A container that sits at a terminal or in a trucker’s yard for a few extra days can cost more than the freight that brought it. For importers and exporters, container demurrage and detention Vietnam exposure is rarely budgeted, usually discovered after the cargo has moved, and often invoiced by a carrier whose tariff the cargo owner never read. The invoice arrives with a deadline, and the carrier may hold the release of the next shipment or the original bill of lading until it is paid.

This article explains where these charges come from, how free time is really counted, what evidence wins or loses a dispute, and how to negotiate or claim back from carriers and terminals. It is written for commercial decision-makers: it ranks the risks, gives checklists and flags where Vietnamese practice must be verified with the competent authority before you rely on it.

Why container demurrage and detention Vietnam charges become a margin problem
Demurrage and detention are two different charges that are routinely confused. In market usage, demurrage is the charge for a loaded container staying inside the terminal beyond the agreed free period, while detention is the charge for a container being held outside the terminal, for example at a factory or warehouse, beyond its free period. Some lines merge the two into a single free time, and terminals levy their own storage charges.
The financial effect compounds quickly. Tariff rates typically escalate in tiers, so the fifth day of delay may cost several times the first. A single congested week can erase the shipment margin, and the clock can start before the importer has even received the documents.
Where the exposure usually arises
- Import side: late bill of lading release, customs inspection or valuation hold, delayed trucking, warehouse not ready, port congestion.
- Export side: early gate-in, rolled bookings, vessel delay or blank sailing.
Who is actually liable for the charge
The carrier will normally invoice the party named in the contract of carriage or the bill of lading, which may be the shipper, the consignee, or a freight forwarder that booked the cargo in its own name. Check who the booking party is before the cargo is shipped, because that party is the first target of any invoice.
The legal basis: contract, tariff and bill of lading
As a matter of international commercial principle, container demurrage and detention Vietnam charges are contractual. They are not a statutory penalty; they are a price for retaining the carrier’s equipment beyond the period priced into the freight. The question in any dispute is therefore whether the charge was validly incorporated into the contract that binds the person being invoiced, and whether it was calculated in accordance with that contract.
In practice the sources are layered. They are usually the booking confirmation or service contract, the carrier’s bill of lading terms, the published shipping line tariff or local charges schedule, and any later written agreement such as an extension of free time. A bill of lading often incorporates the tariff by reference, so the tariff in force on a given date can become part of the contract even though the cargo owner never negotiated it.
What Vietnamese law adds
Vietnam’s Maritime Code 2015 (Law No. 95/2015/QH13, in force since 1 July 2017, with a consolidated text under No. 101/VBHN-VPQH dated 26 August 2025) governs contracts of carriage of goods by sea and the rights of the parties under a bill of lading. It does not, to our knowledge, set a tariff for container equipment charges; the level of such charges is left largely to commercial agreement. Whether a Vietnamese authority regulates, caps or requires publication of particular terminal or container service charges is a point of current practice that must be confirmed.
The draft Maritime and Inland Waterway Code is not adopted as of 14 October 2026 and may change, so re-check the position as it progresses.
Applicable law and forum clauses
Many carrier bills of lading choose a foreign law and forum, often with exclusive jurisdiction or arbitration clauses. For a modest invoice, litigating abroad is uneconomic, so the practical leverage lies in negotiation, in the carrier’s commercial need for the next shipment, and in the quality of the evidence. A Vietnamese consignee should check whether the clause is binding on it and whether local court or arbitration proceedings are realistic. The VIAC rules may be relevant where the parties have agreed arbitration in Vietnam; see the Vietnam International Arbitration Centre for its current procedure.

Free time: how the clock starts, runs and stops
Free time is the period during which no charge accrues. It is the single most negotiable and most misunderstood element of a container movement. The agreed number of days is only half the story; the other half is the event that starts the clock and the event that stops it.
Typical start and stop events
- Import demurrage: often starts on discharge from the vessel, and may stop when the loaded container gates out of the terminal.
- Import detention: often starts on gate-out of the loaded container and stops when the empty container is returned to the nominated depot or terminal.
- Export: detention can start at empty pick-up and stop at gate-in at the loading terminal; storage may begin if the container arrives before the stack opening.
Detention charges and demurrage terms differ by carrier, trade lane and container type.
Calendar days, working days and holidays
A frequent source of dispute is whether weekends and public holidays count. Many tariffs count calendar days, while some count working days only, or exclude specified holidays at the destination. In Vietnam, the Tet holiday period can close customs, depots and truckers for several days while the clock continues. Whether any relief applies must be read from the tariff itself, not assumed.
Practical free time checklist
- Obtain the free time terms in writing before booking, including start and stop events.
- Calendar the final free day for every container, with an internal alert two days earlier.
- Record every container number, gate-in and gate-out timestamp and the source of the record.
Container return and terminal practice
For import cargo, the obligation that most often generates avoidable charges is the container return of the empty equipment. The container belongs to the carrier or its lessor, and the carrier controls where, when and in what condition it must be returned. A closed depot or a rejected empty can extend detention without fault by the consignee.
Return location, depot capacity and damage
The return instruction normally appears in the delivery order or the carrier’s release message. Check that the depot named is open, is accepting that equipment type and size, and is reachable within the time left. If the depot is closed or full, ask the carrier in writing for an alternative before the free time expires, and keep the reply. An equipment interchange receipt, in the market usually called an EIR, records the condition at gate-in and is the main evidence of when and in what state the container was returned.
Terminal storage and the cargo owner’s own costs
Where a container remains inside the port, terminal storage charges may be levied by the terminal operator in addition to the carrier’s demurrage. These are different creditors with different bases, and paying one does not discharge the other. The regulatory framework for port charges, including the published rates and who may collect them, should be checked against the current instruments. Decree 58/2017/NĐ-CP on maritime activity management, as amended including by Decree 14/2026/NĐ-CP, is one of the instruments to review, but the specific charging rules relevant to a given port or service must be confirmed. The Vietnam Maritime and Waterway Administration publishes official information on port and maritime administration.

Demurrage dispute playbook: evidence, notices and negotiation
A demurrage dispute is usually won or lost on documents, not on legal theory. The carrier holds its own system records; the cargo owner needs an independent chronology that shows when the container was available, when it was actually moved and why any delay occurred. Build this chronology as soon as the first invoice or warning arrives.
Evidence to preserve
- Booking confirmation, service contract extracts and any quoted free time.
- Bill of lading, tariff version in force on the relevant dates, and the invoice with its calculation.
- Arrival notice, delivery order release time and any bank or document delay evidence.
- Terminal and trucker records: gate-in and gate-out timestamps, queue messages, EIR.
- All correspondence requesting alternative return or extra free time, with replies.
Grounds that commonly support a reduction
These grounds depend on the contract and facts, and none is guaranteed to succeed. They include carrier-side delay in releasing the cargo or the delivery order, the carrier or terminal failing to accept the empty at the nominated depot, a tariff not incorporated into the contract or not available to the cargo owner, a calculation that counts days that should have been excluded, and a delay attributable to a terminal system outage or force majeure event.
Notice and negotiation sequence
Respond in writing within the invoice’s stated period, denying nothing you cannot support and reserving all rights. Ask for the tariff, the calculation and the underlying timestamps. Offer a without-prejudice settlement where the exposure is real, and request a written release. Where a carrier threatens to withhold cargo or the original bill of lading, consider paying the undisputed part, paying the disputed part under protest, or providing security, rather than letting the delay compound the charge. Check any contractual time limit for disputing an invoice or for claims against the carrier. International sea carriage regimes commonly apply short time bars to cargo claims, and equipment charge disputes may be subject to contractual notice periods in the carrier’s terms.
Risk matrix for importers and exporters
The table below ranks typical exposures, using a simple Fatal, High, Medium or Low scale. The ratings are indicative and should be adjusted to the contract and cargo value.
| Issue | Legal position | Commercial impact | Risk | Mitigation |
|---|---|---|---|---|
| Tariff not agreed at booking | Incorporation by bill of lading may bind the holder | Unbudgeted, escalating daily rates | High | Obtain tariff and free time in writing before shipment |
| Carrier withholds cargo or original bill of lading | Contractual lien or release condition, depends on terms | Delay compounds the charge and may breach the sales contract | Fatal | Pay under protest or provide security; escalate in writing |
| Empty depot closed or full | Carrier controls return instruction | Detention continues without fault | Medium | Request alternative in writing; keep EIR and queue records |
| Forwarder is the contracting party | Cargo owner may face a back-to-back claim | Double exposure for charges and fees | Medium | Agree charge pass-through limits in the forwarding contract |
| Customs hold extends free time use | Usually not a ground for free relief unless the tariff says so | Charges accrue while cargo is lawfully held | High | Pre-clear documents; negotiate extended free time for inspection risk |
| Missed contractual dispute deadline | Possible loss of right to contest | Charge becomes payable by default | High | Diary the deadline; send a holding reply immediately |
Hypothetical scenario
Hypothetical scenario. Assume a Vietnamese importer buys machinery on FOB terms and the carrier’s bill of lading incorporates its published tariff. Assume five days of combined free time starting at discharge, a customs documentary inspection that holds the container for four days, and a delivery order released by the carrier one day late because freight was paid late by the importer’s forwarder. Assume the carrier invoices ten days of demurrage and detention at escalating rates and threatens to hold the next shipment.
The importer’s analysis would proceed in three steps. First, separate the periods: the day lost to the carrier’s late release may be a ground for a reduction, while the customs hold probably is not, unless the tariff provides relief. Second, check whether the forwarder, as booking party, is the primary debtor and whether the forwarding contract allows pass-through. Third, assemble timestamps and correspondence, pay the undisputed portion, and propose a without-prejudice settlement. The assumptions are illustrative only; real outcomes depend on the actual contract terms and evidence.
Claims against carriers and terminals in container demurrage and detention Vietnam disputes
Where the cargo owner suffers loss because of the carrier’s or terminal’s own default, such as wrongful refusal of an empty, loss of the container interchange record, or delay in release, it may be able to set off or counterclaim. Claims against terminals may rest on a separate terminal contract or on tort principles, and the limitation rules differ from those for carriage claims.

Frequently Asked Questions
Is demurrage the same as detention?
No. In common market usage, demurrage applies to a container kept inside the terminal beyond free time, while detention applies to a container kept outside the terminal. Some carriers merge them, so always read the tariff.
Can a carrier hold my cargo for unpaid charges?
It depends on the bill of lading terms and applicable law. Many carriers assert a contractual right to withhold release. Verify the clause, and consider payment under protest or security to avoid compounding delay.
Do weekends and Tet holidays count as free time days?
That depends on the tariff. Some count calendar days, others exclude weekends or holidays. Do not assume relief; check the wording and request written confirmation before shipment.
What evidence best supports a dispute?
The tariff version in force, release and gate timestamps, the equipment interchange receipt, customs hold records and written requests for alternative return, together with the invoice calculation.
Who pays if my forwarder booked the cargo?
The carrier may invoice the forwarder as contracting party, and the forwarder may pass the charge on under its own conditions. Agree pass-through terms and limits in the forwarding contract.
Conclusion and next action
Container demurrage and detention Vietnam charges are contractual, time-driven and evidence-dependent. For container demurrage and detention Vietnam exposure, the best protection is preventive: fix free time and start and stop events before booking, diarise deadlines, document every delay, and respond to invoices in writing within the stated period. Dispute strategy should combine legal analysis with commercial leverage, because the next shipment is usually what is at stake.
Next action: within the next five working days, list your open containers, identify the booking party and tariff for each, and send the contracts and invoices for any container already over free time to your counsel for a confidential review.
