Demurrage refers to the charges applied when cargo remains at a port or terminal beyond the allotted free time. These fees are crucial in maritime logistics, as they incentivize timely loading or unloading of goods. Demurrage rates vary based on factors like the type of cargo and the agreed-upon terms between the parties involved. Typically, demurrage charges accrue per day after the free time expires. It's essential for businesses engaged in shipping to manage their logistics efficiently to avoid incurring substantial demurrage costs. Understanding what demurrage is and proactively managing cargo timelines can significantly impact a company's bottom line by preventing unnecessary expenses associated with delayed shipments.

Detention in shipping pertains to the charges imposed when containers or equipment are retained beyond the allowed timeframe for loading or unloading. These detention charges are distinct from demurrage and are incurred when the containers are utilized for storage purposes or are held due to delays caused by the consignee or other logistical factors. Detention rates vary depending on the shipping line and the terms agreed upon. Efficient planning and coordination between parties involved in the logistics chain are crucial to minimizing detention charges. By understanding what detention is and optimizing cargo handling timelines, businesses can mitigate additional costs associated with prolonged container retention.
