9902.10.92 - Ethene, 1,1,2,2-tetrafluoro-, oxidized, polymerized, reduced, methyl esters, reduced, 2,3-dihydroxypropyl ethers (CAS No. 925918-64-5) (provided for in subheading 3904.69.50)

This HTS classification, 9902.10.92, pertains to a highly specific chemical compound: ethene, 1,1,2,2-tetrafluoro-, oxidized, polymerized, reduced, methyl esters, reduced, 2,3-dihydroxypropyl ethers. Its inclusion within Chapter 99 signifies it is subject to temporary legislation, trade agreement modifications, or additional import restrictions under Section 22 of the Agricultural Adjustment Act. This provision indicates that while the base chemical structure might find a permanent home in other chapters, its current import status is governed by special, often time-limited, trade policies.

Distinguishing this entry from its sibling categories within Chapter 99 is its unique chemical identity and its specific designation as a "provided for" item under subheading 3904.69.50. This cross-referencing means that the primary classification of this material, absent the temporary measures, would likely be within the polymers of vinyl chloride or other halogenated vinyl polymers. However, its presence in Chapter 99 overrides that and subjects it to the specific rules and potential restrictions outlined in this temporary provision, rather than its general commodity classification.

As this is a leaf node, there are no further subcategories within HTS 9902.10.92. The classification terminates here, emphasizing the specificity of the product and its controlled import status. Any importer must refer to the accompanying notes and proclamations associated with this HTS code to understand the precise conditions and requirements for its entry into the country, as these are dictated by the temporary legislative framework rather than general tariff principles.
