Unglazed 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.

Import Tips & Compliance
• Confirm that the tiles are fired above 800°C and not merely dried or cured, as lower-temperature products are excluded from Chapter 69
• Document the tile's intended use as a support element, not as a surface covering, to support classification under this tariff item
• Check that the tiles are not classifiable as flooring blocks (6904.90.10) or as articles of Chapter 94, such as furniture or lighting fittings

Insulating 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.
Porous 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.
Structural 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.
