Import Tips

• Provide mill test certificates confirming alloy composition meets aluminum alloy definition (Al predominant, other elements >1% total)

• Ensure documentation specifies 'foundry ingot' use per statistical note 4 to avoid reclassification as general unwrought aluminum

• Check for country-of-melt origin; some origins may face quotas or higher duties on aluminum products
