Demurrage & Detention: How to Avoid Extra Charges

Demurrage and detention are charges imposed by ocean carriers and terminals when containers aren't moved or returned within the allotted "free time." Together, they can add hundreds—or thousands—of dollars per container to your import costs.

Demurrage vs. Detention

• Demurrage: Charges for a container sitting at the port terminal beyond free time. Typically 4–7 free days after vessel discharge.
• Detention: Charges for keeping the container (equipment) beyond free time after it leaves the terminal. You're charged for the time it takes to unload and return the empty container.

What Causes These Charges?

• Late customs clearance — If your entry isn't filed before vessel arrival, the container sits unclaimed
• CBP examination — Containers selected for exam can be held for days
• FDA or USDA holds — Agency detention pending documentation or lab results
• Missing documents — Incomplete commercial invoices, missing permits
• Warehouse scheduling issues — No appointment available to receive goods

How to Avoid Them

• Pre-arrival entry filing — File your customs entry 5+ days before vessel arrival
• Complete documentation — Send all documents to your broker immediately
• Pre-arrange delivery — Schedule trucking and warehouse appointments before arrival
• Use an experienced broker — Brokers who specialize in your commodity know how to prevent PGA holds
