Hollow Copper Rectangular Profiles for HVAC Systems from Japan
These are extruded hollow profiles made from refined copper, featuring a rectangular cross-section with a continuous hollow center, used primarily in heat exchanger assemblies for HVAC units. They fall under HTS 7407.10.15.00 as hollow profiles of refined copper, distinguished from solid profiles by their internal void designed for fluid flow. The refined copper composition ensures high thermal conductivity essential for heat transfer applications.

Import Tips
• Verify copper purity documentation to confirm 'refined copper' status, as electrolytic tough pitch (ETP) copper is standard for this classification
• Provide engineering drawings showing hollow cross-section to avoid misclassification as solid profiles under 7407.10.10.00
• Include end-use statements for HVAC to prevent reclassification as copper tube under 7411 if fluid-carrying intent is evident
