Iron or steel; structures and parts thereof, bridges and bridge-sections

HS v2022 Code: 730810

About iron or steel; structures and parts thereof, bridges and bridge-sections

HS code 730810 covers the import and export of iron or steel structures and parts thereof, including bridges and bridge-sections. This industry plays a crucial role in the construction and infrastructure sectors, providing essential components for the development of transportation networks, public works, and industrial facilities. As a key contributor to economic growth and development, the 730810 industry is closely tied to the broader trends and demands within the global construction and engineering markets.

Production process

The production of iron or steel structures and parts for bridges and bridge-sections typically involves a combination of fabrication, welding, and assembly techniques. Manufacturers may utilize computer-aided design (CAD) software to create detailed plans and models, followed by the cutting, shaping, and joining of steel or iron components using advanced welding technologies. Quality control measures, such as non-destructive testing, are often implemented to ensure the structural integrity and safety of the final products.

Production inputs

The main inputs required for the 730810 industry include raw materials such as steel or iron, as well as specialized machinery and equipment for fabrication, welding, and assembly. Additionally, the industry relies on skilled labor, including engineers, technicians, and welders, to design, produce, and assemble the various components. Energy sources, such as electricity and natural gas, are also necessary for the manufacturing processes.

Production outputs

The primary outputs of the 730810 industry are the finished iron or steel structures and parts, including bridges, bridge-sections, and other infrastructure components. These products are then consumed by the 230110 Construction industry, 230120 Civil engineering industry, and 230130 Building construction industry, among others, for the construction and maintenance of transportation networks, public works, and industrial facilities.
