Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purity 97.5% to 99.989%
Subheading covers non-alloyed zinc not qualifying for the 99.99% threshold.
If intentionally alloyed compositions
Chapter (b) note defines alloys by predominant zinc with >2.5% other elements.
If chemically treated for lab use
High-purity zinc for chemical analysis may classify as inorganic base compounds.
