Overview

This HTS classification, 9902.05.03, specifically covers the chemical compound 2-[4-(Methylsulfonyl)-2-nitrobenzoyl]-1,3-cyclohexanedione, commonly known as Mesotrione and identified by CAS No. 104206-82-8. This compound is provided for in subheading 2930.90.10 under the general provisions for organic chemicals. Its inclusion within Chapter 99 signifies that it falls under temporary legislation, temporary modifications, or additional import restrictions proclaimed pursuant to trade agreements or Section 22 of the Agricultural Adjustment Act.

As a leaf node within Chapter 99, this specific HTS code does not have further subdivisions. Its distinguishing characteristic lies in its unique chemical identity and the specific regulatory context it occupies under temporary trade measures. Unlike sibling categories at the HTS Database Root level which represent broad product groups like live animals (Chapters 01-05), this classification is highly specific, targeting a single chemical substance subject to particular import provisions.

Therefore, importers and exporters dealing with Mesotrione should note that its classification under 9902.05.03 supersedes its potential classification under the standard chemical headings, indicating that specific temporary rules or restrictions apply. This necessitates careful adherence to the conditions and documentation required for its importation or exportation as stipulated by the relevant trade agreements and agricultural adjustment legislation.
