HS Code 9406.90 – Buildings; prefabricated, not of wood
HS code 9406.90 is the 6-digit subheading for buildings, prefabricated, not of wood. It is used for prefabricated concrete panel homes, composite panel modular buildings, prefabricated plastic kiosks, steel-frame buildings with non-wood cladding and insulated sandwich panel structures.
What HS 9406.90 covers
This HS code serves as a residual category for prefabricated buildings made from materials other than wood, encompassing a wide array of construction types. This includes structures primarily composed of concrete, composite panels, plastics, or combinations thereof, designed for quick assembly on-site. These buildings cater to diverse needs, from residential and commercial applications to industrial and emergency shelters. Importers are typically countries seeking efficient and cost-effective construction solutions, often in regions with rapid urbanization, disaster recovery efforts, or specialized industrial requirements. Exporters include nations with advanced manufacturing capabilities in various building materials, such as China, Germany, and the United States. Key factors in this trade include material innovation, energy efficiency standards, transportation costs for large components, and adherence to local building codes. The versatility of materials allows for tailored solutions, addressing specific climate conditions, aesthetic preferences, and functional demands.

Codes often confused with 9406.90
Common mistake. This code can be confused with 940610 (prefabricated buildings of wood) or 940620 (modular steel units) if the primary material isn't carefully identified. It's the catch-all for non-wood, non-steel-modular prefabricated buildings, requiring careful material assessment.

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).
