Casting-Grade Zinc Ingots
High-purity zinc ingots specifically refined for casting applications, containing less than 99.99% zinc by weight and not alloyed. These ingots are melted and poured into molds to produce die-cast parts for automotive and consumer goods. Classified under HTS 7901.12.10.00 as unwrought, non-alloyed zinc of casting grade.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purity meets or exceeds 99.99% zinc
Higher purity non-alloyed zinc shifts to the refined zinc subheading in the same unwrought category.
If when zinc content is alloyed with >2.5% other elements
Zinc alloys, as defined in chapter notes, fall under separate alloyed zinc provisions.
If containing significant impurities or slag from smelting
Zinc dross or residues are classified as ash and residues rather than unwrought metal.

Import Tips & Compliance
• Verify zinc purity via certified lab analysis to confirm <99.99% and non-alloyed status per chapter notes
• Provide mill test certificates documenting composition to avoid misclassification as higher-purity zinc
• Ensure proper hazardous material declarations if trace impurities trigger shipping regulations
