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

HS v2022 Code: 721633

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

HS code 721633 covers the production and trade of iron or non-alloy steel H-sections that are hot-rolled, hot-drawn, or extruded to a height of 80mm or more. These structural steel products are essential components in the construction, infrastructure, and manufacturing industries, playing a crucial role in the broader economy. They are used in the fabrication of buildings, bridges, machinery, and various other applications that require strong, durable, and versatile materials.

Production process

The production of iron or non-alloy steel H-sections with a height of 80mm or more typically involves a multi-step process. First, raw materials such as iron ore, coal, and scrap steel are melted in a furnace to produce molten steel. The molten steel is then cast into ingots or continuously cast into long, semi-finished products known as billets or blooms. These semi-finished products are then reheated and passed through a series of rolling mills, where they are shaped and formed into the desired H-section profile. The final products are then cooled, inspected, and prepared for distribution and use.

Production inputs

The main inputs required for the production of HS code 721633 products include iron ore, coal, and scrap steel as the primary raw materials. Additionally, specialized machinery such as furnaces, rolling mills, and extrusion equipment are essential for the manufacturing process. Energy sources, such as electricity and natural gas, are also crucial inputs for the various stages of production.

Production outputs

The primary output of HS code 721633 is hot-rolled, hot-drawn, or extruded iron or non-alloy steel H-sections with a height of 80mm or more. These structural steel products are widely used in the construction industry, where they are incorporated into the framing and support systems of buildings, bridges, and other infrastructure projects. They are also consumed by the manufacturing sector, where they are used in the production of machinery, equipment, and various industrial applications. Other related HS codes that may consume the output of 721633 include 730120 Iron or steel; angles, shapes and sections, welded, 730110 Iron or steel; sheet piling, whether or not drilled, punched or made from assembled elements, and 730290 Iron or steel; track construction material for railways or tramways, such as rails, check-rails and rack rails, switch blades, crossing frogs, point rods and other crossing pieces, sleepers, fish-plates, chairs, chair wedges, sole plates, rail clips, bedplates, ties and the like, and parts thereof, among others.
