Iron or non-alloy steel; angles, shapes and sections, cold-formed or cold-finished, (not obtained from flat-rolled products)

HS v2017 Code: 721669

About iron or non-alloy steel; angles, shapes and sections, cold-formed or cold-finished, (not obtained from flat-rolled products)

HS code 721669 covers a crucial segment of the steel industry, encompassing the production of iron or non-alloy steel angles, shapes, and sections that are cold-formed or cold-finished, rather than obtained from flat-rolled products. These specialized steel products play a vital role in a wide range of industries, from construction and infrastructure to manufacturing and transportation, contributing significantly to the overall economic landscape.

Production process

The production of the steel products covered by HS code 721669 typically involves a multi-step process. First, raw materials, such as iron ore and coal, are smelted in a blast furnace to produce molten pig iron. This pig iron is then refined and alloyed in a basic oxygen furnace or electric arc furnace to create the desired steel composition. The steel is then cast into billets, blooms, or slabs, which are subsequently rolled or extruded into the desired angles, shapes, and sections. Finally, these steel products may undergo further cold-forming or cold-finishing processes, such as bending, cutting, or surface treatment, to achieve the final specifications.

Production inputs

The primary inputs required for the production of the steel products under HS code 721669 include iron ore, coal, and other alloying elements, such as manganese, chromium, and nickel. Additionally, specialized machinery, such as rolling mills, extrusion presses, and cutting equipment, are essential for the cold-forming and cold-finishing processes. Energy, in the form of electricity and natural gas, is also a significant input for the various stages of steel production.

Production outputs

The steel angles, shapes, and sections produced under HS code 721669 are widely used in a variety of industries. These products are often consumed by the 730890 Structures and parts of structures, of iron or steel, n.e.c. industry for the construction of buildings, bridges, and other infrastructure. They are also used in the 870120 Road tractors for semi-trailers and 870210 (Buses with only compression-ignition internal combustion piston engine (diesel or semi-diesel)) industries for the manufacture of vehicle frames and components. Additionally, these steel products may be further processed and incorporated into 732690 Articles of iron or steel, n.e.c. for various industrial and consumer applications.
