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 welded iron or steel tubes, pipes, and hollow profiles with 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 by HS code 730661 typically involves a welding process. Steel or iron sheets or strips are cut to the desired size and shape, then formed into a square or rectangular cross-section. The edges are then welded together, creating a seamless, hollow profile. This process can be carried out using various welding techniques, such as arc welding, resistance welding, or laser welding, depending on the specific requirements of the product.
Production inputs
The main inputs required for the production of the products covered by HS code 730661 include steel or iron raw materials, such as sheets or strips, as well as welding equipment and consumables. Depending on the specific application, additional inputs may include coatings or surface treatments to enhance the product's durability and performance. The availability and cost of these raw materials and production equipment can significantly impact the industry's overall competitiveness.
Production outputs
The products covered by HS code 730661 are primarily used as structural components, piping, and other industrial applications. They may be further processed or incorporated into a wide range of finished goods, such as 730120 Iron or steel; angles, shapes and sections, not further worked than hot-rolled, hot-drawn or extruded, 730300 Cast iron; tubes, pipes and hollow profiles, or 730410 (Iron or steel (excluding cast iron); tubes, pipes and hollow profiles, seamless, of a kind used for oil or gas pipelines). The demand for these products is closely tied to the performance of the construction, manufacturing, and infrastructure sectors.
