Copper; wire, of copper-zinc base alloys (brass)

HS v2022 Code: 740821

About copper; wire, of copper-zinc base alloys (brass)

HS code 740821 covers the trade of copper wire made from copper-zinc base alloys, commonly known as brass. Brass is a versatile and widely used alloy that combines the desirable properties of copper and zinc. This industry plays a crucial role in various manufacturing sectors, from construction and plumbing to electrical and automotive applications, making it an integral part of the broader global economy.

Production process

The production of copper wire under HS code 740821 typically involves a multi-step process. First, the copper and zinc are melted and alloyed to create the desired brass composition. The molten alloy is then extruded or drawn through a die to form the wire. Depending on the intended application, the wire may undergo additional processing, such as annealing, coating, or further drawing to achieve the required diameter and properties.

Production inputs

The main inputs for the production of copper wire under HS code 740821 include refined copper, zinc, and various alloying elements. Additionally, specialized machinery, such as wire-drawing equipment and extrusion presses, are essential for the manufacturing process. Energy sources, such as electricity or natural gas, are also required to power the production facilities.

Production outputs

The primary output of this industry is copper wire made from copper-zinc base alloys, which is widely used in a variety of applications. The wire produced under HS code 740821 may be consumed by industries such as 731210 Stranded wire, ropes, cables, 853610 Electrical switches, and 851220 Radiotelephones, among others, as a key component in their manufacturing processes.
