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

HS v2017 Code: 721622

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

HS code 721622 covers the production and trade of iron or non-alloy steel T-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 structural components for a wide range of applications. The demand for these steel products is closely tied to the overall health of the global economy and the pace of construction and infrastructure development activities.

Production process

The production of iron or non-alloy steel T-sections under HS code 721622 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 continuous cast into billets or blooms. These semi-finished steel products are then reheated and passed through a series of rolling mills to shape them into the desired T-section profiles. The hot-rolling, hot-drawing, or extrusion processes are used to achieve the final dimensions and surface finish required for the T-sections.

Production inputs

The main inputs for the production of HS code 721622 iron or non-alloy steel T-sections include iron ore, coal, scrap steel, and other alloying elements such as manganese, chromium, and nickel. Additionally, the industry relies on specialized rolling mills, extrusion presses, and other metalworking equipment to shape the steel into the desired T-section profiles. Energy sources, such as electricity and natural gas, are also crucial inputs for the high-temperature melting and rolling processes.

Production outputs

The primary output of HS code 721622 is iron or non-alloy steel T-sections, which are used in a variety of construction, manufacturing, and infrastructure applications. These T-sections may be further consumed by industries covered under other HS codes, such as 730120 Structures and parts of structures; iron or steel, bridges and bridge-sections, 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, structures and parts of structures, n.e.c. in heading no. 7308.
