Zepol Corporation, the leading trade intelligence company,reports that U.S. import shipment volume for August, measured in TEUs, is down from July by 3 percent and 0.3 percent from August 2011. It's unusual to see a drop in imports from July to August, since the trend for the past three years has been a spike in the month of August. In 2010 and 2011, August was actually the peak month of the year for TEU imports.
