Mountings, fittings and similar articles, of base metal, suitable for buildings.
Classification of window fittings under HS 8302.41
Window fittings made of base metal are classified under HS code 8302.41. Heading 8302 covers a broad range of base metal mountings, fittings, and similar articles suitable for furniture, doors, staircases, windows, and buildings. According to the General Interpretative Rules, classification is determined by the material (base metal) and the application (suitable for buildings). Subheading 8302.41 is specifically provided for articles suitable for buildings, which distinguishes them from fittings for furniture (8302.42) or coachwork (8302.30). These items are designed to be permanently attached to window frames or sashes to enable movement, locking, or structural support. The term "base metal" includes iron, steel, aluminum, copper, and various alloys. If the fitting is a complex mechanical device like a motorized window opener, it may move to Chapter 84, but standard manual hardware remains in 8302.

Codes often confused with 8302.41
Common mistake. A common misclassification occurs with HS code 3925, which covers plastic builders' ware. If the window fittings are made of plastic rather than metal, they must be classified in Chapter 39. Another error is using 7318 for screws or bolts used to install the windows; while these are hardware, 7318 is for general-purpose fasteners, whereas 8302.41 is for specialized fittings. Furthermore, automatic door or window closers are classified under 8302.60, which is a specific subheading that takes precedence over the general building fittings code.

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).
