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

HS v2017 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 crucial segment of the steel industry, encompassing the production of seamless, cold-drawn or cold-rolled (cold-reduced) tubes, pipes, and hollow profiles of circular cross-section made from alloy steel (excluding stainless steel). These products are widely used in various industrial applications, from oil and gas pipelines to automotive components and construction materials, making them an integral part of the global economy.

Production process

The production of the items classified under HS code 730451 typically involves a multi-step process. First, alloy steel billets or ingots are heated and then pierced to create a hollow shell. This shell is then further processed through cold-drawing or cold-rolling techniques to achieve the desired dimensions and surface finish. The cold-working process enhances the strength and durability of the final products.

Production inputs

The main inputs required for the production of the items under HS code 730451 include alloy steel raw materials, such as 720221 Ferro-chromium, 720229 Ferro-silico-chromium, and 720241 Ferro-molybdenum. Additionally, specialized machinery for piercing, drawing, and rolling the steel is essential. Energy sources, such as electricity or natural gas, are also crucial for the various heating and processing steps involved.

Production outputs

The seamless, cold-drawn or cold-rolled tubes, pipes, and hollow profiles produced under HS code 730451 find applications in a wide range of industries. They are commonly used in the 730511 Line pipe of a kind used for oil or gas pipelines, 730512 Casing, tubing and drill pipe, of a kind used in drilling for oil or gas, and 730610 Line pipe of a kind used for oil or gas pipelines, as well as in the automotive, construction, and machinery sectors.
