You Paid for the Mold: Does the Chinese Factory Own It?

You paid a Chinese factory USD 40,000 for molds, the invoice says “tooling fee paid in full,” and the molds stay at the factory while it produces your goods.

Months later, you want to move production — and the factory responds that the molds belong to it, that they cannot leave until you place another order, or that you still owe engineering and material costs.

Payment matters, but it does not answer every question. What the fee purchased, whether title passed, who has custody, what remains unpaid, who owns the drawings and design rights, how the factory may use the tools, and what procedure governs release all have to be established one by one.

Neither side should rely on a slogan. A factory does not automatically own every mold in its building, and a buyer does not automatically acquire every physical and intellectual-property right because it paid a line item called “mold fee.”

First classify what the tooling fee bought

The commercial arrangement may be one of several things:

A sale of completed tooling. The factory or toolmaker builds or supplies a mold for a stated price, and the parties intend ownership to pass to the buyer.

Commissioned manufacture with continued factory custody. The buyer pays for a mold to be created for its production, while the factory keeps physical possession as custodian or user.

Amortized tooling cost. The supplier advances some or all of the tooling cost and recovers it through unit prices or volume; ownership may pass only after a threshold, or may never have been defined at all.

Modification, maintenance, or repair. A payment may cover work on an existing mold rather than purchase of the mold itself.

Shared investment or supplier tooling. The supplier may use a family mold, common base, standard insert, or proprietary process while the buyer funds only a custom component or setup.

A loan or temporary transfer. The buyer supplies its own tooling for use at the factory, retaining ownership throughout.

Collect the quotation, invoice, payment proof, tooling proposal, CAD files, mold-flow report, acceptance report, photographs, messages, and production records. Phrases such as “buyer-owned tooling,” “tooling deposit,” “amortized,” “refundable after volume,” “mold charge,” “maintenance,” and “remains at supplier” each point to a different arrangement — though labels alone are not conclusive without the surrounding deal.

Identify every physical asset before debating ownership

“The mold” may include more than one item:

• mold base, core, cavity, slides, inserts, and interchangeable components;
• jigs, fixtures, gauges, dies, cutting tools, and testing equipment;
• spare parts, maintenance kits, hot-runner components, and keys;
• master samples and inspection fixtures;
• CAD, CAM, mold-flow, CNC, and setup files; and
• modifications funded through later invoices.

The starting point is a tooling schedule recording a unique ID, description, product or part number, cavity count, material, dimensions, weight, completion date, current location, custodian, invoice reference, photographs, and condition for each item, with a mark showing whether the component is buyer-provided, buyer-funded, supplier-standard, or jointly funded.

Without that identification, even a strong ownership clause can fail operationally: a transfer team cannot collect “all buyer molds” if no one can distinguish them from hundreds of similar tools or tell which inserts belong to which base.

Separate five rights that contracts often collapse

1. Title to the physical mold

Title answers who owns the movable object. Under Articles 224 and 226 to 228 of the PRC Civil CodePRC Civil Code · Articles 224 and 226–228Transfer of rights in movable property generally takes effect upon delivery, with specific rules for prior possession, third-party possession, and agreements allowing the transferor to retain possession.Official text · SPC ↗ , delivery is central to transfer of rights in movable property , and the Code recognizes alternatives where the buyer or a third party already possesses the item or where the transferor retains possession by agreement.

That matters because tooling commonly remains at the factory. The contract should state whether the factory continues to hold buyer-owned tooling after title passes and on what basis, rather than leaving the timing of title to be inferred from payment alone.

Useful language identifies the exact event that passes title — full tooling payment, completion and acceptance, delivery, an amortization threshold, or another defined event. The right answer depends on who funded construction, who bears completion risk, and whether the tool incorporates supplier-owned standard components.

2. Physical custody and possession

A factory may perfectly well possess a buyer-owned mold in order to manufacture goods, but custody should then address location, access, relocation, subcontractor possession, labeling, segregation, care, risk of loss, maintenance, modification, and records.

Possession is evidence and leverage, but it is not always title; conversely, a buyer’s title does not mean it can safely enter the premises and remove equipment without a release process — contract and legal remedies should be used.

Where a person possesses property without authority, Article 235PRC Civil Code · Article 235A rights holder may request return of property from a person who has no right to possess it. Whether possession is unauthorized still depends on the contract, payment, defenses, and facts.Official text · SPC ↗  provides a return claim . The hard part is establishing the buyer’s right and answering any contractual or statutory basis for the factory’s continued possession.

3. Permission to use the mold

Even when the buyer owns the physical tool, the agreement should still state what the factory may do with it: production only for the buyer’s accepted orders, samples, testing, maintenance, spare parts, excess production, third-party production, and use after termination.

If limited test shots or maintenance runs are permitted, their scope should be defined, together with production records and the treatment of scrap, overruns, rejected units, and obsolete parts. For private-label or distinctive products, unrestricted use can undermine the buyer even without any formal transfer of title.

4. Intellectual property and design rights

Physical ownership is one thing; copyright in drawings, patent or design rights, trade secrets, know-how, and contractual use restrictions are several others. Articles 19 and 20 of the PRC Copyright LawPRC Copyright Law · Articles 19–20Copyright in commissioned work follows the parties' agreement; without a clear agreement it generally belongs to the commissioned creator. Transfer of a physical original does not itself transfer copyright.Official text · National People's Congress ↗  show why paying for and receiving a physical object does not itself settle copyright . For commissioned inventions, Articles 8 and 10 of the Patent LawPRC Patent Law · Articles 8 and 10Absent another agreement, rights to apply for a patent on a commissioned invention generally belong to the completing party; assignments of patent application rights or patents must follow legal requirements.Official text · National People's Congress ↗  make the contract equally important.

Identify:

• buyer background IP and supplied designs;
• supplier background IP, standard bases, and manufacturing know-how;
• newly created drawings, modifications, and inventions;
• ownership, licence, territory, field, exclusivity, sublicensing, and term;
• registration and assignment cooperation;
• third-party materials and infringement responsibility; and
• confidentiality and reasonable protection measures.

Trade-secret protection also depends on the information being non-public, commercially valuable, and subject to corresponding confidentiality measures under Article 10 of the Anti-Unfair Competition LawPRC Anti-Unfair Competition Law · Article 10The law prohibits specified improper acquisition, disclosure, and use of trade secrets and defines trade secrets as non-public, commercially valuable information protected by corresponding confidentiality measures.Official text · National People's Congress ↗ . A contract helps, but the buyer should also control access, markings, files, recipients, and disclosure records.

5. Return, release, and transfer rights

The contract should state when the factory must release tooling — expiry, termination, completed payment, buyer request, prolonged inactivity, supplier breach, insolvency risk, or another event — and define notice, cure, inventory, inspection, preparation, loading, transport, export documents, transfer cost, and condition at handover.

The factory may need reasonable time to stop production and prepare heavy equipment, and the buyer may need a replacement factory capable of receiving it. A release clause should be operational; “return immediately on demand” is not enough.

Can the factory retain tooling for unpaid amounts?

This issue requires precision rather than assumption. Where the arrangement is legally characterized as a work contract, Article 783 of the Civil CodePRC Civil Code · Article 783If the ordering party does not pay remuneration or material costs, the contractor may have a lien over the completed work or may refuse delivery, unless the parties have agreed otherwise.Official text · SPC ↗  provides that a contractor may have a lien over the completed work or refuse delivery when the ordering party fails to pay remuneration or material costs, unless the parties have agreed otherwise.

Several questions follow:

1. Is the tooling arrangement a work contract, sale, custody arrangement, lease, or mixed contract?
2. What remuneration or material costs are actually due?
3. Are the claimed amounts connected to the tooling or a different purchase order?
4. Has the buyer validly withheld, set off, or disputed the amount?
5. Did the parties agree to limit or exclude retention, and is that agreement effective in the circumstances?
6. Does another security, possessory, insolvency, or procedural issue apply?

A single sentence saying “supplier waives all liens” does not solve this. The contract should also identify title, payment completion, permissible claims, cross-order setoff, notice, evidence, security alternatives, release timing, and dispute procedure; a waiver may be useful, but it does not eliminate factual disputes over what is owed, what property is covered, or which legal relationship applies.

Nor should the factory’s assertion be accepted without support; ask for the contractual basis, invoice, calculation, due date, relationship to the identified assets, and authority for continued possession.

Maintenance, wear, and modification create separate disputes

Molds wear, cavities need repair, inserts are replaced, and engineering changes can alter value. The contract should state:

• expected tool life or shot count and what the estimate means;
• ordinary preventive maintenance included in unit price;
• approval and pricing for major repair or modification;
• maintenance logs, shot counts, and condition reporting;
• ownership of replacement components and modified drawings;
• responsibility for damage caused by misuse or poor storage;
• what happens when the mold reaches end of life; and
• treatment of scrap metal and disposal proceeds.

Because product, resin, cycle, and maintenance all affect wear, an absolute production life should not be promised; inspection, records, and agreed responsibility do the work instead.

If the factory modifies tooling without approval, the question is whether the change affects product conformity, regulatory status, interoperability, title, or IP. Change control should cover both the physical tool and its technical files.

Run a handover protocol, not an improvised pickup

Once release is due, the first step is a written inventory and sequence.

Confirm the legal basis. Identify the contract, title provision, payment status, release event, and any disputed amount, and keep settlement language out of an inventory receipt unless it has been reviewed.

Inspect and document. Photograph identifying marks, components, condition, corrosion, damage, shot counter, accessories, and files, and compare them with the tooling schedule and the latest maintenance record.

Agree logistics. Heavy molds may require cleaning, protective coating, crates, lifting, specialist transport, and export documentation, so state who pays and when risk transfers.

Collect digital and operational materials. Include CAD/CAM files, setup sheets, test reports, maintenance logs, keys, controllers, inserts, spare parts, master samples, and approved parameters where the buyer is entitled to them.

Use a signed handover record. Identify what was released, condition exceptions, date, representatives, vehicle or carrier, receiving location, and unresolved items, preserving the factory’s chop or authorized confirmation where appropriate.

Protect continuity. Where the agreement permits, test the tool at the receiving factory before treating the transfer as complete; a physically delivered but unusable mold shifts the dispute rather than solving it.

If the factory refuses to release the mold

An unsupported accusation of theft is the wrong opening move; build the claim in layers:

1. identify each asset and its current custodian;
2. establish what the tooling payment purchased;
3. establish title or another right to possession and release;
4. reconcile invoices, setoff, and alleged unpaid amounts;
5. identify the release event and contractual procedure;
6. demand preservation and prohibit unauthorized use or disposal where supportable;
7. propose a practical inventory and transfer date; and
8. follow the agreed court or arbitration route if refusal continues.

Urgent relief may be relevant if there is credible evidence the tooling will be moved, destroyed, modified, or used for competitor production, but availability, procedure, security, and forum all depend on the contract and the facts. A lawyer should assess preservation strategy before the buyer alerts the factory in a way that increases risk.

Damages may include provable and foreseeable costs caused by the breach, subject to causation, mitigation, agreed limitations, and applicable law. Under Articles 584 and 591 of the Civil CodePRC Civil Code · Articles 584 and 591Breach damages generally cover losses caused by breach within the foreseeability limit, while the non-breaching party must take appropriate steps to prevent unnecessary expansion of loss.Official text · SPC ↗ , foreseeable loss and mitigation both matter , so start replacement planning early and preserve quotes, lead times, testing costs, and customer consequences rather than assuming every business loss will be recoverable.

Put the tooling deal in a schedule before paying

A practical tooling schedule should cover:

• unique IDs, specifications, photographs, components, and location;
• builder, paying party, fee, payment status, and invoice references;
• what the fee purchases and when title passes;
• supplier-owned standard components and buyer rights to use them;
• custody, labeling, segregation, relocation, and subcontracting;
• permitted production, test shots, overruns, scrap, and post-termination use;
• maintenance, repair, modification, shot counts, and records;
• risk of loss, insurance if applicable, and damage responsibility;
• drawings, technical files, IP, confidentiality, and third-party inputs;
• qualifying unpaid amounts, notice, security alternatives, and retention limits;
• release events, inspection, packing, transport, costs, and risk transfer;
• handover documents, cooperation, and remedies; and
• governing law, forum, language, and notices.

The schedule should be kept current as new molds, inserts, or modifications are added; a master contract cannot identify equipment that operations never record.

Summary

The mold is never merely a production detail. It may carry a substantial payment, hold the buyer’s design, control the ability to switch factories, and become the supplier’s strongest leverage once the relationship deteriorates.

Paying the mold fee is evidence, not the whole legal answer. The asset, title, custody, permitted use, IP, unpaid-amount treatment, and release procedure should all be defined before the factory holds both the tooling and the buyer’s commercial leverage.
