Iron or steel (excluding cast iron); tubes, pipes and hollow profiles (not seamless), n.e.c. in chapter 73

HS v2017 Code: 730690

About iron or steel (excluding cast iron); tubes, pipes and hollow profiles (not seamless), n.e.c. in chapter 73

HS code 730690 covers a wide range of iron or steel tubes, pipes, and hollow profiles that are not seamless. These products are essential components in various industries, including construction, manufacturing, and infrastructure development. They are used in applications such as plumbing, HVAC systems, transportation, and industrial equipment. The global demand for these products is driven by factors such as urbanization, infrastructure investments, and the need for efficient and reliable distribution of fluids and gases.

Production process

The production of iron or steel tubes, pipes, and hollow profiles (not seamless) typically involves several key steps. First, the raw materials, which may include steel billets, sheets, or coils, are cut and formed into the desired shape and size. This can be done through processes like rolling, drawing, or extrusion. The formed products are then subjected to various heat treatments, such as annealing or tempering, to enhance their mechanical properties. Finally, the tubes, pipes, or hollow profiles may undergo additional finishing processes, such as coating or painting, to improve their corrosion resistance and aesthetic appeal.

Production inputs

The main inputs required for the production of HS code 730690 products include steel or iron raw materials, such as 720810 Hot-rolled flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, 720711 Semi-finished products of iron or non-alloy steel, and 720720 Bars and rods, hot-rolled, in irregularly wound coils, of iron or non-alloy steel. Additionally, specialized machinery and equipment, such as rolling mills, drawing machines, and heat treatment furnaces, are essential for the manufacturing process. Energy sources, such as electricity or natural gas, and skilled labor are also important inputs.

Production outputs

The main outputs of HS code 730690 are various types of iron or steel tubes, pipes, and hollow profiles that are not seamless. These products can be used in a wide range of applications, including 730410 Line pipe of a kind used for oil or gas pipelines, 730420 Casing, tubing and drill pipe, of a kind used in the drilling for oil or gas, and 730431 Tubes, pipes and hollow profiles, seamless, of circular cross-section, of iron or non-alloy steel. The outputs of HS code 730690 can also be used as inputs for other industries, such as construction, transportation, and machinery manufacturing.
