Demurrage & Detention: Preventing Costly Container Port Penalties
Demurrage and Detention (D&D) are daily penalties charged by ocean shipping lines for exceeding container free time. Demurrage applies when a container sits inside the port terminal beyond free days; Detention applies when an empty container is held outside the terminal beyond permitted return limits.
Understanding D&D: Comprehensive Technical Analysis
Operational mechanism and commercial application in international freight
Demurrage and Detention are two of the most financially damaging operational risks in container shipping. Ocean shipping lines grant shippers and consignees an agreed number of 'Free Days' (typically 5 to 7 days for standard dry containers, and 3 to 5 days for refrigerated reefers). Demurrage is charged per calendar day for using terminal space while the laden container remains uncollected inside the port. Detention is charged per calendar day while the container is taken outside the port gate to the importer's warehouse until the empty container is returned clean to the carrier's designated depot. In congested ports, combined daily D&D fees can exceed $150 to $300 per container per day.

| Operational Phase | Seller Obligation | Buyer Obligation | Notes & Risk Handover |
|---|---|---|---|
| Negotiation of Free Time | Forwarder (Brosan Lojistik) negotiates 14 to 21 extended free days with carriers | Verifies free-time terms on booking | — |
| Import Customs Clearance Timing | Provides commercial docs before vessel docking | Must clear customs before free days expire | Delays cause demurrage. |
| Container Gate-Out from Port | None | Arranges container drayage out of terminal before demurrage starts | Avoids port storage. |
| Empty Container Restitution (Return) | None | Must return empty container to designated depot before detention starts | Avoids detention fees. |
| Demurrage & Detention Invoice Settlement | Liable if export booking delays occur | Liable for import destination delays | Billed directly by ocean carrier. |
Managing Port Congestion at Ambarlı, Mersin & European Hubs
Authoritative operational insights under Turkish Customs Law No. 4458 & border regimes
Busy Turkish container terminals (such as Kumport and Marport in Ambarlı, or MIP in Mersin) experience periodic customs inspection delays (red line physical checks). If customs holds a container for 10 days while standard free time is only 5 days, the shipper faces automatic demurrage penalties. Brosan Lojistik mitigates this risk by securing extended Combined Demurrage & Detention agreements (typically 14 to 21 free days) through Tier-1 ocean carrier volume contracts.
Key Turkish Export Compliance Points
- •Demurrage = Container inside port terminal beyond free days.
- •Detention = Container outside port terminal beyond free days.
- •Port Storage (ardiye) is charged separately by the port terminal operator, distinct from carrier demurrage.
Common Shipper Mistakes to Avoid
- ⚠️Confusing port storage fees (ardiye paid to port operator) with carrier demurrage (paid to shipping line), leading to unexpected dual invoices.
- ⚠️Failing to inspect the container for pre-existing damage upon terminal pickup, resulting in carrier repair detention deductions upon return.
- ⚠️Delays in courier transit of original bills of lading keeping containers trapped at the destination port past free time.
Preguntas frecuentes for D&D
Direct answers to high-intent questions on responsibilities, costs, and risk
Q1:What is the difference between demurrage and detention?
Demurrage is charged when a full container sits inside the port terminal past the free time. Detention is charged when the container has been picked up from the port but the empty box is not returned to the carrier's depot on time.
Q2:How much free time is standard for container shipping in Turkey?
Standard carrier free time is usually 5 to 7 calendar days for dry containers (and 3 to 5 days for reefers). Brosan Lojistik routinely negotiates 14 to 21 days of combined free time for our clients.
Q3:Does a customs inspection pause demurrage charges?
No. Ocean carriers continue charging daily demurrage even if the delay is caused entirely by customs inspections or government agency holds, unless force majeure waivers apply.
