Zinc; dust, powders and flakes

HS v2022 Code: 7903

About zinc; dust, powders and flakes

HS code 7903 covers zinc in the form of dust, powders, and flakes. 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 crucial role in supporting construction, automotive, and other manufacturing sectors.

Production process

The production of zinc dust, powders, and flakes typically involves the thermal or electrolytic extraction of zinc from its ore. The raw zinc material is then subjected to various mechanical processes, such as milling, sieving, and classification, to produce the desired particle size and shape distributions. Advanced techniques like atomization may also be employed to create fine, uniform zinc powders.

Production inputs

The primary inputs for the zinc dust, powders, and flakes industry include zinc ore, energy sources (e.g., electricity, natural gas), and specialized production equipment such as mills, sieves, and atomizers. Additionally, the industry relies on a skilled workforce capable of operating and maintaining the production machinery.

Production outputs

The main outputs of the zinc dust, powders, and flakes industry are the various forms of refined zinc products, which are then consumed by a wide range of downstream industries. These include the production of 7907 Zinc; other articles, 7907 Zinc; other articles, and 8108 Titanium; articles thereof, including waste and scrap, among others. The versatility of zinc in applications such as galvanization, alloying, and chemical production ensures a steady demand for these zinc-based materials.
