6904.10.00.40 - Other

This category, HTS Code 6904.10.00.40, specifically covers "Other" building bricks that do not fall under the more specific "Heat insulating" classification (6904.10.00.30). It encompasses a wide range of ceramic bricks intended for construction purposes, including solid bricks, those with non-insulating perforations, and any other configurations not explicitly defined elsewhere within this heading. These items are primarily characterized by their use in the erection of buildings and structures, typically composed of fired clay or similar ceramic materials.

The distinction from its sibling, "Heat insulating" bricks, lies in their primary function and material composition. While heat insulating bricks are designed with properties specifically to reduce thermal transfer, the bricks classified under "Other" are generally for structural purposes, load-bearing, or decorative finishes where thermal insulation is not the defining characteristic. The classification hinges on the material's inherent thermal resistance and its intended application in preventing heat flow.

As this is a leaf node within the Harmonized Tariff Schedule, there are no further subcategories. Therefore, classification into this specific code requires careful consideration of the brick's physical attributes, intended use in construction, and confirmation that it does not meet the criteria for any other more specific classification under heading 6904, particularly the "Heat insulating" subcategory. Examples could include standard solid red bricks, engineering bricks for load-bearing walls, or facing bricks for exterior cladding, provided they are not designed for thermal insulation.
