Port congestion is a common challenge in international shipping. Causes include peak season cargo surges, terminal equipment failures, labor shortages, regulatory policies (such as increased customs inspections), and extreme weather. These can lead to ship and container delays, and increased transportation costs. Addressing congestion requires a three-pronged approach: proactive avoidance, efficient adaptation, and risk transfer.
In this article, Weefreight provides a detailed analysis, which we hope will be helpful.
- Advance Planning: Avoiding Congestion Risks at the Source
- Selecting Alternative Ports or Routes
If the target port (such as hub ports like Los Angeles or Singapore) is chronically congested, consider selecting a nearby alternative port and then using inland transportation (such as trucking or rail) to reach the final destination. For example, cargo originally destined for the Port of Los Angeles could be rerouted via the Port of Long Beach (only 30 kilometers away) or the Port of Oakland. While this would incur additional short-haul transshipment fees, it would significantly reduce vessel demurrage. Alternatively, if the Port of Rotterdam is congested on a European route, the Ports of Hamburg and Antwerp could be used as alternatives.
Also, you can negotiate with your carrier to adjust the route type: avoid direct routes (if the direct port is congested) and opt for transit routes (using a less congested transit port for distribution), or choose dedicated routes to smaller ports (some smaller ports have lower cargo volumes and a lower probability of congestion, but it’s important to verify the availability of inland transshipment networks).
- Stagger Shipping Times
Port congestion often exhibits seasonal patterns, such as before the European and American Christmas season (August-October each year), after the Chinese New Year (February-March), and around major e-commerce promotions (such as Black Friday and Singles’ Day). These concentrated surges in cargo volume can easily lead to congestion. Peak load times can be avoided through the following methods:
If the shipment is not urgent, ship 1-2 months earlier or later to avoid peak season;
Consult customers for “split shipments,” breaking large orders into multiple smaller shipments to avoid congesting port resources and reducing the risk of “whole-shipment delays”;
Pay attention to real-time port congestion alerts (e.g., shipping company websites, port authority announcements, and logistics platform data). If a port has issued a “congestion alert” (e.g., vessel waiting times exceeding 72 hours), adjust shipping plans promptly.
II. Optimizing Operations: Improving Port Connection Efficiency
- Complete Documentation and Compliance Procedures in Advance
When ports are congested, customs inspections and document review processes become more stringent. Errors in documents (e.g., inconsistent bill of lading information, incomplete customs declarations) can easily lead to cargo being detained, further exacerbating delays. Required:
Confirm the accuracy of all documents (bills of lading, commercial invoices, packing lists, certificates of origin, customs declarations, etc.) 1-2 days before shipment, especially ensuring consistency between documents and goods (e.g., the name, quantity, and weight of the goods must exactly match the customs declaration information).
If the goods are subject to special regulations (e.g., dangerous goods, food, or pharmaceuticals), prepare the corresponding compliance documents in advance (e.g., the IMDG code for dangerous goods, health and quarantine certificates for food) to avoid inspection delays due to missing documents.
Select the “Pre-declaration” service: Some ports support “advance declaration” (such as China’s “Advance Declaration, Inspection and Release Upon Arrival” model). This allows you to complete the customs declaration process before the goods arrive, allowing for direct release upon arrival, shortening the time spent at the port.
- Optimize the connection between container pickup and return and warehousing
Port congestion is often accompanied by “difficulty in container pickup” (overstocked containers, insufficient terminal cranes) or “slow container return” (poor empty container return flow). Advance coordination is necessary to improve connection efficiency:
Before container pickup: Confirm the container’s location with the container yard or carrier (whether it is at the “near-port yard” or “far-port yard”) and schedule a pickup time in advance (to avoid on-site queues). If there are no containers at the near-port yard, “far-port pickup” is acceptable (although this incurs an additional freight charge, it avoids waiting).
Before container return: If empty containers need to be returned after cargo is unloaded, confirm the “empty container acceptance plan” with the container yard in advance to avoid empty containers being unable to be returned due to a full yard, which would tie up truck resources.
Temporary storage buffer: If port pickup is expected to be delayed, contact a nearby temporary storage warehouse in advance to unload the cargo and temporarily store it, then collect and transport the containers in batches. This avoids the deadlock of “cargo waiting for containers” or “containers waiting for cargo” after the ship arrives at the port.
- Strengthen real-time communication with all parties.
Port operations involve multiple parties, including shipping companies, terminals, customs brokers, and towing companies. Information gaps can easily lead to process bottlenecks. A multi-faceted communication mechanism should be established:
Maintain daily communication with shipping companies to confirm vessel status (e.g., whether the estimated arrival time is delayed or whether berthing needs to be adjusted). If a ship is stranded, promptly obtain the estimated berthing time to adjust subsequent container pickup and transshipment plans.
Real-time communication with customs brokers: Require them to provide feedback on customs declaration progress every 24 hours (e.g., whether it has been submitted, whether it has been inspected, and the inspection results). If an inspection is required, provide additional information to shorten the inspection time.
Appointments with towing companies in advance: Schedule towing appointments 1-2 days before container pickup/delivery, specifying the “latest arrival time” and “loading and unloading requirements.” This will prevent towing delays due to unscheduled arrivals or subsequent orders being delayed due to loading and unloading delays.
III. Risk Management: Reduce Losses Caused by Congestion
- Purchase Demurrage Insurance or Delay Insurance
Port congestion often results in two types of additional costs: vessel demurrage (fees charged by shipping companies to shippers for vessel waiting, typically calculated on a daily basis and potentially reaching thousands of dollars per day during peak season); and inland demurrage (fees charged by container yards for overdue container usage). Risks can be transferred through insurance:
Purchase Marine Demurrage Insurance: Some insurance companies offer this type of coverage. If demurrage is incurred due to port congestion, reimbursement will be provided at an agreed-upon rate (note the “exclusions” in the insurance terms; for example, demurrage caused by errors in the shipper’s documentation will not be covered).
Cargo Delay Insurance: If the cargo is a rush order (such as holiday gifts or production materials), purchase Delay Insurance. If congestion causes a delay exceeding the agreed-upon time (e.g., 7 days), compensation (e.g., 10%-20% of the cargo’s value) will be provided to cover losses from customer default or production downtime.
- Clarify Contractual Liabilities and Compensation Clauses
Contracts with customers, carriers, and logistics service providers should include pre-existing provisions regarding port congestion liability to avoid subsequent disputes:
Consult with customers: Include a “port congestion exemption clause” in the sales contract, stating that if delivery is delayed due to force majeure (such as port congestion), the delivery period may be appropriately extended without liability for breach of contract. (Note that this clause must comply with international trade practices, such as the United Nations Convention on Contracts for the International Sale of Goods.)
Consult with carriers: Specify the scope of demurrage liability in the transportation contract. For example, stipulating that “demurrage due to the carrier’s failure to book a container in a timely manner shall be borne by the carrier” or “demurrage due to sudden port congestion shall be shared proportionally by both parties.” This prevents the carrier from unilaterally shifting all costs.
Consult with trucking/warehousing companies: Specify the “overdue fee calculation criteria” (such as a cap on the fee for overdue container pickup) to prevent the service provider from arbitrarily increasing prices.
- Monitor cargo status in real time and respond promptly to any anomalies.
During congestion, cargo status may change at any time (e.g., ships relocate to new ports or container storage locations change). Real-time tracking is essential through tools:
Use the “Ship Tracking Tool” to check the ship’s real-time location and estimated arrival time. If a ship deviates from its original schedule, promptly confirm the reason with the carrier.
Use the “Container Tracking System” (e.g., container tracking function on shipping company websites or logistics platforms) to check container status (e.g., whether it has been unloaded, released, or is in the storage yard). If a container is “overdue,” promptly coordinate a trailer to pick it up to avoid incurring high storage fees.
If a shipment is delayed, communicate promptly with the customer, explaining the cause of the delay, the estimated time to recovery, and offering alternative options (e.g., prioritizing transshipment of some cargo) to mitigate customer dissatisfaction and maintain a positive relationship.
