HS Code for Nickel tube

Nickel tubes are classified under HS code 7507.11 based on their material composition and physical form. According to the Harmonized System, Chapter 75 covers nickel and articles thereof. Heading 7507 specifically addresses tubes, pipes, and tube or pipe fittings. The subheading 7507.11 is reserved for tubes and pipes made of non-alloyed nickel. To qualify as "not alloyed," the metal must contain at least 99% nickel plus cobalt by weight, provided that the cobalt content does not exceed 1.5% by weight, and other elements do not exceed specific limits defined in the Chapter 75 notes. These products are typically manufactured through processes such as extrusion or drawing and must have a uniform wall thickness and a single closed void along their entire length. They are used in chemical plants, heat exchangers, and aerospace applications where corrosion resistance is paramount. The classification depends strictly on the chemical purity of the nickel and the geometric consistency of the product as a hollow profile.

Products Included

• Seamless non-alloyed nickel tubes
• Welded non-alloyed nickel pipes
• Pure nickel hollow bars used for fluid transport
• Non-alloyed nickel tubing for heat exchangers

Common Misclassification

A frequent error involves confusing 7507.11 with 7507.12, which covers tubes and pipes made of nickel alloys. The distinction rests entirely on the chemical composition; if the nickel content is less than 99% or if any other element exceeds the limits set in Note 1(b) to Chapter 75, the product must be moved to 7507.12. Additionally, importers often mistakenly look at heading 7304 or 7306, which cover iron or steel tubes. While these may look similar, the base metal takes precedence in the HS hierarchy. Another common mistake is classifying tube fittings under 7507.11; however, fittings such as elbows, sleeves, or flanges are specifically assigned to 7507.20, regardless of whether they are alloyed or not.

FAQ

What is the HS code for Nickel tube?

The HS code for non-alloyed nickel tubes and pipes is 7507.11.

Does 7507.11 include nickel alloy tubes?
