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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the panels are used as flooring blocks
Flooring blocks are a sibling tariff item, distinguished by their use in flooring applications.
If the panels are part of a prefabricated building structure
Chapter 94 covers prefabricated buildings, which may apply if the panels are integral to a building system.

Import Tips & Compliance
• Ensure the panels are fired after shaping, as unfired or low-temperature products are excluded from Chapter 69
• Provide technical specifications showing the firing temperature and the panel's function as a filler or support element
• Verify that the panels are not classifiable as prefabricated buildings (Chapter 94) or electrical insulating fittings (heading 8547), which would change the classification
Related Products under Tariff item 6904.90.20
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.
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.
