About iron or steel (excluding cast iron); tubes, pipes and hollow profiles (not seamless), n.e.c. in chapter 73, welded, of non-circular cross-section (not square or rectangular cross-section)

HS code 730669 covers a wide range of iron or steel tubes, pipes, and hollow profiles that are welded and have a non-circular cross-section (excluding square or rectangular). These products are essential components in various industries, including construction, manufacturing, and infrastructure development. They are used in applications such as plumbing, HVAC systems, and structural frameworks, making them a crucial part of the global economy.

Production process

The production of the products covered by HS code 730669 typically involves a multi-step process. First, the raw materials, such as steel coils or sheets, are cut and formed into the desired non-circular cross-section. The pieces are then welded together using techniques like arc welding or laser welding to create the final tube or pipe. Depending on the specific application, additional finishing processes, such as coating or galvanizing, may be applied to enhance the product's durability and corrosion resistance.

Production inputs

The main inputs required for the production of the products under HS code 730669 include steel coils or sheets, welding equipment, and various tools and machinery for cutting, forming, and shaping the materials. Additionally, energy sources, such as electricity or natural gas, are needed to power the production processes. Skilled labor, including welders, fabricators, and machine operators, is also a crucial input for this industry.

Production outputs

The products covered by HS code 730669 are primarily used as components in various industries. They are often consumed by manufacturers of 730120 Iron or steel; welded, riveted or similarly closed, not seamless, tubes, pipes and hollow profiles, of circular cross-section, of iron or non-alloy steel, 730290 Iron or steel; welded, not seamless, tubes, pipes and hollow profiles, of circular cross-section, of iron or non-alloy steel, not cast iron, and 730300 Iron or steel; tubes, pipes and hollow profiles, cast, of iron or steel, among others. These products play a vital role in the construction, infrastructure, and industrial sectors, contributing to the overall economic development.
