Wood, windows, French-windows and their frames, (of other than tropical wood).
Classification of wood window frames under HS 4418.19
Wood window frames are classified under HS code 4418.19. Heading 4418 covers builders' joinery and carpentry of wood, which includes products used in the construction of buildings. Subheading 4418.11 is reserved for products made from specific tropical woods listed in the Chapter 44 Subheading Notes. Therefore, window frames made from temperate woods like pine, oak, or maple fall under 4418.19. This classification includes the frame itself, the sash, and French-windows. The classification is based on the fact that these are finished or semi-finished components of a building's structure. It does not include the glass if shipped separately; however, if the window is imported as a complete unit with glass installed, it is still generally classified under 4418.19 as the wood frame gives the product its essential character for builders' joinery. The frames may be painted, stained, or otherwise treated, and may include metal hardware like hinges or latches already attached.

Codes often confused with 4418.19
Common mistake. The most common misclassification is 4418.11, which is specifically for window frames made of tropical wood. Importers must verify the wood species to ensure they are not using the tropical wood code for temperate wood products. Another error is using 4418.20, which is the code for wooden doors and their frames. While windows and doors are similar, they are distinct subheadings. Additionally, if the frames are imported as simple lengths of wood that have not been joined into a frame, they might be misclassified as wood moldings under 4409, rather than builders' joinery under 4418.

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).
