7409.11.50.10 - Of a width of 500 mm or more

This HTS category, 7409.11.50.10, specifically classifies rolled copper in coils that is derived from refined copper and has a thickness of less than 5 mm. The defining characteristic of this classification is its width, which must be 500 mm or greater. These are typically flat, continuous lengths of copper used in various industrial applications, such as electrical wiring, heat exchangers, and construction materials, where large, continuous sheets are required.

Distinguishing this category from its sibling, 7409.11.50.50, is solely based on width. While both cover rolled refined copper coils under 5 mm thick, the sibling category is for products with a width *less* than 500 mm. Therefore, the critical differentiator for classification into 7409.11.50.10 is the substantial width of the copper coil.

As a leaf node in the HTS structure, this category does not have further subcategories. Classification at this level is precise, relying on the stated physical attributes of refined copper coils: its form (coils), material purity (refined copper), thickness (less than 5 mm), and crucially, its width (500 mm or more). This specific combination of criteria ensures accurate customs declaration and duty assessment for these broad copper products.
