A356.0 Aluminum Alloy Ingot from China

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
