9902.10.95 - Ethene, tetrafluoro, oxidized, polymerized, reduced, methyl esters, reduced, ethoxylated (CAS No. 162492-15-1) (provided for in subheading 3904.69.50)

This HTS category, 9902.10.95, covers a highly specific chemical substance identified by CAS No. 162492-15-1. The description indicates a product that has undergone a complex series of chemical processes including oxidation, polymerization, reduction, esterification (methyl esters), further reduction, and ethoxylation, all originating from ethene that has been tetrafluorinated. This precise chemical composition and manufacturing pathway are key identifiers for goods falling under this provision.

As a leaf node within Chapter 99, this category does not have further subcategories to subdivide its scope. Its placement within Section XXII and Chapter 99 signifies that it represents a temporary legislative provision, likely a modification proclaimed pursuant to trade agreements or an additional import restriction under Section 22 of the Agricultural Adjustment Act. This temporary nature distinguishes it from permanent classifications found in Chapters 1-97 of the HTS.

Therefore, the classification under 9902.10.95 is entirely dependent on the precise chemical identity and processing history of the imported goods, aligning with the specific temporary trade or agricultural policy it serves. It is crucial for importers to confirm that their product precisely matches the described chemical structure and processing steps to ensure correct classification under this provision, which is explicitly stated as being "provided for in subheading 3904.69.50" under permanent tariff provisions.
