7606.12.30.15 - High-strength heat-treatable alloys of a kind described in statistical note 6 to this chapter

This HTS code, 7606.12.30.15, specifically classifies rectangular plates, sheets, and strip of aluminum alloys that are not clad, have a thickness exceeding 6.3 mm, and are comprised of high-strength heat-treatable alloys as defined in statistical note 6 to Chapter 76. These materials are engineered for applications requiring superior mechanical properties achieved through specific heat treatment processes, distinguishing them from alloys designed for different performance characteristics.

It is crucial to differentiate this category from its siblings. Unlike 7606.12.30.25, which covers heat-treatable industrial alloys described in statistical note 7, this code pertains to a distinct set of high-strength alloys with unique metallurgical properties and applications. Furthermore, it is separate from the "Other" category (7606.12.30.35), which serves as a residual classification for non-clad, rectangular aluminum alloy plates, sheets, and strip exceeding 6.3 mm in thickness that do not meet the criteria for either statistical note 6 or 7.

As a leaf node, this classification does not have further subcategories. Therefore, the classification decision hinges on whether the specific aluminum alloy product meets the precise definition of "high-strength heat-treatable alloys of a kind described in statistical note 6 to this chapter." Importers must carefully consult statistical note 6 and verify the alloy composition and heat treatment of their goods to ensure accurate classification under this code.
