This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is aluminum oxide not meeting artificial corundum definition
Aluminum oxide is classified separately.
If the mullite is natural rather than fused
Natural mullite falls under Chapter 25.
