Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If slabs specifically designated for slab zinc category
Casting-grade zinc has form-specific subheadings within the same purity range.
If with alloying elements exceeding chapter note thresholds
Even minor alloying (>2.5% other metals) requires alloyed zinc classification.
If as zinc skimmings or zinc dross from casting operations
Processing residues classify as leached slags, not primary unwrought metal.

Import Tips & Compliance
• Obtain zinc content certificates from accredited labs meeting ASTM standards
• Declare exact weight and dimensions; volumetric shipping can inflate duties
• Separate from alloyed zinc in storage to prevent cross-contamination claims
