Specifically, the State Department accused IRISL that repeatedly transported items related to Iran’s ballistic missile and military programs and is also a longstanding carrier of other proliferation-sensitive items, including Nuclear Suppliers-Group controlled items.
In light of the above, the U.S. Secretary of State Mike Pompeo warned commercial and shipping industries, governments, and others that they will face U.S. sanctions, if they did business with the Islamic Republic of Iran Shipping Lines (IRISL) and its Shanghai-based subsidiary, E-Sail Shipping Company.
For the records, the State Department had announced the designations back in December 2019, but allowed a delay for them to take effect, giving time for exporters of humanitarian goods to Iran to find different shipping methods.
Now that this generous delay has come to an end, those in the commercial and maritime industries doing business with Iran must use carriers or shipping methods other than IRISL or E-Sail; any government, entity, or individual that chooses to continue doing business with IRISL and/or E-Sail now risks exposure to U.S. WMD sanctions.
