Hollow Copper Square Profiles for Electrical Busbars from Japan
Extruded square hollow profiles of refined copper used in high-current electrical busbar systems, featuring thin walls for weight reduction while maintaining conductivity. Classified under HTS 7407.10.15.00 due to their hollow profile form of refined copper, not qualifying as bars or rods. The design allows internal cooling channels for electrical applications.

Import Tips
• Conductivity test certificates proving >99.9% pure refined copper help maintain 7407.10 classification over alloy headings
• Avoid bundling with fittings that could trigger 'articles of copper' classification under 7419
• Declare exact wall thickness and dimensions to distinguish from thin-walled copper tube under 7411
