4418.21.40.00 - French doors

This HTS classification, 4418.21.40.00, specifically covers French doors constructed from tropical wood. French doors are characterized by their dual-panel design, often featuring glass panes within the door panels, designed to open outwards or inwards, typically in pairs. This category falls under builders' joinery and carpentry of wood, signifying their primary use in the construction of buildings. The "tropical wood" designation is crucial, indicating that the primary material composition of these doors originates from specific timber-producing regions.

The primary distinction for this category lies in its specificity of "French doors" within the broader "Doors and their frames and thresholds" grouping. Unlike its sibling category, 4418.21.80, which is designated for "Other" doors of tropical wood, this entry is exclusively for the French door style. This means that while other types of tropical wood doors, such as single-panel doors, sliding doors, or bifold doors made of tropical wood, would fall under the "Other" sibling, French doors are explicitly captured here.

As this classification represents a leaf node, there are no further subcategories for French doors of tropical wood. Therefore, the focus for classification purposes at this level remains on the material (tropical wood) and the specific design and function of the item as French doors, aligning with the established definitions within Chapter 44.
