How to Secure Container Free Time & Avoid Demurrage Fees
YQN Operation Team
Container free time is the period you can use an ocean container without incurring demurrage or detention fees. Once it expires, daily charges begin—making this window just as important to your total shipping cost as the freight rate itself.
As China’s National Day Golden Week approaches, major ocean carriers have announced special container free time policies concentrated between September 23 and October 14, 2026.
Demurrage vs. Detention: The Core Difference
Demurrage covers the time a container stays inside the marine terminal, with free days for customs clearance and pickup. Detention covers the time after it leaves the terminal, with free days to unload the cargo and return the empty container.
Storage is a separate fee charged by terminal operators for the yard space a container occupies. It is billed independently of carrier container free time. Understanding these differences helps avoid unexpected charges.
How Ocean Carriers Calculate Free Time
Standard container free time typically ranges from 3 to 7 days, depending on the trade lane, carrier, and destination port. During seasonal disruptions or holiday shutdowns, carriers often extend this period to keep gate operations running smoothly.
Carriers generally use five calculation methods: a sliding scale that progressively increases free days by sailing date; a fixed number of extra days for specific gate-out windows; full equipment-fee waivers during designated holidays; early empty-container pickup up to 14 days before vessel cut-off; and vessel-by-vessel approval, assessed case by case for specific service loops.
Carrier Free Time Benchmark: 2026 Golden Week
Carrier approaches vary widely. Maersk, COSCO, and ZIM are using a tiered system based on the Estimated Time of Departure (ETD). HMM, ONE, and Evergreen are offering full fee waivers during specific holiday dates.
Meanwhile, CMA CGM grants a flat 10 calendar days, and OOCL adds 3 extra days. Hapag-Lloyd allows early empty pickup instead of extending days. Yang Ming requires voyage-specific applications for its Ningbo-US routes.
The table below outlines the specific policies across 10 major ocean carriers.
| Ocean Carrier | Applicable Region | Core Free Time Policy | Key Date Window |
|---|---|---|---|
| Maersk | 9 China Export Ports | 8–14 days total (tiered by ETD) | ETD Oct 5–14 |
| COSCO | Mainland China Export | +1 to +7 extra days (all types) | ETD Oct 4–10 |
| CMA CGM | Mainland China Export | 10 calendar days free detention | Pickup Sep 23–Oct 2 |
| Hapag-Lloyd | Mainland China & HK | 7, 10, or 14 days early empty pickup | Cut-off Sep 28–Oct 11 |
| HMM | North China & 4 South Ports | 100% waiver for export laden cargo | Sep 25–27 & Oct 1–7 |
| ONE | Central/North China, Fujian | 100% equipment fee waiver | Oct 1–7 |
| Evergreen | Export Laden Cargo | 100% detention fee waiver | Oct 1–14 |
| Yang Ming | Ningbo (US Lane only) | Base 7 days + 7–9 extra days | ETD Oct 6–10 |
| ZIM | Fuzhou Export only | 10, 12, or 14 days by specific voyage | ETD Sep 30–Oct 10 |
| OOCL | Specific China Regions | +3 extra days | Pickup Sep 25–30 & Cut Oct 4–9 |
Note: Policies for Yang Ming, ZIM, and OOCL are strictly regional or conditional. Because carriers define "extra days" and "total free time" differently, these policies cannot be directly compared side-by-side.
Practical Checklist to Maximize Free Time
Managing container free time requires disciplined operational oversight before releasing cargo from the origin factory. Follow these essential steps:
1. Verify the Trigger Date.
Confirm whether free time counts from empty container release, gate-in, or vessel departure.
2. Distinguish Equipment from Storage.
Carrier free time rarely waives terminal storage or reefer monitoring costs. Confirm terminal tariffs separately.
3. Audit Special Equipment Rules.
Reefer, open-top, and flat-rack containers rarely qualify for standard dry-van extensions.
4. Track Carrier Vessel Omissions.
Switching vessels or routes during port congestion can instantly void negotiated extensions.
5. Archive Official Notices.
Maintain written documentation of carrier policy notices to resolve billing disputes effectively.

FAQ: Container Free Time
Q1: What is the exact difference between Container Free Time and Terminal Free Storage?
Container free time applies to the use of the carrier's equipment once it leaves the port. Free storage covers the physical yard space the container occupies inside the terminal.
Extended equipment free time rarely covers terminal storage costs. Always verify terminal storage fees independently before gating in.
Q2: When does the container free time clock actually start?
The trigger date varies entirely by carrier. Some carriers start counting from the empty container pickup date. Others calculate extensions based on the Estimated Time of Departure (ETD) or FCL cut-off date.
The actual usable days differ significantly based on this starting point. Always check the specific carrier's rule to plan loading schedules accurately.
Q3: Do free time extensions apply to reefers, special equipment, or dangerous goods?
Generally, no. Most carriers restrict extra free time to standard dry containers. Some extensions may include reefers but exclude dangerous goods.
Special equipment like open-tops or flat-racks rarely qualify. Always confirm special cargo free time policies individually before booking.
Q4: If my cargo is rolled to another vessel, do I keep the extended free time?
Not necessarily. Extra free time is often tied to the specific vessel loaded. If your shipment is rolled to a vessel not listed in the waiver program, you may lose the extended free time.
During busy peak seasons, vessel changes happen frequently. Always double-check your free time validity after any booking or vessel update.
Q5: Can I stack holiday extensions with my existing contractual free time?
It depends on the carrier. Some carriers do not allow stacking and will simply apply whichever free time period is longer.
Others will resume normal contractual free time once the specific holiday waiver period ends. Review your service contract terms closely.
Q6: What if my specific ocean carrier has not announced a free time extension?
Carrier policies update frequently, and some release multiple policy versions. If your carrier has not published an official holiday free time notice, never assume extensions apply by default.
Unverified assumptions lead to expensive demurrage bills. Always request written confirmation from the local carrier office or your freight forwarder.
