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 support, 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. Quality control measures, such as dimensional inspections and pressure testing, are often implemented to ensure the products meet industry standards.

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 assembling the components. Additionally, energy sources, such as electricity or natural gas, are needed to power the production processes. Skilled labor, including welders, fabricators, and engineers, is also a crucial input for this industry.

Production outputs

The products covered by HS code 730669 are primarily used as components in various downstream industries. They may be incorporated into 730610 Iron or steel; line pipe of a kind used for oil or gas pipelines, seamless or 730620 Iron or steel; casing, tubing and drill pipe, of a kind used in drilling for oil or gas, seamless for oil and gas applications. They can also be used in 732111 Iron or steel; cooking appliances and plate warmers for domestic use, non-electric and 732190 Iron or steel; parts of cooking appliances and plate warmers for domestic use, non-electric for household appliances, as well as in construction and infrastructure projects.
