Copper; tube or pipe fittings (e.g. couplings, elbows, sleeves)

HS v2017 Code: 7412

About copper; tube or pipe fittings (e.g. couplings, elbows, sleeves)

HS code 7412 covers a range of copper tube and pipe fittings, including couplings, elbows, and sleeves. These components play a crucial role in the construction, plumbing, and industrial piping industries, enabling the efficient and secure connection of copper pipes and tubes. As a key part of the broader 74 Copper and articles thereof industry, the production and trade of these fittings contribute significantly to global infrastructure development and the flow of goods and resources.

Production process

Copper tube and pipe fittings are typically manufactured through a combination of casting, machining, and finishing processes. The raw copper material is first melted and cast into the desired shape, such as a coupling or elbow. The cast components are then machined to precise dimensions and tolerances, ensuring a perfect fit for the intended pipe or tube. Finally, the fittings undergo various finishing processes, such as polishing or plating, to enhance their appearance and corrosion resistance.

Production inputs

The primary inputs for the production of copper tube and pipe fittings include high-purity copper, as well as various alloying elements like zinc or tin to improve the material's properties. Specialized machinery, such as casting equipment, lathes, and polishing tools, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce capable of operating these machines and performing the necessary finishing work.

Production outputs

The main outputs of HS code 7412 are the various types of copper tube and pipe fittings, including couplings, elbows, sleeves, and other connection components. These fittings are widely used in the construction, plumbing, and industrial piping sectors, where they are essential for the assembly and maintenance of copper pipe systems. The outputs of this industry are often consumed by other HS codes, such as 7411 Copper tubes and pipes, 8481 Taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like, including pressure-reducing valves and thermostatically controlled valves, and 8708 Parts and accessories of the motor vehicles of headings 8701 to 8707.
