Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing fluoride forming aluminum fluorohydroxide
Fluorinated aluminum compounds shift to Chapter 28 fluorides heading due to chemical composition.
If blended with organic stabilizers for specific uses
Preparations with added organics exceed chemically defined scope, falling into chemical preparations.
If calcined to high-temperature form resembling metalloids
Heat-treated forms may classify as rare-earth metal salts if processed beyond basic hydroxide.
