Fire Clay Powder from China
Refractory-grade fire clay ground into powder for brick manufacturing and high-temperature applications. It is not calcined into mullite or chamotte, so it remains under 'other clays' as a natural clay.

Import Tips
• Confirm the clay is not calcined, as calcined fire clay becomes chamotte or dinas earth (heading 25.08.30)
• Provide the particle size distribution to show it is ground, not chemically treated
• Check if the powder is blended with other materials, which could alter classification
