About steel, alloy; tubes, pipes and hollow profiles (other than stainless steel or seamless), welded, of circular cross-section, n.e.c. in chapter 73

HS code 730650 covers a crucial segment of the steel industry, focusing on the production of welded, circular cross-section tubes, pipes, and hollow profiles made from alloy steel. These products play a vital role in various industries, including construction, manufacturing, and infrastructure development, making them an essential component of the global economy.

Production process

The production of the steel products covered under HS code 730650 typically involves a multi-step process. First, the raw materials, including alloy steel, are melted and refined to achieve the desired chemical composition and properties. The molten steel is then formed into the desired shape, either through a continuous casting process or by rolling and drawing. Finally, the steel is welded along the seam to create the final tubular or hollow profile product.

Production inputs

The main inputs required for the production of the steel products under HS code 730650 include alloy steel, which serves as the primary raw material. Additionally, specialized machinery, such as welding equipment, rolling mills, and drawing machines, are essential for the manufacturing process. Energy sources, such as electricity or natural gas, are also necessary to power the production facilities.

Production outputs

The steel tubes, pipes, and hollow profiles produced under HS code 730650 are widely used in various industries. They are often consumed by manufacturers of 730610 Steel, stainless; tubes, pipes and hollow profiles, seamless, 730620 Steel, other than stainless; tubes, pipes and hollow profiles, seamless, and 730630 Steel, other than stainless; tubes, pipes and hollow profiles, welded, of circular cross-section, who incorporate these products into their own manufacturing processes or construction projects.
