Metals; silver powder

HS code 710610 covers the classification of silver powder, a valuable and versatile material with a wide range of industrial applications. Silver powder is an essential component in various manufacturing processes, from electronics and jewelry to catalysts and medical devices. Its unique properties, such as high electrical and thermal conductivity, make it a crucial material in the global economy, particularly in the electronics and automotive industries.

Silver powder is typically produced through a process called atomization. In this method, molten silver is forced through a small orifice and broken up into fine droplets by a high-pressure gas stream. The droplets then solidify into small, spherical particles of silver powder. The size and shape of the powder can be controlled by adjusting the process parameters, such as the temperature, pressure, and gas flow rate.

The production of silver powder requires several key inputs, including high-purity silver as the primary raw material, as well as specialized equipment such as atomization chambers, gas supply systems, and powder handling and storage facilities. Additionally, the process may require the use of inert gases, such as nitrogen or argon, to create the necessary environment for the atomization and solidification of the silver.

Silver powder produced under HS code 710610 is a versatile material with a wide range of applications. It is commonly used in the manufacture of 851780 Electrical apparatus for line telephony or line telegraphy, 851762 Machines for the reception, conversion and transmission or regeneration of voice, images or other data, including switching and routing apparatus, and 854411 (Insulated (including enamelled or anodised) wire, cable (including co-axial cable) and other insulated electric conductors, whether or not fitted with connectors; optical fibre cables), where its high conductivity and small particle size make it an ideal material for conductive coatings and inks. Silver powder is also used in the production of 711311 Articles of jewelry and parts thereof, of silver, whether or not plated or clad with other precious metal and 711590 Other articles of precious metal or of metal clad with precious metal, as well as in various catalytic applications.
