Copper; tubes and pipes, of copper-zinc base alloys (brass)

HS v2022 Code: 741121

About copper; tubes and pipes, of copper-zinc base alloys (brass)

HS code 741121 covers the trade of copper tubes and pipes made from copper-zinc base alloys, commonly known as brass. Brass is a versatile alloy that combines the desirable properties of copper and zinc, making it a popular choice for a wide range of applications. The copper tubes and pipes classified under this code are essential components in various industries, contributing to the broader economic landscape.

Production process

The production of copper tubes and pipes under HS code 741121 typically involves a multi-step process. First, the copper and zinc are melted and alloyed to create the desired brass composition. The molten alloy is then cast into billets or ingots, which are subsequently extruded or drawn through dies to form the tubes and pipes. Depending on the specific application, the tubes and pipes may undergo additional processing, such as annealing, cutting, or threading, to meet the required specifications.

Production inputs

The primary inputs for the production of copper tubes and pipes under HS code 741121 are copper and zinc, the two main components of brass. Additionally, the industry requires specialized machinery and equipment, such as melting furnaces, extrusion presses, and cutting tools, to facilitate the manufacturing process. Energy sources, such as electricity or natural gas, are also crucial inputs for the various stages of production.

Production outputs

The copper tubes and pipes classified under HS code 741121 are widely used in a variety of industries, including plumbing, HVAC (Heating, Ventilation, and Air Conditioning), automotive, and construction. These brass components are often consumed by industries represented by other HS codes, such as 842511 Pulley tackle and hoists, 842512 Winches; not powered by electric motor, and 842519 Winches; powered by electric motor.
