Detention Charge — Return Deadlines and Cost Management for Import FCL Containers
Interlink編集部What Is Detention?
Detention refers to charges incurred in import FCL cargo operations when an empty container is not returned within a specified period set by the shipping line or NVOCC after the container has been gate-out from the CY. In Japanese, it may also be called "detention," container return delay fee, empty container return delay fee, or empty van return delay fee.
In import operations, a container is not only a box for transporting cargo but also transportation equipment owned and managed by the shipping line or NVOCC. Therefore, even after the consignee has removed the cargo, if the empty container is not returned by the specified deadline, charges may arise as the container is considered to be occupied beyond the allowed time.
Detention charges apply after the container has been gate-out from the CY. The management responsibility spans from after cargo pickup, the unstuffing at the delivery destination, until the empty container is returned to the designated return location.
In practice, Detention should not be viewed simply as an additional fee. It is necessary to review chronologically the CY gate-out date, Free Time, unstuffing schedule, return reservation, return depot, drayage arrangement, empty container return date, and the basis for invoices from the shipping line or NVOCC.

Differences between Demurrage, Detention, and Storage
Costs that are often confused with Detention include Demurrage and Storage. All of these relate to the retention of containers or cargo, but they differ in terms of where they occur, the applicable period, the billing party, and the documentation used for verification.
In simple terms, Demurrage is the cost incurred when cargo cannot be moved out of the CY, Detention is the cost incurred when empty containers cannot be returned after leaving the CY, and Storage relates to costs associated with storing cargo or containers at terminals, warehouses, or similar facilities.
| Item | Demurrage | Detention | Storage | Key Practical Points for Verification |
|---|---|---|---|---|
| Main Location of Occurrence | Within CY or terminal. | On consignee’s side after CY gate-out, delivery locations, warehouses, or storage locations before return. | Terminal, warehouse, bonded area, storage facility. | Confirm where the cargo or container is retained. |
| Subject | Fully loaded container. | Empty container after cargo is discharged. | Cargo, container, or storage space. | Distinguish whether it is a loaded or empty container, and identify the storage subject. |
| Typical Start Point | After vessel discharge, after free storage period ends, etc. | Based on the CY gate-out or container pick-up date. | After in-gate or storage start, following free storage period expiration. | Confirm which date the cost calculation begins from. |
| Typical End Point | The day the container is moved out from the CY. | The day the empty container is returned to the designated return location. | The day the cargo or container is moved out from storage. | Confirm the date when charges stop. |
| Main Causes | Customs clearance delay, delay in D/O arrangement, insufficient pick-up reservation, consignee-related reasons. | Delay in devanning, insufficient return reservation, depot congestion, delay in drayage arrangement. | Delay in outward movement, warehouse retention, customs delay, storage location circumstances. | Break down causes chronologically. |
| Documents for Billing Verification | Vessel arrival date, discharge date, free time period, pick-up date. | CY gate-out date, devanning date, return deadline, empty container return date, Equipment Interchange Receipt (EIR). | In-gate date, storage start date, outward movement date, warehouse details. | Cross-check billing periods against actual handling. |
| Common Areas of Disputes over Responsibility | Who is responsible for delays in customs, D/O, or pick-up arrangements. | Whether delays in empty container return are due to consignee reasons or return location/arrangement issues. | Whose instructions or circumstances caused continued storage. | Focus on delay causes and communication records rather than outcomes. |
Common Misunderstandings
Detention is often confused with Demurrage, or misunderstood as a charge that stops once unloading is completed. In practice, management is required until the empty container is returned to the designated return location.
| Misunderstanding | Actual Concept | Possible Issues |
|---|---|---|
| Detention is the same charge as Demurrage | Demurrage mainly applies before CY gate-out, while Detention relates mainly to delays in returning empty containers after CY gate-out. | Misidentifying the billing period may lead to incorrect attribution of causes and responsibility allocation. |
| Detention stops once the cargo is discharged | In many cases, charges continue until the empty container is returned to the designated return location. | Underestimating arrangements for container return after discharge completion can result in additional costs. |
| No shipping line charges apply if the delivery location is just busy | If the return of the empty container is delayed due to circumstances at the delivery location, Detention charges may apply. | The cargo owner may not anticipate bearing costs, leading to disputes upon billing. |
| If no return appointment can be made, the charge is automatically waived | Even if return appointments are unavailable, waivers or reductions require documentation and negotiation. | Failure to keep records of booking screens, depot responses, and communications may prevent proper explanation. |
| The cargo owner is not responsible if the return depot is congested | Depot congestion is considered, but early arrangement and confirmation of alternative return locations are also evaluated. | It may be difficult to demonstrate who made return reservations or confirmations and when. |
| The consignee is not involved since the freight forwarder handles arrangements | If delays are caused by the consignee’s unloading delays, delivery site circumstances, or prolonged inspections, the consignee may be held responsible for costs. | Cost burden disputes may arise between the consignee and freight forwarder after charges are incurred. |
| Charges stop once the empty container is dispatched to the return location | The effective date is often when the return is officially accepted, not when the container is sent. | Gate closings, acceptance refusals, or booking errors may cause the return to be incomplete. |
| If there is Combined Free Time, Detention is not an issue | Even with Combined Free Time, charges may incur if the total free period is exceeded. | Misunderstanding the boundary between Demurrage and Detention can lead to errors in managing remaining free days. |
Typical Situations Where Detention Becomes an Issue
Detention requires confirming not only the delayed return of empty containers but also the underlying reasons why the return was not possible. The main causes can be categorized into those related to the consignee side, the freight forwarder or drayage arrangement side, and the shipping line, NVOCC, or return depot side.
| Case | Common Issues | Documents to Check | Practical Response |
|---|---|---|---|
| Delay in Unpacking (Devanning) Operations | Cannot unload cargo to empty the container, causing the return deadline to be exceeded. | Delivery schedule, devanning schedule, work records, warehouse communication logs. | Compare the earliest possible devanning date with the container return deadline to confirm if it is due to consignee circumstances. |
| Delivery Location Unable to Accept | Warehouse congestion, lack of reservation, or holidays prevent container acceptance. | Delivery reservation records, warehouse responses, delivery instructions, holiday information. | Verify the timeline to determine whether the cause is the delivery location’s situation or delay in arrangements. |
| Prolonged Inspection and Quantity Confirmation | Cargo inspection is not completed, so the container cannot be emptied. | Inspection records, damage confirmation records, quantity confirmation records, cargo owner communications. | For cargo requiring inspection, share the container return deadline in advance. |
| Inability to Book Return Reservation | Although the empty container is ready for return, the return depot’s reservation slots are insufficient. | Return reservation records, reservation screens, depot responses, drayage company communications. | Record the date and time when the reservation attempt was made and alternative measures taken. |
| Return Depot Congestion or Reception Restrictions | Return is not possible due to congestion, limited reception hours, or restrictions on applicable containers. | Depot guidelines, reception conditions, congestion notifications, return rejection notices. | Confirm with the shipping line or NVOCC about changing the return location or possible extensions. |
| Delayed Notification of Return Location Change | The return depot was changed, but notification to stakeholders was delayed. | Shipping line or NVOCC notices, freight forwarder communications, drayage instructions. | Confirm who became aware of the change, when, and to whom the information was communicated. |
| Insufficient Drayage Return Vehicle Arrangements | After devanning, trucks or chassis cannot be secured, delaying the return. | Drayage arrangement records, vehicle arrangement status, return instructions, dispatch responses. | Manage return vehicle arrangements simultaneously with delivery arrangements. |
| Impact of Holidays, Consecutive Holidays, and Severe Weather | Insufficient business days, port congestion, and post-typhoon confusion reduce available return slots. | Calendars, port operational information, weather records, depot reception details. | Check whether calculations include holidays or are based on business days. |
Who Is Responsible for the Costs Incurred?
The most contentious issue regarding detention charges is determining who bears the cost. It cannot be automatically concluded that the consignee, freight forwarder, drayage company, shipping line, or NVOCC is responsible merely because the return was delayed.
If the delay in return is caused by the consignee’s side—for example, delayed devanning, warehouse issues, late delivery appointments, inspection arrangements, or shortage of workers or forklifts—these circumstances are generally considered to be the consignee’s responsibility.
On the other hand, if the freight forwarder failed to clearly communicate the return deadline, delayed confirming the return booking, made errors in drayage arrangements, or overlooked notifications regarding changes to the return location, the freight forwarder’s responsibility for these arrangements may come under scrutiny.
Additionally, factors related to the shipping line—such as specification of return locations, congestion at the return depot, container positioning logistics, sudden changes to return locations, or restrictions on acceptance of returns—may also affect the situation. In such cases, it is possible that neither the consignee nor the freight forwarder’s efforts alone were sufficient to achieve return, and clarifying cost responsibility requires a detailed chronological review.
CY Gate-Out Date and Empty Container Return Deadline
Key factors for confirming Detention are the CY gate-out date and the deadline for returning empty containers. In many cases, Detention is calculated based on the date the container was taken out from the CY or the date it was picked up, with a set free time period granted.
If devanning is completed and empty containers are returned to the designated return location within that period, no Detention will be incurred. However, if the empty container is returned after the free time has elapsed, Detention charges may apply according to the number of days exceeded.
Rates may increase the longer the delay, and even a few days of delay can result in significant costs if there are many containers. The free time allowed varies depending on the shipping line, NVOCC, trade route, container type, and contract conditions.
It is also necessary to confirm whether weekends and holidays are included, whether the calculation is based on business days, and the exact timing used to determine the return completion date.
Devanning and Detention
Detention is closely related to devanning work performed after CY gate-out. Devanning refers to the process of unloading cargo from a container. This unloading is carried out at delivery warehouses, the consignee’s factory, or designated warehouses.
If devanning is delayed, the container cannot be emptied, causing a delay in returning the empty container. Common reasons include congestion at the delivery site, insufficient unloading personnel, forklift shortages, prolonged inspection work, problems with cargo stowage conditions, damage inspection, and quantity verification.
From the cargo owner’s perspective, it may appear as though "only the cargo inspection is taking time," but from the shipping line’s or NVOCC’s viewpoint, the container return is delayed. Therefore, delays in devanning are a major cause of detention charges.
Return Depot and Return Booking
Empty containers are returned to a designated return location after devanning. This return location may vary depending on the shipping line, NVOCC, container type, port, and operational conditions.
Some return depots may require advance booking. In addition, there may be restrictions on reception hours, holidays, congestion status, and the types of containers that can be returned.
Even if the cargo has been completely unloaded, delays in returning empty containers can occur due to reasons such as being unable to secure a return booking, congestion at the return location, changes to the designated return site, or the specified depot not accepting the container.
In such cases, the issue cannot simply be attributed to the consignee alone. It is necessary to review the designation of the return location, booking status, and the timing of confirmations by the freight forwarder or drayage company.
Drayage Arrangement and Detention
Detention is closely related to drayage arrangements. In import FCL, drayage companies may be responsible for CY gate-out, delivery to the consignee, and the return of empty containers after devanning.
Even if a vehicle is arranged at the time of CY gate-out, if vehicles or chassis for the return are not secured, the return of empty containers may be delayed. This is especially true during busy seasons, around consecutive holidays, periods of port congestion, and after typhoons or severe weather, when arranging return trips can become difficult.
To prevent Detention, it is necessary to manage not only the delivery date but also the planned completion of devanning, return reservations, and the arrangement of return vehicles.
Application Requirements and Exceptions
To determine whether Detention charges apply, do not simply look at the billing title. Instead, verify if the charges relate to the cost of delayed return of empty containers after CY gate-out.
| Category | Requirements to Confirm | Exceptions / Common Issues | Practical Measures |
|---|---|---|---|
| Applicable Cargo | The cargo uses containers from the shipping line or NVOCC, such as FCL cargo. | Cases like LCL cargo or shipper-owned containers where empty container return management differs. | Confirm the container number on the charge and contractual conditions. |
| Start Point | Free time may start from the CY gate-out date or container pickup date. | Incorrectly calculating from vessel arrival date or discharge date. | Check the start point based on the shipping line’s or NVOCC’s tariff and contract terms. |
| End Point | Confirm the date the empty container return is completed at the designated return location. | Mistaking the end point as the devanning completion date or the date the container departed for return. | Verify the return completion date from the EIR or return acceptance records. |
| Free Time | Confirm the number of days the container can be used free of charge. | Confusing free time for Demurrage with free time for Detention. | Check whether these are separately defined or combined free time applies. |
| Days Calculation | Confirm if calculation is on calendar days or working days, and whether weekends and holidays are included. | Misunderstanding that excludes holidays, causing the return deadline to be missed. | Confirm calculation methods with the shipping line or NVOCC. |
| Return Location | Confirm the designated return depot, return reservation, acceptance hours, and conditions. | Trying to return to outdated locations, wrong depots, or depots not accepting the container. | Confirm the latest return location and whether a reservation is needed before returning. |
| Exemption / Reduction Possibility | Check if there are circumstances on the shipping line/NVOCC or depot side that could allow exemption or reduction. | No records of return reservation refusal or depot closure and no explanation available. | Keep reservation records, depot responses, and communications with the shipping line. |
| Responsibility Allocation | Identify whether the delay was caused by the consignee, freight forwarder, drayage company, return depot, or shipping line. | Determining cost liability unilaterally based only on the outcome. | Prepare a chronological timeline and review cause and communication records. |
Documents to Check When Receiving a Detention Claim
When receiving a Detention charge, first confirm the billing period. You need to verify the cost period, how many free days were allowed, the CY gate-out date, and the empty container return date.
It is important not only to recognize the result as a simple “late return,” but to distinguish when the container was ready for return, why it could not be returned, and who caused the delay.
| Document | Contents to Confirm | Main Holder | Notes |
|---|---|---|---|
| Detention Invoice | Billing period, rate, container number, invoicing party. | Shipping line, NVOCC, freight forwarder. | Check it is not mixed with Demurrage or Storage charges. |
| Free Time Terms | Free period, start point, handling of weekends and holidays, rate tiers. | Shipping line, NVOCC, freight forwarder. | Confirm whether contract terms or tariff apply. |
| CY Gate-Out Record | Date container was gate-out from CY. | Terminal, drayage company, freight forwarder. | This may serve as the start point for Detention. |
| Devanning Record | Date cargo was unloaded and container became empty. | Consignee, warehouse, delivery destination. | Check when the container became ready for return. |
| Empty Container Return Record | Date the return was accepted at the depot. | Drayage company, return depot, freight forwarder. | Confirm using EIR or return acceptance records. |
| Return Reservation Record | Date when reservation was attempted and when it was booked. | Drayage company, freight forwarder, return depot. | Keep records of rejection or full capacity situations. |
| Return Location Change Notification | Change of return depot, acceptance restrictions, notices of return refusal. | Shipping line, NVOCC, freight forwarder. | Check the times notifications were received and shared. |
| Communication Records with Consignee | Delivery date, devanning schedule, return deadline notice, delay communications. | Consignee, freight forwarder. | Presence or absence of deadline notices affects responsibility allocation. |
| Drayage Arrangement Records | Gate-out trips, delivery trips, return trips, dispatch status. | Drayage company, freight forwarder. | Check for any delays in arranging return trips. |
| EIR | Container gate-out and return, condition, acceptance records. | Terminal, return depot, drayage company. | Important as evidence for the return completion date. |
4-Point Assessment Checklist
When verifying Detention, confirm the timeline and causes rather than the billed name. Organize and separate the reasons for exceeding the return deadline according to whether they lie with the consignee, arranging party, return depot, or shipping line/NVOCC.
| Confirmation Stage | Contact Party | Items to Confirm | Action if Issues Are Found |
|---|---|---|---|
| At Start of Import Arrangement | Shipping line, NVOCC, freight forwarder | Detention free time, start point, rate, presence of Combined Free Time. | If conditions are unclear, confirm in writing or by email before gate-out. |
| When Adjusting Delivery Schedule | Consignee, warehouse, drayage company | Delivery date, possible devanning date, relation to return deadline. | If the return deadline cannot be met, reschedule the delivery date or return arrangement. |
| At CY Gate-Out | Drayage company, terminal, freight forwarder | Actual CY gate-out date, container number, gate-out records. | If records conflict, verify and correct before billing. |
| When Confirming Devanning Schedule | Consignee, warehouse, delivery destination | Planned devanning date, workforce, inspection plans, cargo condition. | If devanning appears delayed, share return deadline and cost risks promptly. |
| When Making Return Reservations | Drayage company, return depot, freight forwarder | Need for return reservation, reservation slots, reception hours, return available date. | If reservations cannot be made, keep records and check alternative return sites or extension availability. |
| When Changing Return Destination | Shipping line, NVOCC, freight forwarder, drayage company | New return destination, notification timing, sharing to relevant parties. | If notification is delayed, organize who learned what and when in a timeline. |
| When Returning Empty Containers | Drayage company, return depot | Actual return date, reception completion time, EIR, reasons for rejection of return. | If acceptance is refused, record the reasons and rescheduled return plans. |
| Upon Receiving Invoice | Shipping line, NVOCC, freight forwarder | Billing period, rate, counted days, applicable containers. | If there are errors in period or days, request corrections with supporting documents. |
| When Confirming Responsibility Allocation | Consignee, freight forwarder, drayage company, NVOCC | Cause of delay, deadline notifications, return reservations, devanning delays, depot conditions. | Create a timeline table and discuss cost sharing. |
| When Considering Recurrence Prevention | Consignee, freight forwarder, drayage company | Future delivery plans, return reservations, deadline notifications, communication methods. | Review arrangement flows and deadline notification templates. |
Scope of Freight Forwarder's Involvement
In the case of detention, freight forwarders often find themselves in a weaker position in actual practice. While claims may come from shipping lines or NVOCCs, consignees may question, “Why should we pay this?” Since the circumstances of drayage companies and container return depots are also involved, freight forwarders cannot fully control every aspect.
Nevertheless, from the consignee’s perspective, the freight forwarder serves as the main point of contact responsible for the entire import arrangements. Therefore, if there is insufficient notification of return deadlines, inadequate confirmation of return reservations, or lack of coordination with the shipping line or NVOCC, the freight forwarder is more likely to be held accountable.
| Category | Supportive Actions | What Not to Assert Definitively | Practical Response |
|---|---|---|---|
| Free Time Confirmation | Check shipping lines’ and NVOCCs’ detention conditions, calculation starting points, and deadlines. | Guaranteeing that all delay charges will be waived. | Share the confirmed conditions with the consignee promptly and keep records. |
| Return Deadline Notification | Notify the consignee of the empty container return deadlines and when charges will start. | Assuming that consignee’s devanning or inspection will definitely be completed within the deadline. | Clearly state both the delivery date and the return deadline. |
| Return Reservation Confirmation | Confirm return reservation status with the drayage company and container return depot. | Assuming automatic waivers if return reservations cannot be secured. | Record any inability to make reservations and check alternative solutions. |
| Drayage Arrangement | Confirm arrangements for gate-out, delivery, and return transport. | Assuming full responsibility for drayage company’s vehicle shortages or depot conditions. | Make the entire arrangement status, including return trips, visible. |
| Organizing Billing Documents | Organize invoices, EIRs, return records, and communication logs. | Determining that charges are always unjustified or always the consignee’s responsibility. | Create a chronological table and categorize by cause. |
| Responsibility Allocation Discussions | Share information among consignee, NVOCC, shipping line, and drayage company. | Unilaterally deciding contractual responsibility or ultimate liability. | Discuss based on contract terms, notification records, and delay causes. |
Application Scenarios of the System
Here, we organize scenarios where Detention often becomes problematic as separate cases. We identify at which points costs arise and whose circumstances typically cause those costs.
Scenario 1: Delay in Empty Container Return Due to Late Delivery Unloading
After discharging imported FCL cargo from the CY and delivering it to the consignee’s warehouse, unloading may not occur on the scheduled date due to a shortage of warehouse staff or forklifts. Since cargo remains inside the container, the empty container cannot be returned, resulting in exceeding the Detention free time.
From the shipping line or NVOCC’s viewpoint, the container remains occupied on the consignee side. Even if the cargo owner considers it merely a warehouse delay, exceeding the container return deadline can lead to Detention charges.
In practice, the delivery date, planned unloading date, actual unloading date, and empty container return date are organized chronologically. It is also confirmed whether the freight forwarder had notified the return deadline in advance and whether the consignee was aware of the delay risk.
Scenario 2: Exceeding Return Deadline Due to Failure to Secure a Return Reservation
Even if cargo unloading was completed within the deadline, empty container return may be delayed because the return depot reservation slot cannot be secured. Causes can include port congestion, busy seasons, the period around holidays, or return depot acceptance restrictions.
In this case, it cannot be simply regarded as a consignee unloading delay. However, cost liability assessment depends on when the return reservation was attempted, whether there are records of reservation denial, and whether alternative return locations were considered.
In practice, records such as the return reservation screen, responses from drayage companies, shortage or congestion notifications from the return depot, and confirmations with the shipping line or NVOCC should be retained. It is necessary to be able to explain not only the fact that the reservation could not be made but also what the parties involved did to meet the return deadline.
Scenario 3: Disputes with Consignee Due to Insufficient Guidance on Return Deadline
Even if the freight forwarder shared the delivery date and customs clearance schedule, if the empty container return deadline or the Detention start date was not clearly communicated to the consignee, the consignee might claim after billing, “We were not informed of these costs.”
Detention charges are costs that can be difficult for consignees to foresee. They may assume that import procedures end once the cargo arrives and may not recognize the ongoing cost risk until the empty container is returned.
In practice, when informing the consignee of the delivery schedule, the desired unloading completion date, empty container return deadline, and the potential for Detention charges if exceeded should be clearly stated. Records such as emails or chats should be kept to enable explanation after costs are incurred.
Scenario 4: Misunderstanding Remaining Days of Combined Free Time
Instead of separate conditions for Demurrage and Detention, some agreements manage them together as Combined Free Time. In this case, the days a full container stays at the CY and the days from CY gate-out to empty container return are totaled and consumed against the free period.
For example, if the Combined Free Time is 7 days and 5 days were used inside the CY, only 2 free days remain for the empty container return after CY gate-out. Misunderstanding this can lead consignees to mistakenly believe that “ample free time remains after gate-out.”
In practice, it is essential first to confirm whether free time is separated for Demurrage and Detention or managed as Combined Free Time. The remaining free days as of CY gate-out should be shared to reorganize the unloading and return schedule accordingly.
Practical Preventive Measures
To avoid Detention, it is necessary to confirm the free time and the empty container return deadline early in the import arrangement process. It is important to clearly inform the consignee not only of the delivery date but also of the planned completion date for devanning and the empty container return deadline.
In particular, during holidays, consecutive holidays, warehouse congestion, warehouses with delivery reservation systems, cargo requiring inspection, heavy cargo, or special cargo, schedule management with more margin than usual is required.
Additionally, it is necessary to check whether reservations are required for the return depot, permitted return times, the possibility of changing the return location, and the acceptance conditions at the return location. Returning the empty container is not a post-handling step after unloading the cargo but a residual cost risk remaining at the end of the import FCL arrangement.
Practical Meaning of Detention
Detention is not simply an additional charge. In import FCL, it arises as a consequence of poor coordination among the consignee, freight forwarder, shipping line, NVOCC, drayage company, and the return depot.
Since empty container returns are the final step in import operations, problems are often difficult to rectify, leaving only the cost claims outstanding.
In freight forwarder practice, Detention should not be treated merely as a shipping line fee; it requires comprehensive management including prior notification, deadline tracking, return documentation, and root cause analysis.
Summary
Detention refers to the charges incurred when an import FCL container is taken out of the CY but the empty container is not returned within a specified free time period.
While Demurrage applies to charges arising before leaving the CY, Detention occurs after leaving the CY, covering the period from unloading cargo to returning the empty container. Detention differs from Storage fees, as it does not relate to the storage of cargo or containers but primarily concerns delays in returning empty containers.
In practice, it is necessary to check the CY gate-out date, cargo unloading date, return deadline, return reservation, return depot, and actual empty container return date, then organize these events chronologically to identify where delays occurred.
To avoid Detention charges, managing not only the delivery date but also the planned cargo unloading completion date and the empty container return deadline is crucial. If charged, it is essential to review free time allowances, return records, reservation status, depot conditions, and communication with the consignee before making a judgment on responsibility.
