Import Tips
• Verify that the product is in primary form (liquid) and that the siloxane content exceeds 95% by weight to meet the subheading note requirements
• Provide a certificate of analysis to the CBSA showing the phenyl modification and polymer content
• Check if the product meets Canadian electrical safety standards if used in transformers
