Two charges with similar names land on different parties and start at different moments. Demurrage accrues when a container sits inside the terminal beyond its free time. Detention accrues when the container has left the terminal but has not been returned empty. On a packaging import both can run at once, and both escalate as the days pass.
Demurrage usually belongs to the party that contracted with the carrier for the carriage – commonly the shipper or the consignee named on the bill, depending on the term and the booking. Detention follows the equipment, so it belongs to whoever holds the container. On an FOB shipment the consignee arranges carriage and holds the equipment, which puts both charges on the buyer’s side. On a CIF shipment the seller arranges carriage but the container is still collected by the buyer, and the split needs reading rather than assuming.
Free time is the buffer, and it is negotiated rather than fixed. Carriers publish standard free days at origin and destination, and forwarders with volume can extend them. Ten days at destination is common, fourteen is achievable on some lanes, and a few days more can be bought. For packaging imports where customs clearance involves document checks or a surprise inspection, the difference between ten and fourteen days is often the difference between a clean arrival and a charge.
The causes on packaging shipments are predictable. Documents arrive after the vessel, so clearance cannot start. A certificate of origin needs correction. Customs selects the container for inspection. The buyer’s warehouse has no space and the container waits for a delivery slot. The consignee’s details on the bill do not match the importer of record. Each is fixable, and each costs money per day while it is not fixed.
Charges escalate rather than accumulate linearly, and the published tariff is only the starting point. Carriers bill per container per day against a schedule that rises in steps, and additional terminal charges can attach to the same delay. A week of detention on a forty-foot container can exceed the freight on a part load, which is why the subject deserves attention before the booking rather than after the invoice.
Disputes are winnable when the cause sits with the carrier or the terminal. A container that could not be collected because the terminal was congested, or because the carrier released the bill late, is evidence-based territory. A container that waited because the consignee had no slot is not. Photographs, timestamped correspondence and the terminal’s own notices are the evidence that decides these arguments.
Prevention is mostly sequencing, and the document side sits inside the pre-shipment check routine. Book the inspection before the vessel arrives. Send the documents ahead rather than with the cargo. Confirm the importer of record and the consignee names on the draft bill. Have a delivery slot booked before the container is discharged. None of these is difficult, and each removes a common cause of a charge.
Consolidation changes the arithmetic. A groupage shipment shares a container, so a delay at one consignee holds the whole box and demurrage can be apportioned in ways that feel unfair. Full container loads give the buyer control of the return schedule, which is one reason packaging buyers move to full loads as volume grows, and container loading and pallet planning covers how that space is used.
Returning the empty container is the other half of the equation, and it is where importers lose money quietly. The depot has limited hours, the trucking company has a queue, and the empty has to be booked in. A container sitting on a chassis outside a warehouse while paperwork is sorted is accruing detention for no commercial reason. Scheduling the return at the same time as the delivery is the simple fix.
Freight terms and payment structure affect who bears the risk but not who can prevent the charge. The party with operational control – usually the consignee – is the one who can act. Where the buyer’s forwarder controls the booking, the buyer should still know the free days and the return process, because the invoice will arrive either way.
This article is general information rather than shipping or legal advice. Free time, tariffs and liability rules differ by carrier, terminal and trade lane, and contracts override general practice. Confirm the terms on your booking with the forwarder or carrier before the shipment sails.
