Product classification
HS code for Modular wood house: 9406.10
Buildings, prefabricated, of wood.
Classification of modular wood house under HS 9406.10
Modular wood houses are classified under HS code 9406.10 because they meet the definition of prefabricated buildings as outlined in the Harmonized System. According to the Chapter 94 notes, prefabricated buildings are structures that are finished in the factory or put up as elements, presented together, to be assembled on site. Since wood is the predominant structural material, the specific subheading 9406.10 is applied. This classification covers the entire structure, including floors, walls, and roofs, provided they are imported as a complete unit or a kit intended for assembly. The classification remains valid even if the house is missing minor components like glass for windows or internal plumbing fixtures, as long as the essential character of a building is present.

Codes often confused with 9406.10
Common mistake. A frequent error is classifying these structures under HS code 4418, which covers builders' joinery and carpentry of wood. While 4418 includes parts of buildings like beams or window frames, it does not cover complete or incomplete buildings presented as a single shipment. Another confusion arises with HS code 9406.90, which is a residual category for prefabricated buildings made of materials other than wood, such as steel or concrete.

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).
