HS Code for Flexible steel tubing

Flexible steel tubing is classified under HS code 8307.10, which falls within Chapter 83 of the Harmonized System, covering miscellaneous articles of base metal. Heading 8307 is specifically dedicated to flexible tubing of base metal, with or without fittings. The sub-classification 8307.10 is restricted to tubing made of iron or steel. This classification is determined by the flexible nature of the tube, which is often achieved through a spiral-wound, interlocked, or corrugated construction. Unlike rigid pipes found in Chapter 73, these products are designed to bend and flex without breaking, making them suitable for vibration dampening, thermal expansion compensation, or protecting electrical cables in tight spaces. The presence of fittings does not change the classification under this heading, as 8307 explicitly includes tubing with or without attachments. The material must be predominantly iron or steel; if the tubing is made of other base metals like aluminum or copper, it would fall under 8307.90. This code is vital for industrial suppliers of conduit and high-temperature exhaust connectors.

Products Included

• Interlocked flexible steel hoses
• Corrugated stainless steel tubing (CSST)
• Flexible steel conduit for electrical wiring
• Galvanized flexible steel tubes
• Stainless steel bellows-type flexible connectors

Common Misclassification

The most common misclassification occurs with Chapter 73 (specifically 7304, 7305, or 7306), which covers rigid iron or steel pipes. Flexible steel tubing is also sometimes confused with 8307.90, which is the category for flexible tubing made of metals other than iron or steel, such as aluminum or brass.
