American Samoa Port Regions
American Samoa operates as a single concentrated maritime cluster rather than a multi-region port system. The groupings below describe the practical geography and the two indexed records without adding ports outside the supplied database sample.
Pago Pago Harbor
Pago Pago Harbor is the territory's principal commercial maritime area and the key reference point for ocean freight routing.
Pago Pago Harbor records
| Port | UN-LOCODE | City / Province | Main cargo role |
|---|---|---|---|
| Pago Pago | ASPGO | American Samoa / — | Primary commercial port reference |
Tutuila Island Logistics Cluster
Tutuila contains the main population, distribution and cargo-handling concentration of American Samoa, with activity generally routed through the Pago Pago area.
Tutuila-linked indexed records
| Port | UN-LOCODE | City / Province | Main cargo role |

American Samoa Port Codes
UN/LOCODEs identify transport locations and help carriers, forwarders and customs systems align port data. The following records use the AS country prefix.
City-Level and Terminal-Level Records
Two records may refer to different operational or geographic interpretations of the same Pago Pago area. A port-level code should therefore be checked against the booking, bill of lading and carrier instructions.
How to Verify a Port Code
Compare the code with the UNECE UN/LOCODE framework and cross-check the current Ecer Freight port directory before preparing shipping documents.
Shipping from American Samoa: Main Trade Lanes
American Samoa's ocean freight is generally organized around Pacific regional connections, with schedules, transshipment points and transit times subject to carrier confirmation.
American Samoa to the United States
Regularly planned cargo movements may connect Pago Pago with United States markets through carrier-operated Pacific services and transshipment arrangements.
American Samoa to Australia and New Zealand
Pacific regional services can support movement of commercial cargo toward Australia and New Zealand, usually with schedule-dependent connections.
American Samoa to Pacific Islands
Inter-island and wider Pacific cargo flows are generally smaller-volume services that depend on vessel availability and regional schedules.
Asia-Pacific Supply Chain Connections
Imported consumer, industrial and project cargo may move through broader Asia-Pacific networks before reaching Pago Pago, depending on the carrier's service design.
Data Sources and Methodology
Port coverage, code presentation and operating indicators use separate data concepts. Indexed coverage is based on the Ecer Freight database, while official operating statistics are reported only where a reliable public figure is available.

- UNECE — international UN/LOCODE structure and location-code reference framework.
- National Geospatial-Intelligence Agency — maritime geographic and port reference material.
- American Samoa Government — official territory-level government information and public statistical context.
- U.S. Maritime Administration — broader United States maritime and port-sector reference context.
