7601.20.90.45 - Of uniform circular cross section throughout its length, the foregoing comprised of billets, not in coils

This HTS category, 7601.20.90.45, covers unwrought aluminum alloys that have a uniform circular cross-section throughout their length. Crucially, these goods are specifically in the form of billets and are not presented in coils. This designation applies to aluminum alloys that do not meet the specific criteria for other, more narrowly defined subheadings within the unwrought aluminum classification.

The primary distinction for this category lies in its form factor and the absence of specific alloying elements that would place it elsewhere. Unlike the sibling category 7601.20.90.60, which specifically identifies secondary aluminum containing 0.03 percent or more by weight of lead, this category encompasses all other unwrought aluminum alloy billets of uniform circular cross-section that do not meet that lead content threshold. The focus here is on the physical presentation as a billet of a specific shape, rather than a particular secondary origin or a defined lead percentage.

As a leaf node, this category has no further subcategories. Therefore, classification within 7601.20.90.45 is definitive when the goods are unwrought aluminum alloy billets with a uniform circular cross-section, not in coils, and do not qualify for any more specific classification based on alloying content or form. Examples would include various standard aluminum alloy billets used in manufacturing processes requiring this specific shape and presentation.
