Import Tips & Compliance

• Obtain a CNSC import permit prior to shipment, as uranium dioxide is a controlled nuclear substance

• Provide a certificate of analysis confirming UO2 purity and isotopic composition for customs clearance

• Check if the powder is subject to IAEA safeguards reporting requirements
