HS v2022 Code: 7402

About copper; unrefined, copper anodes for electrolytic refining

HS code 7402 covers unrefined copper and copper anodes used in the electrolytic refining process. This industry is a critical component of the global metals and mining sector, providing the raw material for a wide range of downstream applications. Copper is an essential conductor of electricity and heat, making it indispensable for industries such as construction, electronics, and transportation. The production and trade of unrefined copper plays a significant role in the international economy.

Production process

The production of unrefined copper, as described by HS code 7402, primarily involves the smelting and refining of copper ore. The ore is first extracted from mines, then crushed and concentrated to increase the copper content. The concentrated ore is then smelted in a furnace, where impurities are removed, and the molten copper is cast into anodes. These copper anodes are then used in the electrolytic refining process, where they are dissolved and the pure copper is deposited onto a cathode.

Production inputs

The main inputs required for the production of unrefined copper and copper anodes include copper ore, energy sources (such as coal or natural gas) for smelting, and specialized equipment like furnaces, casting molds, and electrolytic cells. Additionally, the industry relies on a skilled workforce, transportation infrastructure, and access to international markets to facilitate the trade of these products.

Production outputs

The primary output of HS code 7402 is unrefined copper and copper anodes, which are then used as inputs for the production of 7403 Copper; refined, and copper alloys, unwrought, 7404 Copper waste and scrap, and other downstream copper-based products. These refined copper and copper alloy products are essential for a wide range of industries, including 8501 Electric motors and generators, 8517 Telephone sets, including telephones for cellular networks or for other wireless networks, and 8544 Insulated wire, cable and other insulated electric conductors, among others.
