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

HS v2017 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 and manufacturing sectors, providing essential raw materials for the production of a wide range of products. The demand for these steel sections is closely tied to the overall health of the global economy, as they are used extensively in infrastructure development, building construction, and various industrial applications.

Production process

The production of iron or non-alloy steel L-sections classified under HS code 721621 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 semi-finished products, such as billets or blooms. These semi-finished products are then reheated and passed through a series of rolling mills, where they are shaped into the desired L-section profile. The hot-rolling, hot-drawing, or extrusion processes are used to achieve the final dimensions and surface finish required for the product.

Production inputs

The main inputs required for the production of iron or non-alloy steel L-sections under HS code 721621 include iron ore, coal, scrap metal, and other alloying elements, such as manganese or silicon, depending on the desired steel composition. Additionally, the industry relies on specialized machinery, such as furnaces, casting equipment, and rolling mills, to transform the raw materials into the final products. Energy sources, such as electricity or natural gas, are also essential for the various stages of the production process.

Production outputs

The primary output of the industry covered by HS code 721621 is iron or non-alloy steel L-sections, which are used in a wide range of applications. These steel sections are often consumed by industries such as 730110 Construction, 731100 Containers and packaging, and 732510 Furniture, where they are used as structural components, framing materials, and various other applications. The output of this industry may also be further processed or fabricated into more complex products, such as those classified under 730120 Structures and parts of structures, 730890 Other structures and parts of structures, and 732690 Other articles of iron or steel, among others.
