7409.21.00 - In coils

This HTS category, 7409.21.00, specifically covers copper-zinc base alloy (brass) plates, sheets, and strip that are manufactured in coils. The defining characteristic here is not only the material composition (brass) but also the form in which it is presented – wound into coils for ease of transport and subsequent processing. This includes a wide range of brass products that will be further unrolled or cut for various industrial and commercial applications.

This classification is distinguished from its sibling category, 7409.29.00, by the crucial factor of presentation. While both cover brass plates, sheets, and strip of a thickness exceeding 0.15 mm, 7409.29.00 encompasses those not presented in coils, meaning they are likely individually cut or otherwise individually packaged. Therefore, the determining factor for classification under 7409.21.00 is the coiled form.

The subcategories within 7409.21.00 further refine this classification based on the thickness of the brass in coils. The main subdivisions differentiate between brass coils that are 5 mm or more in thickness and those that are less than 5 mm in thickness. This distinction is important for specific trade regulations and potential end-use considerations, allowing for more granular tracking and potential duty assessments.
