Demurrage and detention fees are some of the most overlooked yet costly parts of international trade. Failing to manage them properly can result in unexpected charges, strained supply chains, and lost profits.
This guide breaks down these charges in a structured, easy-to-follow format, with FAQs and solutions.
1. What Are Demurrage and Detention?
Demurrage: Charges applied when a container stays at the port or terminal beyond the allowed free time.
Detention: Fees charged when the container is out of the terminal but not returned within the agreed period.
📌 Both are penalties for exceeding free time either inside or outside the terminal.
