HS v2022 Code: 7901

About zinc; unwrought

HS code 7901 covers the trade of unwrought zinc, a versatile non-ferrous metal with a wide range of industrial applications. Zinc is an essential component in the production of galvanized steel, brass, and various alloys, making it a crucial material for the construction, automotive, and manufacturing sectors. As a global commodity, the trade of unwrought zinc plays a significant role in the broader international economy.

Production process

Unwrought zinc is primarily produced through the smelting of zinc-containing ores, such as sphalerite and smithsonite. The ore is first concentrated through a process of crushing, grinding, and flotation, then reduced in a high-temperature furnace to extract the pure zinc metal. Electrolytic refining may also be used to further purify the zinc, resulting in a high-quality product suitable for a variety of applications.

Production inputs

The production of unwrought zinc requires several key inputs, including zinc-bearing ores, reducing agents such as coal or coke, and significant amounts of energy to power the smelting and refining processes. Specialized equipment, such as furnaces, electrolytic cells, and casting machinery, are also essential for the efficient and large-scale production of unwrought zinc.

Production outputs

Unwrought zinc produced under HS code 7901 is a versatile material that serves as a key input for a wide range of downstream industries. It is commonly used in the production of 7907 Other articles of zinc, 8108 Titanium and articles thereof, and 8501 Electric motors and generators, among others. The zinc industry's outputs are essential for the manufacturing of galvanized steel, brass, and various alloys, which are vital components in the construction, automotive, and consumer goods sectors.
