HS v2022 Code: 730459

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

HS code 730459 covers a crucial segment of the steel industry, focusing on the production of alloy steel tubes, pipes, and hollow profiles of circular cross-section. These products play a vital role in various industries, including construction, energy, transportation, and manufacturing, making them an essential component of the global economy.

Production process

The production of steel tubes and pipes under HS code 730459 typically involves a combination of casting, rolling, and welding techniques. Steel billets or slabs are first heated and then rolled or extruded into the desired shape and size. The resulting tubes or pipes may undergo further processing, such as heat treatment or surface finishing, to enhance their properties and meet specific industry requirements.

Production inputs

The key inputs for the production of steel tubes and pipes under HS code 730459 include alloy steel raw materials, such as 720221 Ferro-chromium, 720221 Ferro-manganese, and 720229 Ferro-alloys. Additionally, specialized machinery, such as rolling mills, welding equipment, and heat treatment furnaces, are essential for the manufacturing process. Energy sources, such as electricity and natural gas, are also crucial inputs for this industry.

Production outputs

The primary outputs of the industry covered by HS code 730459 are alloy steel tubes, pipes, and hollow profiles of circular cross-section. These products are widely used in various applications, including 730431 Line pipe of a kind used for oil or gas pipelines, 730441 Casing, tubing and drill pipe, of a kind used in drilling for oil or gas, and 730451 Other, of circular cross-section, of alloy steel. The outputs of this industry are often consumed by other industries, such as construction, energy, and manufacturing, making it an integral part of the global supply chain.
