A five-week, multi-agency enforcement operation at Guam’s main seaport is now complete—strengthening border security and reinforcing partnerships aimed at keeping contraband off the island.

The Guam Customs and Quarantine Agency, working alongside local and federal partners, has concluded a customs-centered special enforcement operation at the Jose D. Leon Guerrero Commercial Port. The operation, led by Customs’ Special Enforcement Division, ran from late-October through late-November and focused on heightened border interdiction efforts. Officers conducted extensive container inspections and maritime vessel searches as part of the mission.

Customs activated multiple specialized units, including the Contraband Enforcement Team, Drug Detector Dog Unit, X-Ray Unit, and the Maritime Interdiction Task Force, all aimed at identifying potential threats and illegal imports.

In total, officers inspected eight maritime vessels, 30 vehicles, and 45 shipping containers. One broken container seal was discovered, and one arrest was made for an outstanding warrant during inspections at a satellite site. No drugs or contraband were found.

Customs officials say the operation strengthened coordination among partner agencies and highlighted the importance of continued vigilance at Guam’s ports of entry.

Officials emphasized that interdiction efforts will continue, underscoring a commitment to protecting public safety and upholding the rule of law.
