Buildings, prefabricated, of wood.
Classification of prefab wood house under HS 9406.10
The classification of a prefabricated wood house under HS code 9406.10 is strictly governed by the General Interpretative Rules (GIR) and the specific legal notes of Chapter 94. According to Note 4 to Chapter 94, prefabricated buildings are defined as structures that are either fully finished in a factory environment or presented as a kit of parts intended for assembly on a specific site. For a product to fall under the 9406.10 subheading, wood must be the constituent material that gives the building its essential character, typically forming the primary load-bearing frame or the majority of the exterior wall surface area. This classification applies to a wide range of wooden structures, provided they are designed to function as buildings—meaning they offer an enclosed space for human habitation, work, or storage. The Harmonized System distinguishes these from simple wooden structures or joinery by the fact that they are complete or nearly complete architectural units. Even if the building is shipped without certain non-essential components like floor coverings or interior paint, it remains classified here as long as the wooden structural integrity is present. This code is vital for international trade statistics, as it allows customs to monitor the movement of timber-based housing solutions separately from steel or concrete alternatives.

Codes often confused with 9406.10
Common mistake. A frequent point of confusion involves HS code 4418, which covers builders' joinery and carpentry of wood. While 4418 includes components like doors, windows, and beams, it does not cover complete buildings. If the shipment consists only of wooden panels without the character of a finished building, 4418 is appropriate; however, if it is a complete kit, 9406.10 must be used. Additionally, 9406.90 is often mistakenly used for wooden houses, but that code is strictly reserved for buildings made of materials other than wood, such as metal or plastic.

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).
