HS Code for Nickel tube fittings

Nickel tube fittings are classified under HS code 7507.20. This classification is appropriate for products where nickel is the predominant metal by weight, placing them in Chapter 75. Heading 7507 covers nickel tubes, pipes, and their associated fittings. While subheadings 7507.11 and 7507.12 are reserved for the tubes and pipes themselves, 7507.20 is the specific code for tube or pipe fittings, such as couplings, elbows, and sleeves. These components are essential for changing the direction, diameter, or termination of a piping system. The classification applies to both pure nickel fittings and nickel alloy fittings (such as Monel or Inconel), provided the nickel content is greater than any other single element.

Products Included

• Nickel alloy elbows for chemical processing plants
• Monel pipe couplings for marine environments
• Nickel-based threaded tees for high-temperature applications
• Nickel alloy reducers and flanges
• Inconel sleeves for aerospace fluid systems

Common Misclassification

Nickel tube fittings are frequently misclassified under 7307, which covers iron or steel fittings, especially when the alloy contains iron. However, if the nickel content is higher than the iron content, Chapter 75 takes precedence. They may also be confused with 7412.20 (copper alloy fittings) if the alloy is actually nickel silver or cupro-nickel, which are copper-based.

FAQ

What is the HS code for nickel tube fittings?

The HS code for nickel and nickel alloy tube or pipe fittings is 7507.20.

Are stainless steel fittings classified here?

No, stainless steel fittings are classified under heading 7307. Code 7507.20 is strictly for fittings where nickel is the primary constituent by weight.
