HS v2017 Code: 730723

About steel, stainless; tube or pipe fittings, butt welding fittings

HS code 730723 covers the trade of stainless steel tube or pipe fittings, specifically those used for butt welding. This industry plays a crucial role in the broader manufacturing and construction sectors, providing essential components for a wide range of applications. Stainless steel fittings are valued for their durability, corrosion resistance, and ability to withstand high temperatures and pressures, making them indispensable in industries such as 841989 Machinery for the treatment of materials by a process involving a change of temperature, 870000 Vehicles other than railway or tramway rolling-stock, and parts and accessories thereof, and 732000 (Reservoirs, tanks, vats and similar containers, for any material (other than compressed or liquefied gas), of iron or steel, of a capacity exceeding 300 l, whether or not lined or heat-insulated, but not fitted with mechanical or thermal equipment).

Production process

The production of stainless steel tube or pipe fittings, butt welding fittings (HS 730723) typically involves a multi-step process. First, the raw stainless steel material is sourced and cut to the desired size and shape. The pieces are then carefully aligned and joined using a butt welding technique, which creates a strong, seamless connection. Finally, the fittings undergo various finishing processes, such as polishing, to ensure a high-quality, durable product.

Production inputs

The main inputs required for the production of stainless steel tube or pipe fittings, butt welding fittings (HS 730723) include high-quality stainless steel raw materials, specialized welding equipment, and various finishing tools and machinery. Additionally, skilled labor, energy resources, and a reliable supply chain are essential for the efficient and consistent production of these critical components.

Production outputs

The primary output of HS code 730723 is stainless steel tube or pipe fittings, specifically those designed for butt welding. These fittings are then consumed by a wide range of industries, including 841989 Machinery for the treatment of materials by a process involving a change of temperature, 870000 Vehicles other than railway or tramway rolling-stock, and parts and accessories thereof, and 732000 (Reservoirs, tanks, vats and similar containers, for any material (other than compressed or liquefied gas), of iron or steel, of a capacity exceeding 300 l, whether or not lined or heat-insulated, but not fitted with mechanical or thermal equipment), where they are used to connect and join various piping and tubing systems.
