Vessel Queues Return to Levels Not Seen Since the Pandemic Era
Anyone shipping cargo out of China this year has likely felt it, even if they couldn't name the cause: bookings taking longer to confirm, vessels running behind published schedules, and a general sense that the gateway ports are under more strain than usual. That impression is backed up by what's actually been happening on the water. Through 2026, vessel queues have built up at times at major Chinese gateways, including Shanghai, the world's busiest container port. At points during the year, reports have put the number of vessels queued outside these ports above 100 — among the largest backlogs the industry has recorded since the peak of pandemic-era port congestion several years ago. For a freight forwarder managing bookings and schedules on behalf of clients, that kind of queue length translates directly into delayed departures, missed connections, and knock-on disruption further down the supply chain.
It's worth being clear about what this congestion is and isn't. It hasn't been a constant, unbroken backlog throughout the year — queue lengths have moved up and down at different points in 2026 — but the peaks have been severe enough, and frequent enough, to make port congestion one of the defining operational stories of the year for China-origin shipping. Shippers who assumed the worst of pandemic-era congestion was a one-time event, unlikely to recur at similar scale, have had to revise that assumption at least somewhat this year.
What's Actually Driving the Backlog
Port congestion rarely has a single cause, and 2026's version is no exception — it's the product of several pressures arriving at once. A significant contributor has been tariff-linked cargo rushes: shippers front-loading orders ahead of new duties, trying to get goods out of China and onto the water before a tariff change takes effect, which creates sudden surges in export volume that gateway ports and their associated trucking, rail, and customs infrastructure aren't necessarily staffed or equipped to absorb smoothly. Layered on top of that has been uneven demand more generally through the year, with booking volumes swinging up and down in ways that make capacity planning harder for terminals and carriers alike.
A third factor, less obvious but arguably just as significant, has been the knock-on effect of Red Sea and Cape of Good Hope rerouting. With major carriers continuing to route Asia-Europe and related strings around the Cape of Good Hope rather than through Suez, voyages take longer, which means more vessels are needed to maintain the same sailing frequency. That absorbs vessel capacity that might otherwise have been available to relieve pressure elsewhere in the network, including at congested load ports in China — one more way in which the Red Sea situation and Chinese port congestion are connected rather than separate stories.
Congestion Spreading Beyond the Main Gateways
One of the more notable features of this year's congestion has been its tendency to spread beyond the primary load ports themselves. As backlogs built at Shanghai and other major Chinese gateways, the disruption has periodically pushed out to transshipment and secondary hubs as well — including, at points, some Mexican ports that handle transshipment volumes connected to broader Pacific trade flows. That kind of spillover is a useful reminder that port congestion in one part of the network rarely stays contained; a delay at the origin port ripples through transshipment hubs, feeder connections, and ultimately the destination gateway, extending the effective delay well beyond the number of days a vessel spent waiting for a berth in China.
Equipment Shortages Resurface
Congestion of this scale has also brought back a problem many in the industry hoped was behind them: container and equipment shortages. When vessels queue for extended periods and turnaround times slow, containers spend longer in the system rather than cycling back to pick up new export loads, tightening equipment availability in exactly the markets that need it most. This has affected several lanes in 2026, including, at points, bookings bound for India — a reminder that equipment shortages tend to show up hardest on lanes where import and export container flows are already somewhat imbalanced, since there's less slack in the system to absorb a slowdown.
How This Compares to Pandemic-Era Congestion
It's worth putting this year's numbers in context for anyone who remembers, or has heard about, the extraordinary congestion that gripped global shipping during the pandemic years. At the height of that earlier crisis, dozens of vessels sat at anchor outside major ports for weeks at a time, container availability collapsed, and freight rates reached levels that are still referenced as the historical ceiling for the industry. Reports of vessel queues exceeding 100 ships at Chinese gateways in 2026 don't necessarily mean a full repeat of that scenario — the underlying causes are different this time, tied more to tariff-driven demand surges and rerouting-related capacity absorption than to the kind of global supply chain shutdown seen during the pandemic. But the scale of the queues is genuinely comparable to some of the worst points of that earlier period, which is precisely why industry commentary has been drawing the comparison. For shippers, the practical lesson is the same regardless of the underlying cause: a queue of that size at a major load port translates into real, measurable delay, and treating it as a minor inconvenience rather than a planning input is a mistake.
What a Freight Forwarder Can Actually Do During a Congestion Spike
It's a fair question to ask what a logistics provider can realistically do about congestion it doesn't control. The honest answer is that no forwarder can make a queue of vessels disappear — but there is meaningful work to be done around the edges of the problem. That includes maintaining relationships across multiple carriers so that if one line's vessels are caught in a particularly bad queue, cargo can potentially be moved to a less-affected service instead of waiting it out. It includes tracking congestion data and vessel position information closely enough to give clients realistic, updated transit estimates rather than relying on a carrier's original published schedule once that schedule has clearly slipped. And it includes flagging risk early enough in the booking process that clients with flexibility — on shipment timing, on origin port, or on consolidation versus a dedicated container — can make an informed choice rather than discovering the delay only once cargo is already committed to a specific sailing.
This is also where a forwarder's presence on the ground in China matters. Being able to check directly with terminal operators, trucking providers, and carrier agents in Shanghai, Guangzhou, and other Chinese gateways gives a logistics partner visibility that's hard to replicate from a purely desk-based booking service overseas, particularly during a congestion spike when official schedules and on-the-ground reality can diverge quickly.
Rate Volatility Tracking the Congestion Peaks
Unsurprisingly, freight rates on some transpacific lanes have spiked in tandem with the sharpest congestion peaks this year — a pattern consistent with the ocean freight rate movements covered elsewhere in our August 2026 market coverage. When vessel queues lengthen and effective capacity on a lane tightens, spot rates tend to respond quickly, sometimes before the congestion itself is fully visible in port statistics. Shippers who track both congestion reports and rate movement together tend to get an earlier read on where a lane is headed than those watching either signal in isolation.
What This Means for Your Shipments
- Book earlier than you think you need to. With queues periodically running into the hundreds of vessels at major Chinese gateways, the safety margin that used to exist in typical booking lead times has shrunk considerably.
- Build real schedule buffer into delivery commitments. Treat published sailing schedules as a starting point rather than a guarantee during periods of active congestion.
- Consider consolidation or LCL flexibility during congestion spikes. Smaller, more flexible bookings can sometimes move through a congested network more easily than a large single shipment waiting for one specific sailing.
- Watch equipment availability on your specific lane. If you're shipping to a market that has seen container shortages this year, flag it early with your freight forwarder so alternative equipment sourcing can be arranged if needed.
- Track congestion and rates together. The two tend to move together this year — rising rates on a lane can be an early signal of building congestion, and vice versa.
We've covered the broader dynamics of peak-season shipping delays and how to plan around them in more detail in our guide to peak season shipping delays from China, and for shippers looking for more flexible booking options during periods of tight capacity, our piece on freight consolidation and LCL container sharing walks through how that option works in practice. RR Brothers and Logistics monitors congestion and capacity conditions across our network of Chinese gateway ports daily, so our clients get an early warning rather than finding out about a delay after their cargo is already stuck in a queue.
