The sanctions imposed on the Iranian port's operators and shipping lines during the period of year 2012 to 2018 were huge challenges for Iranian seaports and maritime trades. Its impact on container business was instantaneous and port throughput shrank by 38 percent. In order to evaluate the Iranian port's performance and their relative efficiency during the sanction period, 10-year data had been collected for five container ports of Iran. This set of data was then analyzed by using Data Envelopment Analysis (DEA). All ports had shown decreased port average efficiency after imposed sanction. Then four ports namely Khorramshahr (from 0.73 to 0.51), Bushehr (from 0.78 to 0.83), Bandar Imam Khomeni (from 0.27 to 0.33) and Chabahar (slight increase) had shown increased port average efficiency only one port namely Shahid Rajaei (from0.89 to .083).
