Classification of PVC windows under HS 3925.20
PVC windows and their frames are classified under HS code 3925.20. This code falls within the broader category of builders' ware of plastics. The Harmonized System specifically designates this subheading for doors, windows, and their frames and thresholds for doors. To be classified here, the window must be primarily constructed from plastic, typically unplasticized PVC (uPVC) or rigid PVC. This includes the frame, the sash, and any integrated plastic components. Even if the window includes glass panes (glazing) and metal hardware such as hinges, locks, and handles, the \"essential character\" of the product as a \"plastic window\" usually dictates classification under 3925.20, provided the plastic frame is the defining structural element. This classification is used globally by customs authorities to monitor the trade of construction materials and ensures that finished window units are distinguished from the raw profiles used to manufacture them. According to the Explanatory Notes to heading 3925, these articles are intended for permanent installation in buildings. Therefore, a complete window unit, whether glazed or unglazed, is correctly placed here.

Codes often confused with 3925.20
Common mistake. A frequent misclassification occurs with HS code 3916.20, which is for PVC profiles. Profiles are the raw, continuous lengths of plastic used to make the frames. Once those profiles are cut and joined to form a window frame, they must be moved to 3925.20. Another error involves HS code 7013, which covers glassware; however, a window is a composite article where the frame (plastic) generally determines the classification over the glass.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
