A shipper or consignee encounters demurrage at the seaport the moment a container overstays its contractual free time at the terminal. The daily charges—levied by the shipping line or terminal operator—are designed to encourage rapid turnover and offset the cost of occupied yard space. Common triggers include delayed customs clearance, missing import documents, or slow collection arrangements. Demurrage applies while the container remains inside the terminal; once it leaves the port, any further delay in returning the empty box falls under detention, a separate charge that should not be confused with demurrage.
