A356.1 Aluminum Foundry Ingot
A356.1 is a hypoeutectic aluminum-silicon alloy ingot designed for sand casting applications in automotive and aerospace components. It meets the criteria for aluminum alloys under HTS 7601 as it contains silicon and other elements exceeding non-alloyed limits, and qualifies as a foundry ingot per statistical note 4 for high-purity casting stock. These ingots are melted in foundries to produce intricate castings like cylinder heads.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not qualifying under statistical note 4 for foundry-specific purity
Other aluminum alloy ingots fall under this statistical breakout if not specifically for foundry casting applications.
If containing 99%+ pure aluminum without alloying elements
Non-alloyed aluminum unwrought forms use Chapter 7601.10 when purity exceeds alloy thresholds.
If shaped into powders rather than solid ingot form
Aluminum powders and flakes from alloys are classified in 7603 based on physical form, not ingot.

Import Tips & Compliance
• 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
