7407.10 - Of refined copper:

This HTS category, 7407.10, specifically addresses bars, rods, and profiles manufactured from refined copper. Refined copper, as defined by its purity, is the primary material characteristic here. This includes articles that are not hollow and possess a uniform cross-sectional shape throughout their length, whether they are circular, square, rectangular, or hexagonal. The intended applications for these items are broad, ranging from electrical components and plumbing to architectural elements and general manufacturing.

Distinguishing this category from its sibling, 7407.20 ("Of copper alloys"), is crucial. While both sections cover bars, rods, and profiles, 7407.10 is exclusively for products made from pure, refined copper. Category 7407.20, in contrast, encompasses similar shapes but is composed of copper mixed with other metals to form alloys. Therefore, the metallurgical composition is the key differentiator.

The subcategories within 7407.10 further refine the classification. The distinction between "Profiles" and "Bars and rods" (7407.10.50) depends on the geometric complexity and typical usage of the cross-sectional shape. Bars and rods generally refer to simpler, solid cross-sections, whereas "Profiles" may encompass more intricate or specialized shapes designed for specific structural or functional purposes. This subdivision allows for more precise tariff application based on the product's form and potential end-use.
