7404.00.30.90 - Other

This HTS code, 7404.00.30.90, covers "Other" waste and scrap of copper alloys. Specifically, it pertains to spent anodes and waste and scrap with a copper content of less than 94 percent by weight, which are composed of copper alloys but do not fall under the more specific alloy categories of copper-zinc base alloys (brass) or copper-tin base alloys (bronze). This includes a broad range of discarded or scrap materials where copper is a significant component but the specific alloy composition is not brass or bronze, or the material is otherwise not enumerated in more specific subheadings.

The distinction between this category and its siblings lies in the specific composition of the copper alloy. While 7404.00.30.60 covers brass waste and scrap, and 7404.00.30.65 covers bronze waste and scrap, this subheading (7404.00.30.90) is for all other copper alloy scrap that does not fit those defined categories. This might include alloys with other base metals such as nickel, aluminum, or silicon, provided they are still classified as copper alloys under Chapter 74 and meet the general criteria for copper waste and scrap with less than 94% copper content.

As this is a leaf node within the HTS classification structure, there are no further subcategories. Therefore, accurate classification under this code relies on a thorough understanding of the material's composition and the exclusion of materials that are specifically classified under preceding sibling categories. Importers and exporters should ensure that the waste or scrap material is not primarily brass or bronze, and that it meets the definition of copper waste and scrap with less than 94% copper content by weight.
