Import Tips & Compliance
• >- Provide documentation showing the panels are cellular (foamed) and made of polycarbonate, as CBSA may require proof of the polymer composition
• If the panels are multiwall (e.g
• with integral ribs), confirm whether they are considered cellular or structural, as this may affect classification
• Ensure the panels meet Canadian building code requirements if used in construction
