Copper mattes; cement copper (precipitated copper)

HS v2022 Code: 7401

About copper mattes; cement copper (precipitated copper)

HS code 7401 covers copper mattes and cement copper, which are important intermediate products in the copper production industry. Copper is a vital metal for a wide range of applications, from electrical wiring and electronics to construction and transportation. The copper industry plays a crucial role in the global economy, supporting various downstream industries and contributing to economic development worldwide.

Production process

Copper mattes are produced by smelting copper ore, which involves heating the ore to high temperatures to extract the copper. The resulting copper matte is then further refined to produce pure copper. Cement copper, on the other hand, is produced through a chemical process where copper ions in a solution are precipitated onto a surface, forming a copper deposit.

Production inputs

The production of copper mattes and cement copper requires several key inputs, including copper ore, reducing agents (such as coal or coke), and various chemicals for the precipitation process. Additionally, specialized equipment, such as smelters, furnaces, and reactors, are essential for the different stages of production.

Production outputs

The primary outputs of HS code 7401 are copper mattes and cement copper, which are then further processed to produce refined copper 7403 Copper and copper alloys, unwrought. These refined copper products are used in a wide range of industries, including 8501 Electric motors and generators, 8536 Electrical apparatus for switching or protecting electrical circuits, and 7604 Aluminium bars, rods and profiles.
