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

HS code 741121 covers the import and export of copper tubes and pipes made from copper-zinc base alloys, commonly known as brass. This industry plays a crucial role in the global manufacturing and construction sectors, providing essential components for a wide range of applications, from plumbing and heating systems to industrial equipment and decorative fixtures. The demand for these products is driven by the ongoing need for durable, corrosion-resistant, and versatile copper-based materials across various industries.

The production of copper tubes and pipes under HS code 741121 typically involves a multi-step process. First, the copper-zinc alloy is melted and cast into billets or ingots. These are then heated and extruded or drawn through a die to create the desired tube or pipe shape. Depending on the specific application, the tubes may undergo additional processing, such as annealing, bending, or threading, to meet the required specifications. Quality control measures, including dimensional checks and testing for mechanical properties, are crucial throughout the manufacturing process to ensure the final products meet industry standards.

The main inputs required for the production of copper tubes and pipes under HS code 741121 include copper and zinc, the primary raw materials. Specialized machinery, such as extrusion presses, draw benches, and annealing furnaces, are also essential for the manufacturing process. Additionally, energy sources, such as electricity or natural gas, are needed to power the production equipment, and skilled labor is required to operate the machinery and maintain quality control.

The primary output of HS code 741121 is copper tubes and pipes, which are widely used in various industries. These products are often consumed by manufacturers of 731100 Structures and parts of structures, of iron or steel, 732111 Cooking appliances and plate warmers, and 842139 Filtering or purifying machinery and apparatus for gases, among others. The versatility of copper-based alloys makes these tubes and pipes suitable for applications ranging from plumbing and HVAC systems to industrial equipment and decorative architectural elements.
