Port Congestion and Demurrage: Supplier Work Plan
LA-Long Beach congestion may push a walkout to Wednesday. See the demurrage and detention risk for chandlers, agents and yards, and what to do now.
Port congestion at Los Angeles and Long Beach may delay a threatened Sunday walkout until Wednesday, with 35,688 containers already waiting for rail service. For maritime service providers, the immediate risk is not the picket line itself but the demurrage and detention disputes that follow.
According to The Loadstar (30 October 2026), a small union local representing 250 watchmen could disrupt half of America's busiest port complex. The same report notes the backlog of containers awaiting rail.
What happened and when
The threatened walkout at Los Angeles and Long Beach was originally set for Sunday but may be delayed until Wednesday, according to The Loadstar (30 October 2026). The report highlights that the real danger is the reach of a small union local, not the size of the picket line.
Separately, CargoWise users handling British and Japanese customs declarations suffered messaging delays on Wednesday, though the backlog cleared the following morning, The Loadstar reported (30 October 2026). These delays add friction to an already strained supply chain.
Why congestion creates demurrage disputes
Demurrage (charges for keeping a container at the terminal beyond free time) and detention (charges for keeping equipment outside the terminal) often spike after congestion events. Sara Dandan, founder of FourOneOne, warned that congestion today could mean a fresh wave of disputed detention and demurrage (D&D) charges tomorrow, according to The Loadstar (30 October 2026).
The same article describes a platform designed to challenge what it calls death by a thousand D&D invoices. For service providers, disputed invoices mean delayed payments and more administrative work.
What it means for maritime service providers
Ship chandlers, bunker suppliers, port agents and repair yards feel congestion through changed vessel schedules and tighter cash flow. When a vessel is held at anchorage or delayed at berth, the ETA (Estimated Time of Arrival) shifts, and pre-ordered supplies may need re-scheduling.
- Chandlers: Deliveries timed to a vessel's original ETA may miss the window; re-confirm orders and keep proof of delivery.
- Bunker suppliers: A delayed vessel may need a re-quote; check credit terms before agreeing to new dates.
- Port agents: More time spent on husbandry tasks and coordinating with terminals; track demurrage risk for clients.
- Repair yards: Vessel schedules slip, so dry-docking slots may need reshuffling.
How to respond now
Start by checking which vessels you have quoted or served in the past two weeks at LA-Long Beach. Then contact the technical superintendent or procurement manager to confirm whether the ETA has changed. Use a simple table to track exposure.

Market context: other pressures on shipping
Congestion is not the only issue. The US Navy recorded 27 serious aviation and ship-related mishaps in Fiscal Year 2026, its highest combined total in at least a decade, according to Marine Insight (30 October 2026). Such incidents can divert naval assets and affect port operations.
In the offshore sector, CNOOC brought nine new projects online in 2026, with five hydrocarbon discoveries and 23 appraisal successes, Offshore Energy reported (30 October 2026). This activity supports demand for marine services in the Gulf and beyond.
Meanwhile, Natalia Margioli has taken the helm at the Institute of Chartered Shipbrokers, The Maritime Executive reported (31 October 2026). Leadership changes at professional bodies can signal shifts in industry priorities.
Digital transformation continues to shape customs processes. A 2024 study in Emerging Science Journal examined the EU's eCommerce VAT legislation and proposed a customs clearance application, noting that cross-border e-commerce poses challenges for traditional customs procedures (Emerging Science Journal, 2024).

Frequently asked questions
What is demurrage in shipping?
Demurrage is a charge for keeping a container at the terminal beyond its free time. Port congestion delays pickup and return, so containers sit longer and charges accumulate. Disputes often follow when the invoices arrive weeks later, The Loadstar reported in October 2026. Source: The Loadstar
What is the difference between demurrage and detention?
Demurrage applies to a container kept at the terminal beyond free time; detention applies to equipment kept outside the terminal beyond free time. Both can spike after a congestion event, and both can be disputed once invoices reach the customer. Source: The Loadstar
What is causing port congestion at Los Angeles and Long Beach today?
According to The Loadstar (30 October 2026), 35,688 containers were already waiting for rail service at Los Angeles and Long Beach, and a threatened walkout by a union local of 250 watchmen could disrupt the port complex. The walkout was set for Sunday but may be delayed until Wednesday. Source: The Loadstar
How can ship chandlers protect themselves when vessel ETAs change?
Re-confirm the ETA with the vessel's agent or technical superintendent before dispatch, and keep written proof of the original order and any changes. If a delivery window moves, update the invoice terms and note the reason, so a later demurrage or detention dispute has a documented record. Source: The Loadstar
What should port agents do during a congestion event?
Monitor vessel arrivals and berth availability, tell clients about likely delays and demurrage risk, and keep records of all communications. Those records may be needed if detention and demurrage charges are disputed later, which The Loadstar reports often follows congestion. Source: The Loadstar

Port congestion meaning in practice: ships wait at anchorage or berth and container backlogs build, as at Los Angeles and Long Beach where 35,688 containers were waiting for rail. Demurrage meaning in shipping is a charge for keeping a container at the terminal beyond free time; detention is a charge for keeping equipment outside the terminal, which is why demurrage vs detention matters when you dispute an invoice. Demurrage charges and demurrage fees often spike after congestion events, as Sara Dandan of FourOneOne warned. Re-confirm ETAs, review credit terms and document every schedule change so disputed invoices do not slow your cash flow.
Which vessels should a supplier check first when congestion hits? Start with every vessel you quoted or served at the affected port in the past two weeks, then confirm with the technical superintendent or procurement manager whether the ETA has moved. What does port congestion today mean for a bunker supplier? A delayed vessel may need a re-quote, so check credit terms before agreeing to new dates. How do you keep a demurrage dispute winnable?
