HS v2022 Code: 721030

About iron or non-alloy steel; flat-rolled, width 600mm or more, electrolytically plated or coated with zinc

HS code 721030 covers the classification of flat-rolled iron or non-alloy steel products that are 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. The production and trade of these steel products are integral to the global economy, supporting industries such as automotive, infrastructure development, and consumer goods.

Production process

The production of flat-rolled steel products under HS code 721030 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, flat sheets or strips, often using a process called hot or cold rolling. 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 721030 Iron or non-alloy steel; flat-rolled, width 600mm or more, electrolytically plated or coated with zinc include iron ore, coal, and other alloying elements to produce the base steel. Additionally, the production process requires specialized rolling mills, plating equipment, and a reliable supply of electricity and water. Skilled labor, including metallurgists and machine operators, is also a crucial input for this industry.

Production outputs

The primary output of HS code 721030 is flat-rolled steel products that are electrolytically plated or coated with zinc. These materials are widely used in the manufacture of 870120 Motor vehicles for the transport of goods and 730890 Structures and parts of structures, n.e.s., of iron or steel, as well as in the construction of buildings, bridges, and other infrastructure. The zinc coating provides enhanced corrosion resistance, making these steel products suitable for outdoor and harsh environments.
