On December 8, 2010, South Korean officials seized some 300 phosphor bronze wire mesh rolls with potential nuclear uses from a Korean Air Cargo jet at Seoul International Airport. The measurements of these rolls correspond to use in a water distillation column for heavy water production. The mesh rolls arrived from China and were bound for Pentane Chemistry Industries (PCI) in Iran following transshipment in Turkey. The shipment violates several U.N Security Council resolutions that bar Iran from importing items that could contribute to its heavy water-related capability.
