Import Tips & Compliance
• Ensure the mixture's label and documentation specify HFC-23 content and absence of CFCs/HCFCs for classification under 3827.59.00
• Confirm the product is not a separate chemically defined compound, as that would shift classification to Chapter 29
• Keep the product's technical data sheet available for CBSA inspection
