly cover live animals and various chapters of manufactured goods and raw materials, is straightforward due to Topramezone's nature as a precisely defined chemical substance. Its function as a herbicide is relevant to its intended use, but classification under Chapter 99 supersedes general use-based provisions.

The primary classification criteria for this node are the precise chemical name, CAS Registry Number, and the reference to its provision under subheading 2934.99.15. Importers must ensure that all documentation accurately reflects this identity. Given the nature of Chapter 99 provisions, specific adherence to the terms and conditions outlined in the relevant trade agreements or temporary legislation is paramount for correct importation.
