The U.S. marine transportation system continues to handle large volumes of domestic and international
freight in support of the nation's economic activities. The demand for freight transportation
responds to trends in global economic activity and merchandise trade. When U.S. businesses produce
more goods, the demand for freight transportation services to move raw materials and finished
products to markets and customers around the country and world will increase. When economic
conditions result in less production, the demand for transportation services will decrease.
This report provides an overview of the movement of maritime freight handled by the nation's container
seaports in 2008 and summarizes trends in maritime freight movement since 1995. It covers
the impact of the recent U.S. and global economic downturn on U.S. port container traffic, trends in
container throughput, concentration of containerized cargo at the top U.S. ports, regional shifts in
cargo handled, vessel calls and capacity in ports, the rankings of U.S. ports among the world's top
ports, and the number of maritime container entries into the United States relative to truck and rail
containers. The report also presents snapshots of landside access to container ports, port security
initiatives, and ongoing maritime environmental issues.
The principal findings of the report include the following:
- Maritime freight handled by U.S. container ports fell sharply towards the end of 2008, and the decline
continued into the first quarter of 2009. Total U.S. containerized cargo for December 2008
was down 18 percent compared with December 2007. The decline was severe at the nation's
two leading container ports, Los Angeles and Long Beach, which experienced 13 and 25 percent
- Overall in 2008, U.S. container ports handled 28.2 million loaded TEUs (20-foot equivalent
units-a measure for counting containers), a 3 percent drop from the 29 million TEUs handled in
- In 2008, containerized freight throughput fell for each of the leading ports in the Pacific/west
coast, Atlantic/east coast, and gulf coast regions. West coast ports had a 5 percent decline, east
coast ports a less than 1 percent decline, and gulf coast ports a 3 percent decline.
- The consequences of the 2008 decline in container throughput at the nation's seaports reached
beyond the marine ports and terminals, affecting containership fleet capacity, the railroads and
commercial trucks that service the seaports, and the inland warehouses and distribution centers
that provide logistical support for the entire multimodal freight supply chain.
- In 2008, the decline in maritime containerized cargo impacted international intermodal containers
handled by the nation's Class I railroads, which fell 7 percent from 2007. It also affected overall
trucking activity, which saw record declines in the second half of 2008.
- Despite the 2007 to 2008 declines, today 1 container in every 10 that is engaged in global trade
is either bound for or originates in the United States, accounting for 10 percent of worldwide
- On a typical day in 2008, U.S. container ports handled an average of 77,000 TEUs, up from
37,000 TEUs per day in 1995.
- In 2008, the top 10 U.S. container ports accounted for 86 percent of containerized TEU imports
and exports, up from 78 percent in 1995.
- In 2008, 3 U.S. ports-Los Angeles, Long Beach, and New York/New Jersey-ranked among the
world's top 20 container ports when measured by TEUs, placing 16th, 17th, and 20th, respectively.
- In 2007, there were nearly 20,000 containership calls at U.S. seaports, accounting for 31 percent
of the total oceangoing vessel calls made by all vessel types at U.S. ports.
- In 2007, there were about 12 million oceanborne container entries into the United States, down
slightly from 2006 but still double those of 2000.
- In April 2009, a U.S.-flagged container vessel with 20 American sailors was hijacked by pirates off
the coast of Somalia, highlighting the challenge of fully securing maritime cargo throughout the
entire global logistics supply chain.
