9406.90.01 - Other

This HTS category, 9406.90.01, encompasses prefabricated buildings that do not fall under the more specific categories for wood or steel modular building units. It serves as a residual classification for prefabricated structures, allowing for the proper import and export treatment of a variety of building types constructed off-site.

Distinguishing this category from its siblings is crucial. Unlike 9406.10.00.00, which is exclusively for prefabricated buildings constructed primarily of wood, and 9406.20.00.00, designated for modular building units made of steel, this category covers prefabricated buildings constructed from other materials. This includes, but is not limited to, buildings where the primary structural components or cladding are made of plastics, aluminum, concrete, or composite materials.

The subcategories within 9406.90.00 provide further refinement based on material composition. The "Of metal" subcategory specifically addresses prefabricated buildings where metal, other than the modular steel units, forms the primary construction material. The "Other" subcategory, to which 9406.90.01 belongs, acts as a further catch-all for any remaining prefabricated buildings not classified elsewhere, ensuring comprehensive coverage.
