Demurrage is a term we encounter in e-commerce. Demurrage is the fee charged by the container line when containers are not picked up on time during international shipments. In this article, we have provided information on the concept of demurrage across various types of logistics transportation.

What Is Demurrage?
Demurrage is the fee charged for each day the time allotted for containers at the port is exceeded. Shippers begin accruing this fee starting the day after the final day of the allotted time, and it is calculated on a per-container, per-day basis until the container is picked up. Demurrage applies to e-export transactions conducted via maritime transport.

Who Pays the Demurrage?
The concept of demurrage arises in e-commerce. In international trade transactions, it refers to the additional fee paid for goods when the specified transit time between the buyer and seller is exceeded. When we ask “Who pays demurrage?”, the customer who fails to return the container within the agreed-upon timeframe pays it to the company that owns the container.
What are detention charges?
In e-export transactions, the buyer and seller agree on the transportation of the cargo. These agreements include provisions such as the delivery of the container and the shipment of the goods to the port. Loading and unloading times are determined by the parties’ agreements. If the timeframes specified in the agreement are exceeded, detention charges apply. When demurrage charges arise, the amount of this fee is also specified in the agreement. This fee is determined by the container company. The fees vary for each e-export shipment. These fees are determined based on the weight, size, and destination of the transported goods, as well as the destination country.
When Does Demurrage Apply?
Demurrage applies when the time specified in the contract is exceeded. Shipments arriving by air or rail are granted a 48-hour free storage period. However, this period can vary from approximately four to seven days at ports. Since all entry ports have their own policies, it is important to be aware of demurrage policies along your container’s route.
What Are the Causes of Demurrage?
Demurrage charges may be related to delays, but they can also result from issues such as missing documents, documents not reaching the company on time, or documents being lost. For this reason, the shipper may be subject to demurrage charges even for reasons beyond their control. Below, we have listed some situations that may lead to demurrage:
- A dispute arose between the shipper and the consignee.
- The consignee (the person receiving the goods) is unaware of the shipment’s arrival time/date, resulting in the product not being picked up on time.
- The documents received by the consignee are incorrect or incomplete.
- The received shipment does not match the sales order.
- Issues arising during container customs clearance.
Why Demurrage Costs Matter
Demurrage charges are not just extra costs. They can cause bigger problems throughout the supply chain, especially for businesses that ship goods often.
When shipments are delayed for too long, it can lead to several issues:
- Increase safety risks: Extended delays keep drivers on the road longer and may increase accident risks.
- Reduce transportation capacity: Trucks and drivers stuck waiting cannot complete other deliveries.
- Damage business relationships: Frequent delays can affect trust between shippers, carriers, and logistics partners.
- Create compliance issues: Longer waiting times may make it harder for drivers to meet Hours-of-Service requirements.
- Impact driver satisfaction: Repeated delays can lead to frustration and higher driver turnover.
- Increase fuel waste: Idling trucks consume more fuel and create unnecessary emissions.
For companies that move a lot of freight, even small delays can add up to high costs. Making pickup and delivery more efficient is one of the easiest ways to cut down on demurrage fees.
Ways to Cut Demurrage Costs
Costs also come into play in international shipping. Demurrage charges vary by carrier, terminal, and contractual agreement. While demurrage charges are very common and often unavoidable, there are a few ways to avoid incurring them. Below, we have listed ways to avoid demurrage costs:
- Plan Ahead: Arrange shipments early to secure carriers and avoid unnecessary delays.
- Have a Backup Plan: Prepare alternative solutions to handle unexpected issues and reduce extra charges.
- Follow Requirements: Provide accurate shipment details and follow delivery instructions to prevent delays.
- Request Extra Free Time: For sensitive cargo, additional free days can provide flexibility during unexpected delays.
- Understand Customs Rules: Knowing port and customs procedures helps avoid clearance problems and additional costs.
