Iron or non-alloy steel (excluding cast iron); tubes and pipes (not seamless), welded, of circular cross-section, n.e.c. in chapter 73

HS v2017 Code: 730630

About iron or non-alloy steel (excluding cast iron); tubes and pipes (not seamless), welded, of circular cross-section, n.e.c. in chapter 73

HS code 730630 covers a critical component of the global steel industry - welded iron or non-alloy steel tubes and pipes of circular cross-section. These products are widely used in a variety of applications, including construction, manufacturing, and infrastructure development. They play a vital role in the broader economy, facilitating the transportation of fluids, gases, and other materials across diverse sectors.

Production process

The production of welded steel tubes and pipes under HS code 730630 typically involves a multi-step process. First, steel coils or sheets are cut and formed into a cylindrical shape. The edges are then welded together using techniques such as electric resistance welding or laser welding. The welded tubes may undergo additional processing, such as heat treatment or surface finishing, to enhance their properties and meet specific requirements.

Production inputs

The main inputs required for the production of 730630 products include steel raw materials, such as 720839 hot-rolled steel coils or sheets, as well as specialized welding equipment and machinery. Energy sources, such as electricity or natural gas, are also essential for the manufacturing process. Additionally, skilled labor and technical expertise are necessary to ensure the quality and consistency of the final products.

Production outputs

The primary outputs of HS code 730630 are welded steel tubes and pipes of circular cross-section, which are used in a wide range of applications. These products may be further processed or incorporated into larger assemblies, such as 730900 reservoirs, tanks, vats, and similar containers, 731010 tanks, casks, drums, cans, boxes, and similar containers, or 730900 structures and parts of structures. The 730630 products are also consumed by industries that require the transportation of fluids, gases, or other materials, including 841810 refrigerators, household-type, 841919 instantaneous or storage water heaters, and 842123 machinery and apparatus for filtering or purifying gases.
