If you want to do some interesting searching check out the container shortage and clogging. There is a problem on where the empty containers can be stored, when the truck drivers will pick up loaded ones, shortage of drivers, inability to off load ships, heavy overtime expenses, 20 to 50 percent increases in shipping expenses, ships standing off shore for weeks at a time eating up payroll and lack of shipping movement. Plus investigate the losses of containers overboard per year. It is a mess.
