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

HS v2022 Code: 721041

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

HS code 721041 covers a crucial category of iron and non-alloy steel products - flat-rolled steel sheets and plates that are corrugated and coated with zinc. These materials are widely used in the construction, automotive, and manufacturing industries, playing a vital role in the global economy. Their versatility, durability, and corrosion resistance make them indispensable for a wide range of applications, from roofing and siding to automotive body panels and industrial equipment.

Production process

The production of 721041 steel products typically involves a multi-step process. First, iron ore and other raw materials are smelted in a blast furnace to produce molten pig iron. This pig iron is then refined and alloyed in a basic oxygen furnace or electric arc furnace to create the desired steel composition. The steel is then cast into slabs or billets, which are subsequently rolled and flattened into thin sheets or plates. Finally, the flat-rolled steel is corrugated and coated with a layer of zinc, either through a hot-dip galvanization process or an electrolytic coating method, to enhance its corrosion resistance and weatherproofing properties.

Production inputs

The primary inputs for the production of 721041 steel products include iron ore, coal, and other alloying elements such as manganese, chromium, and nickel. Specialized rolling mills, furnaces, and coating equipment are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce of metallurgists, engineers, and technicians to operate the production facilities and ensure quality control.

Production outputs

The primary outputs of HS code 721041 are corrugated, zinc-coated steel sheets and plates, which are widely used in the construction, automotive, and industrial sectors. These materials are often consumed by industries covered under other HS codes, such as 730810 Structures and parts of structures, of iron or steel; bridges and bridge-sections, towers, lattice masts, roofs, roofing frameworks, doors and windows and their frames and thresholds for doors, shutters, balustrades, pillars and columns, 870600 Motor vehicles; chassis fitted with engines, for the motor vehicles of headings 8701 to 8705, and 842199 Machinery parts; for filtering or purifying machinery or apparatus for liquids or gases, among others.
