Hollow Copper D-Shaped Profiles for Solar Thermal Collectors from China
D-shaped hollow profiles of refined copper designed for solar thermal absorber plates, where the flat side bonds to aluminum fins and the curved hollow carries heat transfer fluid. Under HTS 7407.10.15.00 as hollow profiles of refined copper, valued for corrosion resistance and thermal properties. The unique cross-section distinguishes them from standard tubing.

Import Tips
• Include solar thermal end-use certification to support profile vs tube classification debate
• Ensure packaging labels profiles distinctly from copper pipe to prevent 7411 reclassification
• Conduct XRF analysis documentation for copper purity if challenged on refined status
