3925.20.00.20 - Windows and window frames

This HTS category, 3925.20.00.20, specifically covers windows and their frames when manufactured from plastics. This includes a wide range of window assemblies, such as casement windows, sliding windows, awning windows, and fixed windows, provided their primary construction material is plastic. The category encompasses both the window pane itself (if integrated with the frame as a unit) and the surrounding plastic frame structure designed for installation into buildings.

It is important to distinguish this category from its sibling, 3925.20.00.10, which classifies doors and door frames made of plastics. While both relate to building components, this category is exclusively for windows and their associated frames, whereas the sibling category pertains to ingress and egress doors. Additionally, any other plastic builders' ware not specifically covered by other headings or subheadings would fall under a more general "other" category.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the classification of a product under 3925.20.00.20 depends on its primary function as a window assembly, its composition being predominantly plastic, and its intended use as a building component.
