Phosphor Bronze Scrap Turnings
Machining turnings and chips from phosphor bronze, a copper-tin base alloy containing 5-10% tin with phosphorus addition, collected from precision manufacturing. Classified under HTS 7404.00.30.65 as waste and scrap of copper-tin base alloys (bronze) with copper content under 94% by weight due to impurities and alloying elements. Typically low-value scrap destined for remelting in bronze production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nickel content exceeds 5% by weight
Becomes copper-nickel-zinc base alloy (nickel silver) per subheading note (c), shifting to nickel silver scrap category.
If zinc predominates over other elements besides copper
Qualifies as copper-zinc base alloy (brass) under note (a) rather than bronze if zinc > tin and meets brass criteria.
If refined to ≥94% copper content
Exceeds the <94% copper threshold for alloy scrap, moving to high-copper waste category.

Import Tips & Compliance
• Obtain chemical assay certificates verifying tin predominance and copper <94%; declare exact alloy composition per subheading note (b); watch for contamination with lead/iron triggering reclassification
