Insulating Refractory Brick from China
Insulating refractory bricks are lightweight, fired from vermiculite-clay mixes to reduce heat loss in furnace walls and backup linings. They feature low thermal conductivity and high porosity, making them ideal for thermal insulation in high-temperature equipment. This product falls under tariff item 6902.90.00 as a refractory ceramic constructional good other than those of siliceous fossil meals.

Import Tips
• Confirm the bricks are fired and not merely dried, as low-temperature processing excludes them from Chapter 69
• Provide thermal conductivity data to support the refractory classification
• Ensure the vermiculite content is documented for CBSA review
