United States-bound waterborne shipments saw some growth in April, albeit not at the same levels it hit in previous months, according to data issued this week by global trade intelligence firm Panjiva. April shipments, at 955,956, saw a 0.3% gain compared to April 2017, getting annual shipment growth back on a positive track, following March’s 0.2% annual decline. March’s annual decline was the first one going back to a 7.7% annual drop-off in February 2017.
