You paid the tooling fee. The mold sits in the supplier's plant. Without the right clauses, switching suppliers means discovering that the most valuable asset in your supply chain legally belongs to — or is held by — someone else.
Every importer of custom parts knows the arrangement, even without reading it in a contract: the buyer pays a tooling fee, the supplier builds the mold, the mold lives in the supplier's factory. The cavities that define your product — the geometry you specified, the steel you paid for, the modifications you approved at first article inspection — sit on a machine floor in Dongguan or Ningbo, in the hands of the company you may one day need to leave.
I review a steady stream of China purchase contracts, and the tooling clause is among the most consistently mishandled provisions I see. Not absent, exactly — often a line saying the buyer pays a "mold fee." What is missing is everything that makes ownership mean something: who holds title, who can take the tool away, who must help when you do, and what happens to the money if nobody ships another part.
This article covers what goes wrong, what Chinese law gives you by default, and the clause set that fixes it.
The standard commercial story is comfortable. You develop a custom part — an ODM housing, a private-label component, a plastic assembly with your geometry — and the supplier quotes a tooling charge on top of the piece price. You wire the tooling fee with the deposit; the supplier commissions the mold, runs T1 samples, and after first article inspection mass production begins. For two or three years, nobody thinks about the mold at all.
Then the relationship sours. Corrective action requests go unanswered, lead times stretch, or the supplier raises the piece price and dares you to move. You decide to second-source — and only then does someone ask the operational question: where is the mold, and can we take it?
If your contract does not answer that question in writing, the answer is decided by leverage, not law — and at that moment leverage belongs to whoever holds the steel. The suppliers in these situations are rarely villains; the tooling fee often did not cover the real mold cost, and the piece price was set assuming they would recoup the difference over the production run. When you leave early, they see a subsidized tool and a customer walking. Without a written tooling clause, their grievance becomes your problem.
In disputes I have handled or reviewed, the loss takes three shapes, in rough order of frequency.
First: the mold is simply held. You serve a tooling release request; the supplier stops responding, or responds with conditions — settle the open invoice first, commit to a minimum order quantity, sign a new price agreement. Suppliers sometimes dress this up as a "lien" over the tool for unpaid amounts; whether any such right exists depends on what was agreed, which in most cases was nothing. The delay alone does the damage — replacement tooling lead time is measured in months, and the supplier knows it.
Second: the mold is "bought back" at a discount. A softer version: the supplier agrees to release the tool, but only after deducting "amortization" — a figure claiming the tool was being written off over a projected volume, of which only part was produced. Presented as settled accounting; in reality a negotiation conducted in the language of bookkeeping. I have seen buyers pay substantial sums to retrieve tools they had fully paid for, because the contract was silent and the shipping schedule would not wait.
Third: the mold keeps running for other people. The quietest and most corrosive loss. The tool you paid for continues to produce your geometry — for another customer, sometimes under another brand. If your contract does not prohibit third-party production with your tooling, and your IP protection is thin (a design patent not filed in China, no copyright registrations, no confidentiality architecture worth the name), your remedy is weak and slow. The first two losses cost money. This one costs the product itself.
The good news is that Chinese law gives you a clean framework — if you use it. Ownership of the mold is a matter of contract. If the contract says the buyer owns the tooling upon payment of the tooling fee, then under Chinese law the buyer owns it, and the supplier holds it as a bailee. The disputes above are, at bottom, disputes about a bailment without terms.
Two provisions of the Civil Code of the PRC (中华人民共和国民法典) are worth knowing here, because they frame how Chinese courts think about ownership and possession in sales of goods.
Article 641 provides that the parties may agree that the seller retains ownership of the goods until the buyer pays or performs another obligation — the retention-of-title mechanism — and adds a critical detail: a retained ownership that has not been registered may not be asserted against a bona fide third party. The provision protects sellers who finance their buyers. Read from the buyer's side, the lesson is the one that runs through this whole article: ownership that lives only in the parties' private understanding is vulnerable to everyone else in the chain — a supplier's creditor freezing plant assets, an upstream mold maker never paid for the steel, a lender with a registered security interest over the factory's equipment.
Article 642 gives a seller who has retained ownership a statutory right of repossession where the buyer fails to pay after demand and a reasonable period, or otherwise frustrates the seller's security interest — the right to take the goods back. Buyers are usually surprised that Chinese law contains a built-in "come and take it" mechanism at all. The takeaway for a buyer who owns tooling is to mirror the logic contractually: where ownership and possession are separated — your mold, their factory — the contract should contain your own express retrieval right, not an argument by analogy from an article written for the other side.
A third-party point that decides real cases: if the supplier's creditor applies to freeze or execute assets at the plant, a court will ask who owns the mold. Your ownership clause is your evidence. If the tool was never tagged, never entered in a tooling register, never invoiced as buyer-owned property held in bailment, your paper fights the presumption that everything on that factory floor belongs to the company on the business license.
A tooling clause that functions is not one sentence. It is a short set of provisions, each answering a different failure mode.
| Provision | What it must say | Failure mode it prevents |
|---|---|---|
| Ownership | Title vests in the buyer on payment of the tooling fee (or pro rata if staged); the supplier holds it as bailee, at its risk | The "everything here is ours" presumption, and the supplier's creditor seizing your tool as the supplier's asset |
| Identification | Tooling marked with buyer's name and tool number; schedule annexed (tool ID, cavities, shots, location); register available for audit | "Which machine is yours?" arguments; tools commingled with the supplier's own |
| Retrieval & relocation | On written request, release within a fixed number of days, packed to agreed standards, with assistance in dismantling, crating and onward shipping — at the buyer's cost, but cooperation obligations that are unconditional | The hostage scenario; the "release fee"; cooperation that evaporates when you need a truck |
| Exclusivity of use | The tooling may be used solely to manufacture products for the buyer; no third-party production or relocation without written consent | Your geometry running for other customers; the tool quietly moved to a subsidiary |
| Maintenance & access | Scheduled preventive maintenance at the supplier's cost (or as agreed), tool-life tracking in shots, buyer's right to inspect the tool on notice | Discovering at transfer that the "paid-for" mold is worn out |
Two drafting details matter more than they look. First, staged tooling payments need staged ownership language — if you pay half the tooling fee and the contract says title passes "upon payment," you may own half a mold. Say so expressly: title passes pro rata, or on final payment with an interim security arrangement. Second, address the supplier's investment honestly. If the tooling fee underfunds the mold and the supplier recovers the balance through the piece price, write the amortization schedule down: a defined recovery per unit, capped, or to a date. A written schedule converts the "buyback discount" negotiation into arithmetic — and gives you the number to audit against.
Treat the tooling file as a document-preservation problem: the accounting trail is what proves ownership and defeats invented amortization claims when it matters.
None of this requires the supplier's cooperation — it is all generated in the ordinary course of buying. Start at the first order, not the breakup.
A useful illustration of method, anonymized: I once ran full contract risk control for a Chinese state-owned trading group's import program — a chain of purchase documents, framework terms, quality agreements and annexes, drafted by the seller. The exercise was not about any single clause; it was about how the documents interlock, and tooling-style questions are exactly the kind that surface only when you read the chain as a whole.
The working questions were always the same three. First: which document actually governs? Purchase orders referencing framework agreements referencing supplier terms — with the supplier's general conditions appended to a proforma invoice nobody countersigned. A battle-of-the-forms problem: two sets of paper silently overriding each other, with the tooling clause — or its absence — hiding in the least-read document of the set. Second: does the annex carry the asset? Schedules — tooling lists, specification sheets, drawings — are where ownership language belongs, and they are also the pages most often "to follow" at signature. A contract incorporating annexes that were never finalized has not actually allocated the asset. Third: does the paper match the entity? The company that signs, the company that holds the tool, and the company that invoices are sometimes three different names in one group. Ownership language naming one entity while the mold sits in another's plant is a dispute you have scheduled for the future.
That review produced dozens of annotated issues across the document chain — and the pattern generalizes to any buyer, state-owned or not. The tooling question is never really "who owns the mold." It is "which document, signed by which entity, says so."
Before you sign — or before the next order, on any custom-parts program — run this list:
Suppliers accept these clauses when asked at the start; what they refuse is to grant them after the relationship has broken — which is the only moment most buyers ask. If you want a second pair of eyes on the tooling provisions of a China purchase contract before signature, that is routine work for a contract and trade document review — and it sits naturally alongside the payment-side protections discussed in the payment milestones article, because a tooling fee is a payment milestone tied to an asset.
