Protect Your Logistics Budget from Port Storage Penalties
Unforeseen Demurrage and Detention charges can quickly destroy the profitability of a shipment. Whether due to custom delays, lack of trucking capacity, or warehouse bottlenecks, when a container stays past its allotted “free time,” the fees compound daily. Proactive logistics managers move beyond reactive billing and use intelligent calculators to estimate potential costs, track gate-in/gate-out dates, and optimize equipment turnaround.
Key Demurrage & Detention Tool Features
- Proactive D&D Calculation: Estimate potential storage fees by inputting vessel arrival dates, free time agreements, and daily tariff rates to identify high-risk shipments.
- Milestone & Gate-Event Tracking: Monitor exact container gate-in at port (origin) and gate-out at port (destination) times alongside standard ocean track & trace data.
- Exception & Free-Time Alerts: Set up automated email notifications to receive alerts when shipments approach their free time expiry at terminals or inland depots.
- Negotiation Data Hub: Use historical container detention data to negotiate more favorable free time conditions with carriers and terminals during tender seasons.
