Import Tips
• Secure a CNSC import permit, as curium-244 is a transuranic element subject to strict controls
• Document the specific radioactivity (Bq/g) of the alloy to demonstrate it exceeds the 74 Bq/g threshold for heading 28.44
• Ensure the alloy composition is clearly stated on the commercial invoice to avoid misclassification
