Import Tips
• Confirm the surface capping agents do not constitute organic compounds that would change classification under Chapter 28 notes
• Provide particle size distribution and purity data to the CBSA
• Check if nanomaterials trigger additional reporting under Canada's New Substances Notification Regulations
