Base metals, silver or gold, clad with platinum; not further worked than semi-manufactured

HS code 711100 covers the classification of base metals, silver, or gold that are clad with platinum and have not been further processed beyond the semi-manufactured stage. This industry plays a crucial role in the global precious metals and jewelry supply chain, providing the raw materials and semi-finished products that are essential for the production of high-end jewelry, decorative items, and various industrial applications.

The production of items under HS code 711100 typically involves a process known as cladding. This technique involves bonding a thin layer of platinum onto the surface of a base metal, silver, or gold substrate. The cladding process can be done through various methods, such as hot or cold rolling, electroplating, or physical vapor deposition. The resulting clad material is then further processed into semi-manufactured forms, such as sheets, strips, or wires, ready for use in downstream industries.

The main inputs required for the production of items under HS code 711100 include the base metals (such as 720810 iron or non-alloy steel, 740311 copper, or 711011 platinum), as well as the necessary machinery and equipment for the cladding and semi-manufacturing processes. Additionally, skilled labor and specialized knowledge in metallurgy and metal processing techniques are essential for this industry.

The primary outputs of the industry covered by HS code 711100 are the semi-manufactured forms of base metals, silver, or gold clad with platinum. These materials are then consumed by various downstream industries, such as 711311 jewelry manufacturing, 711420 other articles of precious metal, and 851440 other electric lamps and lighting fittings, where they are further processed into finished products.
