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

HS v2022 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 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 widely 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 I-sections under HS code 721632 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 ingots or continuous cast into billets or slabs. These semi-finished products are then reheated and passed through a series of rolling mills, where they are shaped into the desired I-section profile. The hot-rolling, hot-drawing, or extrusion processes ensure the I-sections meet the required height and dimensional specifications.

Production inputs

The main inputs for the production of iron or non-alloy steel I-sections under HS code 721632 include iron ore, coal, scrap metal, and other alloying elements as needed. Additionally, the industry requires specialized machinery such as furnaces, casting equipment, and rolling mills to transform the raw materials into the final I-section products. Energy sources, such as electricity and natural gas, are also essential inputs for the various stages of the production process.

Production outputs

The primary output of HS code 721632 is iron or non-alloy steel I-sections, which are widely used in the construction, infrastructure, and manufacturing industries. These structural steel products may be further processed or fabricated into a variety of end-use applications, such as 730120 Structures and parts of structures, of iron or steel; towers and lattice masts, 730830 Structures and parts of structures, of iron or steel; doors, windows and their frames and thresholds for doors, and 842199 Parts for machinery used in the manufacture of pulp, of paper or paperboard. The I-sections produced under this code may also be consumed by industries covered under other HS codes, such as 730110 Structures and parts of structures, of iron or steel; bridges and bridge-sections and 730820 Structures and parts of structures, of iron or steel; towers and lattice masts.
