Difficulties in Tantalum Raw Materials Transport – And What Can Be Done About It
This paper, presented by Ulric Schwela at an IAEA meeting, examines why transporting tantalum raw materials classified as radioactive remains a serious challenge. From denial of shipment to carrier refusals and regulatory inconsistencies, the piece outlines the industry’s workarounds and calls for harmonised international transport regulations to prevent illegal shipping practices and supply chain disruption.
