Iron or non-alloy steel; angles, shapes and sections, cold-formed or cold-finished, obtained from flat-rolled products

HS v2022 Code: 721661

About iron or non-alloy steel; angles, shapes and sections, cold-formed or cold-finished, obtained from flat-rolled products

HS code 721661 covers a crucial segment of the steel industry, focusing on the production of iron or non-alloy steel angles, shapes, and sections that are cold-formed or cold-finished from flat-rolled products. These specialized steel products are widely used in construction, manufacturing, and various other industrial applications, making them an integral part of the global economy.

Production process

The production of the steel products covered under HS code 721661 typically involves a multi-step process. First, flat-rolled steel is subjected to cold-forming or cold-finishing techniques, such as rolling, bending, or pressing, to create the desired angles, shapes, and sections. These processes allow for the precise shaping and finishing of the steel without the need for extensive heating, which helps to maintain the material's structural integrity and properties.

Production inputs

The key inputs for the production of HS code 721661 steel products include high-quality flat-rolled steel, specialized machinery for cold-forming and cold-finishing, and skilled labor. The flat-rolled steel may be sourced from 720810 Hot-rolled flat-rolled products of iron or non-alloy steel, 720920 Cold-rolled flat-rolled products of iron or non-alloy steel, or other relevant HS codes, depending on the specific requirements of the final product.

Production outputs

The steel angles, shapes, and sections produced under HS code 721661 are widely used in various industries, such as construction, manufacturing, and infrastructure development. These products are often consumed by industries covered under HS codes like 730120 Angles, shapes and sections, of iron or non-alloy steel, 730830 Structures and parts of structures, of iron or steel, and 731010 Tanks, casks, drums, cans, boxes and similar containers, of iron or steel, among others.
