HS v2022 Code: 721050
About iron or non-alloy steel; flat-rolled, width 600mm or more, plated or coated with chromium oxides or with chromium and chromium oxides
HS code 721050 covers a crucial category of flat-rolled iron or non-alloy steel products that are plated or coated with chromium oxides or a combination of chromium and chromium oxides. These materials are widely used in various industries, including automotive, construction, and consumer goods, due to their enhanced corrosion resistance, durability, and aesthetic appeal. As a key component of the broader steel industry, this product group plays a significant role in the global economy, supporting a wide range of manufacturing and infrastructure activities.
Production process
The production of HS 721050 flat-rolled steel involves several key steps. First, the raw steel is produced through a process of smelting and refining iron ore, scrap metal, and other inputs. The steel is then rolled into thin, wide sheets or strips using specialized rolling mills. Finally, the steel is coated with chromium oxides or a combination of chromium and chromium oxides, typically through a process of electroplating or chemical deposition, to enhance its corrosion resistance and surface properties.
Production inputs
The main inputs required for the production of HS 721050 flat-rolled steel include iron ore, scrap metal, alloying elements (such as chromium), and various chemicals and materials used in the coating process. Additionally, the industry relies on specialized machinery and equipment, such as smelting furnaces, rolling mills, and electroplating or coating systems. Energy sources, such as electricity and natural gas, are also critical inputs for the various stages of production.
Production outputs
The primary output of HS 721050 is flat-rolled steel products that are plated or coated with chromium oxides or a combination of chromium and chromium oxides. These materials are then consumed by a wide range of downstream industries, including 721090 Iron or non-alloy steel; flat-rolled, width 600mm or more, clad, plated or coated, 732111 (Stoves, ranges, grates, cookers (including those with subsidiary boilers for central heating), barbecues, braziers, gas-rings, plate warmers and similar non-electric domestic appliances, and parts thereof, of iron or steel), and 870810 (Bumpers and parts thereof (including bumper bars), for motor vehicles), among others.
