About valves and tubes; n.e.c. in heading no. 8540

HS code 854089 covers a wide range of valves, tubes, and other devices that are not classified elsewhere in the 8540 heading. These components play a crucial role in various industries, including manufacturing, transportation, and infrastructure. They are essential for regulating and controlling the flow of fluids, gases, and other materials, making them indispensable in applications such as plumbing, HVAC systems, and industrial machinery.

Production process

The production of valves and tubes under HS code 854089 typically involves a combination of metalworking, machining, and assembly processes. Manufacturers may use techniques like casting, forging, or stamping to shape the basic components, followed by precision machining to ensure accurate dimensions and tolerances. Assembly may involve welding, brazing, or other joining methods to integrate the various parts, such as the body, stem, and sealing elements.

Production inputs

The main inputs required for the production of valves and tubes under HS code 854089 include metals, such as steel, brass, or aluminum, as well as specialized components like seals, springs, and actuators. Manufacturers may also rely on various tools, machinery, and equipment, such as lathes, milling machines, and welding equipment, to facilitate the production process. Additionally, the industry may utilize specialized software and control systems to ensure precise manufacturing and quality control.

Production outputs

The primary outputs of the industry covered by HS code 854089 are the valves, tubes, and related devices themselves. These components are then consumed by a wide range of other industries, including 842139 Filtering or purifying machinery and apparatus for gases, 841430 Compressors of a kind used in refrigerating equipment, and 842119 Filtering or purifying machinery and apparatus for liquids.
