Iron or non-alloy steel; angles, shapes and sections, cold-formed or cold-finished, (not obtained from flat-rolled products)

HS v2022 Code: 721669

About iron or non-alloy steel; angles, shapes and sections, cold-formed or cold-finished, (not obtained from flat-rolled products)

HS code 721669 covers a crucial segment of the steel industry, encompassing the production of iron or non-alloy steel angles, shapes, and sections that are cold-formed or cold-finished, rather than obtained from flat-rolled products. These specialized steel products are essential components in a wide range of industries, from construction and infrastructure to manufacturing and transportation. Their unique properties, such as enhanced strength and durability, make them indispensable in applications where traditional steel products may not suffice.

Production process

The production of the steel products covered under HS code 721669 typically involves a multi-step process. First, raw materials, such as iron ore and coal, are smelted in a blast furnace to produce molten pig iron. This pig iron is then refined in a basic oxygen furnace or electric arc furnace to remove impurities and produce high-quality steel. The steel is then rolled, extruded, or otherwise shaped into the desired angles, shapes, and sections, often using specialized cold-forming or cold-finishing techniques to impart the desired properties.

Production inputs

The primary inputs required for the production of the steel products under HS code 721669 include iron ore, coal, and other raw materials necessary for steel production, as well as specialized machinery and equipment for the cold-forming or cold-finishing processes. Additionally, skilled labor and advanced manufacturing techniques are crucial for ensuring the quality and consistency of the final products.

Production outputs

The steel angles, shapes, and sections produced under HS code 721669 are widely used in a variety of industries, including 730110 Structures and parts of structures, of iron or steel; plates, rods, angles, shapes, sections, tubes and the like, prepared for use in structures, 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 732690 Other articles of iron or steel. These products are essential for the construction, infrastructure, and manufacturing sectors, contributing to the overall strength and resilience of the global economy.
