1. Background:

The Maritime Transportation Security Act of 2002 (MTSA) requires the U.S. Coast Guard evaluate the effectiveness of antiterrorism measures in commercial foreign ports.

The Coast Guard has determined that Haiti is not maintaining effective antiterrorism measures in its ports. Actions required as listed in paragraphs C and D of this Port Security Advisory take effect for all commercial vessels that arrive in the United States on or after June 22, 2026, after visiting all ports in Haiti as one of their last five ports of call.

   • Provided by the vessel’s crew, however, additional crewmembers should be placed on the vessel if necessary to ensure that limits on maximum hours of work are not exceeded and/or minimum hours of rest are met, or
   • Provided by outside security forces approved by the vessel’s master and Company Security Officer.

1. Attempt to execute a Declaration of Security;

1. Actions Required by Vessels in U.S. Ports:

Based on the findings of the Coast Guard boarding or examination, the vessels that visited the countries listed in paragraph B (with exceptions noted) on or after the effective date in paragraph A may be required to ensure that each access point to the vessel is guarded by armed security guards and that they have total visibility of the exterior (both landside and waterside) of the vessel while in U.S. ports. The number and location of the guards must be acceptable to the cognizant U.S. Coast Guard Captain of the Port. For those vessels that have demonstrated good security compliance and can document that they took the measures called for in C.1. through C.4. above, the armed security guard requirement will normally be waived.
