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 global steel supply chain, providing essential materials for a wide range of manufacturing and construction applications. The demand for these products is driven by the need for corrosion-resistant, durable, and cost-effective steel solutions across various industries.

The production of HS code 721230 steel products typically involves a series of rolling and coating processes. First, the steel is heated and passed through a series of rollers to achieve the desired thickness and width. The steel is then coated with a layer of zinc, either through a hot-dip galvanization process or a continuous galvanization method, to provide corrosion resistance. The final product is then inspected and prepared for distribution.

The main inputs required for the production of HS code 721230 steel products include raw iron or non-alloy steel, zinc for the coating process, and specialized rolling and coating equipment. The steel is typically sourced from 720810 Iron or non-alloy steel; flat-rolled products, of a width of 600 mm or more, hot-rolled, not clad, plated or coated or 720711 Iron or non-alloy steel; semi-finished products, containing by weight less than 0.25% of carbon producers. The zinc used for the coating process is often sourced from 790111 Zinc; not alloyed, containing by weight 99.99% or more of zinc or 790112 Zinc; not alloyed, containing by weight less than 99.99% of zinc suppliers.

The primary outputs of HS code 721230 are flat-rolled steel products that are plated or coated with zinc, but not through an electrolytic process. These products are widely used in various industries, including construction, automotive, and appliance manufacturing. The outputs of this industry may be consumed by industries covered under codes such as 730810 Iron or steel; structures and parts of structures, n.e.c. in heading no. 7308, 732690 Iron or steel; articles, n.e.c. in chapter 73, and 871120 Motorcycles; with reciprocating internal combustion piston engine, with a cylinder capacity exceeding 50cc but not exceeding 250cc.
