Products classified under Tariff item 7403.21
C26000 Cartridge Brass Ingot
C26000 cartridge brass ingot is an unwrought copper-zinc base alloy containing approximately 30% zinc, cast into ingot form for further processing. It qualifies as a copper-zinc base alloy (brass) under tariff item 7403.21.00 because zinc is the predominant alloying element after copper, and the alloy meets the definition of brass in the chapter notes.
7403.21.00C35300 High-Leaded Brass Slab
C35300 high-leaded brass slab is an unwrought copper-zinc base alloy containing approximately 60% copper, 36% zinc, and 2-3% lead. It falls under tariff item 7403.21.00 as a copper-zinc base alloy (brass) because zinc predominates over lead and other elements, and the lead content is within the limits that still allow classification as brass.
7403.21.00C36000 Free-Cutting Brass Billet
C36000 free-cutting brass billet is an unwrought copper-zinc base alloy containing approximately 60% copper, 36% zinc, and 3% lead. It is classified under tariff item 7403.21.00 as a copper-zinc base alloy (brass) because zinc is the predominant alloying element after copper, and the lead content does not disqualify it from brass classification.
7403.21.00C37700 Forging Brass Ingot
C37700 forging brass ingot is an unwrought copper-zinc-lead alloy designed for hot forging applications. It contains approximately 60% copper, 38% zinc, and 2% lead, with zinc predominating over lead and other elements. It qualifies as a copper-zinc base alloy (brass) under tariff item 7403.21.00.
7403.21.00C46400 Naval Brass Slab
C46400 naval brass slab is an unwrought copper-zinc-tin alloy containing approximately 60% copper, 39% zinc, and 1% tin. It is classified under tariff item 7403.21.00 as a copper-zinc base alloy (brass) because zinc predominates over tin, and the tin content is less than 3%, which keeps it within the brass definition.
7403.21.00C67000 Manganese Brass Billet
C67000 manganese brass billet is an unwrought copper-zinc base alloy with manganese added for strength. It contains approximately 63% copper, 30% zinc, and 5% manganese, with zinc predominating over manganese and other elements. It qualifies as a copper-zinc base alloy (brass) under tariff item 7403.21.00.
7403.21.00C69300 Arsenical Brass Billet
C69300 arsenical brass billet is an unwrought copper-zinc base alloy containing small amounts of arsenic for improved corrosion resistance. It contains approximately 60% copper, 39% zinc, and 0.1% arsenic, with zinc predominating over arsenic. It is classified under tariff item 7403.21.00 as a copper-zinc base alloy (brass).
7403.21.00C69400 Copper-Base Casting Brass Ingot
C69400 casting brass ingot is an unwrought copper-zinc-lead-aluminum alloy optimized for sand casting. It contains approximately 60% copper, 35% zinc, 3% lead, and 1% aluminum, with zinc predominating over lead and aluminum. It qualifies as a copper-zinc base alloy (brass) under tariff item 7403.21.00.
7403.21.00C83600 Commercial 85-5-5-5 Brass Ingot
C83600 commercial 85-5-5-5 brass ingot contains approximately 85% copper, 5% zinc, 5% tin, and 5% lead. It is classified under tariff item 7403.21.00 as a copper-zinc base alloy (brass) because the zinc content, while not the highest alloying element, is within the brass definition when considering the tin and lead content together.
7403.21.00C87200 Silicon Brass Ingot
C87200 silicon brass ingot is an unwrought copper-zinc base alloy containing approximately 60% copper, 36% zinc, and 4% silicon. It is classified under tariff item 7403.21.00 as a copper-zinc base alloy (brass) because zinc predominates over silicon, and the alloy meets the brass definition in the chapter notes.
