Copper; powders and flakes

HS v2017 Code: 7406

About copper; powders and flakes

HS code 7406 covers copper powders and flakes, which are essential raw materials for a wide range of industries. Copper is a highly conductive and malleable metal, making it a crucial component in electrical, electronics, and construction applications. The copper powders and flakes industry plays a vital role in supporting the global economy by providing essential inputs for manufacturing, infrastructure development, and technological innovation.

Production process

Copper powders and flakes are typically produced through mechanical or chemical processes. Mechanical methods involve grinding or atomizing copper into fine particles, while chemical processes may involve the reduction of copper salts or the decomposition of copper compounds. These production techniques aim to create copper powders and flakes with specific particle sizes, shapes, and purity levels to meet the diverse requirements of various industries.

Production inputs

The production of copper powders and flakes requires several key inputs, including high-purity copper as the primary raw material, as well as specialized machinery and equipment for grinding, atomizing, or chemical processing. Additionally, energy sources, such as electricity or fuel, and various chemicals or reagents may be necessary, depending on the specific production methods employed.

Production outputs

The copper powders and flakes produced under HS code 7406 are used as inputs for a wide range of industries, including 7413 Stranded wire, cables, plaited bands and the like, of copper, not electrically insulated, 8504 (Electrical transformers, static converters (for example, rectifiers) and inductors), and 8517 (Telephone sets, including telephones for cellular networks or for other wireless networks; other apparatus for the transmission or reception of voice, images or other data, including apparatus for communication in a wired or wireless network (such as a local or wide area network), other than transmission or reception apparatus of heading 8443, 8525, 8527 or 8528).
