HS v2017 Code: 730661

About iron or steel (excluding cast iron); tubes, pipes and hollow profiles (not seamless), welded, of square or rectangular cross-section, n.e.c. in chapter 73

HS code 730661 covers a wide range of iron or steel tubes, pipes, and hollow profiles that are welded and have a square or rectangular cross-section. These products are essential components in various industries, including construction, manufacturing, and infrastructure development. They are used in applications such as structural supports, plumbing systems, and industrial equipment, making them a crucial part of the global economy.

Production process

The production of the products covered under HS code 730661 typically involves a multi-step welding process. First, steel sheets or strips are cut and formed into the desired square or rectangular shape. The edges of the formed pieces are then welded together using techniques such as arc welding or laser welding, creating a seamless, strong, and durable tube or pipe. The final products may undergo additional finishing processes, such as coating or painting, to enhance their durability and appearance.

Production inputs

The main inputs required for the production of the products under HS code 730661 include steel sheets or strips, welding equipment and consumables, and various tools and machinery for cutting, forming, and finishing the products. Additionally, energy sources, such as electricity or natural gas, are needed to power the welding and other production processes. The availability and cost of these raw materials and resources can significantly impact the overall production and competitiveness of this industry.

Production outputs

The products covered under HS code 730661 are widely used in a variety of industries, including 730120 Construction, 842139 Manufacturing, and 730820 Infrastructure development. These welded tubes, pipes, and hollow profiles are often consumed by industries that require structural support, piping systems, or other industrial applications. The outputs of this industry can be further processed or incorporated into a wide range of finished goods, making it an essential component of many supply chains.
