First decrease since February, lighter peak-season demand seen Oakland, Calif. - Containerized import volume at the Port of Oakland declined last month for the first time since February.   The Port said today that October import totals were down 3.3 percent compared to 2014. The Port attributed the decrease to lighter-than-usual peak-season activity. Autumn is usually the busy time in container shipping when retailers import goods for holiday store shelves. But ocean carriers are reporting lower demand for space on their ships. The Port said October export volume decreased 13.7 percent. Overall container volume – which includes imports, exports and empty containers – was off 6.9 percent. Before last month, Oakland had reported seven consecutive months of import gains dating back to last winter.
