Most people only started worrying about port congestion when COVID turned it into front-page news. For supply chain managers, however, this has long been a risk to monitor, and the situation has not followed a straight line back to normal. Here is some guidance on how to know when it might be time to switch to express air, and how to keep your supply chain moving when sea lanes become congested.
Prolonged delays at a congested port can trigger stockouts, cause you to miss contract deadlines, and raise the risk of product obsolescence before your goods ever reach the market. Relying on traditional bulk freight may leave your operations vulnerable to these sudden logjams, especially if you're shipping out of a high-volume port like Laem Chabang Port.
Our DHL Express network lets you bypass slow maritime routes and keep materials flowing, giving you an alternative to clogged ocean lanes when port wait times increase.
Global port congestion has genuinely improved since the pandemic years, but that story hides real regional variation. According to Kpler's 2025 port congestion analysis, berth waiting times can still stretch to several days during peak periods at major hubs. For example, some key gateways saw vessel delays of 6 to 10 days during mid-2025 peak conditions alone.
Preparing alternative transport channels ahead of time is what can protect your operations from these compounding costs, wherever the next bottleneck might appear.

Marine bottlenecks can ripple through every part of the retail pipeline behind a delayed shipment, showing up as stranded capital, contract penalties, and spoiled goods.
Extended delays at the dock can stall your inventory and trigger mounting daily storage charges from port operators. These fees may accumulate quickly and eat into your product margins, so managing them requires clear planning and a defined exit strategy.
Local regulations set specific detention windows that vary by harbour, and these are overseen by bodies like the Port Authority of Thailand (PAT). Shippers should be aware of customs hold processing timelines from the Thai Customs Department, as these can also be impacted during periods of high congestion, leading to further delays and potential fees.
Weather gets most of the attention, but it's rarely the only factor behind a congested port. Labour disputes, equipment shortages, and capacity constraints at major hubs can back up shipping schedules just as badly, and geopolitical chokepoints add another layer of unpredictability.
Regional weather hazards can still amplify these existing pressures. Extreme storms and seasonal monsoons may force ports to halt loading operations entirely, and even a short closure at an already-stretched hub can take weeks to clear.
In Thailand, the annual monsoon season can disrupt both port operations and the land-based logistics required to move containers to and from hubs like Laem Chabang. Heavy rainfall may lead to operational shutdowns and delays in container processing. Capacity also tightens significantly during the Songkran festival period, which can compound any other factors already slowing a given port down. Planning for these predictable seasonal pressures is a crucial part of risk mitigation.
Air redirection often makes financial sense when the cost of production downtime or contract penalties exceeds the premium price of air freight. Paying a higher shipping rate can be cheaper than letting a factory floor stand idle, and meeting a seasonal retail launch date may be more important for your market share than the extra cost.
Clear calculations inside MyDHL+ give shipping managers transparent pricing to run a rapid cost-benefit assessment. Comparing real-time rates this way supports quick decisions the moment your ocean cargo is delayed.
These are the situations where the premium may pay for itself:
Financial Scenario | Operational Impact | Strategic Benefit |
|---|---|---|
Emergency Parts | Sourcing broken machinery components | Reduces expensive factory stoppages |
High-Value Launches | Moving premium electronics via air | Helps avoid missing seasonal sales windows |
SLA Penalties | Shipping urgent goods via air | Helps you avoid heavy non-compliance fines |
Daily penalties, such as bonded storage fees for shipments held in customs, can start at over THB 240 per day and erase your product margin fast once you run the numbers.
Congestion never really left the picture after COVID put it on the map, and which port gets hit next is only getting harder to predict. Relying on congested seaports exposes your business to expensive delays and stockouts that you could plan around instead of absorbing. DHL Express can support that shift with tools like MyDHL+ for real-time rate comparison and high-priority air express options for the shipments that cannot afford to wait.

Port bottlenecks delay raw materials and finished products, leading to empty shelves and missed sales. These disruptions also trigger expensive storage fees and contract penalties from waiting buyers, which is why alternative options like express shipping are important for protecting cash flow.
Severe storms and seasonal weather like monsoons can shut down port crane operations and loading docks for days. These brief closures can snowball into backlogs that slow shipping lanes for weeks. Shifting to air cargo paths helps you maintain predictable delivery times despite this seasonal disruption.
Air express makes sense when the cost of letting your production lines stand idle is higher than the price of air transit, and it's especially useful for high-value items, seasonal launches, and urgent replacement parts. MyDHL+ lets you compare rates and run that trade-off quickly.
When ports are congested, customs offices face an overwhelming volume of documents, which can slow down standard clearance processing significantly. Our DHL Express team and digital tools help you organise import paperwork and file declarations before arrival, cutting the risk of an expensive hold at the border.
DHL Express provides high-priority air express routing that helps you bypass clogged maritime lanes, with time-definite options like DHL Express 9:00 and DHL Express 12:00 built around a set delivery window. You can manage and track these shipments in real time using MyDHL+.
