Copper; tubes and pipes, of copper alloys (other than copper-zinc, copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel-silver))

HS code 741129 covers a range of copper alloy tubes and pipes, excluding those made from copper-zinc, copper-nickel, or copper-nickel-zinc alloys. These copper alloy products are essential components in various industries, including construction, plumbing, and manufacturing. They offer unique properties such as corrosion resistance, thermal conductivity, and malleability, making them valuable in a wide array of applications across the global economy.

The production of copper alloy tubes and pipes under HS code 741129 typically involves a multi-step process. First, the desired copper alloy is melted and cast into billets or ingots. These are then heated and extruded or drawn through a die to create the initial 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.

The primary inputs for the production of copper alloy tubes and pipes under HS code 741129 include copper, alloying elements (such as nickel, tin, or zinc), and energy sources for the melting and shaping processes. Specialized machinery, such as extrusion presses and drawing equipment, are also essential to the manufacturing process. Additionally, skilled labor is required to operate the equipment and ensure consistent quality.

The copper alloy tubes and pipes produced under HS code 741129 are used in a variety of applications, including plumbing systems, HVAC equipment, industrial machinery, and construction projects. These products may be further processed or incorporated into finished goods, such as 761610 Aluminum; structures and parts of structures or 842139 Machinery and apparatus for filtering or purifying gases. The versatility of these copper alloy tubes and pipes makes them an important component in many industries and supply chains.
