Iron or non-alloy steel; L or T sections, hot-rolled, hot-drawn or extruded, of a height of 80mm or more

HS v2022 Code: 721640

About iron or non-alloy steel; l or t sections, hot-rolled, hot-drawn or extruded, of a height of 80mm or more

HS code 721640 covers a crucial category of iron and non-alloy steel products - L or T sections that are hot-rolled, hot-drawn, or extruded to a height of 80mm or more. These structural steel components are essential inputs for a wide range of industries, including construction, manufacturing, and infrastructure development. They play a vital role in the global economy, supporting the construction of buildings, bridges, machinery, and other critical infrastructure.

Production process

The production of the steel products covered by HS code 721640 typically involves a multi-step process. First, raw materials such as iron ore, coal, and scrap metal are melted in a furnace to produce molten steel. The molten steel is then cast into ingots or continuous cast into billets or blooms. These semi-finished steel products are then reheated and passed through a series of rolling mills, where they are shaped into the desired L or T sections. The final products may undergo additional heat treatment or finishing processes to meet specific requirements.

Production inputs

The main inputs required for the production of HS code 721640 steel products include iron ore, coal, scrap metal, and various alloying elements such as manganese, chromium, and nickel. Specialized rolling mills, furnaces, and other metalworking equipment are also essential for the manufacturing process. Additionally, skilled labor, energy, and transportation infrastructure are important inputs for this industry.

Production outputs

The steel products covered by HS code 721640 are primarily used as structural components in construction, manufacturing, and infrastructure projects. They are often consumed by industries such as 730110 Structures and parts of structures, of iron or steel; bridges and bridge-sections, 730120 Structures and parts of structures, of iron or steel; towers and lattice masts, and 730840 Structures and parts of structures, of iron or steel; equipment for scaffolding, shuttering, propping or pit-propping. These L or T sections may also be used in the production of machinery, vehicles, and other industrial applications.
