9902.10.80 - Poly(1,1,2,2-tetrafluoro-2-[(trifluoroethenyl)oxy]ethanesulfonyl fluoride-co-tetrafluoroethylene) SO2F form (CAS No. 69462-70-0) (provided for in subheading 3904.69.50)

This HTS category, 9902.10.80, specifically covers Poly(1,1,2,2-tetrafluoro-2-[(trifluoroethenyl)oxy]ethanesulfonyl fluoride-co-tetrafluoroethylene) in its SO2F form, identified by CAS Number 69462-70-0. While classified under Section XXII, which pertains to temporary legislation and special provisions, the underlying material is provided for in subheading 3904.69.50, indicating its nature as a fluoropolymer. This classification is reserved for specific temporary trade measures or restrictions impacting this particular polymer.

Distinguishing this category from its sibling categories at the Chapter 99 level is crucial. Chapter 99 is generally reserved for temporary legislation, trade agreement modifications, and Section 22 restrictions related to agricultural goods. Unlike the primary HTS chapters that classify goods based on their inherent nature (e.g., live animals, textiles, machinery), Chapter 99 serves as a dynamic layer that can alter or supplement the classification and duty treatment of goods under specific, often time-limited, circumstances. Therefore, 9902.10.80 is not distinguished by the inherent properties of the polymer itself, but rather by the temporary legislative or trade policy context under which it is being classified.

As this is a leaf node, there are no subcategories. The classification ends at this specific HTS code, meaning that further breakdowns within this entry are not defined. Any imported product meeting the description of Poly(1,1,2,2-tetrafluoro-2-[(trifluoroethenyl)oxy]ethanesulfonyl fluoride-co-tetrafluoroethylene) SO2F form (CAS No. 69462-70-0) and subject to the specific temporary provisions of Chapter 99 will be classified here, without further subdivisions. The primary classification criteria are the chemical identity of the polymer and its entry under a temporary HTS measure.
