On September 30, 2010, aluminum powder from North Korea that could be used to make solid propellant for missiles was seized on a ship in Singapore harbor. This aluminum powder is controlled by the Missile Technology Control Regime (MTCR) because its particle size, weight, shape and aluminum content makes it suitable for the production of missile fuel; Iran is barred from importing MTCR-controlled items. The ship, the STX Patraikos, was en route to Bandar Abbas, Iran from Ningbo, China when it was stopped by Singaporean authorities. The shipper was Zhejiang Bainianyin Industry & Trade Co., Ltd., and the listed consignee was Takin Tejarat Omid Iranian.
