Copper; refined, unwrought, billets

HS v2022 Code: 740313

About copper; refined, unwrought, billets

HS code 740313 covers refined, unwrought copper billets. Copper is a highly versatile and essential metal with a wide range of industrial and commercial applications. As a key input for electrical wiring, plumbing, and various manufacturing processes, the refined copper industry plays a crucial role in supporting the broader economy. This code represents a vital stage in the copper supply chain, transforming raw copper into a refined, semi-finished product ready for further processing and fabrication.

Production process

The production of refined copper billets typically involves several key steps. First, raw copper ore is extracted and processed through smelting and refining techniques to produce pure, unalloyed copper. This refined copper is then cast into billets, which are long, cylindrical semi-finished products. The casting process involves pouring the molten copper into molds, where it solidifies into the desired billet shape and size.

Production inputs

The main inputs required for the production of refined copper billets include raw copper ore, as well as energy sources, such as electricity or natural gas, to power the smelting, refining, and casting processes. Specialized equipment, such as furnaces, casting molds, and rolling mills, are also essential for the efficient transformation of raw copper into the refined billet form.

Production outputs

Refined copper billets produced under HS code 740313 are a key input for a wide range of downstream industries. These billets may be further processed through drawing, rolling, or extrusion to create copper wire, sheets, tubes, and other semi-finished copper products 740811 Copper; wire, refined, 740921 Copper; plates, sheets and strip, of a thickness exceeding 0.15 mm, and 741110 Copper; tubes and pipes. These refined copper products are then utilized in a diverse array of applications, including electrical wiring, plumbing, construction, and various manufacturing sectors.
