Iron or non-alloy steel; L sections, hot-rolled, hot-drawn or extruded, of a height of less than 80mm
HS v2022 Code: 721621
About iron or non-alloy steel; l sections, hot-rolled, hot-drawn or extruded, of a height of less than 80mm
HS code 721621 covers the classification of iron or non-alloy steel L-sections that are hot-rolled, hot-drawn, or extruded, with a height of less than 80mm. This industry plays a crucial role in the construction, manufacturing, and infrastructure sectors, providing essential building materials for a wide range of applications. The production and trade of these steel products are integral to the global economy, supporting economic growth and development across various industries.
Production process
The production of iron or non-alloy steel L-sections under HS code 721621 typically involves a multi-step process. The raw materials, such as iron ore and coal, are first smelted in a blast furnace to produce molten pig iron. This pig iron is then refined in a basic oxygen furnace or electric arc furnace to remove impurities and produce high-quality steel. The steel is then rolled, drawn, or extruded into the desired L-shaped sections, with a height of less than 80mm, through a series of controlled heating and mechanical processes.
Production inputs
The main inputs required for the production of HS code 721621 products include iron ore, coal, and other alloying elements, such as manganese, chromium, and nickel. Additionally, the industry relies on specialized machinery and equipment, such as rolling mills, drawing machines, and extrusion presses, to shape the steel into the desired L-sections. Energy sources, such as electricity and natural gas, are also crucial inputs for the various stages of the production process.
Production outputs
The primary output of HS code 721621 is iron or non-alloy steel L-sections, which are used in a wide range of applications, including construction, infrastructure, and manufacturing. These L-sections may be further processed or incorporated into larger assemblies, such as 730120 Structures and parts of structures; iron or steel, towers and lattice masts, 730830 Structures and parts of structures; iron or steel, doors, windows and their frames and thresholds for doors, and 730890 Structures and parts of structures; iron or steel, other. The L-sections produced under this code are essential building blocks for various industries and contribute to the overall development and growth of the global economy.
