7604.29.30.30 - High-strength heat-treatable alloys of a kind described in statistical note 6 to this chapter 🖩

This HTS category, 7604.29.30.30, specifically classifies aluminum bars and rods that possess a round cross-section and are made from aluminum alloys. Crucially, these alloys must be considered "high-strength" and "heat-treatable," as further defined within statistical note 6 to Chapter 76. This designation implies specific metallurgical properties achieved through heat treatment processes, leading to enhanced tensile strength and performance characteristics required for demanding applications.

This subcategory is distinguished from its siblings by the precise combination of physical form (round cross-section) and the inherent properties of the aluminum alloy. Sibling category 7604.29.30.60, for instance, also covers heat-treatable industrial alloys but is differentiated by its reference to statistical note 7, suggesting a different set of alloy compositions or applications. Category 7604.29.30.90 is a residual category for any other bars and rods not fitting the more specific classifications.

As this is a leaf node within the HTS structure, there are no further subdivisions. Therefore, classification into this particular code hinges on meeting all the preceding criteria: the product being an aluminum bar or rod, having a round cross-section, being an alloy, and specifically qualifying as a high-strength, heat-treatable alloy according to statistical note 6. Examples of products that might fall here include specialized round aluminum rods used in aerospace components, high-performance automotive parts, or precision engineering applications where superior strength and durability are paramount.
