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 workability of zinc. This industry plays a crucial role in the global manufacturing and construction sectors, providing essential raw materials for a wide range of applications.

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 hot-rolled or extruded into the desired shapes and sizes. Finally, the products may undergo additional finishing processes, such as drawing, straightening, or surface treatment, to meet specific customer requirements.

The main inputs for the production of HS code 740721 products are copper and zinc, which are the primary raw materials. Additionally, the industry relies on specialized machinery and equipment for melting, casting, rolling, and extrusion processes. Energy sources, such as electricity or natural gas, are also essential for the various production stages. Skilled labor, including metallurgists, engineers, and technicians, is another critical input for this industry.

The primary outputs of HS code 740721 are copper-zinc alloy bars, rods, and profiles, which are used in a wide range of applications. These products are often consumed by industries such as 731500 Copper wire, cable, and related products, 732111 Stoves and ranges, and 732190 Parts for stoves, ranges, and similar non-electric domestic appliances. The versatility of brass allows it to be used in plumbing, electrical, automotive, and construction applications, among others.
