Why does detention matter?
Detention costs can build up quickly, especially when a trailer sits unloaded at a warehouse because the receiving team is short-staffed or the stock is not ready. Carriers rely on equipment returning on time to serve other customers, so they charge to discourage long holds. For businesses, detention erodes margins and can turn a low-cost road leg into an expensive one.
How does detention work in logistics?
The carrier sets a free-time allowance, often a set number of hours or days, starting when the trailer or container arrives at the site. If the equipment is still on site after that period, the carrier charges detention for each additional day or part day. The receiver can avoid these charges by unloading promptly, arranging a collection, or returning the empty equipment to the depot.
Industries and operations that face detention charges
- Retail store replenishment and receiving
- Warehouse and distribution centre operations
- Food and beverage distribution
- Furniture and home goods importers
- Automotive parts supply
- Construction materials and building supply
- Manufacturing plants receiving raw materials
- Freight forwarding and container logistics
Example in practice
A furniture importer in Gdańsk, Poland has a 40-foot container of sofas collected from the port by a drayage truck and delivered to its warehouse. The contract allows 48 hours of free time for unloading. Because the warehouse’s receiving team is short-staffed, the container sits on site for five days. The carrier charges €75 per day after the free period, so the importer pays €225 of detention. When the empty container is finally collected, the importer also pays for the extra days the container spent in its yard.
