Security at the Port
We are committed to protecting the safety of our people and facilities, and support programs that protect our surrounding community.
We work proactively with federal, state and local officials to harden the security of our facilities. In partnership with the Port of Seattle, we have led federal efforts to strengthen the security of the international supply chain.
Transportation Worker Identification Credential
Entry to restricted areas of the Port of Tacoma requires a Transportation Worker Identification Credential (TWIC). All Port employees, terminal operators, longshore workers, merchant mariners, truckers and others who require regular, unescorted access to restricted Port areas and vessels are required to carry a TWIC.
TWIC holders can escort non-TWIC holders in restricted areas. Learn more about TWIC and Port of Tacoma escort services.
MARSEC Security Levels
Maritime security levels (the current level is indicated at the top of this page) are directly related to the potential terrorist activity. In response to potential attacks, the Port uses the three-tier system utilized by the U.S. Coast Guard. MARSEC Security Levels align with the five-level system used by the U.S. Department of Homeland Security.
The Department of Homeland Security (DHS) issues advisories through the Homeland Security Advisory System. Visit the DHS and U.S. Coast Guard websites for more information on security levels.
Note: Upon entry to a Restricted Area, the current MARSEC LEVEL will be posted.
