High-Purity Cu Rectangle Extrusion from China
A high-purity refined copper rectangular profile, extruded to a solid rectangular cross-section with tight dimensional tolerances, intended for use in semiconductor heat sinks and precision components. It qualifies as a bar or profile of refined copper under tariff item 7407.10.90 because it is not a hollow profile and is not further worked beyond extrusion.

Import Tips
• Ensure the copper purity is documented (e.g
• 99.99%) to support classification as refined copper under Chapter 74
• Verify the cross-section is solid and rectangular, as hollow profiles fall under a different tariff item
• Keep mill test certificates available for CBSA inspection
