Who owns the mould when a Chinese factory makes it

Who owns the mould is decided by what the tooling agreement says, not by who paid the invoice, and buyers are regularly surprised by the gap between the two. Paying for a tool buys a tool that has been made. On its own it does not transfer title, hand you the drawings, or get the tool out of the building it sits in.

Why paying for tooling does not by itself transfer ownership, what the agreement has to say, and why possession of the tool matters as much as title to it.

Paying for a tool and owning it are different things

A tooling invoice records that money changed hands for work done. Ownership is a separate question that only the written agreement answers, and many tooling quotations are silent on it. Silence is not neutral: it leaves the tool with the party holding it, and that party is the factory.

  • Ownership passes when the agreement says it passes, not on payment
  • A quotation that never mentions title is the common starting point
  • Silence favours whoever has the tool in their building

Title on paper, possession in fact

Even a clear ownership clause leaves the tool bolted into somebody else's press, in another country, under somebody else's control. Buyers who assume a clause alone will produce the tool on demand are usually the ones who discover otherwise during a dispute, when the tool is exactly the leverage the other side has left.

  • Ownership decides who is right; possession decides who waits
  • The tool is most likely to matter at the moment relations are worst
  • Plan for the tool being unavailable during any disagreement

What the agreement has to state

The clauses that prevent tooling disputes are unglamorous and short. Each tool identified individually, the moment ownership passes, physical marking, an acknowledgement that the supplier holds the tool for you rather than owning it, and what happens to the tool when the relationship ends. Our tooling agreement checklist sets these out line by line.

  • Each tool identified by part name, drawing number, revision and cavity count
  • The point at which ownership passes, in plain words
  • Marking with your name or asset number, and who applies it
  • A written acknowledgement that the supplier holds the tool for you
  • What happens to the tool on termination, and who pays to move it

What moving a tool actually involves

Transfer is a physical and technical exercise, not a paperwork one. Tools are heavy, they are built around a particular press and a particular set of ancillary equipment, and they arrive at a new factory needing inspection and often refurbishment before they run. A tool that has produced for two years is not the tool that was signed off.

  • Expect inspection, trials and refurbishment at the receiving factory
  • Ask for the tool drawings and the maintenance record, not only the tool
  • Budget the move and the requalification, not just the transport

Where this stops being our subject

Ownership, intellectual property and contract enforcement are legal questions and we do not answer them. We are not lawyers, we give no legal opinion on title or on design rights, and nothing here is advice on your agreement. What we can do is physical and factual: confirm a tool exists, that it is marked, that it matches the drawing revision you think it does, and that it is where you were told it is.

  • No legal opinion on ownership, IP or enforcement, ever
  • We can verify the tool exists, is marked and matches the stated revision
  • Design protection is registered through the routes WIPO describes, with your own adviser

Before the tooling payment leaves

Everything above is cheap to settle before the money moves and expensive to settle afterwards. The tooling payment is usually the largest one a private-label buyer makes before a sellable unit exists, which makes it the wrong payment to make on a quotation alone.

  • Get the ownership and holding clauses in writing before paying
  • Photograph the tool marked with your asset number
  • Keep the drawing revision that the tool was cut to
