Iron or non-alloy steel; flat-rolled, width less than 600mm, plated or coated with zinc (not electrolytically)

HS v2022 Code: 721230

About iron or non-alloy steel; flat-rolled, width less than 600mm, plated or coated with zinc (not electrolytically)

HS code 721230 covers a specific type of flat-rolled iron or non-alloy steel products that are plated or coated with zinc, but not through an electrolytic process. 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 factors such as infrastructure development, urbanization, and the need for corrosion-resistant materials in various industries.

Production process

The production of flat-rolled steel products under HS code 721230 typically involves a series of processes, including hot or cold rolling, pickling, and zinc plating or coating. The steel is first heated and then passed through a series of rollers to achieve the desired thickness and width. The surface is then cleaned and treated to remove any impurities, and finally, the steel is coated with a layer of zinc to provide corrosion resistance.

Production inputs

The main inputs required for the production of HS code 721230 products include iron or non-alloy steel, zinc, and various chemicals and equipment used in the rolling, pickling, and coating processes. Specialized machinery, such as rolling mills, pickling lines, and coating lines, are also essential for the efficient and high-quality production of these flat-rolled steel products.

Production outputs

The primary outputs of HS code 721230 are flat-rolled iron or non-alloy steel products that are plated or coated with zinc, but not through an electrolytic process. These materials are widely used in the manufacturing of 731000 Structures and parts of structures, of iron or steel, 732690 Other articles of iron or steel, and 870810 Bumpers and parts thereof, for motor vehicles.
