7404.00.30.65 - Of copper-tin base alloys (bronze)

This HTS classification covers waste and scrap specifically comprised of copper-tin base alloys, commonly known as bronze. This category is intended for materials that have reached the end of their usable life and are destined for recycling or reprocessing, where their primary metallic composition is a blend of copper and tin. The key defining characteristic for inclusion here is the presence of a copper-tin alloy as the predominant metallic element.

Distinguishing this category from its sibling, "Of copper-zinc base alloys (brass)," is critical. While both fall under copper alloys in waste and scrap, the defining element here is tin (forming bronze), whereas the sibling specifically identifies zinc as the primary alloying element with copper (forming brass). This distinction is based purely on the chemical composition of the alloy. The "Other" sibling category exists for any remaining copper alloy waste and scrap that does not fit the specific bronze or brass classifications.

As this is a leaf node within the HTS, there are no further subcategories for this specific code. Classification at this level requires a definitive identification of the material as bronze waste and scrap, based on its alloy composition. Importers and exporters must be able to demonstrate through documentation or testing that the waste and scrap material meets the criteria for a copper-tin base alloy.
