U.S. import volumes have rebounded at west coast ports so far this year, according to figures released from Datamyne, a provider of international market intelligence.

Imports through the port of Los Angeles increased 36 percent January through February of 2016 and 30 percent through the port of Long Beach, compared with the same time period in 2015.

The port of Oakland also had a notable 52-percent increase in import TEUs compared with January and February of 2015.

“West coast ports have indeed made a comeback from the labor disputes and slowdowns that negatively impacted volumes in early 2015” said Brendan McCahill, CEO of Datamyne. “Combined, Los Angeles and Long Beach made up for 39 percent of all ocean imports to the United States in January and February of this year, up four percent over the same two months last year.”

East and Gulf Coast ports did not see the same sweeping growth. Compared to January through February of last year, the port of New York/Newark increased in import volume by five percent, Norfolk, was up 17 percent, and Houston declined four percent.

The port of Savannah, which looked to have prospered from the western slowdowns last year, has continued to grow by nine percent so far this year.
