Detention

What is Detention in Shipping?

Detention refers to charges incurred when a container remains with a shipper or consignee beyond the free time allowed by the carrier. It typically applies after the container has been collected from the terminal and continues until the empty unit is returned (or, in some cases, until export loading is completed and the container is gated back in). The aim is to encourage timely turnaround and keep equipment available across the supply chain.

How Detention Charges Work

Carriers provide a defined free-time window for loading, unloading, and returning the container. Once that period expires, detention charges accrue based on the carrier’s tariff, commonly charged per container per day. Clear coordination between transport, warehouse teams, and the carrier helps avoid preventable cost build-up.

Common Causes

  • Poor scheduling: Misalignment between pickup, warehouse readiness, and return windows.

  • Labour shortages: Limited labour delaying loading or unloading.

  • Volume congestion: Yard or warehouse congestion slowing container turnaround.
