9902.10.91 - 1-Propene, 1,1,2,3,3,3-hexafluoro-, oxidized, polymerized, reduced, hydrolyzed (CAS No. 161075-14-5) (provided for in subheading 3904.69.50)

This classification pertains to a specific, chemically modified fluorinated propene derivative. The material, identified by CAS No. 161075-14-5, has undergone a series of processes including oxidation, polymerization, reduction, and hydrolysis. Its primary characteristic is its complex chemical structure resulting from these transformations of 1-propene. It is important to note that while the description lists several chemical modifications, the controlling factor for this classification is the final state of the polymerized and hydrolyzed product derived from hexafluoropropene.

As this is a leaf node within Chapter 99 of the HTS, it represents a highly specific entry. Its siblings are found within the broader categories of Chapter 99, which typically cover temporary legislation, trade agreement modifications, and specific import restrictions. Unlike more general entries within Chapter 99 that might address broad categories of goods subject to temporary measures, this node is reserved for the uniquely defined chemical product. Its existence at this level signifies a particular import scenario or restriction related to this specialized material.

Given that this is a leaf node, there are no further subcategories. The classification is definitive for the described material. Its inclusion under Section XXII signifies that its classification is governed by special provisions, temporary legislation, or specific trade agreement actions, overriding or supplementing the standard classifications found in other sections of the HTS. The reference to subheading 3904.69.50 indicates that this material, under different circumstances or without the special provisions of Chapter 99, would likely be classified within the broader category of fluoropolymers.
