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

HS v2017 Code: 721632

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

HS code 721632 covers the production and trade of iron or non-alloy steel I-sections that are hot-rolled, hot-drawn, or extruded, with a height of 80mm or more. This industry plays a crucial role in the construction and infrastructure sectors, providing essential building materials for a wide range of projects, from residential and commercial buildings to bridges, railways, and industrial facilities. The demand for these steel products is closely tied to the overall health of the global economy and construction industry.

Production process

The production of iron or non-alloy steel I-sections under HS code 721632 typically involves a multi-step process. First, raw materials such as iron ore, coal, and scrap steel are melted in a blast furnace or electric arc furnace to produce molten steel. The molten steel is then cast into ingots or continuous cast into billets or slabs. These semi-finished products are then reheated and passed through a series of rolling mills to shape them into the desired I-section profiles. The hot-rolling, hot-drawing, or extrusion processes are carefully controlled to ensure the desired dimensions, strength, and surface finish of the final products.

Production inputs

The main inputs required for the production of HS code 721632 steel I-sections include iron ore, coal, scrap steel, and other alloying elements such as manganese, silicon, and chromium. Specialized rolling mills, extrusion presses, and other metalworking equipment are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce, including metallurgists, engineers, and technicians, to operate the production facilities and ensure quality control.

Production outputs

The primary output of HS code 721632 is hot-rolled, hot-drawn, or extruded iron or non-alloy steel I-sections, which are used extensively in the construction and infrastructure industries. These steel products are often consumed by industries covered under other HS codes, 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, as they are essential components in the fabrication of various structural elements.
