Copper; powders of lamellar structure, flakes

HS code 740620 covers the trade of copper powders with a lamellar structure and flakes. This industry plays a crucial role in the broader metal and metal products sector, providing essential raw materials for a wide range of manufacturing and industrial applications. Copper powders and flakes are valued for their unique physical and chemical properties, making them indispensable inputs for various industries, including electronics, automotive, and construction.

The production of copper powders and flakes typically involves mechanical or chemical processes. Mechanical methods, such as milling or atomization, reduce larger copper pieces into fine powders or flakes. Chemical processes, like electrolytic deposition or precipitation, can also be used to produce copper powders with specific particle sizes and morphologies. The choice of production technique depends on the desired characteristics of the final product, such as particle size, purity, and surface area.

The main inputs required for the production of copper powders and flakes include raw copper materials, such as copper scrap or refined copper, as well as specialized machinery and equipment for the milling, atomization, or chemical processing of the copper. Additionally, energy sources, such as electricity or fuel, are necessary to power the production processes.

The primary outputs of HS code 740620 are copper powders and flakes, which are then consumed by various downstream industries. These copper products find applications in 740700 Copper; articles thereof, 853400 Printed circuits, 870120 (Tractors (other than tractors of heading 8709)), and 940600 Prefabricated buildings, among others. The versatility of copper powders and flakes makes them valuable inputs for a wide range of manufacturing and industrial activities.
