A 24-hour general strike on November 11 halted normal container loading and unloading at Spain's leading ports of Algeciras, Valencia and Barcelona, while road blockades sharply disrupted freight traffic at Tarragona. Algeciras' two principal container terminals suspended commercial operations from 2 a.m., Valencia's port authority confirmed that vessel cargo handling had stopped, and Barcelona's port authority suspended stevedore-dependent operations and associated customs inspections. At Tarragona, official port records show truck arrivals fell 97.47%, from 1,586 to 40, between midnight and 2 p.m. compared with the same period in 2025. Unions UGT and CCOO estimated 90% participation across the port sector, although employers reported substantially less disruption across the wider Spanish logistics industry.
Spain's Major Container Gateways Hit by a 24-Hour Strike
Vessel-handling stoppages at Algeciras, Valencia and Barcelona coincided with severe road and rail interruptions at Tarragona.
Port-by-Port Operational Findings
Confirmed or reported disruptions on Wednesday, November 11. These descriptions do not imply that every activity at each port ceased.
Facilities: APM Terminals Algeciras and Total Terminal International Algeciras.
Schedule: Commercial operations stopped at 02:00 November 11, with resumption scheduled for 02:00 November 12.
Exception: Essential ferry and supply connections with Ceuta were maintained.
Port authority: Vessel loading and discharge halted during the strike.
Exception: Refrigerated containers and dangerous cargo continued receiving essential attention.
Recovery: Container terminals planned to open landside operations from 06:00 on November 12.
Official notice: Work requiring dockworkers was suspended, including associated customs inspections at terminals.
Terminals: APM Terminals Barcelona and Hutchison Ports BEST announced 24-hour operating suspensions.
Exception: Pilotage, tug assistance, passenger services and bunkering minimums were retained.
Roads: A-27, Moll de Reus and Llevant access points blocked during the morning.
Truck movements: Only 40 arrivals and nine departures from 00:00 to 14:00.
Recovery: Access began reopening around midday. Morning rail departures required rescheduling.

Three Affected Ports Handle Three-Quarters of Spain's Container Traffic

Which Operational Interfaces Were Affected?
The differences matter because a stopped crane, inaccessible truck gate and suspended customs examination create different recovery problems.
| Port | Reported Operational Interruption | Remaining / Essential Services | Recovery Issue to Verify |
|---|---|---|---|
| Algeciras | APM and TTI commercial container operations suspended during the 02:00-to-02:00 strike window. | Essential maritime services and specified supply connections to Ceuta remained available. | Actual resumption, vessel waiting lists, transshipment connections and any separate weather-related impacts. |
| Valencia | Normal vessel cargo loading and unloading stopped; commercial terminal work heavily affected. | Essential refrigerated and dangerous-cargo support, depot operations and other unaffected services. | 06:00 landside restart, November 12–13 truck arrivals, yard congestion and berth schedule recovery. |
| Barcelona | Stevedore-dependent cargo activity halted; terminal customs inspections requiring stevedores unavailable. | Required pilotage, towage, mooring, passenger services, bunkering, LNG supply and permitted special-cargo procedures. | Gate and vessel operation restart, customs inspection queue, reefer handling and delayed vessel departures. |
| Tarragona | Port access restrictions reduced truck movements sharply. Morning rail departures were canceled. | Port authority said minimum pilotage, towage, mooring and MARPOL services were maintained. | Truck and rail recovery after reopening, including effects of earlier metal-sector protests. |
| Other Spanish Logistics | Localized protest and transport disruptions reported elsewhere; the walkout's impact was uneven. | UNO said much of the wider freight and logistics industry continued operating. | Avoid extending port terminal conditions to the entire Spanish economy without evidence. |
Three Different Risks After the Strike
Stopped vessel handling may require additional crane windows, revised feeder connections or changed vessel departure plans.
Trucks deferred during the strike may arrive together, increasing demand at gates and container yards during recovery.
Inspection work suspended at Barcelona may need to be rescheduled independently of the reopening of vessel operations.
How Long Will It Take to Clear a Port Strike Backlog?
Model deferred container handling, additional recovery capacity, backlog clearance and potential operational costs following a port stoppage.
Port & Recovery Assumptions
Baseline TEU references come from 2025 annual port statistics divided by 365. Replace them with actual daily handling plans whenever available.
Advanced Operational Inputs
Illustrative throughput not completed during the specified interruption. This is not a verified number of containers delayed in Spain.
Modeled Recovery Backlog
Each point represents end-of-day unfinished extra handling work. The model assumes routine new daily cargo is processed separately from the added recovery capacity.
Illustrative Cost Exposure
Costs below refer to different stakeholders and may overlap in actual contracts. They are shown separately rather than aggregated into a claimed economic loss.
Daily Recovery Register
| Day | Workday? | Backlog at Start | Extra Work Cleared | Backlog at Close | Cumulative TEU-Days |
|---|
Starting references: Valencia 5,662,661 TEU; Bay of Algeciras 4,739,853 TEU; Barcelona 3,726,625 TEU; combined 14,129,139 TEU in 2025, including transshipment and empty containers. Daily reference values divide each annual total by 365 and are rounded for display. These historical averages are not the actual November 11 vessel plans, cargo moves, lost terminal productivity or customs release volumes.
Deferred handling = selected normal daily TEU × disruption hours ÷ 24 × (1 − capacity retained during interruption). The model adds any user-entered preexisting backlog. Extra daily recovery handling = normal daily TEU × recovery uplift percentage, and only that surplus capacity is used to clear the deferred work. The routine daily flow is assumed to continue unchanged. This deliberately ignores dynamic vessel arrivals, yard capacity, berth conflicts, crane allocation and congestion effects.
Recovery day one is modeled as Thursday, November 12, 2026. Advanced-mode calendars permit 5, 6 or 7 working days per week. On nonworking days the existing backlog remains outstanding. Waiting TEU-days are the sum of the modeled backlog at each recovery day's close. The cost calculation covers the selected review horizon only and excludes any waiting time before the recovery period. The model separately estimates the calendar days required to clear backlog under constant conditions, up to a 365-day limit.
Illustrative cargo waiting expense = TEU-days × selected charge per TEU-day. Additional handling expense = recovery TEU actually cleared in the review window × incremental handling cost per TEU. The vessel-time estimate = selected vessel count × waiting hours ÷ 24 × selected daily time value. These may be borne by different parties, may be reduced by contract terms or grace periods, and may overlap. The tool does not calculate demurrage automatically or determine contractual liability.
