Meaning
Financial compensation paid by a charterer or cargo owner to a shipping line or terminal operator compensates for exceeding agreed port free time during loading or unloading. A demurrage charge accrues on a per-container or per-vessel daily rate basis when equipment remains on port grounds past contractually stipulated limits. Charges cease once equipment exits port gates or transfers to ocean carriage.
Port Delay
Terminal congestion and delayed customs clearances represent primary operational triggers for these costs. When import documents lack required endorsements, containers sit on ocean terminal docks beyond allowed free periods, causing a demurrage charge to calculate against the importer of record. Port operators enforce strict daily accrual rates regardless of underlying administrative faults.
Tariff Escalation
Daily rates increase progressively under standard carrier contracts to penalize extended terminal storage. Early days accrue base fee rates, while long-stay inventory faces tier escalations that double or triple baseline charges within a single calendar week. Extended delays often exceed the total commercial value of the underlying cargo.
Financial Remedy
Clearing unpaid fees stands as a prerequisite for commercial bill of lading release by ocean carriers. Failure to settle invoices results in cargo liens or eventual inventory auction to satisfy claims.
