U.S. vessel imports have declined almost 3 percent from May to June. Imports are also 1.6 percent below TEUs (twenty foot containers) seen in June of 2012. This year, U.S. ocean imports had a steady increase of 1 percent compared to the volume seen in 2012, but with the low June numbers that percentage has changed. Zepol has found that in the first six months of this year, compared to January through June of 2012, import volume is virtually stagnant. In fact, 2013 is down 0.3 percent, if you want to be picky.
