Charleston Is Closing a Terminal It Just Reopened. The Volume Numbers Behind That Decision Tell a Wider Story.

Most port capacity announcements are about expansion. This one is about contraction, and the candour with which the South Carolina Ports Authority has explained it makes it worth reading carefully.

The South Carolina Ports Authority announced it will temporarily pause container operations at its Leatherman Terminal starting August 1, consolidating activity at its North Charleston and Wando terminals in the short term. The port attributed the decision to numerous headwinds, an uncertain trade forecast, and tempered volumes. MSC is currently the only shipping line calling at Leatherman, operating around five weekly services, most of which will relocate to North Charleston with the remainder moving to Wando Welch.

The Leatherman Terminal has had an unusually turbulent short life. It opened in 2021, closed in 2023 during a labour dispute between the port and the International Longshoremen's Association, reopened in 2024 after the parties reached agreement, and is now pausing again just two years after that reopening. A terminal that has spent more time offline than online since its launch is a visible symptom of a port system trying to right-size infrastructure to demand that has not materialised as originally projected.

What the port is actually saying

The port's own language is revealing. Shipping lines have been dealing with higher costs and fuel rates, and the port needs to accommodate that and offer more competitive service. The Leatherman Terminal currently handles about 5% of port volumes. That low utilisation rate, combined with the fixed costs of running a dedicated terminal for a single carrier, produced an operating economics calculation that did not justify keeping it open.

The spokesperson put it directly: the port has ample capacity at its other two terminals because of the down market right now. That phrase, down market, is the one procurement teams should hold on to. It describes a port system operating significantly below the capacity that was built to handle a post-pandemic freight boom that has since normalised, on top of trade volumes that have softened further due to tariff-driven demand uncertainty.

The closure timeline is also open-ended in a way that is unusually honest for a port authority. The spokesperson said the reopening depends on numerous factors including the strength of returning volumes, the overall port industry, capacity needs, and the ability for SC Ports to make costs more competitive. There is no committed reopening date. There is no minimum volume threshold that would trigger one. It reopens when the market justifies it.

The wider demand picture behind one terminal's closure

The Leatherman pause is one data point in a freight market that has been absorbing conflicting signals throughout 2026. On one hand, volumes diverted from the Strait of Hormuz have added demand to Atlantic and Pacific US ports as shippers reroute around the closed waterway. On the other, tariff uncertainty has dampened import planning, with many US importers pulling forward orders earlier in the year and then pausing to assess the trade policy landscape before committing to further volumes.

Ocean shipping recovery is still a ways off despite the US-Iran ceasefire pact that was recently announced. Port systems that invested in capacity during the 2021 to 2022 freight surge are now managing infrastructure built for a volume ceiling that the current market is not approaching. Charleston's decision to consolidate is rational. It is also a signal that the East Coast port market, which had been absorbing Atlantic diverted cargo from Hormuz disruption, is not running at the utilisation levels those diversion flows might have implied.

The exposure for European and Asian companies

For any shipper routing containerised cargo through Charleston, the Leatherman pause changes nothing immediately. MSC services are relocating rather than disappearing, and the port has confirmed it will handle those volumes through its other two terminals. The operational impact on individual freight movements is expected to be minimal during the transition.

The supply chain signal the closure sends is separate from the operational impact. A port authority pausing a terminal that handles only 5% of its volume, publicly citing a down market and uncertain trade forecasts, is flagging that the East Coast freight recovery is not yet running at a pace that justifies the port infrastructure built around more optimistic projections.

The disruption does not arrive as a missed shipment or a congestion event. It arrives as a terminal that was built, closed, reopened, and is now pausing again, with no confirmed date for what comes next.
