HS Code 79031000: Zinc Dust

Zinc dust, classified under HS Code 79031000, is a powdered form of zinc that is commonly used in various industries due to its unique properties. This article will provide an extensive overview of this product, its uses, and relevant information related to its import and export.

Product Description

Zinc dust is a fine powder consisting of zinc particles. It is produced by vaporizing zinc and condensing the vapor into solid particles. The resulting powder has a grayish appearance and is highly reactive due to the large surface area of the particles. This reactivity makes zinc dust suitable for various applications.

Uses of Zinc Dust

Zinc dust finds applications in several industries due to its unique properties. Some of the major uses of zinc dust include:

• Corrosion Protection: Zinc dust is widely used as a corrosion inhibitor in coatings and paints. It creates a protective barrier on the surface, preventing the underlying metal from corroding.
• Galvanizing: Zinc dust is an essential component in the galvanizing process, where it is used to coat steel or iron surfaces to protect them from rust and corrosion.
• Chemical Reactions: Zinc dust is utilized in various chemical reactions, such as the production of chemicals like zinc oxide, zinc cyanide, and zinc chloride.
• Batteries: Zinc dust is a key ingredient in the production of zinc-carbon batteries, commonly used in household devices like remotes and flashlights.
• Pyrotechnics: Due to its combustible nature, zinc dust is employed in the production of fireworks and other pyrotechnic devices.
