Iron or steel (excluding cast iron); tubes, pipes and hollow profiles (not seamless), n.e.c. in chapter 73

HS v2022 Code: 7306

About iron or steel (excluding cast iron); tubes, pipes and hollow profiles (not seamless), n.e.c. in chapter 73

HS code 7306 covers a diverse range of iron and steel tubes, pipes, and hollow profiles that are not seamless. These products are widely used in various industries, including construction, oil and gas, automotive, and manufacturing. They play a crucial role in the global economy, facilitating the transportation of fluids, gases, and other materials, as well as providing structural support in a wide range of applications.

Production process

The production of the products covered under HS code 7306 typically involves several key steps. First, the raw materials, such as steel or iron, are melted and formed into the desired shape using techniques like rolling, drawing, or extrusion. The resulting tubes, pipes, or hollow profiles may then undergo additional processing, such as cutting, welding, or coating, to meet specific requirements or applications.

Production inputs

The main inputs required for the production of HS code 7306 products include steel or iron as the primary raw material, as well as various alloying elements, such as chromium, nickel, or manganese, to enhance the material properties. Additionally, specialized machinery and equipment, such as rolling mills, drawing machines, and welding stations, are essential for the manufacturing process.

Production outputs

The products covered under HS code 7306 are used in a wide range of applications, including 7307 Tube or pipe fittings, of iron or steel, 7308 Structures and parts of structures, of iron or steel, and 8431 Parts suitable for use solely or principally with the machinery of headings 8425 to 8430. These tubes, pipes, and hollow profiles are often consumed by industries like construction, oil and gas, automotive, and manufacturing, where they serve as essential components for infrastructure, transportation, and industrial processes.
