CSAV's website lists an office in Tehran listed under the White Sea Star Shipping Services Co. Ltd. (CSAV Website).
CSAV is a Chilean shipping company that merged with German company Hapag-Lloyd (AG) in 2014 (Wall Street Journal, "Hapag-Lloyd-CSAV Complete Shipping Merger, 4/16/2014).
"In May 2013, CSAV of Chile suspended calls to Bandar Abbas on on its Galex Sling 1 service. This follows CSAV’s August 2012 decision to suspend booking acceptance from Europe to Iran with immediate effect.” In a June 10 letter sent to UANI by lawyers on behalf of CSAV, South America's largest shipping line confirmed that "CSAV... already decided to cease operations by CSAV owned, operated, or chartered Vessels to Iran ports." The letter went on to say that the company "may revisit this decision based on changes or clarifications of the scope of U.S. sanctions...."
