9902.10.94 - Methoxycarbonyl-terminated perfluorinated polyoxymethylene-polyoxyethylene (CAS No. 107852-49-3) (provided for in subheading 3904.69.50)

This HTS category, 9902.10.94, specifically covers methoxycarbonyl-terminated perfluorinated polyoxymethylene-polyoxyethylene with CAS number 107852-49-3. These are specialized fluoropolymers that are further classified under subheading 3904.69.50, indicating their nature as fluorinated derivatives of poly(vinyl chloride) or other halogenated olefins. The inclusion of this specific HTS code within Chapter 99 signifies that these goods are subject to temporary legislation, temporary modifications, or additional import restrictions, often related to trade agreements or agricultural adjustments.

Distinguishing this category from its siblings at the root level is straightforward. The HTS root (Chapter 99) is dedicated to temporary legislative measures and special provisions, not to the classification of general merchandise like live animals (Chapters 01), edible products (Chapters 02-24), or even most manufactured goods (Chapters 25-97). Therefore, 9902.10.94 is unique in its focus on specific temporary trade measures for a particular chemical compound, while its siblings represent the broad spectrum of goods that fall under the general HTS classification system.

As a leaf node, this classification does not have any subcategories. Its specific nature as a methoxycarbonyl-terminated perfluorinated polyoxymethylene-polyoxyethylene means that further subdivision within this particular HTS code is not required. The existing description and CAS number provide the precise identification for classification purposes under the temporary provisions of Chapter 99.
