Two Baltimore stevedoring companies, Ports America Chesapeake (PAC) and Marine Terminals Corporation-East (MTCE), have lodged a complaint with the Federal Maritime Commission (FMC) against marine terminal operator (MTO) AMPORTS. The companies allege that AMPORTS tried to exclude them from port work and then invoiced PAC $1.2 million in fees for not being their preferred stevedoring provider. AMPORTS had claimed exclusive rights for stevedoring services, imposing a fee on other companies. PAC and MTCE argue that AMPORTS had no legal basis for the fee. Despite temporarily suspending the fee, AMPORTS later reinstated it and retroactively invoiced PAC. The stevedoring companies seek resolution through an oral hearing before the FMC.
