Tubing; flexible, with or without fittings of base metal, other than those of iron or steel

hs code 830790 covers a wide range of flexible tubing and piping made from base metals, excluding those made of iron or steel. This type of tubing is essential for various industrial and commercial applications, including plumbing, HVAC systems, and chemical processing. The global market for flexible metal tubing has been growing steadily, driven by the increasing demand from end-use industries and the need for durable, corrosion-resistant piping solutions.

The production of flexible metal tubing under hs code 830790 typically involves a multi-step process. First, the base metal, such as copper, brass, or aluminum, is extruded or drawn into a thin, continuous tube. The tubing is then coiled and annealed to increase its flexibility. Depending on the application, the tubing may be further processed by adding fittings, coatings, or reinforcements to enhance its durability and functionality.

The main inputs required for the production of flexible metal tubing under hs code 830790 include base metal raw materials, such as copper, brass, or aluminum, as well as specialized machinery for extrusion, drawing, and coiling. Additionally, manufacturers may use various fittings, connectors, and coatings to customize the tubing for specific applications. Energy, labor, and transportation are also significant inputs in this industry.

The primary output of hs code 830790 is flexible metal tubing, which is used in a wide range of applications, including 842131 Pumps for liquids, whether or not fitted with a measuring device, 841430 Compressors of a kind used in refrigerating equipment, and 851440 Electric industrial and laboratory furnaces and ovens. This tubing is often consumed by industries such as plumbing, HVAC, automotive, and chemical processing, among others.
