As a vital part of Guam's economic infrastructure, the Port Authority handles more than 90 percent of the island's total imports. The United States provides some 60 percent of Guam's imported goods, with the balance of Guam's trade coming from the Asian and Pacific markets of Japan, Taiwan, the Philippines, Hong Kong, and – to a lesser extent – Australia, New Zealand, and the islands of Micronesia.

In addition to handling Guam's imports and exports, the Port of Guam also offers efficient and economical transshipment services from the United States, Hawaii, and Far East to the entire western Pacific. With American vessels leaving the Port weekly for the U.S. West coast, there are virtually no delays in cargo to the Mainland.

As a United States territory, Guam falls under American law, and its port operations follow the same rules and regulations governing other U.S. ports. Under the jurisdiction of the United States Coast Guard, the events of 9/11 changed security requirements for all aspects of transportation. The International Ship and Port Security (ISPS) Codes implemented by the United Nations served as the model for forming the Maritime Transportation Security Act (MTSA) of 2001. The local regulatory agency, Guam Customs and Quarantine, enforces all local and federal regulations on imports and exports at Guam's port of entries.

The Port of Guam is fully equipped to handle all types of cargo: containerized, breakbulk, unitized, as well as fishery. During Fiscal Year 2008, more than 2 million cargo revenue tons – of which a majority was containerized – passed through the Port's docks. This translates to 99,908 containers handled by our facility.
