7610.10.00.10 - Windows and their frames

This HTS category, 7610.10.00.10, specifically classifies windows and their frames constructed from aluminum. This heading encompasses complete window units, ready for installation, including the glazing elements if they are an integral part of the assembly, as well as the separate aluminum frames designed for such windows. The primary material characteristic is aluminum, and the function is to provide an opening in a building or structure that can be closed or opened, typically for light and ventilation.

It is crucial to distinguish this classification from its sibling categories. While 7610.10.00.20 covers thresholds for doors, this heading focuses exclusively on the window components. Thresholds are distinct functional elements at the base of door openings, whereas windows are designed for openings in walls or roofs. The "Other" category (7610.10.00.30) serves as a residual classification for any aluminum structures or parts thereof covered by the parent heading 7610 that do not fall under the more specific subheadings for windows, doors, thresholds, or other enumerated items.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification within 7610.10.00.10 relies on the precise definition of "windows and their frames" made of aluminum. This includes various types of windows such as casement, sliding, awning, and fixed windows, provided they are constructed predominantly from aluminum and are intended for building structures.
