The United States has maintained heightened port security restrictions on 10 African nations, including The Gambia, while removing Nigeria from the list of affected countries. The US Coast Guard determined that Nigeria's ports are now maintaining effective security measures, leading to its exemption from the additional procedures. This decision creates a clear divide within Africa's maritime sector, with Nigerian ports judged compliant and vessels linked to the ten remaining African countries facing additional security procedures.
Vessels arriving in US ports from The Gambia, Madagascar, Cameroon, Seychelles, Equatorial Guinea, Sudan, Guinea-Bissau, Libya, Comoros, and São Tomé and Príncipe continue to face enhanced security protocols. In contrast, Nigerian ports are now judged compliant with international security standards. The removal signifies that vessels linked to the remaining ten African countries will continue to undergo additional security procedures upon arrival in the United States. These measures are a critical component of the US Coast Guard’s ongoing efforts to safeguard maritime trade routes and national security.
Restricted African Nations Detailed
The list of African nations facing continued heightened scrutiny includes Madagascar, Cameroon, Seychelles, Equatorial Guinea, Sudan, Guinea-Bissau, Libya, Comoros, and São Tomé and Príncipe, in addition to The Gambia. Vessels arriving in United States ports from these 10 countries are subject to enhanced security procedures. The decision to maintain these restrictions is part of an ongoing effort to ensure maritime security standards are met globally. These countries have been identified as not maintaining effective antiterrorism measures in their port facilities, necessitating the additional scrutiny.
A new advisory has been issued, replacing Port Security Advisory 3-26. This updated guidance formalizes the extension of heightened scrutiny to shipping originating from or having called at ports in the 10 specified African nations. The measure mandates that vessels arriving in the U.S. From these countries undergo additional security checks, reflecting the US Coast Guard's assessment of their port security measures. These procedures are intended to mitigate potential security risks associated with maritime trade routes and protect US ports from potential threats.
US Coast Guard Advisory Explained
The US Coast Guard, in its August 19, 2026 Port Security Advisory, determined that ports in the specified countries were "not maintaining effective antiterrorism measures." This advisory operates under the US Maritime Transportation Security Act of 2002. Where port security standards are deemed inadequate, the United States reserves the right to impose additional conditions on vessels arriving from those locations. This legal framework provides the authority for the US Coast Guard to implement and enforce these critical security protocols.
Vessels that have previously called at ports in the affected countries are mandated to implement extra security measures and report their compliance before entering US ports. These vessels must implement measures equivalent to Security Level 2 while within the affected country's jurisdiction. They are required to guard every access point to the vessel, attempt to execute a Declaration of Security, record all security measures undertaken, and report these actions to the relevant US Coast Guard Captain of the Port prior to arriving in the United States. This full set of requirements aims to ensure a strong security posture throughout the voyage.
The US Coast Guard retains the authority to board or examine vessels to verify compliance with these regulations. This oversight mechanism ensures that shipping operators are adhering to the prescribed security protocols. Failure to implement the required measures could lead to delayed or denied entry into US ports, showing the seriousness of these mandates. For vessels arriving in US ports after visiting one of the affected countries, the Coast Guard can mandate armed security guards at vessel access points, though this requirement can typically be waived if ships demonstrate strong security compliance and provide documentation proving the prescribed measures were implemented. This provision offers flexibility while maintaining a high level of security.
Broader Maritime Security Context
Currently, 22 countries remain on the US Coast Guard’s port security advisory list, which includes the ten African nations recently noted. This broader list reflects ongoing global efforts to maintain international maritime security standards and address potential vulnerabilities in the global supply chain. The inclusion of these countries mandates specific security protocols for vessels that have called at their ports before arriving in the United States, thereby extending the security perimeter beyond US territorial waters.
For shipping operators, these heightened security measures introduce significant operational challenges. Additional inspections, the requirement for security personnel, and extensive documentation can increase the complexity of international voyages. The potential for delays at US ports due to these enhanced checks contributes to higher operational costs for shipping lines. These stipulations aim to mitigate security risks in global shipping lanes, but they also place a substantial burden on the maritime industry, requiring careful planning and adherence to detailed security procedures to ensure smooth operations.
