About zinc; unwrought, (not alloyed), containing by weight less than 99.99% of zinc

HS code 790112 covers the import and export of unwrought zinc, not alloyed, containing less than 99.99% zinc by weight. Zinc is a versatile metal with a wide range of industrial applications, making it an important commodity in the global trade of raw materials. This code is particularly significant as it encompasses the trade of a key base metal that is essential for various manufacturing processes and infrastructure development across numerous sectors.

Production process

Zinc is primarily produced through the pyrometallurgical or hydrometallurgical processing of zinc-containing ores. The pyrometallurgical process involves roasting the ore, reducing the zinc oxide to molten zinc, and then refining the metal. The hydrometallurgical process, on the other hand, uses leaching, solvent extraction, and electrowinning to extract and purify the zinc. Both methods aim to produce high-purity zinc metal that meets the specifications outlined in HS code 790112.

Production inputs

The main inputs required for the production of zinc under HS code 790112 include zinc-containing ores, such as sphalerite and smithsonite, 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, such as furnaces, electrolytic cells, and refining tanks, to extract and purify the zinc metal.

Production outputs

The primary output of HS code 790112 is unwrought zinc with a purity of less than 99.99% by weight. This zinc metal is then used as a raw material in a wide range of industries, including 780110 (Zinc; unwrought, (not alloyed), containing by weight 99.99% or more of zinc), 780120 (Zinc; unwrought, (not alloyed), containing by weight less than 99.99% of zinc), and 282700 Zinc oxide; zinc peroxide, among others. The zinc produced under this code is essential for the manufacture of galvanized steel, brass, and various zinc-based alloys, as well as for use in the production of chemicals, batteries, and other industrial applications.
