Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the tabular alumina is imported as a pure oxide without cement binders
Pure alumina is a separate chemically defined compound of chapter 28.
If the cement is for non-refractory applications
General-purpose cements are classified under prepared binders.
