Overview
This HTS code, 9902.10.85, covers highly specialized chemical mixtures designated for temporary modification or restriction under specific trade legislation. The primary components are complex polymers derived from propanoic acid and a specific isocyanato-trimethylcyclohexane, alongside reduced methyl esters of oxidized tetrafluoroethylene compounds. The mixture also contains trace amounts of isopropanol and butanone, with water as the predominant remaining content. This classification is specifically tied to the provisions within Chapter 99 of the HTS, which deals with temporary legislation and import restrictions, often related to agricultural policy as outlined in Section 22 of the Agricultural Adjustment Act.
Unlike the broad commodity classifications found in earlier chapters of the HTS, such as live animals (Chapters 01) or basic chemicals, this entry is highly specific. Its scope is not defined by a general product type but by a precise chemical composition and its regulatory status. The inclusion of CAS numbers and specific percentage ranges for constituent chemicals highlights its unique nature and the detailed analytical requirements for its proper classification.
As this is a leaf node within the HTS database, there are no further subcategories to explore. The classification is complete at this level, meaning that any product meeting the precise description provided by this HTS code will be treated under these specific temporary provisions. Its distinction from other entries, even within Chapter 99, rests on the exact chemical makeup and the particular trade agreement or legislative action that necessitates its separate classification and potential import limitations.
