Zinc; waste and scrap

HS code 790200 covers the trade of zinc, including both refined zinc and zinc waste and scrap. Zinc is a versatile metal with a wide range of industrial applications, making it an important commodity in the global economy. As a key component in the production of galvanized steel, brass, and various alloys, the zinc industry plays a vital role in supporting the manufacturing and construction sectors worldwide.

The primary production technique for refined zinc involves the pyrometallurgical or hydrometallurgical processing of zinc-containing ores and concentrates. This typically includes roasting, leaching, and electrolytic or thermal smelting to extract and purify the zinc metal. Zinc waste and scrap, on the other hand, is often recycled through remelting and refining processes to recover the valuable zinc content.

The main inputs required for the zinc industry include zinc-bearing ores and concentrates, as well as various energy sources, such as coal or natural gas, to power the smelting and refining processes. Additionally, the industry relies on specialized equipment and machinery, including furnaces, electrolytic cells, and other processing equipment.

The primary outputs of the zinc industry are refined zinc metal and zinc alloys, which are then used in a wide range of applications, including 721010 galvanized steel, 740110 brass, and various die-cast products. The zinc waste and scrap generated during production and manufacturing processes can also be recycled and reused, contributing to the overall sustainability of the industry.
