Steel, alloy (not stainless steel); seamless, cold-drawn or cold-rolled (cold-reduced), tubes, pipes and hollow profiles of circular cross-section

HS v2022 Code: 730451

About steel, alloy (not stainless steel); seamless, cold-drawn or cold-rolled (cold-reduced), tubes, pipes and hollow profiles of circular cross-section

HS code 730451 covers a critical segment of the steel industry, encompassing the production of seamless, cold-drawn or cold-rolled alloy steel tubes, pipes, and hollow profiles of circular cross-section. These products are essential components in a wide range of industries, including construction, automotive, energy, and manufacturing, making them a vital part of the global economy.

Production process

The production of the steel products described by HS code 730451 typically involves a multi-step process. First, alloy steel billets or ingots are heated and then pierced or extruded to create a hollow shell. The hollow shell is then cold-drawn or cold-rolled to the desired dimensions and specifications. This process enhances the strength and durability of the final product, making it suitable for a variety of demanding applications.

Production inputs

The main inputs required for the production of the steel products covered by HS code 730451 include alloy steel raw materials, such as 720241 Ferro-chromium, containing by weight more than 4% of carbon and 720221 Ferro-silicon-manganese, as well as specialized machinery for piercing, drawing, and rolling the steel. Additionally, energy sources, such as electricity and natural gas, are essential for the various stages of the manufacturing process.

Production outputs

The steel products described by HS code 730451 are primarily used as components in a wide range of industries, including construction, automotive, energy, and manufacturing. These seamless, cold-drawn or cold-rolled alloy steel tubes, pipes, and hollow profiles are often consumed by industries covered by other HS codes, such as 730610 Line pipe of a kind used for oil or gas pipelines, 730630 Other, welded, of circular cross-section, of iron or non-alloy steel, and 730661 Other, welded, of circular cross-section, of stainless steel.
