Iron or non-alloy steel; T sections, hot-rolled, hot-drawn or extruded, of a height less than 80mm
HS v2022 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 classification 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 industrial activity.
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 billets or blooms, which are subsequently rolled or extruded into the desired T-section shape. The hot-rolling or hot-drawing process helps to align the grain structure of the steel, improving its strength and durability. Finally, the T-sections may undergo additional finishing processes, such as cutting, trimming, or surface treatment, to meet specific customer requirements.
Production inputs
The main inputs required for the production of iron or non-alloy steel T-sections under HS code 721622 include raw materials such as iron ore, coal, and scrap steel. Additionally, the industry relies on specialized machinery and equipment, such as furnaces, rolling mills, and extrusion presses, to transform the raw materials into the final products. Energy sources, such as electricity and 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 721622 is iron or non-alloy steel T-sections, which are used in a wide range of construction and manufacturing applications. These T-sections may be consumed by industries such as 730110 Structures and parts of structures, of iron or steel; bridges and bridge-sections, 730120 Towers and lattice masts, of iron or steel, and 730210 Railway or tramway track construction material of iron or steel; rails, among others. The T-sections can be further processed or fabricated into more complex structures and components, contributing to the overall growth and development of the construction, infrastructure, and manufacturing sectors.
