Zinc; powders and flakes

HS code 790390 covers the trade of zinc powders and flakes, which are essential materials in a wide range of industries. Zinc is a versatile metal with numerous applications, from galvanizing steel to producing brass alloys. The global zinc powder and flakes market is a crucial component of the broader metal and mining industry, playing a vital role in supporting various manufacturing and construction activities worldwide.

Zinc powders and flakes are typically produced through the mechanical processing of zinc metal. This involves techniques such as atomization, where molten zinc is sprayed into a stream of air or inert gas, resulting in the formation of fine zinc particles. Alternatively, zinc can be mechanically ground or milled to create the desired powder or flake form. The specific production methods may vary depending on the desired particle size, shape, and purity requirements of the final product.

The main inputs required for the production of zinc powders and flakes include raw zinc metal, which is typically sourced from zinc mining and smelting operations. Additionally, specialized equipment such as atomizers, mills, and sieves are necessary to transform the zinc into the desired powder or flake form. Energy sources, such as electricity or natural gas, are also essential for the various processing steps involved.

Zinc powders and flakes produced under HS code 790390 find applications in a wide range of industries. They are commonly used as pigments and fillers in paints, coatings, and rubber products. Additionally, zinc powders and flakes are utilized in the production of 740700 Zinc; articles thereof, 282700 Zinc oxide; zinc peroxide, and 283699 Other inorganic compounds n.e.c.; including distilled or conductivity water and water of similar purity, among other related products.
