Products classified under Tariff item 6904.90
Clay Ceramic Retaining Wall Bricks
Fired clay bricks specifically shaped for retaining walls in landscaping and civil engineering projects. These bricks are shaped from inorganic, non-metallic materials and fired above 800°C, meeting the Chapter 69 requirements for ceramic building products.
6904.90.10Extruded Ceramic Partition Blocks
Extruded and fired ceramic blocks designed for lightweight interior partitions in commercial buildings. These blocks are shaped from clay and fired at high temperatures, making them ceramic building products under Chapter 69, and are not classifiable as support or filler tiles.
6904.90.10Fireplace Ceramic Backer Bricks
High-density ceramic bricks used behind firebrick linings in fireplaces for structural support and heat distribution. These fired clay products are not refractory bricks (heading 6902) and are classifiable as other ceramic building bricks under this tariff item.
6904.90.10Perforated Ceramic Wall Blocks
Perforated fired ceramic blocks for non-load-bearing partition walls, allowing ventilation and wiring passage. These building components are shaped from clay and fired after shaping, meeting Chapter 69 requirements and classifiable as other ceramic building bricks.
6904.90.10Red Clay Ceramic Building Bricks
Fired red clay bricks used for constructing exterior and interior walls in residential and commercial buildings. These bricks are shaped from clay mixtures and fired above 800°C, classifying them as ceramic building bricks under this tariff item.
6904.90.10Standard Ceramic Chimney Bricks
Fired ceramic bricks shaped for chimney construction, providing weather resistance and structural integrity. These bricks are not refractory linings and are classifiable as other ceramic building bricks under this tariff item.
6904.90.20Insulating Ceramic Filler Bricks
Insulating ceramic filler bricks are low-density bricks fired from lightweight clay aggregates at temperatures exceeding 800°C, giving them thermal insulation properties. They are used as fillers in composite building panels, providing structural support and insulation. These products fall under tariff item 6904.90.20 as support or filler tiles, as they are fired ceramic products not classified as flooring blocks.
6904.90.20Porous Ceramic Filler Tiles
Porous ceramic filler tiles are lightweight, porous tiles fired from clay and siliceous materials at high temperatures, designed to reduce weight in wall construction or precast concrete panels. They serve as support or filler elements in building assemblies, not as surface coverings. These tiles meet the criteria for tariff item 6904.90.20 as support or filler tiles, being fired ceramic products.
6904.90.20Structural Ceramic Filler Panels
Structural ceramic filler panels are pre-shaped fired ceramic panels used as fillers in structural insulated panels for energy-efficient buildings. They are fired at high temperatures to achieve structural integrity and provide support within the panel system. These panels qualify under tariff item 6904.90.20 as support or filler tiles, as they are fired ceramic products not classified as flooring blocks.
6904.90.20Unglazed Ceramic Support Tiles
Unglazed ceramic support tiles are fired clay tiles that provide structural support in multi-layer flooring systems or wall assemblies, without any glaze coating. They are fired to hardness at temperatures exceeding 800°C, making them durable and suitable for load-bearing applications. These tiles fall under tariff item 6904.90.20 as support or filler tiles, as they are not flooring blocks and are fired ceramic products.
