About copper; strip, of a thickness exceeding 0.15mm, of copper-zinc base alloys (brass), in coils

HS code 740921 covers the import and export of copper strip made from copper-zinc base alloys, commonly known as brass. This industry plays a crucial role in the global metal manufacturing and fabrication sectors, providing essential raw materials for a wide range of applications, from construction and plumbing to electrical and automotive components. The demand for these copper-based alloy products is driven by their unique properties, such as corrosion resistance, malleability, and electrical conductivity, making them indispensable in various industries.

Production process

The production of copper strip under HS code 740921 typically involves a multi-step process. First, the copper-zinc 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 strips may undergo further processing, such as annealing, to enhance their mechanical properties and surface finish. Finally, the copper strips are coiled and prepared for distribution and use in various manufacturing processes.

Production inputs

The key inputs for the production of copper strip under HS code 740921 include copper and zinc, the primary raw materials. Additionally, the industry relies on specialized rolling mills, annealing furnaces, and other metalworking equipment to transform the raw materials into the final product. Energy sources, such as electricity or natural gas, are also essential for the various production stages.

Production outputs

The copper strips produced under HS code 740921 are primarily used as raw materials in the manufacturing of a wide range of products, including 741420 Sanitary ware and parts thereof, of copper, 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 copper-based alloy strips are highly versatile and find applications in the construction, electrical, plumbing, and automotive industries, among others.
