Decoding Demurrage and Enhancing Shipping Logistics With AI

International trade and shipping are a complex web of processes, timelines, and regulations. At the heart of this intricate dance lies a notorious adversary: Demurrage. 

Imagine a small business owner who imported a shipment of goods from Shanghai to Rotterdam. The business owner meticulously planned the shipment, ensuring that all documentation was in order and the warehouse was ready to receive the goods promptly. However, when the shipment arrived at the port, it was delayed due to a labor dispute.

The business owner was initially understanding, but as the days turned into weeks, the demurrage charges began to mount. The business owner’s small business couldn’t afford to pay the high demurrage charges, and they began to worry that they would have to file for bankruptcy.

The business owner’s story is not unique. Between April 2020 and March 2023, shipping carriers amassed approximately $12.9 billion in detention and demurrage charges, according to data from the Federal Maritime Commission. It has the potential to wreak havoc on businesses, causing disruptions and financial losses that ripple through the entire supply chain. 

What exactly do we mean by ‘Demurrage’?

Demurrage refers to the charges incurred when a shipping container, once unloaded from a vessel, remains at the port or terminal for longer than the agreed-upon “free time.” Free time is the grace period when shippers can pick up or return containers without incurring extra charges.

Demurrage in the Case of Import 

Your container arrives at the Port of Rotterdam, yet road congestion prevents your truck from reaching the port promptly. Consequently, your cargo container faces delays, leading to it being stranded at the port beyond the allowed free days. At this point, the shipping line enforces demurrage charges until your container is picked up and gated from the terminal. Typically, these charges must be settled before the cargo is retrieved from the port.

Demurrage in the Case of Export

Consider your container awaiting loading onto a vessel at the port of Shanghai. However, due to documentation issues, the container may face delays in boarding the vessel scheduled for departure. Consequently, the container must remain at the port until the subsequent departure. During this period, the shipping line will apply demurrage charges for the storage duration.

How Does Free Time Fit into the Demurrage Dynamics?

Free time essentially represents a specific period during which the use of a container does not trigger any demurrage or detention fees, in addition to the standard freight charges. The exact rates and regulations governing free time may differ depending on the specific contractual agreements and arrangements between customers and shippers/carriers.

The Demurrage Charge is the terminal charge. Generally, the customers sign a one-year contract, and they have the flexibility to negotiate the free days beyond the days available in the standard tariff plans. In the realm of container logistics, the window of “contracted free days” offered for container pick up from the container yard typically spans 3 to 7 days. 

Unveiling Influential Factors That Affect Shipping Operations

Demurrage charges are intricately linked to various factors that can disrupt the smooth flow of shipping operations.

Understanding the Ripples of Demurrage

Demurrage is akin to silent predators, stealthily eroding profit margins and causing operational nightmares. The impact of Demurrage extends far beyond financial woes. 

• Supply Chain Disruptions and Operational Delays: Delays in container retrieval or return can disrupt production schedules, leading to costly downtime and customer deliveries. The operational delays even hit the shipping companies.

High demurrage rates pose a significant burden to shipowners, as they increase the likelihood of unexpected delays in the loading and unloading schedules at ports. These interruptions can significantly impact subsequent schedules at other ports, leading to substantial penalty costs for ship owners. For example, the Suez Canal blockage in March 2021 incurred penalty costs of $400 million USD per hour due to logistics delays. Similarly, elevated demurrage rates can have negative implications for truckers involved in land transport of maritime cargo.

• Increased Costs: Demurrage charges accumulate daily, draining resources and impacting the bottom line. It’s like a ticking financial time bomb.

Between April 2020 and March 2023, data from the Federal Maritime Commission revealed that shipping carriers, including CMA CGM, COSCO, Evergreen, Hapag-Lloyd, Hyundai Merchant Marine, Maersk, Mediterranean Shipping Company, ONE, and Yang Ming, amassed approximately $12.9 billion in detention and demurrage charges. These fees can significantly impact customers’ cash flow and projected expenses, posing substantial challenges.

• Strained Business Relationships: Late deliveries or unavailability of containers can lead to customer dissatisfaction and damage relationships with partners and clients.

• Resource Allocation: Businesses may divert valuable resources to manage Demurrage issues, resources that could be used more strategically.

How do you Avoid Demurrage Charges?

Efficient Documentation: Ensure accurate and timely completion of all documentation. Double-check details to prevent errors that can lead to charges.

Proactive Communication: Maintain open and clear communication with all parties involved in the supply chain, including shippers, carriers, and customs authorities.

Effective Customs Clearance: Streamline customs clearance processes by adhering to regulations and staying informed about changes in customs procedures.

Timely Cargo Pickup: Schedule and execute cargo pickups promptly to avoid overstaying at the terminal. Be aware of the free time allowance.

Optimize Container Use: Maximize container utilization to reduce the risk of demurrage charges. Pick the containers promptly on time.

Weather Monitoring: Keep an eye on weather forecasts and make contingency plans for adverse conditions that may impact shipments.

Financial Planning: Ensure that freight charges are paid in full and on time. Include these costs in budgeting and financial planning.

Port Congestion Awareness: Stay informed about port congestion situations and adjust logistics planning accordingly.

Container Tracking and Visibility: Utilize tracking technology to monitor the location and status of containers, facilitating timely return.

Contractual Clarity: Clearly understand the terms and conditions of contracts, especially regarding free time and charges. Negotiate terms when possible.

Logistics Optimization: Implement efficient logistics strategies to minimize delays and unnecessary container use.

Vendor Management: Work closely with vendors and service providers to align operations and prevent delays.

Data Analytics: Utilize data analytics and historical data to predict and prevent demurrage and detention occurrences. There is hope on the horizon in the form of modern technology and machine learning, which can help mitigate these challenges and pave the way for more efficient and cost-effective operations.
