Hollow Copper Oval Profiles for Radiator Manufacturing
Oval-shaped hollow profiles extruded from refined copper, engineered for automotive and industrial radiator cores where the elongated cross-section optimizes fluid flow and heat dissipation. HTS 7407.10.15.00 applies to these refined copper hollow profiles, separate from circular tubing. Their precise wall thickness supports brazing in heat exchanger assemblies.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as other copper tubes due to thin walls and fluid handling
Customs may reclassify thin-walled hollow profiles as tubes under 7411 if they function primarily for fluid transport.
If made from copper-tin base alloys (bronzes)
Bronze alloys per subheading note (b) with tin predominance classify under 7407.21 instead of refined copper.
If imported as parts of heat exchange units
Machinery parts of copper for heat exchangers fall under Chapter 84 specific end-use headings.

Import Tips & Compliance
• Mill test reports certifying refined copper chemistry (Cu >99.9%) are crucial to avoid alloy misclassification
• Specify 'profiles' not 'tubes' in commercial invoices; include cross-sectional diagrams showing non-circular hollow shape
• For radiator-specific imports, separate from fins or headers to prevent set classification under 8708.99
