Hollow Copper-Nickel Profile for Heat Exchangers
Hollow rectangular profile made from a copper-nickel base alloy containing 1% or less zinc, designed for use in heat exchanger components. The nickel content predominates over other elements, classifying it as a copper-nickel base alloy under subheading note (d). Its hollow rectangular cross-section qualifies it as a profile under Chapter 74 definitions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the profile is made of refined copper, not a copper alloy
Refined copper profiles fall under a different subheading within the same heading.
If the profile has been further worked into a specific article, such as a finished heat exchanger part
Articles of copper, other than those covered by earlier headings, are classified under heading 74.19.

Import Tips & Compliance
• Ensure the alloy composition is documented, particularly zinc content (≤1%) and nickel predominance, to support classification under 7407.29.00
• Provide a mill certificate or lab analysis to CBSA upon request
• Verify if the profile is considered 'unworked' per supplementary note 1, as further processing may affect classification
