7606.12.30.91 - Heat-treatable industrial alloys of a kind described in statistical note 7 to this chapter

This HTS classification, 7606.12.30.91, covers rectangular plates, sheets, and strip of aluminum alloys that have undergone heat treatment and are specifically designated as industrial alloys according to statistical note 7 to Chapter 76. These products must have a thickness not exceeding 6.3 mm and are not clad. The "other" designation within this subcategory indicates that they do not fit into any more specific classifications at this level, but still meet the criteria of being heat-treatable industrial alloys.

This specific classification is distinguished from its sibling, 7606.12.30.96, by the precise definition of "industrial alloys" as outlined in the aforementioned statistical note. While both are considered "other" within their respective branches, 7606.12.30.91 is reserved for those alloys meeting stringent criteria for industrial applications due to their heat-treatable properties. The core differentiator lies in the specific metallurgical composition and intended industrial purpose as defined by the statistical note, rather than purely dimensional or cladding characteristics.

As this is a leaf node in the HTS, there are no further subcategories. Therefore, classification under 7606.12.30.91 relies on a careful examination of the material's composition to confirm it qualifies as a heat-treatable industrial alloy, alongside the physical attributes of rectangular shape and thickness not exceeding 6.3 mm. Importers and exporters should consult statistical note 7 for detailed guidance on alloy types and their suitability for industrial use to ensure correct classification.
