7409.11 - In coils:

This HTS category, 7409.11, specifically covers copper plates, sheets, and strip of refined copper that are supplied in coils and have a thickness exceeding 0.15 mm. The defining characteristic of this classification is its coiled form, differentiating it from other forms of copper plates, sheets, and strip not presented in coils.

Within the broader scope of refined copper plates, sheets, and strip (7409.10), this subcategory is distinguished from its sibling, 7409.19, which encompasses similar materials but are not presented in coils. Therefore, the coiled format is the primary criterion for classification under 7409.11.

The subcategories within 7409.11 further refine the classification based on thickness. This includes 7409.11.10.00 for materials with a thickness of 5 mm or more, and 7409.11.50 for those with a thickness of less than 5 mm. These subdivisions allow for more precise identification and potential tariff differentiation based on specific physical dimensions relevant to various industrial applications.
