North American freight shipments rose modestly in September, a month usually associated with a peak season increase. This month's 2.2-percent increase can be attributed, however, more to contingency planning for the anticipated International Longshoreman's Association (ILA) dock workers strike than to a seasonal surge in orders. Although federal mediators stepped in at the last minute and negotiated a three-month extension to continue talks, many shippers had already scrambled to re-schedule October shipments for September. The alternative, should the strike have occurred, was to reroute goods to the West Coast, where carriers were charging strike surcharges ranging from $300 to $1,000.
