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 economy, supporting industries that rely on its unique properties and cost-effectiveness.

Unwrought zinc is primarily produced through the smelting of zinc ore, a process that involves the extraction, concentration, and reduction of zinc-containing minerals. The most common method is the electrolytic process, where zinc ore is first roasted and then leached to produce a zinc sulfate solution, which is subsequently purified and electrolyzed to yield high-purity zinc metal.

The production of unwrought zinc requires several key inputs, including zinc-bearing ores, such as sphalerite and smithsonite, as well as various energy sources, such as electricity and natural gas, to power the smelting and refining processes. Additionally, the industry relies on specialized equipment, including furnaces, electrolytic cells, and casting machinery, to efficiently transform the raw materials into the final unwrought zinc product.

Unwrought zinc produced under HS code 7901 is a versatile material that finds application in a wide range of industries. It is a key input for the production of 7907 Other articles of zinc, 7907 Zinc alloys, and 7310 (Tanks, casks, drums, cans, boxes and similar containers, of iron or steel, for any material (other than compressed or liquefied gas)), among others. The zinc industry also supports the production of 8108 Titanium and articles thereof, 8501 Electric motors and generators, and 8507 (Electric accumulators, including separators therefor, whether or not rectangular (including square)), where zinc is used as a protective coating or alloying element.
