HS Code for Flexible metal tubing

Flexible metal tubing made from base metals other than iron or steel is classified under HS code 8307.90. Chapter 83 encompasses miscellaneous articles of base metal. Heading 8307 specifically covers flexible tubing of base metal, with or without fittings. The classification is divided based on the material composition of the tubing. While 8307.10 is dedicated to iron or steel, 8307.90 serves as the category for tubing made from other base metals such as aluminum, copper, brass, or bronze. These products are characterized by their ability to bend or flex, often constructed from spirally wound strips or corrugated walls. They are used in various industrial, plumbing, and electrical applications where rigid piping is unsuitable due to vibration, movement, or space constraints. The presence of fittings (such as nuts, sleeves, or connectors) does not change the classification, as heading 8307 explicitly includes tubing with or without fittings. This code is vital for ensuring the correct duty rates are applied based on the specific non-ferrous metal used in the manufacturing process.

Products Included

• Flexible aluminum conduits for electrical wiring
• Brass flexible shower hoses (metal component)
• Copper flexible gas connectors
• Bronze corrugated flexible pipes
• Flexible tubing made of nickel or tin
• Non-ferrous metal bellows for exhaust systems

Common Misclassification

Flexible metal tubing is often misclassified under 8307.10 if the user fails to identify that the metal is non-ferrous (not iron or steel). It is also sometimes confused with HS code 3917, which is strictly for plastic tubing. If the tubing is reinforced with rubber, it may be misclassified under 4009, but if the essential character is the metal structure, 8307 remains correct.

FAQ

What is the HS code for flexible metal tubing?
