Demurrage Charges: How They Impact Your Shipping Costs

India’s major ports, including Nhava Sheva and Mundra, serve as crucial gateways for exporters dealing in textiles, spices, electronics, and various other goods. However, unforeseen costs such as demurrage charges can significantly affect profitability if not properly managed. Understanding the concept of demurrage is vital for businesses involved in international trade, as these fees are typically linked to delays in container movement and can substantially increase overall shipping costs.
This blog aims to clearly explain the meaning of demurrage, how these charges are applied, and their implications for Indian importers and exporters. Whether you are a small trader in Chennai or a large-scale manufacturer in Delhi, understanding and managing demurrage and related charges such as detention can help you control expenses and enhance logistics efficiency.

What Are Demurrage Charges?
Demurrage charges are fees imposed by shipping lines when containers remain at a port or terminal beyond the agreed-upon free time. This period usually ranges from three to seven days depending on the terms outlined in the port or carrier agreement. These charges are intended to encourage importers to collect their cargo promptly and to deter exporters from delivering containers to the port too early. This helps maintain the efficiency of port operations.
For example, if an electronics importer based in Bangalore leaves a container at Nhava Sheva port for ten days when only five days of free time are allowed, demurrage charges will be applied for the five additional days. According to a 2023 report by Container xChange, global demurrage and detention fees rose by 104% between 2020 and 2021. Indian ports such as Mundra have experienced similar trends due to increased congestion.
Understanding the difference between demurrage and other related fees is essential for effective logistics and cost planning.
How Do Demurrage Charges Work?
Demurrage is directly related to how long a container stays within the port premises. The process typically involves the following steps:
Step 1: Container Arrives at the Port
For importers, containers arrive at the port after being offloaded from a vessel. For exporters, containers are delivered to the port for future loading. From this point, the free time starts, which usually ranges between three to seven days, as specified in the shipping contract.
Step 2: Free Time Expires
If the importer fails to clear and remove the container within the free time, or if an exporter delivers the container too early, demurrage charges begin to accrue. For instance, if an importer in Delhi has a container at Chennai port and does not clear it within the five-day free window, charges will be applied from the sixth day onwards.
Step 3: Charges Are Imposed
Shipping lines charge demurrage on a per-container, per-day basis. These rates typically range between ₹5000 and ₹20000, depending on the port, shipping line, and terms of the contract. For example, if an exporter in Kolkata leaves two containers at Mundra port for three additional days, and the charge is ₹10000 per container per day, the total payable amount would be ₹60000.
Step 4: Charges Must Be Paid to Release Cargo
Importers are required to pay demurrage charges before they can retrieve their cargo. Exporters also need to settle any applicable fees to avoid further penalties. Delays in payment can escalate the charges even more.
Demurrage and Detention: Understanding the Difference
Understanding the distinction between demurrage and detention charges is vital for efficient logistics management. Although both are related to delays, they apply under different circumstances. The following table outlines the key differences:
| Factor | Demurrage | Detention |
| Definition | Fees for containers left at the port beyond the free period | Fees for holding containers outside the port beyond the free period |
| Location | Inside the port or terminal, such as Nhava Sheva | Outside the port, for example at a warehouse in Pune |
| Free Time | Generally three to seven days, depending on the port | Typically three to five days, depending on the shipping carrier |
| Applies To | Importers (for delay in clearing cargo) or exporters (for early delivery) | Importers (during unloading) or exporters (during container loading) |
| Typical Cost | ₹5000 to ₹20000 per day per container | ₹3000 to ₹10000 per day per container |
| Example | An importer in Chennai pays for containers left at the port after free time | An importer in Bangalore pays for keeping an empty container too long at a warehouse |
This comparison helps businesses make informed decisions to avoid unnecessary expenses from either charge type.
Demurrage Compared to Other Charges
It is also important to differentiate demurrage from other types of charges:
- Demurrage vs Damages: Demurrage refers to a fee for delay, not for physical damage to goods. Damages, on the other hand, relate to compensation for cargo that is lost or harmed.
- Demurrage vs Port Storage: Demurrage is charged by shipping lines for containers that belong to the carrier. Port storage charges are levied by the terminal and apply to all cargo, with different rules regarding free time.
How Are Demurrage Charges Calculated?
Demurrage charges are based on two main factors: the daily rate and the number of days the container exceeds the free period. The rates differ based on location, shipping carrier, and the type of container involved.
Formula to Calculate Demurrage Charges:
Demurrage Charges = Daily Rate × Extra Days × Number of Containers
Example:
An importer in Hyderabad leaves three containers at Chennai port for four days beyond the permitted five-day period. If the daily rate is ₹10000, the total demurrage charge will be:
₹10000 × 4 days × 3 containers = ₹120000
Some ports may apply escalating rates. For instance, ₹5000 per day for the first three days, and ₹10000 per day thereafter. It is essential to review contracts carefully to avoid unexpected costs.
Strategies to Avoid Demurrage Charges
Indian businesses can reduce demurrage charges by adopting the following strategies:
- Pre-Clear Customs: Ensure all documentation is accurate and submitted in advance. According to FICCI 2023, 70% of shipping delays are related to documentation.
- Negotiate Additional Free Days: Especially at busy ports such as Mundra, request extended free time in the shipping agreement, as suggested by Maersk.
- Use Reliable Transportation Partners: Work with dependable ground transport providers to ensure timely pickup and return of containers. This accounts for approximately 80% of logistics efficiency.
- Utilise Shipper-Owned Containers (SOCs): Investing in SOCs can eliminate carrier-related demurrage fees and result in long-term savings of up to 20%, as per Container xChange 2023.
- Monitor Port Activity: Use digital platforms like FourKites to track weather conditions and congestion, which can help avoid delays in about 60% of cases.
Who Is Responsible for Paying Demurrage and Detention Charges?
Responsibility for demurrage and detention charges typically depends on the shipping agreement and the applicable Incoterms. Importers generally pay demurrage for delays in collecting imported goods, while exporters may be responsible when containers are delivered too early. Detention charges are often borne by the party that holds the container outside the port.
For example, under the CIF (Cost, Insurance, and Freight) term, the exporter might be responsible for demurrage at the port of origin, while the importer would cover such charges at the destination port. These terms are clearly outlined in contracts and shipping guidelines.

Frequently Asked Questions
Is demurrage a penalty?
Demurrage is not a penalty in the legal sense. It is a fee charged to encourage timely movement of containers and maintain port efficiency. However, due to the high costs involved, it often feels punitive.
How much are demurrage charges per day?
In India, demurrage charges typically range from ₹5000 to ₹20000 per container per day. The actual amount depends on factors such as the port, shipping line, and contract terms, based on Maersk’s 2023 data.
What is 14 days of free detention and demurrage?
Some shipping lines may offer a combined free time of 14 days that includes both demurrage and detention. This is uncommon in India, where the standard free time is usually three to seven days, according to Hapag-Lloyd’s 2023 guidelines.
