Last updated: August 2026 dataPlastic doors and door frames (3925200010), windows and window frames (3925200020), and door thresholds (3925200091) are builders' articles that serve as direct substitutes for wood or aluminum equivalents in residential and commercial construction. PVC is the dominant polymer in this category, and products are often evaluated against ASTM or local building-code performance standards before specification. Imports from certain origins are subject to Section 301 tariffs, making origin documentation and first-sale valuation strategies particularly relevant for large construction-project procurement.

Classification of composite articles follows the component that gives the product its essential character. A plastic-framed window with glass panes is generally classified under 3925.20 based on the plastic frame providing the structural identity, but CBP may examine the relative value and function of each material. A binding ruling is advisable for high-volume shipments of combination units.
A door threshold is a finished builders' article specifically shaped and designed for installation at the base of a door opening. Generic plastic profiles or extruded strips not cut or finished for that specific end use are typically classified under Chapter 39 profile headings rather than as builders' ware.
