HS v2017 Code: 730439

About iron or non-alloy steel (excluding cast iron); seamless, (excluding cold-drawn or cold-rolled), tubes, pipes and hollow profiles of circular cross-section

HS code 730439 covers the import and export of seamless, non-cold-drawn or non-cold-rolled iron or non-alloy steel tubes, pipes, and hollow profiles of circular cross-section. This industry plays a crucial role in the global construction, manufacturing, and energy sectors, providing essential components for a wide range of applications, from oil and gas pipelines to structural supports and industrial equipment.

Production process

The production of the products covered by HS code 730439 typically involves a multi-step process. First, the raw materials, such as iron or non-alloy steel, are melted and cast into billets or ingots. These are then heated and passed through a series of rolling mills to create the desired seamless tube or pipe shape. The final products may undergo additional finishing processes, such as heat treatment or surface coating, to enhance their properties and performance.

Production inputs

The main inputs required for the production of the goods under HS code 730439 include iron or non-alloy steel, as well as specialized machinery and equipment for the rolling, forming, and finishing processes. Energy sources, such as electricity or natural gas, are also essential for the various production stages. Additionally, skilled labor and technical expertise are necessary to ensure the quality and consistency of the final products.

Production outputs

The seamless, non-cold-drawn or non-cold-rolled iron or non-alloy steel tubes, pipes, and hollow profiles produced under HS code 730439 are widely used in a variety of industries. They are often consumed by manufacturers of 730411 Iron or non-alloy steel; line pipe of a kind used for oil or gas pipelines, 730421 Iron or non-alloy steel; casing, tubing and drill pipe, of a kind used in drilling for oil or gas, and 730429 Iron or non-alloy steel; casing, tubing and drill pipe, of a kind used in drilling for oil or gas, other than seamless, as well as in the construction of buildings, infrastructure, and industrial equipment.
