A new federal study out this month showed 2015 was the second consecutive year when seaports north and south of the United States saw larger growth in container shipments than did those this country.

Federal Maritime Commissioner Richard A. Lidinsky Jr. announced the fourth annual update to the FMC study of U.S. Inland Containerized Cargo Moving through Canadian and Mexican Seaports.

On a positive note, the Northwest Seaport Alliance containerized imports increased 23.1 percent year-over-year (2014 to 2015), Lidlinsky said in a statement to accompany the report released a week ago.

Overall, Canadian shipping terminals, primarily in Vancouver and Prince Rupert, British Columbia, saw an inbound trade growth of 6.8 percent last year (7.0 percent in 2014) compared to 3.8 percent increase to U.S. ports in 2015 and 6.1 percent the year before.

The FMC analysis pointed to new vessel alliances and reaction in terminals that resulted in congestion at West Coast ports, continued growth in non-U.S. terminals and lasting effects from the 2015 shutdown of Pacific terminals in the U.S. by a labor dispute between longshore workers and shipping operators.
