7404.00.60.65 - Of copper-tin base alloys (bronze)

This HTS classification, 7404.00.60.65, specifically covers copper waste and scrap that are derived from copper-tin base alloys, commonly known as bronze. This designation includes materials where the primary alloying element with copper is tin, forming bronze. These materials are typically in a form suitable for remelting or reprocessing into new copper articles, such as ingots, powders, or broken pieces of bronze products.

Distinguishing this category from its sibling, 7404.00.60.10 (Of copper-zinc base alloys (brass)), is the elemental composition of the alloy. While both are categorized under copper alloys, this specific code targets bronze, defined by its copper-tin composition, whereas the sibling code applies to brass, which is characterized by its copper-zinc content. The other sibling at this level, 7404.00.60.90, serves as a catch-all for any other copper alloy waste and scrap not specifically enumerated.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification under 7404.00.60.65 relies solely on the definitive presence of a copper-tin base alloy in the waste or scrap material. Importers and exporters must accurately ascertain the elemental composition to ensure correct classification and avoid discrepancies during customs procedures.
