Import Tips
• Verify that each copper foil layer is 35 µm (0.035 mm), well under the 0.15 mm maximum, and document this for the CBSA
• Ensure the FR4 backing is clearly identified as the substrate material in the commercial invoice
• If the panels are imported with pre-drilled holes or etched patterns, check whether they are still classifiable as foil
