The Golsan, an Iranian merchant vessel, delivered supplies for an Iranian supermarket in Venezuela before refilling with 14 thousand metric tons of Venezuelan alumina, which is used to manufacture aluminum. The Golsan docked at a port belonging to CVG Bauxilum, a Venezuelan state-owned enterprise specializing in alumina. The Iranian company Mosakhar Darya Shipping Co. owns the Golsan, and the Iranian firm Rahbaran Omid Darya manages it. In November 2018, the United States sanctioned both companies, which share an address.
