In keeping with US President Joe Biden's executive order, the Federal Maritime Commission (FMC) has established a programme to look at detention and demurrage fees levied by leading liners.

The commission announced the Ocean Carriers Audit Program on Tuesday, tasked with ensuring the nine top boxship companies by market share are charging reasonable fees related to the return and receipt of containers.

"The Federal Maritime Commission is committed to making certain the law is followed and that shippers do not suffer from unfair disadvantages," commission chairman Daniel Maffei said.
