7601.10.30.00 - Of uniform cross section throughout its length, the least cross-sectional dimension of which is not greater than 9.5 mm, in coils

This HTS category, 7601.10.30.00, specifically classifies unwrought aluminum that is not alloyed and is of a uniform cross-section throughout its length. The defining characteristic of this material is that its smallest cross-sectional dimension does not exceed 9.5 mm, and it is presented in coils. This typically includes wire rod or similar forms of pure aluminum produced through extrusion or drawing processes, ready for further manufacturing.

This classification is distinct from its sibling category, 7601.10.60, which covers "Other" unwrought, unalloyed aluminum. The sibling category would encompass unwrought aluminum not meeting the specific dimensional and form requirements of 7601.10.30.00, such as ingots, bars, or rods with larger cross-sections or not presented in coils. Therefore, the critical differentiators are the specific dimensions (not greater than 9.5 mm) and the presentation in coils.

As this HTS code is a leaf node, there are no further subcategories. This means that any unwrought, unalloyed aluminum meeting the stated criteria of uniform cross-section not exceeding 9.5 mm and presented in coils will be classified directly under this specific code. The classification relies heavily on the physical characteristics and presentation of the aluminum material itself.
