About colloidal precious metals; inorganic or organic compounds of precious metals, whether or not chemically defined; amalgams of precious metals

HS code 2843 covers a diverse range of precious metal products, including colloidal precious metals, inorganic and organic compounds of precious metals, and amalgams of precious metals. These materials play a crucial role in various industries, from electronics and catalysts to pharmaceuticals and jewelry. As precious metals are scarce and valuable, the 2843 industry is an important part of the global economy, facilitating the production and trade of essential materials.

Production process

The production of goods under HS code 2843 typically involves complex chemical processes. Colloidal precious metals are often created through reduction of precious metal salts, while inorganic and organic compounds may be synthesized through reactions between precious metals and other elements or compounds. Amalgams, which are alloys of precious metals, are formed by combining the metals under specific conditions. Advanced techniques like electroplating and vapor deposition may also be employed to create specialized precious metal products.

Production inputs

The main inputs required for the 2843 industry include precious metal raw materials such as 7106 Silver, 7110 Platinum, and 7108 Gold. Depending on the specific product, other chemical reagents, solvents, and specialized equipment like reaction vessels and purification systems may also be necessary. Skilled labor, including chemists and process engineers, is crucial for the safe and efficient production of these sensitive materials.

Production outputs

The outputs of the 2843 industry are diverse, ranging from colloidal precious metals used in catalysts and electronics to inorganic and organic compounds employed in pharmaceuticals and photography. The products of this industry are often intermediary materials that are further processed or incorporated into a wide variety of final goods, including 8517 Telephone sets, including telephones for cellular networks or for other wireless networks, 9018 Instruments and appliances used in medical, surgical, dental or veterinary sciences, and 7113 Articles of jewelry and parts thereof, of precious metal or of metal clad with precious metal.
