Aluminium; powders and flakes

HS v2022 Code: 7603

About aluminium; powders and flakes

HS code 7603 covers the classification of aluminium powders and flakes, which are essential materials in a wide range of industries. Aluminium, being a lightweight, durable, and corrosion-resistant metal, has become a crucial component in various manufacturing processes, from automotive and aerospace to construction and electronics. The global demand for aluminium powders and flakes continues to grow, driven by the increasing need for lightweight and energy-efficient products across diverse sectors.

Production process

Aluminium powders and flakes are typically produced through mechanical or chemical processes. Mechanical methods involve grinding or milling solid aluminium into fine particles, while chemical processes may involve the reduction of aluminium salts or the atomization of molten aluminium. The specific production techniques used depend on the desired particle size, shape, and purity of the final product.

Production inputs

The main inputs required for the production of aluminium powders and flakes include raw aluminium, milling or grinding equipment, and various chemical reagents (depending on the production method). Additionally, energy sources, such as electricity or fuel, are necessary to power the manufacturing processes. The availability and cost of these inputs can significantly impact the overall production and pricing of aluminium powders and flakes.

Production outputs

The primary outputs of HS code 7603 are aluminium powders and flakes, which find applications in a wide range of industries. These materials are commonly used in the production of 7608 Aluminium tubes and pipes, 7609 Aluminium tube or pipe fittings, and 7610 Aluminium structures and parts of structures. Additionally, aluminium powders and flakes are utilized in the manufacture of paints, coatings, explosives, and various other products that require lightweight, conductive, or decorative materials.
