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

HS v2017 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 infrastructure development, making them an integral part of the global economy.

Production process

The production of the items covered under HS code 721661 typically involves a multi-step process. First, flat-rolled steel products are 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 sizing of the steel components without the need for extensive heating, which can help preserve the material's properties and reduce energy consumption.

Production inputs

The main inputs required for the production of items under HS code 721661 include flat-rolled steel products, which serve as the raw material. Additionally, specialized machinery and equipment, such as rolling mills, presses, and bending machines, are essential for the cold-forming and cold-finishing processes. Skilled labor, energy resources, and various consumables, such as lubricants and coolants, are also necessary for the efficient operation of this industry.

Production outputs

The primary outputs of the industry covered by HS code 721661 are the cold-formed or cold-finished iron or non-alloy steel angles, shapes, and sections. These products are widely used in the construction of buildings, bridges, and other infrastructure projects, as well as in the manufacturing of various metal structures and components. The outputs of this industry may be further consumed by industries covered under other HS codes, such as 730120 Structures and parts of structures; iron or steel, towers and lattice masts and 730890 Structures and parts of structures; iron or steel, n.e.c. in heading no. 7308.
