7605 - Aluminum wire:

This HTS category, 7605, specifically classifies aluminum wire. This encompasses wire made from pure aluminum or aluminum alloys, irrespective of its cross-sectional shape, as long as it is considered "wire." Common applications include electrical conductors, mechanical components, and materials for manufacturing other articles. The key determinant for inclusion here is the material composition and its form as wire.

Distinguishing 7605 from its sibling categories at the Section XV level is crucial. While siblings in Chapter 01, for instance, deal with live animals, or those in other chapters might cover different metals or articles not primarily composed of aluminum, 7605 is exclusively focused on aluminum in its wire form. It differentiates itself from other aluminum articles in Chapter 76, such as plates, sheets, foil, tubes, or bars, by its characteristic length and relatively small cross-sectional dimension.

Within 7605, further subclassification is made based on the composition of the aluminum. The subcategories distinguish between wire that is "Of aluminum, not alloyed," meaning it is made from relatively pure aluminum, and wire that is "Of aluminum alloys," which are mixtures of aluminum with other elements to achieve specific properties. This distinction is important for tariff purposes, as different alloy compositions can influence the value and intended use of the wire, leading to varied duty rates.
