Import Tips
• >- Provide technical documentation showing the polyimide polymer composition and the foam's high-temperature properties
• Ensure the sheets are declared as cellular, not solid, to avoid classification under a different subheading
• If used in aerospace applications, verify compliance with Canadian aviation safety regulations
