Cabotage Vietnam Foreign Vessels: Structures, Licences and Risk

Updated: 14 October 2026 · IVLF Advisors

A foreign-flag ship that lifts cargo between two Vietnamese ports without the right authority can leave the owner, the charterer, the lender and the cargo interests with the same problem: a voyage that was commercially sensible but legally exposed. The issue of cabotage Vietnam foreign vessels is rarely noticed at fixture stage, because the charter party looks ordinary and the freight is attractive. It surfaces later, when a port authority asks about the vessel’s right to trade, when an insurer reads the trading warranties, or when a bank tests its security.

This article explains where the line usually falls between permitted and restricted domestic carriage, which structures commercial parties use to stay on the right side of it, and what a disciplined compliance file looks like. It is written for shipowners, charterers, cargo owners and financiers who need a decision framework, not a statute digest. Where current licensing detail is not verified, we say so and flag it for confirmation.

Why cabotage Vietnam foreign vessels is a structuring question

Cabotage is the reservation of domestic carriage to national tonnage. States use it to protect national fleets, crews and strategic trades, and most maritime nations apply some form of it. The commercial lesson is that cabotage is not a single rule but a family of rules, each with its own exceptions, licences and enforcement habits.

For Vietnam, the starting point is the Maritime Code 2015 (Law 95/2015/QH13, effective 1 July 2017, now available in the consolidated text 101/VBHN-VPQH of 26 August 2025). The code sets the framework for sea transport and for who may carry cargo between Vietnamese ports. The detailed conditions sit in implementing decrees and in practice at the maritime administration. The practical risk is that parties assume a foreign-flag ship may trade domestically if the cargo owner consents. Consent of the cargo owner is not the test.

Why cabotage Vietnam foreign vessels is easy to miss

Three features of a typical fixture hide the problem. First, the charter party is often a standard form that says nothing on trading rights. Second, the broker chain is focused on rate and laycan, not on flag-state or port-state permissions. Third, a short domestic leg is added to an international voyage as a convenience.

Each is a point where a compliance question should be asked.

Who carries the risk

• Owner: detention, delay, fines and a damaged trading record with the port authority.
• Charterer: loss of the voyage, cargo delay and claims from receivers.
• Lender and insurer: impaired earnings and arguments over trading limits.

The legal baseline and what counts as domestic carriage

At principle level, domestic carriage means carriage of cargo or passengers from one port or place in Vietnam to another port or place in Vietnam. For cabotage Vietnam foreign vessels analysis, the question is how the rules treat a leg that is part of an international voyage, a transhipment, or a call for part discharge. The answer depends on the text of the current decrees and on administrative practice. Do not rely on a trading assumption from another jurisdiction.

The verified instruments that frame the analysis are these:

• The Maritime Code 2015 (Law 95/2015/QH13) and its consolidated text 101/VBHN-VPQH.
• Decree 160/2016/NĐ-CP on conditions for shipping business, ship agency and towage services, with a consolidated text published by the Vietnam Maritime and Waterway Administration on 30 September 2026. Amendments include Decree 14/2026/NĐ-CP.
• Decree 171/2016/NĐ-CP on registration of seagoing vessels, amended by Decree 247/2025/NĐ-CP effective 30 October 2025.
• Decree 58/2017/NĐ-CP on maritime activity management, as amended, including by Decree 14/2026/NĐ-CP.

A draft Maritime and Inland Waterway Code is under preparation by the Ministry of Construction. It is a draft only, it is not adopted, and its content may change. Do not price long-term employment on a draft position.

Questions that decide whether a leg is restricted

Before accepting a domestic or part-domestic employment, ask a fixed set of questions and record the answers:

• Do loading and discharge points both lie in Vietnam, including offshore terminals?
• Is the cargo moving under one contract of carriage that begins and ends in Vietnam?
• Is there a transhipment or feeder element that changes the characterisation?
• Is the vessel flagged in Vietnam, or foreign-flag under a bareboat charter registration?
• Does an exception for non-availability of suitable Vietnamese tonnage apply, and who grants it?

If any answer is uncertain, the safe course is to treat the leg as restricted until the authority confirms otherwise in writing.

Structuring options for domestic cargo transport by sea

Commercial parties generally choose between four routes to manage cabotage Vietnam foreign vessels exposure. They differ in cost, speed and enforcement risk, and none should be adopted without checking the current decrees. The central structural tool for foreign owners is a bareboat charter to Vietnamese company, which can place the vessel under Vietnamese registration for the charter period.

Option 1: Vietnamese-flag tonnage on a time or voyage charter

The least contentious route. The owner is a Vietnamese operator, the vessel is on the Vietnamese register, and the usual shipping business conditions apply to the operator. The limit is availability and price: suitable tonnage may not exist for a given cargo, size or timing.

Option 2: bareboat charter to Vietnamese company

A foreign owner demise-charters the vessel to a Vietnamese company, which then operates it under Vietnamese registration for the charter period. This can open domestic trades to an asset that is otherwise foreign. It also moves operational responsibility, crewing and insurance obligations to the Vietnamese bareboat charterer, and it requires careful alignment of the head-owner’s mortgage and flag consents. Decree 171/2016/NĐ-CP, as amended by Decree 247/2025/NĐ-CP, governs registration forms, but the conditions for bareboat registration of foreign vessels must be checked at the time.

Option 3: a one-off exemption or permission

Some systems allow a specific voyage by foreign tonnage if no suitable national vessel is available. Whether, how and by whom such permission is given in Vietnam today, and what evidence of unavailability is expected, are matters to confirm with the maritime administration before relying on it.

Option 4: restructure the voyage

Sometimes the commercial purpose is met by a genuine international voyage with a different sequence of ports. This must be real. A paper restructuring that disguises a domestic movement is the highest-risk option, because it combines cabotage exposure with misdeclaration.

Option	Legal position	Commercial impact	Risk	Mitigation
Vietnamese-flag ship, time or voyage charter	Within the general domestic regime	Limited tonnage choice; predictable compliance	Low	Verify the operator’s shipping business conditions and vessel certificates
Bareboat charter to Vietnamese company	Depends on registration conditions for foreign-owned hulls	Opens domestic trades; shifts operation to charterer	Medium	Conditions precedent on registration, owner and mortgagee consents, insurance alignment
Specific permission for foreign tonnage	Exception, if available; scope and process to be confirmed	Timing uncertainty; may be per voyage	High	Written permission before fixing; cancellation right if refused
Voyage restructured to appear international	Substance over form	Cheap on paper, costly if challenged	Fatal	Do not adopt unless the international voyage is real and documented

Coastal trade licence and the Vietnamese flag requirement

Two concepts overlap in any cabotage Vietnam foreign vessels review and are often confused. The first is the right of the vessel to carry domestic cargo, which is tied to flag and registration. The second is the right of the operator to run a shipping business, which is tied to licensing and conditions under Decree 160/2016/NĐ-CP. A vessel can satisfy one and fail the other.

The Vietnamese flag requirement in practice

The Vietnamese flag requirement is the usual gateway to domestic carriage. In practice a vessel needs a valid certificate of registration, class and statutory certificates, and an owner or bareboat charterer who is entitled to hold the registration. Decree 247/2025/NĐ-CP introduced and clarified registration without time limit and ship-age rules, so the age and registration category of the vessel should be tested early. The specific age limits for specific ship types are not set out here because they must be confirmed from the current text.

Where a coastal trade licence enters the picture

Where a transaction depends on a coastal trade licence or an equivalent permission, treat it as a condition precedent, not a post-fixture task. Ask four things: who is the issuing authority, what documents are needed, how long the process takes, and whether the permission is vessel-specific, voyage-specific or time-limited. Do not describe a licence as obtained until the written document is in the file.

Charter party drafting points

• A trading-rights warranty from the party that controls flag and licence status.
• A condition precedent that permission and registration are in place before laydays start.
• A right to cancel and recover costs if a permission is refused or revoked.
• An indemnity for fines and delay caused by a breach of domestic trading rules.

Hypothetical scenario: a coastal coal and clinker trade

Hypothetical scenario. The facts below are assumed for illustration only and do not describe any real transaction.

• A foreign owner holds a geared bulk carrier on a foreign register, financed by a bank with a first mortgage.
• A Vietnamese cement producer wants to move clinker from a northern port to a southern port under a long-term contract of affreightment.
• The broker proposes a voyage charter on a standard form, with no trading-rights clause.

The producer’s logistics team assumes the foreign flag is acceptable because the owner is reputable. The owner assumes the producer will deal with any permissions, because it is the local party. Neither has asked whether the carriage is a restricted domestic movement.

What a careful adviser would do

1. Characterise the movement: it begins and ends in Vietnam, so treat it as domestic carriage.
2. Test Option 1 first: is suitable Vietnamese-flag tonnage available at an acceptable rate?
3. If not, test Option 2: can a Vietnamese company bareboat charter the vessel, and will the mortgagee consent to the change of operator and flag arrangement?
4. Confirm in writing with the authority which route is acceptable.
5. Make the permission and registration conditions precedent in the charter, with a cancellation right.
6. Align the hull and P&I cover with the new trading pattern and operator.

The parties either find Vietnamese tonnage or re-paper the deal as a bareboat structure, with a longer timetable but a defensible file.

Enforcement exposure, financing and a compliance checklist

Enforcement tends to arrive through the port, not through a court. A port authority, a harbour master or a customs officer asks for documents. If the vessel’s trading right cannot be shown, the immediate consequence is delay. The later consequences may include administrative penalties and records that follow the vessel and the operator. Specific penalty levels are not stated here because they must be checked in the current penalty decrees.

How cabotage restrictions affect financing and insurance

Lenders care because cabotage restrictions limit employment options and can freeze earnings. Insurers care because a vessel trading outside permitted limits can create coverage disputes. At the level of market practice under English-law policies, a breach of a trading warranty can give the insurer a defence, and the exact consequence depends on the policy wording and governing law. That is English-law and market practice, not a statement about Vietnamese law.

Compliance checklist before accepting a domestic leg

• Map every port and terminal on the voyage and mark which are in Vietnam.
• Record flag, registration category, class and statutory certificates.
• Check the owner’s or bareboat charterer’s shipping business conditions under Decree 160/2016/NĐ-CP.
• Obtain the authority’s written position on trading rights where there is doubt.
• Insert trading-rights warranties, conditions precedent and cancellation rights in the charter.
• Notify the mortgagee, the hull underwriter and the P&I club before the voyage.
• Retain voyage documents and authority correspondence for the audit file.

Frequently Asked Questions

Is cabotage Vietnam foreign vessels a bar on all foreign ships?

Not absolutely, but it is the default. Domestic carriage is generally reserved to Vietnamese-flag tonnage, subject to exceptions whose scope and process must be confirmed with the maritime administration before the voyage.

Does a bareboat charter to a Vietnamese company solve the problem?

It can, if the vessel is registered under the Vietnamese flag for the charter period and all conditions are met. It also needs mortgagee consent and insurance changes, so it is a structure, not a shortcut.

Is cargo owner consent enough to allow a foreign ship to trade domestically?

No. Consent between private parties does not replace the authority’s permission or the vessel’s registration status. Obtain written confirmation from the authority where there is doubt.

Who bears the loss if a domestic voyage is stopped?

The answer depends on the charter party. Without a trading-rights warranty and cancellation clause, the allocation is uncertain and usually disputed. Draft the allocation before fixing.

Will the draft Maritime and Inland Waterway Code change these rules?

It may, but it is a draft, it is not adopted and its content may change. Plan on current law and review any enacted text when it is published.

Conclusion and next step

The lesson of cabotage Vietnam foreign vessels is that foreign tonnage can serve Vietnamese domestic routes only where the vessel’s flag, registration and permissions line up with the voyage. The commercial discipline is simple to state: characterise the voyage first, choose the structure second, and make permission a condition precedent, not an afterthought. A single page recording the voyage map, flag position and written authority position serves every party.

Next action: before the next domestic or part-domestic fixture, build the one-page trading-rights file described above and have it checked against the current decrees.
