7409.21.00.90 - Other

This HTS category, 7409.21.00.90, encompasses other plates, sheets, and strip of copper-zinc base alloys (brass) that are supplied in coils, have a thickness of less than 5 mm, and a width of less than 500 mm. These products are manufactured from brass, a copper alloy predominantly containing zinc, and are presented in a continuous rolled form. The "Other" designation indicates that within this specific subset of brass coils meeting the thickness and width criteria, there are no further material or dimensional subdivisions to distinguish them.

To clarify its position, this category is distinct from sibling category 7409.21.00.75, which specifically covers brass plates, sheets, and strip in coils with a thickness of less than 1.6 mm. Therefore, category 7409.21.00.90 includes brass coils that are between 1.6 mm and 5 mm in thickness, provided their width remains under 500 mm. This finer distinction is crucial for accurate tariff application, as different thickness ranges can reflect varying manufacturing processes and intended end-uses.

As this is a leaf node in the HTS classification, there are no further subcategories. The classification is complete at this level, signifying that all brass plates, sheets, and strip meeting the specified criteria of being in coils, less than 5 mm in thickness, and less than 500 mm in width, and not falling under any more specific subheadings, are classified here. Practical application will focus on verifying the alloy composition (copper-zinc base), form (plates, sheets, strip in coils), overall thickness (less than 5 mm, but not less than 1.6 mm), and width (less than 500 mm).
