7601.20.90.85 - Foundry ingot of a kind described in statistical note 4 to this chapter

This HTS classification, 7601.20.90.85, specifically covers foundry ingots of aluminum alloys that meet the criteria outlined in statistical note 4 to Chapter 76. These are typically cast in a shape intended for direct remelting in foundries to produce a variety of aluminum alloy castings. Their defining characteristic is their suitability for foundry melt operations, often implying specific purity levels or alloy compositions tailored for casting processes, as detailed in the referenced statistical note.

Distinguishing this category from its siblings, 7601.20.90.75 (remelt scrap ingot) and 7601.20.90.80 (sheet ingot or slab), is crucial. While all are unwrought aluminum alloys, foundry ingots are produced with specific metallurgical properties and forms to optimize their use in casting, differentiating them from less refined remelt scrap or larger slabs intended for subsequent fabrication processes like rolling. The "other" designation at this granular level signifies that these are specific types of foundry ingots not otherwise enumerated within statistical note 4's parameters, but still meeting its general definition.

As this classification represents a leaf node within the HTS structure, there are no further subcategories to explore. Therefore, the focus remains on understanding the precise definitions and requirements stipulated by statistical note 4 to Chapter 76 to ensure accurate classification. Importers and exporters should consult this statistical note for detailed guidance on the characteristics that qualify an aluminum alloy ingot for this specific designation, as opposed to other forms of unwrought aluminum alloys.
