Detention and Demurrage
The Commission’s current focus on issues related to detention and demurrage dates back to 2014 when the Commission hosted multiple forums on maritime congestion. The feedback received from these forums was integrated into the 2015 FMC report, “Rules, Rates, and Practices Relating to Detention, Demurrage, and Free Time for Containerized Imports and Exports Moving Through Selected United States Ports.”
In 2018, Commissioner Rebecca Dye was named the investigative officer for Fact Finding 28, which focused on the impact of detention and demurrage on supply chain efficiency. Commissioner Dye issued multiple recommendations from this fact-finding, including a proposed interpretive rule on detention and demurrage under the Shipping Act. The NPRM for the interpretive rule received over 100 comments from the public and the final rule was issued in May 2020.
The pandemic brought additional challenges to the supply chain and, in response, the Commission initiated Fact Finding 29, again with Commissioner Rebecca Dye as investigative officer. While this fact finding centered on engagement with supply chain stakeholders to identify solutions to the pandemic’s disruption of the supply chain system, maritime congestion resulted in renewed attention on detention and demurrage.
As part of the fact finding, Commissioner Dye issued an information demand on detention and demurrage practices among carriers and the largest marine terminal operators. The Fact Finding 29 recommendations included the proposed issuance of a rulemaking concerning information on detention and demurrage billings. An Advance Notice of Proposed Rulemaking was issued by the Commission in February 2022.
Detention and Demurrage Data
As part of the audit program, data are collected quarterly from the following carriers: CMA CGM, COSCO, Evergreen, Hapag-Lloyd, Hyundai Merchant Marine, Maersk, Mediterranean Shipping Company, ONE, and Yang Ming.
These data are provided for a general understanding of the scope of detention and demurrage billed and paid to carriers. Detention and demurrage accrues from extended use of equipment and congestion at terminals and inland points drives extended use of equipment.
The chart below indexes the aggregate data provided by the carriers. The indexed chart is intended to provide a way to track and compare trends in detention and demurrage billed, collected, and waived using Q2 2020 as the base period, which has a value of 100.
The total amount of detention and demurrage billed increased roughly nine-fold and detention and demurrage collected increased roughly ten-fold between Q2 2020 and Q1 2022. All indices decreased substantially from their peak through Q3 2023. The amount of detention and demurrage collected is 86 percent higher than that in Q2 2020, and both the amount of detention and demurrage billed and the amount waived are roughly 40 percent higher than Q2 2020 levels.
In dollar terms, the nine carriers have collected roughly $13.8 billion in detention and demurrage charges between April 2020 and September 2023.
The FMC continues to collect these data from the carriers on a quarterly basis and will update the chart and numbers on this website accordingly.
