Practical Answer — Manufacturing Agreements

How Do I Ask a Chinese Factory Who Owns the Mold or Tooling?

Q: What should I ask the factory before paying the tooling fee?

Ask: (1) Will the invoice confirm that I own the mold after payment? (2) Where will the mold be stored and who is responsible for it? (3) Can the mold be transferred to another factory if I change suppliers? (4) Will the factory agree not to use the mold for any other customer or product? These questions do not need to be confrontational — they can be framed as standard manufacturing process questions that any buyer with an internal compliance requirement would ask.

Q: What documents should state who owns the mold?

The tooling invoice should state that the mold is being purchased by the customer and that ownership transfers upon payment. The purchase order should reference the mold and confirm customer ownership. The manufacturing agreement should include a clause on mold ownership, custody, permitted use, prohibited use for other customers, return process, and what happens to the mold if the manufacturing relationship ends.

Q: What are red flags in the factory's response to mold ownership questions?

Key red flags: the factory refuses to put ownership language into the invoice or agreement; the factory says the mold 'belongs to the project' or 'stays with us for safekeeping' without a written return mechanism; the invoice is for 'tooling cost' or 'mold development fee' without stating ownership transfer; the factory says mold transfer would be subject to outstanding balances without specifying what those are; or the factory becomes defensive when the question is raised in writing.

Ask before the tooling fee is paid. Frame it as a standard process question. What matters is not the factory's verbal answer — it is what the invoice, PO, and manufacturing agreement say.

In short

Raise mold and tooling ownership before paying the tooling fee — not after. Frame it as part of your standard purchasing process, not as a sign of distrust. What the factory says verbally is less important than what the tooling invoice, purchase order, and manufacturing agreement say in writing. If ownership is not clearly stated in the documents, it is not clearly established.

Why Paying for Tooling Does Not Always Mean You Control It

This surprises many buyers. You paid for the mold — sometimes a significant amount — so surely you own it. In practice, it depends entirely on documentation:

Payment and ownership are legally separate

A tooling fee payment records that money changed hands for mold development. It does not, by itself, record that ownership of the physical asset transferred to the buyer. Chinese courts and arbitration look at what the contract, invoice, and PO say — not just at payment records.

Invoices are often vague

Many tooling invoices read as 'tooling cost' or 'mold development fee' — amount, bank account, done. This records payment. It does not record ownership transfer, storage obligations, transfer process, or permitted use. A vague invoice gives the factory significant room to argue ownership terms were never defined.

Physical custody is not the same as ownership

The factory holds the mold because it needs to use it for production. Physical custody at the factory's premises does not mean the factory owns it — but it does mean that if a dispute arises, the factory has the practical advantage of possession.

Factories use molds as leverage

A factory that does not have clear written obligations about mold release, transfer, or return may hold the mold as negotiating leverage when a buyer tries to switch suppliers or renegotiate pricing. The time to address this is before you are in that position.

What to Ask Before Paying the Tooling Fee

Before transferring any tooling payment, ask the factory the following — in writing, by email:

Will the tooling invoice state that I own the mold after payment?
Where will the mold be stored, and will the factory confirm I can inspect it at any time?
If I need to transfer the mold to another factory in the future, what is the process and who bears the cost?
Will the factory confirm in writing that the mold will not be used for any other customer's product or for the factory's own product lines?
What happens to the mold if the manufacturing relationship ends — return, transfer, or destruction?
Will these terms be included in the manufacturing agreement or tooling agreement?

How to Ask Without Sounding Accusatory

Most factories are not trying to steal your tooling — they just have not thought about ownership documentation in the same way a buyer needs to. Frame the question as a standard process:

Process framing

"Our purchasing process requires us to confirm mold ownership and custody terms before any tooling payment is approved. This is a standard step for our team — not specific to this project. Can you confirm how this is usually handled on your side?"

Invoice request

"For the tooling invoice, can you make sure it confirms that the mold will be customer-owned after payment? Our accounts team needs that on record before the payment can be authorized."

Agreement reference

"We would like the manufacturing agreement to include the mold ownership, custody, and transfer terms before we move into production. This protects both sides — is that something your team can accommodate?"

What Answers Are Acceptable

A cooperative, professional factory response should include:

Willingness to issue an invoice that states the mold is customer-owned after payment
Confirmation of where the mold will be stored and agreement to allow inspection
Agreement not to use the mold for other customers — in writing
Willingness to include these terms in the manufacturing agreement or a separate tooling agreement
A clear answer on the mold transfer process — even if the details need to be agreed in writing

Red Flags in the Factory's Response

Watch for these responses:

"Of course you own it — don't worry" with no willingness to put it in writing: verbal assurance without documentation is not protection.
"The mold stays here for safekeeping" with no agreed return or transfer mechanism: physical custody without a release obligation gives the factory significant leverage.
The invoice reads only "tooling fee" or "mold development cost" with no ownership statement: a vague invoice leaves ownership legally undetermined.
"Mold transfer is subject to any outstanding balance" without specifying what that includes: this is a mechanism for holding the mold indefinitely.
Refusal to discuss the topic or deflection to a later stage: ownership questions raised after the tooling fee is paid are significantly harder to resolve.

What Should Be Written Into the PO, Invoice, or Manufacturing Agreement

Across the tooling invoice, purchase order, and manufacturing agreement, the following should be stated:

Tooling invoice

Customer name as owner. Mold description or ID. Statement that ownership transfers to the customer upon full payment. Factory's obligation to hold the mold for the customer's exclusive use.

Purchase order

Reference the mold by ID or description. State that the mold is customer-owned. Include the PO as part of the documentation trail for ownership.

Manufacturing agreement

Explicit ownership clause stating the customer owns the mold. Custody and storage terms — where the mold is held, who is responsible for it, and inspection rights. Prohibition on using the mold for other customers or products. Transfer process — logistics, cost allocation, and what constitutes a completed transfer. What happens to the mold if the relationship ends: return, transfer to a new factory, or destruction.

When to Move to a Tooling Ownership Agreement or Supplier Control Review

Consider moving to a formal tooling agreement or requesting a China Supplier Control Review if:

The tooling fee is material and the factory has not agreed to ownership language in the invoice or agreement
You are moving into production but ownership terms have never been addressed in writing
The factory is resisting any written confirmation of mold ownership, custody, or transfer terms
You already paid the tooling fee and now want to clarify the ownership position before a dispute arises
You are changing suppliers and need to understand your practical options for transferring or reclaiming the mold

Frequently Asked Questions

Does paying the tooling fee mean I own the mold?

Payment is evidence that you funded the mold, but it does not automatically establish legal ownership. In China, ownership depends on what the contract and supporting documents say. If the tooling invoice, PO, and manufacturing agreement do not state that the customer owns the mold from the point of payment, the factory may argue ownership was never formally transferred.

What should I ask the factory before paying the tooling fee?

Ask: Will the invoice confirm customer ownership after payment? Where will the mold be stored? Can it be transferred to another factory if I change suppliers? Will the factory agree not to use the mold for any other customer? These are reasonable questions that any buyer with a standard purchasing process should ask.

What if the factory says 'of course you own it, don't worry'?

A verbal assurance is not the same as a written ownership term. What matters is what the tooling invoice, purchase order, and manufacturing agreement say. Ask for the ownership position to be reflected explicitly in the documents — before payment is made.

What documents should state who owns the mold?

The tooling invoice should state ownership transfer upon payment. The purchase order should reference the mold and confirm customer ownership. The manufacturing agreement should include clauses on mold ownership, custody, permitted use, prohibited use for other customers, return process, and what happens if the relationship ends.

What are red flags in the factory's response to mold ownership questions?

Key red flags: refusal to put ownership language into the invoice; the invoice reads only 'tooling fee' without an ownership statement; the factory says the mold 'stays here for safekeeping' without a written return mechanism; mold transfer is said to be 'subject to outstanding balances' without specification; or the factory becomes defensive when the question is raised in writing.

What happens to the mold if I switch factories?

If the manufacturing agreement addresses mold transfer, that governs. If it does not, the transfer can become contentious. The right time to address transfer terms is before production starts. A manufacturing agreement should include the transfer procedure, who arranges logistics, who bears cost, and the inspection or acceptance process.
