Canada's nuclear import/export control list updated to align with latest IAEA non-proliferation standards

Plain-language summary · AI-assisted

The schedule listing controlled nuclear substances, equipment, and information under Canada's nuclear non-proliferation import and export rules has been substantially revised. The controlled-items lists are now aligned with newer IAEA reference circulars (updated revision numbers for all three source documents). Practically, this means the range of items requiring a licence to import or export has changed: several exemptions have been expanded (e.g., biological samples added to contamination exclusions; thorium in consumer goods like welding rods now exempt; small graphite and tritium shipments carved out), new items have been added to the controlled lists (e.g., rhenium alloys, pulsed carbon monoxide lasers, neutron sources based on specific alpha-emitting radionuclides, ammonia synthesis units for heavy water production), and numerous technical thresholds and definitions have been updated (e.g., centrifuge component diameter limits raised from 400 mm to 650 mm, maraging steel strength threshold lowered, pressure transducer criteria expanded). Businesses and researchers who import or export nuclear-related materials, equipment, or technical data should review the updated schedule carefully to determine whether items they trade in are newly controlled, newly exempt, or subject to revised technical thresholds.
