Vous venez de dépenser 30 000 € pour un moule de production dans une usine chinoise. Six mois plus tard, vous souhaitez déplacer la production ailleurs — et l'usine déclare que le moule leur appartient. Non, ils ne l'expédieront pas. Oui, ils sont prêts à continuer à fabriquer vos pièces. À leurs conditions. Ça vous dit quelque chose ? Cela arrive plus souvent qu'on ne veut l'admettre, et la différence entre récupérer votre moule et le perdre complètement dépend d'un seul document : l'accord de propriété du moule.
- Les fournisseurs chinois revendiquent souvent la propriété du moule par défaut — un accord écrit est essentiel
- Les accords NNN protègent votre propriété intellectuelle mais n'établissent pas la propriété du moule
- Les contrats de propriété de moule doivent être exécutoires en vertu du droit chinois, en chinois
- Inclure des clauses claires de transfert, stockage, assurance et résiliation
- La due diligence sur votre fournisseur compte autant que le contrat lui-même
Qu'est-ce qu'un contrat de propriété de moule par injection ?
Un accord de propriété de moule d'injection est un document juridique prouvant que vous — et non l'usine — possédez votre Mold Tooling1. En Chine, ce document n'est pas facultatif : sans lui, l'hypothèse par défaut dans de nombreuses usines est qu'elles possèdent l'outillage qu'elles ont fabriqué sur leurs locaux. L'accord couvre généralement la PI de conception du moule, les droits de transfert, les conditions de stockage, les obligations d'assurance, les responsabilités de maintenance et ce qui se passe si le fournisseur fait faillite.
L'accord couvre généralement la propriété intellectuelle de la conception du moule, les droits de transfert, les conditions de stockage, les obligations d'assurance, les responsabilités de maintenance, et ce qui se passe si le fournisseur fait faillite. Considérez-le comme l'acte de propriété d'un actif à six chiffres se trouvant dans le bâtiment de quelqu'un d'autre — sauf que le bâtiment est à 13 000 km, et le système juridique local fonctionne différemment de ce à quoi vous pourriez vous attendre.
Pourquoi les usines chinoises résistent-elles au transfert de propriété des moules ?
La raison pour laquelle les usines chinoises résistent au transfert de propriété des moules est simple : conserver votre outillage verrouille des revenus de production récurrents. La plupart des Chinois moulage par injection Les fournisseurs opèrent sur des marges minces grâce à la production de masse, pas grâce à l'outillage. Leur modèle économique dépend du maintien de la production de vos pièces en interne. Certaines usines proposent l'outillage à prix coûtant ou en dessous spécifiquement pour s'assurer des volumes de production futurs — une stratégie courante parmi toutes. fournisseur de moulage par injection en Chine.
Ce n'est pas intrinsèquement malhonnête — c'est une stratégie de tarification courante dans la fabrication chinoise. L'usine investit dans la construction de votre moule à un prix compétitif car elle s'attend à récupérer cet investissement via la production de pièces sur 12 à 36 mois. Lorsque vous retirez le moule après trois séries de production, ils perdent réellement de l'argent sur cet outillage.
Chez ZetarMold, nous disposons d'une usine de fabrication de moules interne à Shanghai qui produit plus de 100 ensembles de moules par mois. Avec plus de 20 ans d'expérience dans la construction et le transfert de moules pour des acheteurs internationaux, nous avons été témoins de conflits de propriété — et notre pratique standard est d'inclure des conditions de transfert de propriété claires dans chaque accord d'outillage dès le premier jour.
L'implication pratique est que vous devez aborder les attentes en matière de propriété dès le départ, avant tout échange d'argent. Les usines qui résistent à cette conversation sont souvent les mêmes qui résisteront à la libération de votre moule plus tard. Dans notre expérience chez ZetarMold, la transparence sur les conditions de propriété dès le premier jour renforce en fait la relation commerciale — les deux parties savent exactement où elles en sont.
Dans notre expérience avec les clients internationaux chez ZetarMold, nous avons vu des projets où le fournisseur précédent refusait de libérer des moules d'une valeur de plus de 50 000 € simplement parce qu'il n'y avait pas d'accord écrit de propriété. L'acheteur avait payé intégralement. Le fournisseur s'en moquait — il avait la possession physique, et sans un contrat sous loi chinoise, l'acheteur n'avait pratiquement aucun levier.
Quelles clauses clés un accord de propriété du moule doit-il inclure ?
Un accord de propriété du moule exécutable est celui qui couvre six clauses essentielles. Ce sont : (1) une déclaration de propriété claire, (2) les droits de transfert et de récupération, (3) les obligations de stockage et de maintenance, (4) les exigences d'assurance, (5) une interdiction d'utilisation non autorisée, et (6) les conditions de résiliation et de règlement des litiges. L'absence de l'une de ces clauses crée une faille qu'un fournisseur peut exploiter.
| Clause | What It Covers | Why It Matters |
|---|---|---|
| Déclaration de Propriété | Déclaration explicite que l'acheteur possède le moule et toute la PI | Établit le titre légal — empêche les réclamations par défaut du fournisseur |
| Droits de Transfert | Conditions et délai pour la récupération du moule | Sans cela, le fournisseur peut retarder indéfiniment |
| Stockage & Maintenance | Comment le moule est stocké, qui paie pour l'entretien | Empêche la dégradation et les frais de réparation imprévus |
| Assurance | Qui assure le moule et pour quel montant | Protège contre la perte, les dommages ou la faillite de l'usine |
| Interdiction de Non-Utilisation | Le fournisseur ne peut pas utiliser le moule pour d'autres clients | Empêche la copie ou la production non autorisée |
| Conditions de Résiliation | Ce qui se passe lorsque la relation prend fin | Définit le processus de sortie et le délai de récupération |
« Un accord de propriété du moule doit préciser le calendrier exact de récupération du moule. »Vrai
Inclure un délai de récupération spécifique (généralement 30 jours après demande écrite) avec des pénalités pour retard vous donne des échéances exécutoires plutôt que des obligations vagues.
« Un NDA standard signé en anglais suffit à établir la propriété du moule en Chine. »Faux
Un accord de confidentialité uniquement en anglais n'établit pas la propriété du moule selon la loi chinoise. Vous avez besoin d'un accord séparé de propriété du moule en chinois, régi par la loi chinoise, avec des dispositions claires de transfert de titre.
Comment la loi chinoise traite-t-elle la propriété des moules ?
Under Chinese law, mold ownership is determined by what the written contract states — in Chinese, under Chinese law, via Chinese arbitration. Foreign-court judgments are generally not enforceable in China. Under the PRC Civil Code (effective January 2021), mold ownership follows the contract between the parties. If the contract says you own it, you own it — in theory. In practice, enforcement requires specific contract provisions.
This means a mold ownership agreement drafted in English under New York law is essentially worthless if the factory is in Shenzhen and decides to keep your mold. You need a bilingual agreement — with the Chinese text controlling in case of discrepancy — filed with a recognized Chinese arbitration institution. It costs more upfront, but it is the only version a Chinese factory will actually respect.
Quelle est la différence entre un accord NNN et un accord de propriété du moule ?
Un NNN Agreement2 and a mold ownership agreement are two separate documents protecting different things — your IP versus your physical tooling. An NNN agreement (Non-Disclosure, Non-Use, Non-Circumvention) protects your intellectual property — designs, drawings, specifications. A mold ownership agreement protects your physical asset — the steel moule d'injection tooling itself. They serve different purposes, and you need both.
We have seen buyers who had a solid NNN in place but lost their molds because they never signed a separate ownership agreement. The NNN prevented the supplier from copying the design — theoretically — but it said nothing about who owned the physical mold. The factory argued (successfully) that without a specific ownership clause, the mold was theirs under local commercial custom. Two different documents, two different protections. Do not skip either.
The lesson is straightforward: never assume that one document covers everything. IP protection and physical asset protection are parallel but distinct legal needs, and Chinese courts treat them as separate matters requiring separate contractual foundations.
The scope of protection differs fundamentally. An NNN prevents the factory from sharing your CAD files or making your product without permission — it addresses information security. A mold ownership agreement addresses property rights: who holds title, who controls access, and what happens to the physical steel when the relationship ends. In Chinese legal practice, these are separate legal concepts covered by separate areas of law.
“Engraving your company name on the mold helps prove ownership in disputes.”Vrai
Physical marking of the mold with buyer identification supports the Bailment3 claim and makes it harder for the factory to argue the mold is part of their assets.
“Chinese courts will enforce foreign court judgments on mold ownership disputes.”Faux
China generally does not enforce foreign court judgments. Your mold ownership agreement must specify Chinese arbitration (e.g., CIETAC) for enforceable dispute resolution.
Quand devez-vous négocier les conditions de propriété du moule ?
The best time to negotiate mold ownership terms is before you place the tooling order — not during production, and certainly not after. The supplier wants your business most during the quotation and vendor selection phase. Once you have paid the deposit and they are cutting steel, your leverage drops significantly.
Include ownership terms in your initial RFQ or purchasing agreement. Make it clear from the first interaction that mold ownership is a deal-breaker. Suppliers who refuse to sign an ownership agreement before taking your tooling order are telling you something important about how the relationship will go.
In practical terms, here is the negotiation sequence we recommend: (1) Sign the NNN first, before sharing any design files. (2) Include mold ownership terms in the manufacturing agreement or as a standalone addendum. (3) Pay for tooling only after both documents are executed. (4) Insist on receiving mold design files (CAD data) as part of the delivery. This four-step approach protects both your IP and your physical tooling investment.
“A mold ownership agreement should name who is authorized to collect the mold on the buyer’s behalf.”Vrai
Specifying an authorized representative or third-party agent in the agreement prevents disputes over who has the right to physically take possession of the mold during retrieval.
“Once you sign a mold ownership agreement, you do not need an NNN agreement.”Faux
These serve different purposes. The ownership agreement covers the physical mold; the NNN protects your design IP. You need both for complete protection.
Que devient votre moule si le fournisseur chinois fait faillite ?
Your mold is treated as factory assets in a Chinese bankruptcy — unless your agreement explicitly carves it out. This is a clause most buyers never think about, and it is one of the most important. Without a specific bankruptcy carve-out, you become just another unsecured creditor waiting in line.
The solution is a contractual clause stating that the mold is buyer property held in bailment (a bailment relationship under Chinese law), not a factory asset. Combined with an equipment tag or engraving showing buyer name and asset number, this creates a stronger claim that the mold is not part of the factory’s bankruptcy estate. It is not foolproof — Chinese bankruptcy proceedings can be unpredictable — but it gives you a legal argument that pure possession-based claims lack.
We recommend including a specific provision that the mold is excluded from any creditor claims, pledge, or lien by the factory or its affiliates. Additionally, require the factory to maintain separate storage for customer-owned molds — physically distinct from their own tooling inventory. These structural separations, combined with proper documentation, significantly improve your position in any insolvency scenario.
Comment récupérer physiquement un moule d'une usine chinoise ?
Mold retrieval is a formal process. You invoke your ownership agreement, send a 30-day transfer request, and arrange shipping. If the factory refuses, arbitration under Chinese law is your recourse. The practical steps are: (1) Send a formal written request citing the ownership agreement, with a reasonable deadline (typically 30 days). (2) Arrange and pay for shipping, insurance, and any outstanding maintenance costs. (3) Have a third-party inspector verify mold condition before it leaves the factory. (4) If the factory refuses, initiate arbitration under the contract’s dispute resolution clause.
At our Shanghai factory, ZetarMold operates 47 injection molding machines ranging from 90T to 1850T. When a client needs to retrieve a mold and move production to our facility, we can usually qualify the tool and start sampling within two weeks — because the equipment range covers virtually any mold specification.
The retrieval process itself can take 2–6 weeks under normal circumstances. If there is resistance, arbitration in China can take 6–12 months. This is why the agreement must specify a clear transfer timeline and penalties for non-compliance. A clause stating the factory must release the mold within 30 days of written request, with a daily penalty for delay, gives you measurable recourse.
Some buyers opt to have an injection molding sourcing agent or third-party logistics provider handle the retrieval. This can reduce friction, as the factory may be more willing to release the mold to a neutral party rather than a competitor. Either way, make sure your ownership agreement names who is authorized to collect the mold on your behalf.
Quelles sont les questions les plus fréquentes sur la propriété des moules en Chine ?
Can a Chinese factory legally keep my mold if there is no written agreement?
Yes. Without a written ownership agreement governed by Chinese law, the factory can claim ownership based on possession and manufacturing custom. Verbal agreements are extremely difficult to enforce in China, and email confirmations alone carry limited legal weight in Chinese courts. The default legal position in many Chinese jurisdictions favors the party with physical possession of the tooling asset, which is almost always the factory that built and housed the mold on their premises. This is precisely why a formal bilingual contract is not optional — it is the only reliable protection for your tooling investment.
How much does a mold ownership agreement cost to draft?
A qualified China-focused manufacturing lawyer typically charges $2,000–$5,000 for a comprehensive mold ownership agreement with NNN provisions included. This represents a fraction of the mold’s replacement value — most production molds for injection molding cost between $10,000 and $80,000 depending on cavity count, steel grade, and geometric complexity. Think of the agreement cost as an insurance premium protecting a high-value manufacturing asset that sits in a factory thousands of miles away, under a legal system you may not be familiar with.
Should the mold ownership agreement be in Chinese or English?
Both languages, with the Chinese text explicitly designated as the governing and controlling version in the agreement itself. Chinese courts and arbitration bodies rely exclusively on the Chinese text as the authoritative legal document for any dispute resolution process. Any discrepancy between the English and Chinese versions will be resolved using the Chinese text, which means both versions must be drafted carefully and consistently by qualified legal counsel who specialize in cross-border manufacturing contracts and bilingual commercial agreement preparation and enforcement.
What if my supplier refuses to sign a mold ownership agreement?
Find a different supplier immediately — this is a deal-breaker. A factory that will not agree to basic ownership terms is clearly signaling that they intend to retain your tooling as leverage for continued business. This is a non-negotiable red flag in any injection molding partnership, regardless of how competitive their part pricing appears to be. The long-term risk of losing access to a mold worth tens of thousands of dollars far outweighs any short-term cost savings that factory might offer on individual part prices.
Can I get mold insurance to protect my investment in China?
Yes, tooling insurance is available through trade credit insurers and specialized manufacturing insurance providers who understand the China market. These policies can cover mold loss, physical damage, or supplier default scenarios. Your ownership agreement should require the factory to carry comprehensive insurance naming you as the loss payee, with coverage equal to the full replacement cost of the mold tooling. This provides a financial backstop that operates completely independent of the factory’s financial health or their willingness to cooperate with your mold retrieval requests at any point.
Does paying for the mold in full automatically make me the owner in China?
No, payment alone does not establish ownership under Chinese commercial practice or contract law. A written agreement stating ownership title — separate from the payment record, purchase order, or commercial invoice — is necessary to prove legal title in any dispute. The factory’s invoice confirms you paid for tooling services, but it does not establish that you own the resulting physical mold asset. Only a dedicated ownership agreement with proper legal structure creates that enforceable claim under the PRC Civil Code.
How long does mold retrieval arbitration take in China?
CIETAC arbitration typically takes 6–12 months for mold ownership disputes from initial filing through to the final arbitral award being issued. Local arbitration commissions in major manufacturing cities like Shenzhen, Dongguan, or Shanghai may resolve cases faster, sometimes within 3–6 months, but enforcement speed varies significantly by jurisdiction and local court cooperation levels. Always include a specific arbitration clause naming the institution, the city, and the governing language in your ownership agreement to minimize procedural delays and jurisdictional disputes during the arbitration process.
What should I do if a supplier uses my mold for another client?
Send a formal written cease-and-desist letter immediately, citing both your NNN agreement and mold ownership agreement as the legal basis for your demand. Document the unauthorized use thoroughly with photographs of the copied parts, physical samples purchased through third parties, and shipping records before taking any formal legal action. If the supplier continues unauthorized production after receiving your notice, initiate arbitration proceedings promptly under your contract’s dispute resolution clause. Acting quickly and documenting everything comprehensively strengthens your legal position significantly.
Quick rule: before you pay for tooling in China, have two documents ready — an NNN for your IP, and a mold ownership agreement (in Chinese, under Chinese law) for the physical mold. If the factory will not sign both, walk away. No discount is worth losing a costly mold. At ZetarMold, we provide transparent mold ownership agreements as standard practice — your tooling is your asset, not a negotiating chip.
