Copper; bars, rods and profiles, of copper-zinc base alloys (brass)
HS v2022 Code: 740721
About copper; bars, rods and profiles, of copper-zinc base alloys (brass)
HS code 740721 covers the trade of copper bars, rods, and profiles made from copper-zinc base alloys, commonly known as brass. Brass is a versatile and widely used alloy that combines the strength and corrosion resistance of copper with the affordability and machinability of zinc. This industry plays a crucial role in the manufacturing and construction sectors, providing essential raw materials for a diverse range of applications, from plumbing fixtures to decorative hardware.
Production process
The production of copper-zinc alloy bars, rods, and profiles typically involves a multi-step process. First, the raw materials, including copper and zinc, are melted and alloyed in a furnace. The molten alloy is then cast into ingots or billets, which are subsequently heated and extruded or rolled into the desired shape and size. Precision cutting, drawing, and finishing techniques may be employed to ensure the final products meet the required specifications and tolerances.
Production inputs
The main inputs for the production of HS code 740721 items include refined copper, zinc, and other alloying elements such as lead or tin, depending on the specific brass composition. Additionally, the industry relies on specialized machinery and equipment for melting, casting, extrusion, and finishing processes. Energy sources, such as electricity or natural gas, are also essential for the various manufacturing stages.
Production outputs
The primary outputs of this industry are copper-zinc alloy bars, rods, and profiles, which find applications in a wide range of industries. These products are often used in the manufacture of 731500 plumbing fixtures, 830000 hardware, 871200 bicycle parts, and 940300 furniture components, among others. The versatility of brass makes it a popular choice for both functional and decorative applications across various sectors.
