Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purity is 99.99% or higher
Zinc ≥99.99% purity classifies as primary slabs under 7901.11, distinct from 'other' lower purities in 7901.12.50.
If total other elements exceed 2.5% by weight
Becomes zinc alloys per chapter note (b) when non-zinc elements >2.5%, shifting to zinc alloys heading 7901.20.
If in granular or powder form from smelting residues
Zinc residues or granules not meeting unwrought definitions move to Chapter 26 for mineral products.

Import Tips & Compliance
• Provide mill test certificates verifying zinc content between 97.5% and 99.99% to confirm 'not alloyed' status and avoid reclassification
• Declare exact purity percentage on entry documents; impurities over 2.5% total may trigger alloy review under chapter note (b)
