9902.10.83 - 1,1,2-Trifluoroethene - 1,1-difluoroethene (1:1) (Vinylidene fluoride-trifluoroethylene copolymer) (CAS No. 28960-88-5) (provided for in subheading 3904.69.50)

HTS Code 9902.10.83 specifically covers a designated copolymer, identified as 1,1,2-trifluoroethene - 1,1-difluoroethene (1:1), also known as vinylidene fluoride-trifluoroethylene copolymer (CAS No. 28960-88-5). This classification falls under Chapter 99, which is reserved for temporary legislation, trade agreement modifications, and specific import restrictions, notably those proclaimed under Section 22 of the Agricultural Adjustment Act. The "provided for" notation indicates that while this material has a primary classification under a permanent HTS chapter (3904.69.50, which generally covers fluoropolymers), it is subject to the temporary provisions outlined in Chapter 99.

This specific classification is distinct from the broader categories found elsewhere in the HTS, such as the primary chapters dealing with plastics (Chapter 39). While the material's chemical composition and use would place it within a permanent classification, the 9902 code signifies a temporary trade policy measure, potentially a quota, tariff rate quota, or other restriction, that is not reflected in the permanent structure. It does not directly compare to sibling categories within Chapter 99 without further context, as Chapter 99 itself is a collection of diverse temporary measures.

As a leaf node, HTS Code 9902.10.83 does not possess subcategories. The classification represents a precise designation for a particular chemical compound under a temporary trade provision. Therefore, understanding this classification requires focusing on the specific substance and the nature of the temporary measure it falls under, as indicated by its inclusion in Chapter 99 and its "provided for" reference to a permanent HTS classification.
