Zinc; powders and flakes

hs code 790390 covers the classification of zinc powders and flakes. Zinc is a versatile metal with a wide range of industrial applications, making it an important commodity in the global economy. The zinc powder and flake industry plays a crucial role in supplying raw materials for various manufacturing processes, from galvanization to the production of brass and other zinc-based alloys.

Zinc powders and flakes are typically produced through mechanical processes, such as atomization or milling. In the atomization process, molten zinc is forced through small orifices, creating fine droplets that solidify into powder particles. Milling involves grinding solid zinc into smaller flakes or powders using specialized equipment. The specific production techniques may vary depending on the desired particle size, shape, and purity requirements of the final product.

The main inputs for the zinc powder and flake industry include raw zinc metal, as well as energy sources and specialized equipment for the production processes. Zinc ore, which is mined and refined, is the primary raw material. Additionally, the industry relies on machinery and tools for melting, atomizing, and milling the zinc into the desired forms.

The primary outputs of the zinc powder and flake industry are the various grades and forms of zinc powders and flakes. These products are then used as inputs for a wide range of industries, including 790700 Zinc dust, powders, and flakes, 790310 Zinc; unwrought, and 790320 Zinc; waste and scrap, as well as in the production of brass, galvanized steel, and other zinc-based alloys and compounds.
