Ocean carriers are revising schedules and imposing surcharges due to a potential strike at East and Gulf Coast ports, which could disrupt operations if a contract renewal isn’t reached by a deadline. This strike could severely affect industries like retail and manufacturing, leading to shortages and increased logistics costs. Carriers like Maersk, CMA CGM, Hapag-Lloyd, ONE, and MSC are implementing various surcharges ranging from $800 to $3,798 for different container sizes to manage increased operational costs amid the anticipated disruptions. Shippers are urged to finalize contingency plans promptly.
