7604.29.30.60 - Heat-treatable industrial alloys of a kind described in statistical note 7 to this chapter

This HTS classification covers aluminum alloy bars and rods that are heat-treatable and are not specifically classified elsewhere. These are industrial alloys, meaning they are designed for manufacturing and construction purposes rather than consumer end-products. The defining characteristic for this category is that the alloy's properties are enhanced through controlled heating and cooling processes, imparting increased strength or other desired mechanical characteristics.

This category is distinguished from its sibling, 7604.29.30.30, by the specific type of heat-treatable alloy. While both are heat-treatable, the parent category 7604.29.30.30 is reserved for "high-strength" heat-treatable alloys explicitly described in statistical note 6. This current classification, 7604.29.30.60, encompasses other heat-treatable industrial alloys that do not meet the "high-strength" designation of the sibling category, as further defined by statistical note 7 to Chapter 76. The sibling category 7604.29.30.90 is a residual classification for all other bars and rods of aluminum alloys not otherwise specified.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification is determined by the material composition (aluminum alloy), form (bars and rods), and the specific heat-treatable nature of the industrial alloy as defined by statistical note 7. Examples of alloys that might fall here include those used in general manufacturing, automotive components, or aerospace applications where enhanced properties through heat treatment are required, but not necessarily the highest strength levels reserved for the sibling category.
