7604.29.10.90 - Other

This HTS code, 7604.29.10.90, encompasses "Other" profiles of aluminum alloys that do not fit into the more specific "heat-treatable industrial alloys" category. These profiles are manufactured from aluminum alloys, meaning they contain at least one other element in addition to aluminum, altering their physical properties compared to pure aluminum. The key characteristic of this subcategory is the exclusion of those alloys specifically defined as heat-treatable industrial alloys according to statistical note 7 of chapter 76.

The distinction between this category and its sibling, 7604.29.10.10, lies precisely in the material composition and its treatability. While 7604.29.10.10 is reserved for profiles made from heat-treatable industrial aluminum alloys, 7604.29.10.90 is for all other aluminum alloy profiles. This implies that classification here hinges on understanding the specific metallurgical properties and the absence of heat-treatable characteristics as defined by the relevant statistical notes.

As a leaf node within the HTS, this category does not have further subdivisions. Therefore, classification under 7604.29.10.90 requires a thorough examination of the aluminum alloy profile to ensure it meets the criteria of being an "other profile" and not falling under any more narrowly defined categories at the preceding levels. Examples might include certain decorative extrusions, non-industrial structural components, or other shaped aluminum alloy articles where the alloy is not specifically heat-treatable for industrial applications.
