At Stile Associates, we believe education is key to smarter importing. One of the most confusing and expensive pitfalls shippers face is demurrage charges. If you’re unsure how these fees work, why they happen, or how to avoid them, this comprehensive guide is for you.
1. What Are Demurrage Charges?
Demurrage charges are penalty fees charged by carriers or terminals when a container stays too long at the port after it’s available for pickup.
These charges begin after your “free time” expires, usually 3 to 7 days, and are applied per container, per day.
Example:
If your container sits at the port for 4 days past its free time and the demurrage rate is $150/day, you owe:
→ $150 x 4 = $600 per container
2. How Does Demurrage Work in Real Life?
After your container is offloaded at the port, you’re granted a grace period (called free time). During this time, you must:
- Clear your goods through customs
- Schedule pickup with a trucker
- Move it to a warehouse or your final destination
If any delays happen, and the container is not moved on time, you pay a daily charge until it’s gone.
3. Why Do Demurrage Charges Exist?
Terminals are under pressure to keep containers flowing. They charge demurrage to:
- Discourage congestion
- Incentivize quick container removal
- Recover space and equipment costs
Think of it like parking in a spot for too long without paying, you’ll get a fine.
4. Who Pays for Demurrage?
Usually the importer.
Even if you’re working with a freight forwarder or broker, you are responsible for clearing and moving your cargo. If you miss your window, demurrage is your bill.
This is where working with a proactive partner like Stile Associates can help prevent charges before they start.
5. How Are Demurrage Charges Calculated?
Here’s the standard formula:
Demurrage = Rate × Number of Containers × Extra Days
Example (Realistic):
- Free days: 5
- Containers: 2
- Rate: $125/day
- Delay: 3.5 days
$125 × 2 × 3.5 = $875
⚠️ Some terminals use tiered pricing:
- Days 11+ = $200+/day
- Days 1–5 = $100/day
- Days 6–10 = $150/day
6. Why Demurrage Charges Happen
Common causes include:
- Customs clearance delays (missing documents, wrong HTS codes)
- Missed truck pickup or lack of chassis
- Paperwork not filed in time (e.g., Bill of Lading, Importer Security Filing)
- Weather or port congestion
- Terminal operating issues
7. Demurrage vs. Detention vs. Port Storage: What’s the Difference?
| Term | What It Means | Where It Happens |
| Demurrage | Container stuck at the terminal after free time | Port terminal |
| Detention | Container picked up but not returned in time | Off-terminal |
| Port Storage | Fees charged by the port (separate from carrier) | Port Terminal |
Important: You may be charged both demurrage and detention!
8. How to Avoid Demurrage Charges (Smart Importing Tips)
At Stile, we help our clients implement these prevention strategies:
Pre-Clear Documents
Submit paperwork before vessel arrival: commercial invoice, packing list, ISF, etc.
Use a Trusted Customs Broker as Stile.
We manage compliance, HTS codes, and classification for a smooth release.
Track Containers in Real-Time
We monitor arrival, free time, and coordinate delivery before deadlines.
Schedule Trucking Early
Have truckers on standby and confirm container availability.
Negotiate Free Time
When possible, ask the steamship line for extra days, especially for high-volume shipments.
Stay in Constant Communication
We keep you updated at every stage, so you’re never caught off guard.
9. The Cost of Ignoring Demurrage: A Cautionary Example
Imagine 10 containers delayed 7 days at $150/day:
→ $150 x 10 x 7 = $10,500
Now imagine your cargo is only worth $9,000.
You’ve lost money before even selling your product.
10. Key Considerations Before You Ship
- Know your port’s free time policies
- Understand terminal-specific fee structures
- Confirm your incoterms (DAP vs. DDP matters)
- Work with a logistics partner who keeps things moving
