Copper; refined, unwrought, wire-bars

HS v2017 Code: 740312

About copper; refined, unwrought, wire-bars

HS code 740312 covers refined, unwrought copper in the form of wire-bars. Copper is a highly versatile and essential metal, widely used in a variety of industries due to its excellent electrical and thermal conductivity, corrosion resistance, and malleability. The copper wire-bars industry plays a crucial role in the global supply chain, providing a vital raw material for the manufacturing of electrical wiring, plumbing, and a wide range of other copper-based products.

Production process

The production of refined, unwrought copper wire-bars typically involves a multi-step process. First, copper ore is extracted from mines and then undergoes smelting and refining to remove impurities and produce pure copper. The refined copper is then cast into wire-bars, which are long, cylindrical shapes that can be easily transported and further processed into various copper products.

Production inputs

The main inputs required for the production of copper wire-bars include copper ore, energy sources (such as electricity or natural gas) for smelting and refining, and specialized equipment like furnaces, casting molds, and rolling mills. Additionally, the industry relies on a skilled workforce with expertise in metallurgy and metal processing techniques.

Production outputs

Copper wire-bars produced under HS code 740312 are a crucial input for a wide range of industries, including 854411 Winding wire, 741010 Copper foil, and 732111 Cooking appliances. These wire-bars can be further processed into various copper products, such as electrical wiring, plumbing pipes, and components for electronic devices.
