HS v2022 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 industry plays a crucial role in various sectors, including construction, automotive, and industrial equipment manufacturing. Flexible metal tubing is valued for its durability, versatility, and ability to withstand high pressure and temperature conditions, making it an essential component in a wide range of applications.

Production process

The production of flexible metal tubing typically involves a multi-step process. First, the base metal, such as steel, copper, or aluminum, is formed into a thin, continuous strip. This strip is then passed through a series of rollers and dies to shape it into a tubular form. The tubing may undergo additional processes, such as annealing or galvanizing, to enhance its properties and performance. Finally, fittings such as connectors or adapters may be attached to the tubing, depending on the intended use.

Production inputs

The main inputs required for the production of flexible metal tubing include the base metal raw materials, such as 7208 Flat-rolled products of iron or non-alloy steel, 7409 Copper plates, sheets and strip, or 7601 Unwrought aluminum. Additionally, specialized machinery and equipment, such as rolling mills, welding machines, and cutting tools, are essential for the manufacturing process. Energy sources, such as electricity or natural gas, are also necessary to power the production facilities.

Production outputs

The primary output of HS code 8307 is flexible metal tubing, which is used in a variety of applications. This tubing may be consumed by industries such as 8708 Parts and accessories of motor vehicles, 8415 Air conditioning machines, and 8481 Taps, cocks, valves and similar appliances, where it is used for fluid or gas transportation, cooling systems, and various industrial equipment. The versatility of flexible metal tubing makes it a valuable component in many sectors of the economy.
