7404.00.60.45 - Containing more than 0.3 percent of lead

This HTS category, 7404.00.60.45, specifically classifies copper-zinc base alloy (brass) waste and scrap that contains more than 0.3 percent lead. This distinction is crucial for customs purposes, as the lead content often dictates specific import or export duties, environmental regulations, or handling requirements. Examples of items falling under this classification include discarded brass components from manufacturing, old brass plumbing fixtures, or brass turnings from machining operations, provided they meet the lead percentage threshold.

It's important to differentiate this category from its sibling, 7404.00.60.55, which covers "Other" copper-zinc base alloy waste and scrap. The defining characteristic for 7404.00.60.45 is the presence of lead exceeding 0.3 percent. Therefore, any brass scrap with a lower lead content would be classified under the "Other" category. The classification hinges on the precise chemical composition of the alloy, requiring accurate material analysis to ensure correct declaration.

As this is a leaf node within the HTS structure, there are no further subcategories. All brass waste and scrap meeting the specified lead content criteria will be classified here. The focus for classification under this heading is therefore on the material composition and the fact that the material is in a "waste or scrap" form, indicating it is intended for reprocessing or remelting rather than direct use.
