Copper; refined, unwrought, wire-bars

HS v2022 Code: 740312

About copper; refined, unwrought, wire-bars

HS code 740312 covers refined, unwrought copper in the form of wire-bars. Copper is a vital industrial metal with a wide range of applications across various sectors, including construction, electronics, and transportation. As a highly conductive and corrosion-resistant material, refined copper is an essential component in the production of electrical wiring, plumbing, and a multitude of other products that underpin modern infrastructure and technology.

Production process

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

Production inputs

The main inputs required for the production of refined 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 manufacturing processes.

Production outputs

Refined copper wire-bars produced under HS code 740312 are a crucial input for a wide range of downstream industries. These include the manufacture of 740811 Copper; wire, of refined copper, 741110 Copper; tubes and pipes, and 850710 Electric accumulators; lead-acid, of a kind used for starting piston engines, among others. The versatility of refined copper makes it an essential material for the production of electrical components, plumbing systems, and a variety of other products that are vital to modern economies.
