Copper; plates and sheets, of a thickness exceeding 0.15mm, of copper-tin base alloys, not in coils

HS v2017 Code: 740939

About copper; plates and sheets, of a thickness exceeding 0.15mm, of copper-tin base alloys, not in coils

HS code 740939 covers copper plates and sheets that are thicker than 0.15mm and made from copper-tin base alloys. These materials are widely used in a variety of industries, including construction, electrical engineering, and transportation. They offer a unique combination of strength, corrosion resistance, and thermal conductivity, making them essential components in many industrial applications.

Production process

The production of copper plates and sheets under HS code 740939 typically involves a multi-step process. First, the copper-tin alloy is melted and cast into ingots or billets. These are then subjected to hot or cold rolling to reduce the thickness and achieve the desired dimensions. The rolled sheets may undergo additional processing, such as annealing or surface finishing, to enhance their properties and appearance.

Production inputs

The main inputs required for the production of HS code 740939 products include copper and tin as the primary raw materials. Specialized rolling and processing equipment, such as rolling mills and annealing furnaces, are also essential. Additionally, the industry relies on a range of supporting services, including logistics, energy, and skilled labor.

Production outputs

The copper plates and sheets produced under HS code 740939 are used in a wide range of applications, including the manufacturing of 741420 Copper; cooking or heating apparatus of a kind used for domestic purposes, and parts thereof, 853710 Boards, panels, consoles, desks, cabinets and other bases, equipped with two or more apparatus of heading 8535 or 8536, for electric control or the distribution of electricity, and 848180 Taps, cocks, valves and similar appliances, for pipes, boiler shells, tanks, vats or the like, including pressure-reducing valves and thermostatically controlled valves. These products are essential components in various industries, contributing to the overall economic development.
