Are delays at the port disrupting your supply chain?
Port congestion occurs when an excessive number of ships attempt to use a port simultaneously, causing delays in unloading and moving goods. At Manila Port, the average wait time for dry bulk vessels has increased from 6.5 to 10 days as of April 28, 2025, with overall ship wait times ranging from 7 to 10 days due to limited infrastructure and high cargo volumes. This congestion affects businesses that rely on timely deliveries, disrupting inventory cycles and causing imbalances, stockouts, and higher shipping costs.
TL;DR
- Port congestion is driven by surges in shipping volume, outdated infrastructure, and geopolitical issues, resulting in delays and increased costs.
- Business impacts include delayed deliveries, increased shipping fees, inventory disruptions, and strained cash flow.
- Solutions: Diversify ports, utilize real-time tracking, pre-clear customs, and improve inland logistics coordination.
- Effective strategies include flexible warehousing, maintaining backup suppliers, and closely monitoring port conditions.
What Is Port Congestion?
Port congestion occurs when cargo ships experience delays at seaports due to slow unloading, limited infrastructure, or cargo backlogs. This results in longer wait times, higher costs, and supply chain disruptions.
If you rely on imports or time-sensitive deliveries, these delays can impact your ability to restock inventory, fulfill orders, and meet customer expectations. For e-commerce operations, especially in fast-moving markets like the Philippines, even minor port delays can disrupt fulfillment and hurt customer satisfaction.
The factors behind port congestion are multifaceted. To understand the root of the issue, we’ll now look at the causes driving these delays.
What Causes Port Congestion?
In 2025, port congestion is caused by issues such as outdated facilities, uneven shipment volumes, and limited space, particularly at busy ports like Manila and Los Angeles. These issues disrupt cargo movement and create ripple effects that directly impact your delivery timelines, inventory planning, and customer experience.
Below are the core causes and why they matter to your business:
- Surges in Shipping VolumeSurges in container traffic frequently strain port capacity, resulting in delayed cargo movement and processing. In 2024, Manila South Harbor handled 1.29 million TEUs, while Sangi Port experienced congestion, with fluctuations ranging from 1 to 3 vessels per week in early 2025. These volume spikes disrupt scheduling and create delays that affect your deliveries and inventory flow.
- Limited Port Infrastructure
Many ports still rely on outdated systems and lack sufficient berths, cranes, or automation, which limits their capacity to process modern cargo volumes efficiently and contributes to delays. - Geopolitical Disruptions and Rerouting
Conflicts in the Red Sea and South China Sea have led vessels to reroute away from their usual trade lanes, resulting in more traffic being directed toward alternative ports, such as Singapore and Subic Bay. This overcrowding creates backlogs, particularly during periods of high volume. - Blank Sailings and Skipped Port Calls
This occurs when carriers cancel or skip scheduled stops to manage delays or reduce losses, which disrupts port scheduling, causes uneven workloads, and delays cargo flow. Asia–U.S. routes saw blank sailings rise from 9% in March to 24% in May 2025, resulting in uneven workloads that delayed clearing and forwarding. - Labor Constraints and Terminal Delays
A shortage of trained port workers and limited customs processing shifts cause cargo to pile up awaiting clearance. In Southeast Asia, slow adoption of automation and reliance on manual documentation processes exacerbate these delays.
Understanding these causes sets the stage for realizing just how deeply the effects of port congestion impact business operations. Let’s now see how these delays directly affect your shipping and logistics.

How Does Port Congestion Affect Shipping?
For any business relying on imports, exports, or regional distribution, port congestion disrupts the flow of goods at the most critical handover points. Here’s how it directly impacts your shipping and logistics:
- Extended Vessel Wait Times: Ships frequently experience multi-day delays before docking or unloading, particularly at overstretched ports like Manila and Subic. This stalls your inbound inventory and delays every step downstream, from warehousing to last-mile delivery.
- Unpredictable Delivery Timelines: Delays in port clearance and onward transport reduce your ability to promise reliable ETAs. Customers expect speed, and inconsistency erodes trust, especially in highly competitive online marketplaces.
- Rising Shipping and Handling Costs: Carriers introduce congestion surcharges, and port delays result in increased demurrage and detention fees. These hidden costs erode your margins and complicate the management of your logistics budget..
- Limited Access to Containers and Space: Congestion leads to fewer available containers and reduced booking flexibility. This limits your ability to scale shipments or respond quickly to sales spikes and marketing pushes.
In the next section, we’ll examine how these shipping delays affect your business performance and profitability.

Practical Solutions to Reduce Port Congestion Impact
Reducing the effects of port congestion isn’t just about reacting quickly; it’s also about anticipating and mitigating potential issues. It’s about building resilient systems that give you control, even when external conditions shift.
Below are proven strategies to help you protect delivery timelines, reduce costs, and keep your supply chain moving, especially if you’re managing e-commerce or cross-border trade in the Philippines or Southeast Asia.
1. Diversify Port Access
Relying on just one port can cause problems if there’s a delay, so using different ports, such as Subic Bay, Batangas, or Davao, can help keep your shipments moving smoothly even if one port has a backup.
2. Strengthen Inland Logistics Coordination
Even if your goods clear the port on time, problems with trucks or deliveries can still cause delays. You need to know how your products will get from the port to your store or warehouse. Work with delivery partners who can manage the entire journey from the port to your door. This helps ensure you don’t lose time and meet deadlines, even when there are disruptions like adverse weather conditions.
3. Work With Digitally Equipped Logistics Providers
Outdated logistics systems relying on manual tracking and paperwork can cause errors and delays, but solutions like Inspire Solutions Asia offer streamlined warehousing, real-time inventory management, and automated order fulfillment tailored for e-commerce businesses in the Philippines.
4. Pre-Clear Customs Through Digital Submissions
Waiting for customs to clear your goods can result in a significant delay. If you send your documents ahead of time, you can expedite the customs clearance process for your goods. Online platforms can simplify the process of submitting papers and reduce the likelihood of errors. By taking care of customs before the shipment arrives, you’ll speed up the process and avoid delays or fines.
5. Track Vessel Movement and Port Conditions
To prevent delays, monitor ships and port conditions carefully. Watch for factors like ship arrival times and whether the port is overcrowded. Digital tracking platforms provide forecasts on vessel arrivals and weather conditions, enabling proactive route adjustments and minimizing delays.
6. Use Local Fulfillment and Flexible Warehousing
If you store your products closer to your customers, you’ll be less affected by international shipping delays. Local warehouses help you ship faster, even if your goods are still at the port. You can also utilize flexible fulfillment centers that adjust to sudden changes in demand, which is particularly helpful in places like the Philippines, where delivery speed is a key consideration for customers.
7. Maintain Backup Suppliers and Inventory Buffers
If you rely on just one supplier or route, you might face serious problems when delays happen. Ensure you have alternative suppliers to work with and maintain an extra stock of essential items. This way, even if there’s a delay, you can keep your business running without problems.
With these practical solutions, it’s possible to reduce the impact of port congestion on your business. But how do these disruptions truly affect your operations? Let’s take a closer look at how port delays impact your bottom line.

Impact of Port Congestion on Your Business
Port congestion delays shipments and triggers a chain reaction impacting operations, costs, and customer experience in the following ways:
- Delayed Deliveries Break Customer TrustWhen your shipments are delayed at the port, your orders can’t be shipped on time. Customers waiting for next-day or even standard delivery lose patience, and you risk negative reviews, refund requests, and churn. For high-growth e-commerce businesses, even a one-day delay can lower your marketplace ranking and kill repeat purchase intent.
- Higher shipping costsCarriers impose congestion surcharges, demurrage fees, and rerouting costs during port delays, which increase your expenses; meanwhile, customers continue to expect competitive prices and free shipping, thereby pressuring your profit margins.As spot rates from Shanghai to Los Angeles soared to USD 3,136 per 40-foot container in May 2025, up 16% in one week, as port stress and tariff reprieves surged demand
- Inventory Pile-Ups and Stockouts Disrupt OperationsWhen goods arrive late, your warehouse experiences an uneven flow, either too much stock at once or nothing for days. This unpredictability leads to either overselling or excess holding costs. You lose control over fulfillment schedules and waste valuable storage space.
- Fulfillment Becomes ReactiveCongestion forces your logistics into crisis mode, consuming time tracking delays and rescheduling, which detracts from efforts to improve efficiency, grow, or plan campaigns.
- Cash Flow Gets StrangledInventory stuck at sea isn’t selling. But you’ve already paid for it, or borrowed to finance it. The longer those goods sit idle, the tighter your working capital becomes. You might delay other purchases or stall your growth pipeline to cover the gap.
The ripple effect of port congestion extends far beyond logistics. It encompasses customer experience, cost control, and financial stability. So, how can your business manage these challenges?
