HS v2017 Code: 8307
About tubing; flexible, with or without fittings, of base metal
hs code 8307 covers the import and export of flexible tubing made from base metals, with or without fittings. This type of tubing is widely used across a variety of industries, including automotive, plumbing, and industrial machinery. Its versatility and durability make it an essential component in many manufacturing and infrastructure applications, contributing to the overall efficiency and functionality of diverse products and systems.
Production process
The production of flexible base metal tubing involves several key steps. First, the raw materials, such as steel, copper, or aluminum, are melted and extruded into the desired tube shape. The tubing is then subjected to various forming and shaping processes, which may include bending, coiling, or the addition of fittings, depending on the intended application. Quality control measures, such as testing for strength, flexibility, and corrosion resistance, are implemented throughout the manufacturing process to ensure the final product meets industry standards.
Production inputs
The main inputs required for the production of flexible base metal tubing include the raw metal materials, such as 7207 Steel in primary forms, 7401 Copper, unrefined; copper anodes for electrolytic refining, or 7601 Aluminum, unwrought. Additionally, specialized machinery and equipment, such as extruders, benders, and welding tools, are necessary for the various shaping and assembly processes. Skilled labor, with expertise in metalworking and quality control, is also a critical input for this industry.
Production outputs
The primary output of hs code 8307 is flexible tubing made from base metals, which can be used in a wide range of applications. This tubing may be further incorporated into other products, such as 8708 Parts and accessories of motor vehicles, 8481 Taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like, or 8415 Air conditioning machines, among others. The versatility of this tubing makes it an essential component in many industries, contributing to the overall functionality and efficiency of various systems and products.
