Moulds, dies, patterns and fixtures are usually the largest sum a buyer spends before the first production part exists. They are also the asset that sits furthest from the buyer’s control: they live in the factory, they are used every day by the factory’s people, and when the relationship ends they are exactly what the buyer needs to take somewhere else.
Most of what is written in English about tooling ownership comes from the China experience. The principles carry over, but the instruments do not. This article sets out how to structure tooling for a Vietnamese factory — ownership models, getting a mould into Vietnam, the contract clause, what Vietnamese law does to that clause, wear and replacement, and how to recover the tool if you move production.

Why tooling causes more disputes than any other line
Because ownership and physical control separate: you may own the mould, but the factory holds it, uses it and is the party you must ask to release it.
Three features make tooling the usual source of trouble:
- It sits in the factory. Production needs it there, so possession is never yours day to day.
- Payment does not prove ownership. A “mould fee” on an invoice can be read as payment for the work of making the mould, or for the right to have parts made with it, rather than for the mould itself.
- It matters most when the relationship is ending. A request to release tooling usually arrives together with a dispute over price, quality or an unpaid invoice — the worst moment to discover the contract is silent.
Three ownership models, and what each gives you
Tooling is either owned by the buyer and lent to the factory, paid for through the unit price, or owned by the factory; whichever you choose, the party that pays and the party that owns must match on paper.
| Model | How it is paid | Who owns it | Control when you move | Main risk |
|---|---|---|---|---|
| Buyer-owned, lent to the factory | Buyer pays the tooling invoice up front | Buyer, stated in the contract | Strongest — you can demand release | Up-front cash; still needs a release clause |
| Amortised in the unit price | Spread over a stated number of parts | Must be stated; otherwise unclear | Weak unless the contract transfers title at a point | Disagreement over whether amortisation is complete |
| Factory-owned | Factory funds it | Factory | None; you would re-make the tool | Your design can be reused for others unless restricted |
If tooling is amortised, write down the number of parts over which it is amortised, the point at which title passes to you, and the buy-out price if you leave earlier.
Two further steps are worth the effort for expensive tools. First, ask how the factory will invoice the mould — a separate line or invoice naming your company as buyer and the mould by its number is far better evidence than a lump sum inside a parts price. Second, if the factory buys the mould from a separate toolmaker, consider making the toolmaker a party to the agreement, or contracting with it directly, so the design data and title do not stop at the factory.
Getting a mould into Vietnam
A mould you supply from abroad is imported goods in Vietnam, and whether the arrangement is a processing contract or an ordinary purchase decides how it is declared and what must happen to it at the end.
Vietnamese law treats processing — where the ordering party supplies materials and pays for the work — as a distinct commercial arrangement. Article 178 of the Commercial Law 2005 (Law No. 36/2005/QH11) defines it, Article 179 requires the processing contract to be in writing or an equivalent form, and Article 181(2) gives the ordering party the right to receive back leased or lent machinery and equipment, materials and scrap when the contract is liquidated, unless agreed otherwise.
For processing on behalf of a foreign party, the implementing decree under the Law on Foreign Trade Management sets what a processing contract must contain. Under Decree 69/2018/ND-CP this included a list and value of machinery and equipment leased, lent or donated for processing, and the principles for handling leased or borrowed machinery after the contract ends. That decree has been replaced by Decree 292/2026/ND-CP from 5 September 2026, so confirm the corresponding provisions in the current text before you rely on them. In customs practice, machinery leased or lent for a processing contract has been handled under temporary import for re-export, which is why the end of the contract matters: the tool has to be re-exported, transferred to another contract or otherwise dealt with through customs.
The practical points:
- Decide with the factory, before the mould ships, whether it enters as part of a processing contract or under another customs type, and who files the declaration.
- Make sure the commercial invoice and packing list identify the mould by its number, the same number engraved on the tool and used in the contract.
- If you plan to move the mould to another Vietnamese factory later, ask early how that transfer would be handled through customs; it is easier to plan than to improvise.

The tooling clause: what it must say
Because the contract is your main protection, tooling deserves its own clause covering ownership, identification, use, care, wear, release and design data — not a line in the general terms.
| Point | What to write | What it prevents |
|---|---|---|
| Ownership | Each tool, by number, belongs to the buyer; the factory holds it as bailee for the duration of the agreement | ”We only paid for the right to use it” arguments |
| Identification | Engraved or plated tool number and owner’s name; an asset list signed by both sides | Disputes over which tool is which |
| Use restriction | Tool used only for the buyer’s parts; no copies or derivative tools | Your parts appearing under another brand |
| Care and storage | Storage conditions, cleaning, rust prevention, no modification without written approval | Unrecorded changes to the tool |
| Wear and life | Expected life in shots or parts, end-of-life criterion, who pays for refurbishment and replacement | A dispute over whether the tool is “worn out” |
| Insurance and risk | Who insures the tool against fire and damage at the factory | Uninsured loss |
| Release | Release within an agreed time of written request, with the condition the buyer must meet | The tool being held as leverage |
| Design data | Ownership and delivery of tool drawings and 3D data | Having to reverse-engineer your own tool |
| Governing law and disputes | Governing law and arbitration seat agreed in advance | Arguing about where to argue |
The most important lines are ownership and release. A release clause works best when it states the sequence plainly: what the buyer must pay or settle, and then within how many days the factory hands over the tool, its spare inserts and its data.
What Vietnamese law does to that clause
Two features of Vietnamese commercial law shape how a tooling clause should be drafted: penalties are capped, and arbitration awards from outside Vietnam need recognition before enforcement.
- Contractual penalties. Under Article 301 of the Commercial Law 2005, a penalty for breach of a commercial contract may not exceed 8% of the value of the breached part of the obligation, except in the case set out in Article 266. A clause promising a large fixed penalty for misuse of your mould may therefore not be enforceable at that amount. Article 307(2) allows the injured party to claim both the agreed penalty and damages, so record the value of each tool and keep the evidence of what it cost. Watch this point: a draft amendment to the Commercial Law, scheduled for the National Assembly’s session in autumn 2026, proposes to repeal the chapter containing the cap and leave penalties to the Civil Code. Until an amendment is passed and in force, the cap applies.
- Arbitration. Vietnam is a party to the New York Convention, so a foreign arbitral award can be recognised and enforced, but recognition goes through a Vietnamese court. Arbitration in Vietnam is also possible. Choose with that in mind, and take advice from a lawyer qualified in Vietnam for high-value tooling.
Neither point makes the contract less useful. A clear ownership statement, a numbered asset list and a release sequence are what settle most tooling disputes long before anyone files a claim.
Wear, refurbishment and replacement
Tooling wears with every shot, so the expected life, the condition that ends it and the cost split for repair and replacement belong in the contract from the start.
Day-to-day cleaning and minor adjustment are usually the factory’s job; major repair and replacement are where disputes start. Ask for a shot counter or production count per tool and a maintenance log, and review it at intervals — dimensional drift and rising cosmetic rejects in a long-running part are often the first signs of tool wear. Process-specific wear, such as heat checking in die-casting dies, is covered in aluminium die casting from Vietnam; how moulding conditions are recorded is in injection moulding in Vietnam.
Moving production: recovering the tool
The time to plan recovery is before the tool is made; at the point of moving, the plan is simply carried out.
Typical problems when moving production, and what to do about them:
- The tool is held back because of an open invoice or a dispute. Settle accounts in the order the release clause sets, and keep the asset list and ownership evidence at hand.
- The handover drags on. Agree the release procedure and deadline in advance, including who packs, who inspects the tool on handover and who arranges transport.
- There are no drawings. If the factory or its toolmaker designed the tool, insist in the contract on delivery of the tool drawings and 3D data, and keep your own copy from the start. With the data, a lost tool can be remade elsewhere; without it, you start again from a part.
On handover, inspect and photograph the tool, run a sample at the new factory before the old one stops, and keep the old factory’s last approved parts as a reference. Moving production from one country to another raises the same questions on a larger scale; see moving production from China to Vietnam.

Frequently asked questions
1. Is it better to own the tooling outright or amortise it?
Owning it outright gives the most control when you need to move production. Amortising eases cash flow, but only works if the contract states the amortisation quantity, the point at which title passes and the buy-out price if you leave early.
2. Does paying a tooling invoice make me the owner?
Not automatically. The invoice is evidence, but the contract should say in terms that the numbered tool belongs to you and that the factory holds it for you. Without that, the payment can be described as being for the work or for a right of use.
3. Will I pay import duty on a mould I send to Vietnam?
That depends on how it enters — for example as equipment lent for a processing contract under temporary import, or under another customs type — and on the rules in force at the time. Agree the route with the factory and its customs agent before shipping.
4. Can I enforce a large penalty if the factory uses my mould for someone else?
Under the Commercial Law 2005 as it stands, contractual penalties are capped at 8% of the value of the breached obligation, but you can also claim proven damages. A pending amendment may remove the cap, so check the law in force when you sign. Either way, record the value of each tool and keep the evidence.
5. What should I keep in my own files?
The signed asset list with tool numbers, the tooling invoices, photographs of the marked tools, the tool drawings and 3D data, the approved sample from each tool and the maintenance log reports. These are what make a release request quick.
