Products classified under HTS 7404.00.30.65
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.
Aluminum Bronze Bushing Scrap
Worn-out industrial bushings and bearings made from aluminum bronze (Cu-10%Sn-5-11%Al), scrapped from heavy machinery. Falls under HTS 7404.00.30.65 as tin-base bronze scrap (<94% Cu) where tin predominates over aluminum per subheading note (b). Common in automotive and marine applications before recycling.
Tin Bronze Valve Scrap
Discarded ship and industrial valves cast from UNS C83600 tin bronze (88%Cu-10%Sn-2%Zn). HTS 7404.00.30.65 applies as copper-tin base alloy scrap with <94% copper due to tin/impurities. Recycled for new castings in plumbing and marine sectors.
Leaded Tin Bronze Rod Ends Scrap
Machined rod ends from leaded tin bronze (Cu-10%Sn-5%Pb) used in connectors, scrapped from aerospace/automotive production. Under HTS 7404.00.30.65 as bronze scrap (<94%Cu) with tin-base alloy per note (b); lead is permitted minor element.
Silicon Bronze Welding Rod Scrap
Used/overrun welding rods of silicon bronze (Cu-5%Sn-3%Si), generated from fabrication shops. HTS 7404.00.30.65 covers this tin-base bronze scrap (<94%Cu) where tin > silicon per definition (b).
Gunmetal Bearing Scrap
Scrap bearings from gunmetal (LG2 bronze: 88%Cu-10%Sn-2%Zn), traditional marine propeller alloy. Classified HTS 7404.00.30.65 as tin-bronze waste (<94%Cu); zinc minor per note (b).
Bell Bronze Casting Runners
Gate and riser scrap from bell bronze castings (78%Cu-20-22%Sn), used for musical instruments. HTS 7404.00.30.65 as high-tin bronze scrap (<94%Cu), tin clearly predominates.
