7404.00.30.55 - Other

This HTS classification, 7404.00.30.55, specifically covers "Other" waste and scrap derived from copper-zinc base alloys (brass) that do not meet the criteria of the sibling category. It encompasses brass waste and scrap that has a copper content of less than 94 percent by weight, and crucially, contains a lead content of 0.3 percent or less by weight. These materials typically arise from manufacturing processes involving brass, such as machining, stamping, or fabrication, and are intended for recycling or remelting.

The key differentiator for this subcategory lies in its specific lead content limitation. Unlike the sibling category, 7404.00.30.45, which is designated for brass waste and scrap *containing more than 0.3 percent of lead*, this classification is for those with a lead content *not exceeding* 0.3 percent. This distinction is critical for customs purposes as lead content can significantly impact the value, recyclability, and potential environmental regulations associated with copper scrap.

As a leaf node in the HTS structure, there are no further subcategories beneath this code. Therefore, the classification is definitively determined by the material (copper-zinc base alloy scrap), its general copper content (less than 94 percent), and the specific lead content (0.3 percent or less). Importers and exporters should carefully analyze their materials' composition to ensure accurate classification under this specific code.
