The term "demurrage" refers to a fee charged for the extended stay of containers in maritime transport. This charge occurs when the free time allowed for the use of the container is exceeded, resulting in additional costs for importers and exporters. The aim of this article is to clarify what demurrage is, how it is calculated, and, most importantly, to present effective strategies to avoid this cost, which can significantly impact the profitability of logistics operations. What is the Demurrage Fee? Demurrage refers to the charge for the extended stay applied when a container is not returned within the period agreed upon with the shipping company. This counting begins as soon as the container is unloaded at the destination port. When the stipulated period for the container’s stay within the free time is exceeded, a daily demurrage cost is charged. This fee is calculated daily and represents the additional cost for each extra day the container remains with the importer until the empty container is effectively returned to the shipping company’s designated depot. It is essential to understand that demurrage not only represents a traditional practice in shipping but is also routinely incorporated into transport contracts. Thus, it becomes crucial for the parties involved in the logistics process to understand and efficiently manage this fee in order to avoid undesirable financial impacts, as demurrage is an unexpected cost at the end of the process. How Does Demurrage Work? The demurrage charge starts from the moment the free time expires. Free time is the period agreed upon between the shipper's agent and the client, during which the use of the container does not incur additional costs. This period can vary depending on the negotiation, but in recent times, the average has been from 5 to 14 days, with the possibility of negotiating for longer terms. When the free time ends, the demurrage count begins, and the cost accumulates until the container is returned to the shipping company at the agreed location. The amounts are calculated in foreign currency, usually in dollars, and the charge can be tiered, increasing as the number of delayed days rises. Main Causes of Demurrage Charges Demurrage is applied in various situations of delays in the logistics process. The most common causes include: Delay in Customs Clearance: Problems with the release of cargo by customs, whether due to errors in documentation or by being placed in inspection channels, can delay the retrieval of the container. Congestion at Ports: During peak demand periods, such as holidays (e.g., Christmas or Chinese New Year), congestion at the arrival port can delay logistics operations and result in demurrage charges. Failure in Logistics Planning: The lack of efficient planning for transporting the container and cargo, including the absence of land transport or scheduling issues for cargo pickup, is one of the main causes of extended stays. Delays in Document Release: The regularization of documents, such as the Import Declaration (DI) or the newer Duimp, can take longer than expected, especially when there are issues with licenses, authorizations, and tax payments. Difference Between Demurrage and Detention Demurrage is a daily cost related to the import container charged when you exceed the agreed time from the unloading of the container until its effective return to the shipping company's depot. Detention, on the other hand, is the daily export fine incurred when the free time is exceeded until the full container enters the customs terminal. Therefore, it is crucial to be very careful and precise in monitoring and controlling dates to avoid exceeding the free time. For example, if there is a grant of 5 days for returning the full container after pickup, but the container is returned full in 8 days, this implies the use of 3 extra days, resulting in the application of the detention fee for that excess period. To avoid undue demurrage charges, it is essential that the importer requests the carrier the document for returning the container (exchange/draft). [Online Calculator] How to Calculate the Demurrage Fee and When Is This Fee Applied? As noted, demurrage comes into play when the consignee does not return the empty container within the period agreed upon with the shipping company. In these cases, there is a count of a single period, starting when the container arrives at the unloading port and ending when it is returned empty to the shipping company’s designated depot. The process to calculate the demurrage fee is simple: just multiply the period of the extended stay by the amount stipulated in the contract and in the term of responsibility. This attention to contractual details is essential to avoid surprises and ensure efficiency in the logistics process. Use the calculator below to calculate the demurrage fee:
