Zinc; dust, powders and flakes

HS v2017 Code: 7903

About zinc; dust, powders and flakes

hs code 7903 covers the classification of zinc in the form of dust, powders, and flakes. Zinc is a versatile and essential metal with a wide range of industrial applications, making it a crucial component in the global economy. This classification encompasses the various physical forms of zinc that are produced and traded internationally, serving as raw materials for numerous downstream industries.

Production process

Zinc dust, powders, and flakes are typically produced through the smelting and refining of zinc ore. The ore is first crushed and concentrated, then subjected to high-temperature smelting processes to extract the pure zinc metal. The molten zinc is then further refined and transformed into the desired physical forms, such as dust, powders, or flakes, through specialized mechanical and thermal treatments.

Production inputs

The production of zinc dust, powders, and flakes requires several key inputs, including zinc ore, energy sources for smelting and refining, and specialized equipment for the mechanical processing and shaping of the final products. Additionally, the industry relies on a robust supply chain of logistics and transportation services to facilitate the movement of raw materials and finished goods across global markets.

Production outputs

Zinc dust, powders, and flakes classified under hs code 7903 are widely used as raw materials in various industries, including 7907 Zinc articles, n.e.s., 8108 Titanium and articles thereof, and 8110 Antimony and articles thereof. These zinc products serve as essential components in the production of galvanized steel, brass alloys, and a range of other metal-based products and applications.
