More Specific Codes
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 alumina is doped for electronics and cut into discs or wafers
Doped chemical elements in wafer form fall under Chapter 38.
