Import Tips
• Ensure the product's composition is clearly documented, as the 40% HFC-125 threshold determines the classification
• Verify whether the blend is subject to Canada's ozone-depleting substances and HFC regulations, which may require permits
• Declare the exact mass percentage of HFC-125 on customs documents to avoid reclassification
