HS Code for Prefab house

Prefabricated houses that are not constructed of wood are classified under HS code 9406.90. This classification is part of Chapter 94, which covers furniture, bedding, and prefabricated buildings. A product is considered a prefabricated building if it is finished in a factory or supplied as a kit of parts to be assembled on-site. The 9406.90 code is a residual category for structures made of steel, aluminum, concrete, or plastics. The primary reason for this classification is the intended use of the structure as a permanent or semi-permanent habitation or workspace. To qualify, the unit must have the essential character of a building, including walls, a roof, and usually floor elements. This code excludes simple sheds or small tool boxes that do not meet the definition of a building structure.

Common Misclassification

The most common error is using HS code 9406.10, which is strictly reserved for prefabricated buildings made of wood. Another frequent mistake is classifying steel prefab houses under 7308.90 (structures of iron or steel). While 7308 covers parts of structures, 9406 is the specific heading for complete or nearly complete buildings. If the shipment contains only the steel frame without walls or roofing, 7308 might apply, but a complete kit must be classified under 9406.90.
