Products classified under HTS 7403.21.00.00
C26000 Cartridge Brass Ingot
C26000 cartridge brass is a copper-zinc base alloy containing approximately 30% zinc, cast into ingot form for further processing. It falls under HTS 7403.21.00.00 as unwrought brass meeting the definition of copper-zinc base alloys where zinc predominates over other elements. Commonly used for ammunition casings and architectural applications.
C36000 Free-Cutting Brass Billet
C36000 free-cutting brass billet is an unwrought copper-zinc alloy with added lead for machinability, containing 60% copper and 36% zinc. Classified under HTS 7403.21.00.00 as brass since zinc predominates over other elements and lead is permitted. Used primarily for screw machine products and fittings.
C46400 Naval Brass Slab
C46400 naval brass slab is an unwrought form of copper-zinc-tin alloy with 1% tin maximum, maintaining brass classification. Meets HTS 7403.21.00.00 criteria as zinc predominates over tin (<3%). Ideal for marine hardware and propeller shafts.
C37700 Forging Brass Ingot
C37700 forging brass ingot is unwrought copper-zinc-lead alloy designed for hot forging applications. Classified as brass under HTS 7403.21.00.00 with zinc as predominant alloying element. Used for valves, fittings, and plumbing components.
C69300 Arsenical Brass Billet
C69300 arsenical brass billet contains small amounts of arsenic for improved corrosion resistance in copper-zinc matrix. Remains classified as brass under HTS 7403.21.00.00 since zinc predominates and other elements are minor. Used for condenser tubes.
C35300 High-Leaded Brass Slab
C35300 high-leaded brass slab offers excellent machinability from 2-3% lead in copper-zinc base. HTS 7403.21.00.00 classification confirmed by zinc predominance over lead. Used for precision screw machine parts.
C87200 Silicon Brass Ingot
C87200 silicon brass ingot incorporates 4% silicon into copper-zinc matrix for casting applications. Still qualifies as brass under HTS 7403.21.00.00 with zinc predominant. Used for valve stems and marine castings.
C67000 Manganese Brass Billet
C67000 manganese brass billet adds manganese for strength in copper-zinc base alloy. Meets HTS 7403.21.00.00 brass definition with zinc predominance. Hot forge applications for structural components.
C69400 Copper-Base Casting Brass Ingot
C69400 casting brass ingot optimized for sand casting with copper-zinc-lead-aluminum composition. Classified HTS 7403.21.00.00 as zinc-predominant brass alloy. Used for marine castings and pump components.
C83600 Commercial 85-5-5-5 Brass Ingot
C83600 (85-5-5-5) commercial brass ingot contains 85% Cu, 5% Zn, 5% Sn, 5% Pb but zinc/tin equivalent maintains brass status. HTS 7403.21.00.00 as copper-zinc base per legal definitions. Standard sand casting alloy.
