Cast aluminum cookware (lines such as 7615102015, 7615102025, 7615104000, 7615105020, 7615105040) is formed by pouring molten aluminum into a mold, producing thicker, heavier pieces typically used for skillets and Dutch ovens. Non-cast (wrought) aluminum cookware is formed from rolled sheet or drawn aluminum and tends to be lighter. The distinction is a primary classification criterion within 761510, and importers should obtain manufacturing process documentation from suppliers to support the correct line assignment.

Thin-gauge aluminum containers for food preparation, baking, reheating, or storage (7615107125, covering foil containers in the 0.04–0.22 mm thickness range) are classified as aluminum articles, not food-contact materials subject to a separate admissibility regime. However, if they are imported pre-filled with food, the contents would trigger FDA food import requirements. Importers of empty containers should ensure invoices clearly describe them as unfilled packaging to avoid unnecessary examination.
