Copper; plates, sheets and strip, of a thickness exceeding 0.15mm, of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver)

HS v2022 Code: 740940

About copper; plates, sheets and strip, of a thickness exceeding 0.15mm, of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver)

HS code 740940 covers copper plates, sheets, and strips that are more than 0.15mm thick, made from copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver). These copper-based alloys are valued for their corrosion resistance, electrical conductivity, and decorative properties, making them essential materials in a wide range of industries, from construction and electronics to transportation and consumer goods.

Production process

The production of copper plates, sheets, and strips under HS code 740940 typically involves a multi-step process. First, the copper-nickel or copper-nickel-zinc alloy is melted and cast into ingots or billets. These are then subjected to hot and cold rolling processes to reduce the thickness and achieve the desired dimensions. The rolled material may also undergo annealing, pickling, and other finishing treatments to enhance its properties and surface quality.

Production inputs

The main inputs required for the production of products under HS code 740940 include copper, nickel, and zinc as the primary raw materials. Specialized machinery such as melting furnaces, rolling mills, and finishing equipment are also essential. Additionally, energy sources, such as electricity or natural gas, and various chemicals for processing and finishing the metal are important inputs.

Production outputs

The copper plates, sheets, and strips produced under HS code 740940 are widely used in a variety of applications. They may be further processed and incorporated into 732690 Other articles of copper, n.e.s., 853710 Boards, panels, consoles, desks, cabinets and other bases for the goods of heading 8537, not equipped with their apparatus, or 870710 (Bodies (including cabs), for the motor vehicles of headings 8701 to 8705), among other products. The corrosion-resistant and decorative properties of these copper-based alloys make them valuable in construction, electrical and electronic equipment, and transportation industries.
