A356.0 Aluminum Alloy Ingot from Japan
A356.0 is a hypoeutectic aluminum-silicon alloy used primarily for casting applications in automotive and aerospace industries. It contains approximately 7% silicon and 0.3% magnesium, making aluminum the predominant element by weight, exceeding the purity limits for non-alloyed aluminum. Classified under 7601.20.90 as unwrought aluminum alloy in other forms not specified elsewhere.

Import Tips
• Verify chemical composition certification to confirm alloy status per subheading note (b), as silicon and magnesium exceed non-alloyed limits
• Provide mill test reports documenting aluminum predominance and element contents to avoid misclassification as scrap or wrought forms
