Import Tips
• Provide mill test certificates confirming alloy composition meets chapter note (b) definitions to avoid reclassification as non-alloyed aluminum
• Declare exact chemical analysis including silicon, magnesium, and iron content; discrepancies can lead to penalties or duty adjustments
• Ensure ingots are free of impurities exceeding specified limits to prevent scrutiny under aluminum purity standards
