Zinc dust

HS v2022 Code: 790310

About zinc dust

HS code 790310 covers zinc dust, a fine metallic powder derived from the processing of zinc ore. Zinc is a versatile and widely-used metal, with applications ranging from galvanization and alloy production to chemical manufacturing and pharmaceuticals. The zinc dust industry plays a crucial role in supplying this essential raw material to various downstream industries, contributing to the broader economic ecosystem.

Production process

Zinc dust is typically produced through the thermal or mechanical processing of zinc metal. In the thermal method, zinc is heated and vaporized, then rapidly cooled to form fine powder particles. Alternatively, the mechanical method involves grinding or milling of zinc ingots or sheets to create the desired dust-like consistency. These production techniques aim to maximize the surface area and reactivity of the zinc particles, making them suitable for a range of industrial applications.

Production inputs

The primary input for the zinc dust industry is zinc metal, which is sourced from mining and smelting operations. Depending on the production method, other key inputs may include specialized equipment such as furnaces, mills, and particle separation systems. Additionally, the industry may rely on energy sources, such as electricity or natural gas, to power the manufacturing processes.

Production outputs

The primary output of the zinc dust industry is, of course, zinc dust itself. This material is then consumed by a variety of downstream industries, including 280700 Zinc oxide and peroxide, 283325 Zinc chloride, and 284690 Other zinc compounds, which utilize zinc dust as a raw material for their own production processes. Zinc dust also finds applications in the manufacture of paints, coatings, and other chemical products.
