A356.1 Aluminum Foundry Ingot from Canada

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.

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
