IN Brief:
- SeasC4U reports reduced barge loading around Duisburg and suspension of some upper-Rhine services.
- Restricted draughts are diverting shipments towards road and rail, where replacement capacity is limited.
- Maersk’s 6 October tariff defines gauge-triggered surcharges but does not prove 15 October water readings.
Low Rhine water levels are reducing container barge payloads and interrupting some upstream services, according to freight operators reporting on 15 October 2026. Gunther Ginckels of river logistics specialist SeasC4U said barges around Duisburg-Ruhrort were carrying roughly two-thirds of their normal loads, with heavier constraints further upstream. That proportion is his assessment of vessels in the affected area, not an independently recorded average for every Rhine vessel, terminal or service.
The upper sections around the Kaub gauge have experienced navigation restrictions severe enough for certain barge services to be suspended, diverting some consignments towards rail and road. A loaded barge sits deeper in the water as cargo weight increases; the available draught is limited by the shallowest point along its intended passage and the clearance required below the hull. Reducing the load may permit safe passage, but makes a movement less productive. The precise constraint varies by river reach, vessel, navigation conditions and stowage.
Payload reductions affect fleet utilisation before all navigation stops. The same number of containers may require additional journeys or vessels if fewer can be loaded on each trip, assuming those resources can be found. Operators must also account for weight distribution, delivery sequence and the practical positions of full and empty containers. The two-thirds estimate around Duisburg cannot be translated into a uniform one-third reduction in the total Rhine freight network, nor into a fixed increase in truck demand without details of the affected cargo flows.
Maersk provides a separate measure of the commercial constraints in its 6 October Rhine low-water advisory. Its surcharge tables use water-gauge bands at Duisburg-Ruhrort and Kaub, with different rates for 20-foot, 40-foot and 45-foot loaded containers. The carrier says it cannot guarantee loading below 81 centimetres at Kaub or 181 centimetres at Duisburg-Ruhrort. Those are the thresholds stated in the tariff, not verified gauge readings for 15 October.
At Kaub, Maersk’s published tariff lists a €60 surcharge for a loaded 40-foot container below the 1.51-metre gauge band, increasing to €435 below 0.81 metres and more at lower readings. The charge depends on the actual gauge band and the conditions of the movement; it is not an average Rhine-wide price increase. The table also should not be mistaken for a physical navigation rule binding every operator, since ship draught, route and carrier loading decisions vary.
Transferring cargo to another mode is not an immediate one-for-one substitution. A train movement requires available paths, suitable wagons, terminal lifting capacity and drivers, while road haulage depends on tractor units, container chassis, collection appointments and a viable delivery slot. Ginckels reported that rail services were already fully booked in some corridors and that replacement truck capacity was also constrained. His account describes acute difficulty arranging alternatives, rather than a quantified shortage verified across the whole European rail network.
Ports and inland terminals can encounter knock-on effects when barge rotations become irregular. Imports remain in a terminal stack longer if scheduled barge collections cannot take the expected number of boxes, while export containers may miss a deep-sea vessel cut-off after a delayed inland journey. Rotterdam’s port authority told The Loadstar that its port remained fully operational and that inland waterway volumes were reasonably stable compared with last year. That qualification sits alongside reports of congestion and delays further along the river; the two observations describe different parts of the transport chain.
IN Supply covered a previous shift towards rail during August. The latest October development concerns renewed load restrictions, some suspended upper-river services and their effects during a busier working period. Earlier notices demonstrate that the problem has recurred through 2026, but do not establish the water level on a particular October date. Rainfall, upstream flow, local navigational rules and the recovery of delayed rotations can each affect the time needed to normalise movements.
Cost exposure differs across freight contracts. Shippers buying a carrier-controlled inland move may see a published low-water surcharge, whereas importers procuring separate haulage can face changed quotations and availability for road or rail. The effect on a manufacturer depends on the urgency of the components, available buffer stock and the ability to redirect a consignment in time. A carrier’s table makes one part of the pricing exposure transparent, but it cannot establish a single rate for every shipment connecting Rotterdam or Antwerp with inland customers.
SeasC4U’s report of reduced barge intake and upstream suspensions is the immediate operational evidence, while Maersk’s tariff sets out one carrier’s gauge-based pricing and loading guarantees. Neither source provides a reliable date for the return of ordinary draught or a river-wide recovery forecast. Updated gauge readings, restored barge services and the clearance of delayed container movements will determine when normal rotations can resume.
