About base metals clad with silver; not further worked than semi-manufactured

HS code 7107 covers the classification of base metals clad with silver, which are not further worked than semi-manufactured. This industry plays a crucial role in the global precious metals trade, providing a cost-effective alternative to solid silver products. The production and trade of these semi-manufactured base metal-silver composites are integral to various industries, including jewelry, silverware, and electronics manufacturing.

Production process

The primary production technique for base metals clad with silver involves metallurgical bonding processes. This typically involves cladding a base metal, such as copper or nickel, with a thin layer of silver through methods like roll bonding, electroplating, or hot dip coating. The resulting composite material is then shaped and processed into various semi-manufactured forms, such as sheets, strips, or wires, ready for further fabrication or assembly.

Production inputs

The main inputs required for the production of base metals clad with silver include the base metal (e.g., copper, nickel) and silver. Specialized machinery and equipment, such as rolling mills, cladding machines, and cutting tools, are also essential for the manufacturing process. Additionally, skilled labor and technical expertise in metallurgy and metal processing are necessary to ensure the quality and consistency of the final products.

Production outputs

The primary outputs of HS code 7107 are semi-manufactured base metal-silver composite materials, which can be further processed and fabricated into a wide range of products. These outputs may be consumed by industries such as 7113 Articles of jewelry and parts thereof, of precious metal or of metal clad with precious metal, 7114 Articles of goldsmiths' or silversmiths' wares and parts thereof, of precious metal or of metal clad with precious metal, and 8517 Electrical apparatus for line telephony or line telegraphy, including line telephone sets with cordless handsets and telecommunication apparatus for carrier-current line systems or for digital line systems, among others.
