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

HS v2017 Code: 721640

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

HS code 721640 covers the classification of iron or non-alloy steel L or T 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 manufacturing sectors, providing essential structural components for a wide range of applications. The demand for these products is closely tied to the overall health of the global economy, as they are integral to the development of infrastructure, buildings, and various industrial projects.

Production process

The production of iron or non-alloy steel L or T sections classified under HS code 721640 typically involves a series of hot-rolling, hot-drawing, or extrusion processes. In the hot-rolling process, steel billets or slabs are fed into a rolling mill, where they are subjected to high temperatures and pressure to shape them into the desired L or T sections. Hot-drawing, on the other hand, involves pulling the steel through a die to create the required profile. Extrusion is another common technique, where the steel is forced through a die to produce the desired cross-sectional shape.

Production inputs

The main inputs required for the production of HS code 721640 products include iron or non-alloy steel raw materials, such as billets or slabs. Additionally, the industry relies on specialized machinery, such as rolling mills, drawing equipment, and extrusion presses, as well as energy sources (e.g., electricity, natural gas) to power the production processes. The availability and quality of these inputs are crucial for the industry to meet the demand for its products.

Production outputs

The primary output of the industry covered by HS code 721640 is L or T sections of iron or non-alloy steel, which are used in a wide range of construction and manufacturing applications. These products may be further consumed by industries classified 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 731010 Tanks, casks, drums, cans, boxes and similar containers; iron or steel, of a capacity not exceeding 300l, not fitted with mechanical or thermal equipment.

Revisions to 721640
