Subheadings
Products classified under HTS 7403.29.01
CDA 932 Bearing Bronze Ingot
CDA 932 bearing bronze is a copper-tin alloy containing about 83% copper, 7% tin, and 7% zinc, cast into ingots for further processing. It falls under HTS 7403.29.01 as an unwrought copper-tin base alloy (bronze) that does not meet master alloy specifications. These ingots are melted down to produce bushings and bearings.
Leaded Red Brass C84400 Ingot
Leaded red brass C84400 is a copper alloy with approximately 81% copper, 4% tin, 12% zinc, and 3% lead, supplied as unwrought ingots. Classified under HTS 7403.29.01 as other copper alloys not fitting brass or nickel silver definitions due to tin presence. Used in plumbing fittings and valves.
Aluminum Bronze C95400 Ingot
C95400 aluminum bronze ingot contains 85% copper, 11% aluminum, 4% iron, and 3% nickel in unwrought form. It qualifies under HTS 7403.29.01 as other copper alloys since aluminum predominates over tin or nickel per subheading notes. Ideal for heavy-duty gears and marine propellers.
Silicon Bronze C65500 Ingot
Silicon bronze C65500 consists of 96% copper, 3% silicon, and 1% manganese in pig or ingot form, unwrought. Falls under HTS 7403.29.01 as other copper alloy not matching defined brasses or nickel silvers. Commonly used for weld rods and marine hardware.
Manganese Bronze C86500 Ingot
C86500 manganese bronze ingot is 58% copper, 39% zinc, 2% manganese, and aluminum, cast unwrought. Classified HTS 7403.29.01 as other copper alloy since it doesn't strictly fit brass definitions with multiple elements. Used for propeller shafts and gears.
Naval Brass C46400 Ingot
Naval brass C46400 contains 60% copper, 39% zinc, and 1% tin in unwrought ingot form. HTS 7403.29.01 applies as other copper alloy due to tin addition preventing pure brass classification. Essential for marine hardware and propeller shafts.
Commercial Bronze C22000 Ingot
C22000 commercial bronze is 90% copper and 10% zinc unwrought ingot for architectural applications. Falls under HTS 7403.29.01 as other copper alloy, though low zinc. Used in sheet metal work and decorative trim.
Phosphor Bronze C51000 Ingot
C51000 phosphor bronze contains 94.8% copper, 5% tin, 0.2% phosphorus unwrought. HTS 7403.29.01 classification as other copper-tin alloy (bronze). Precision springs and electrical connectors primary uses.
Cupronickel C70600 Ingot
C70600 cupronickel is 88% copper, 10% nickel, 1% iron, 1% manganese unwrought ingot. Classifies HTS 7403.29.01 as other copper alloy (nickel <5%, zinc absent). Marine condenser tubes and desalination equipment.
High Leaded Tin Bronze C93800 Ingot
C93800 high leaded tin bronze has 78% copper, 15% lead, 7% tin unwrought. HTS 7403.29.01 other copper alloys due to lead dominance preventing standard bronze. Bearings and bushings where lubrication needed.
Yellow Brass C85200 Ingot
C85200 yellow brass contains 62% copper, 34% zinc, 2% lead, 1% tin unwrought. HTS 7403.29.01 as other copper alloy (multi-element). Sand castings for valves and fittings.
Beryllium Copper C17300 Ingot
C17300 beryllium copper has 96% copper, 1.9% beryllium, 0.2% lead unwrought. HTS 7403.29.01 other copper alloys. High strength connectors and springs.
Architectural Bronze C38500 Ingot
C38500 architectural bronze 57% copper, 41% zinc, 2% lead for ornamental work. HTS 7403.29.01 other alloys. Extruded trim and hardware.
Gunmetal LG2 C83600 Ingot
LG2 gunmetal C83600 85% copper, 5% tin, 5% zinc, 5% lead unwrought. HTS 7403.29.01 complex bronze. Valves and fittings.
Everdur Silicon Bronze C87300 Ingot
C87300 Everdur 94% copper, 4% silicon, 1% manganese unwrought. HTS 7403.29.01 other copper alloy. Welding and marine castings.
