Iron or non-alloy steel; flat-rolled, of a width less than 600mm, electrolytically plated or coated with zinc

HS v2022 Code: 721220

About iron or non-alloy steel; flat-rolled, of a width less than 600mm, electrolytically plated or coated with zinc

HS code 721220 covers the classification of iron or non-alloy steel flat-rolled products that are less than 600mm in width and have been electrolytically plated or coated with zinc. This industry plays a crucial role in the manufacturing and construction sectors, providing essential materials for a wide range of applications, from automotive components to building materials. The global demand for these products is driven by the ongoing industrialization and infrastructure development, particularly in emerging economies.

Production process

The production of flat-rolled steel products under HS code 721220 typically involves a multi-step process. First, raw steel is produced through the smelting of iron ore and other materials. The steel is then rolled into thin sheets or strips, often using a combination of hot and cold rolling techniques. Finally, the steel is electrolytically plated or coated with a layer of zinc, which provides enhanced corrosion resistance and improved surface properties.

Production inputs

The main inputs required for the production of HS code 721220 products include iron ore, coal, and other raw materials used in the steel-making process. Additionally, the industry relies on specialized rolling mills, plating equipment, and other industrial machinery to facilitate the manufacturing process. Energy sources, such as electricity and natural gas, are also crucial inputs for the production of these flat-rolled steel products.

Production outputs

The primary outputs of the HS code 721220 industry are flat-rolled steel products that have been electrolytically plated or coated with zinc. These materials are widely used in the manufacturing of 871000 Motor vehicles, 730890 Structures and parts of structures, and 730810 Bridges and bridge-sections, among other applications. The zinc coating provides enhanced corrosion resistance, making these products suitable for use in outdoor and harsh environments.
