Hollow Copper-Nickel Profile for Heat Exchangers from United States
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.

Import Tips
• 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
