Import Tips
• HEMA used in medical devices may require Health Canada approval; ensure you have the necessary documentation before importing
• The product must be a pure chemically defined compound; any polymerization inhibitors must be within Chapter 29's allowable limits
• Keep safety data sheets available, as HEMA is a sensitizer and customs may request hazard documentation
