7404.00.60.90 - Other

This HTS category, 7404.00.60.90, covers "Other" copper waste and scrap that are not specifically classified under other subheadings. It is a residual category for copper alloy scrap, meaning it captures materials that do not fit into more defined alloy types. This includes scrap from any copper alloy not explicitly listed, provided it meets the general definition of waste and scrap of copper alloys as outlined in Chapter 74.

To distinguish this category from its siblings, consider the specific alloy compositions. HTS 7404.00.60.60 pertains to scrap of copper-zinc base alloys, commonly known as brass. Similarly, HTS 7404.00.60.65 specifically covers scrap from copper-tin base alloys, or bronze. Therefore, category 7404.00.60.90 is for copper alloy scrap where the primary alloying elements are neither zinc nor tin, or where the alloy composition is mixed or not readily identifiable as a specific brass or bronze.

As a leaf node, this classification does not have further subcategories. Classification into this "Other" category relies on the absence of specific alloy identifiers that would place the material under a more granular subheading. It serves as a catch-all for copper alloy waste and scrap that does not meet the criteria for more narrowly defined categories within the same hierarchical level.
