You’d assume that when you pay $20,000 for an injection mould, you own a $20,000 mould. Most Chinese contract manufacturers operate on a different assumption. The disagreement only surfaces months or years later, usually in one of three scenarios:
- You try to switch factories and discover the moulds aren’t yours to move.
- A competitor’s version of your product appears on Alibaba, made on the tooling you paid for.
- You’re handed a transfer bill that wasn’t on the original quote, sometimes 15 to 30% on top of what you originally paid for the tool itself.
Tooling ownership is the single most common procurement issue most founders never think about until it bites them. It’s also one of the easiest things to get right at the start of a relationship, and one of the hardest to fix retroactively. This piece covers what tools actually cost, why the misunderstanding happens, what your supplier privately believes they own, what Chinese law actually says, and the contract structure that prevents the problem in the first place.
What tooling actually costs
The numbers matter because they explain why factories treat tooling as more than a setup expense. For injection moulding produced in China in 2025, typical ranges are:
- Simple single-cavity mould: $5,000–$20,000
- Medium-complexity production tool: $20,000–$50,000
- High-precision or multi-cavity: $100,000 and up
Most moulds for SME hardware brands sit in the $1,000–$10,000 range, with machining labour alone accounting for 40–50% of the total cost. Steel grade is a major variable: P20 is the baseline; H13 adds 25–40% to the steel cost; S136 adds 60–90%.
For metal stamping tooling, the range is broader still — a single die for a complex part can run $30,000–$80,000, and tooling sets for products with multiple components multiply quickly. The point isn’t the exact number for any one product. The point is that the line item labelled “tooling cost” on your quote is the price of a real industrial asset, not a setup fee. Treating it as the latter is how the trouble starts.
Failure mode one: your supplier starts selling your product
This is the scenario every hardware founder fears, and it happens more often than gets reported. The factory has the tool, has the BOM, knows how to run the line. If your orders dry up or your relationship sours, they have a finished production capability sitting on the floor with nothing to make. From their commercial logic, running the tool for a different buyer recoups the floor space and machine time.
You may never find out. Knockoffs appear on Alibaba or Amazon under different brand names. They are physically identical to yours because they are made on the same tool, by the same operators, on the same line. The legal route (proving the factory infringed your design) is slow, expensive, and only available if you registered the IP correctly in China — a topic we cover separately in our related piece on protecting your product design in China. The faster route is to never let the situation arise: make sure the tooling can’t be used to produce parts for anyone but you.
Failure mode two: you try to switch factories and discover the tooling was never yours
Three years into manufacturing, you find a better supplier. Quality at the original factory has slipped, lead times have stretched, and a competitor has just placed a large order with the same factory, pushing your runs down the queue. You call to arrange a tooling transfer.
The factory agrees in principle. Then comes the invoice. Across documented industry cases, the surprise sits in the range of 15% to 30% on top of the original tooling price, charged as a “release fee,” a “refurbishment fee,” or a “transfer preparation charge.” Sometimes higher. You can pay it, or you can spend six months in dispute while your inventory runs out.
The factory’s position, often unspoken: you paid a setup fee that entitled you to produce with the tool while you remained their customer. If you leave, the tool stays. They view the tooling as security for ongoing business and as a bargaining chip when terms need renegotiating. Without an explicit contract that says otherwise, this is a defensible position under Chinese commercial practice.
Failure mode three: the costs nobody mentioned upfront
Even when the relationship is fine, tooling generates a steady stream of unexpected charges that aren’t always illegitimate but are almost never disclosed upfront:
- Tool maintenance fees — retroactive charges for upkeep the buyer didn’t know was billable
- Storage fees if the tool sits idle between production runs
- Refurbishment fees when a tool nears the end of its life, sometimes presented as mandatory before further production
- “Readiness” charges added to any urgent order
- Modification fees every time the design needs a tweak, even minor
C2W’s FAQ guidance on this is direct: the biggest mistake clients make when budgeting for China manufacturing is underestimating hidden costs (moulds, reworks, tariffs, compliance testing). Those costs are real. They become a problem only when they’re surprises.
What Chinese law actually says about ownership
Under Chinese law, ownership of goods transfers on delivery unless the parties have agreed otherwise. The mould you paid for almost never leaves the factory floor. It is built in the factory’s toolroom (or commissioned by the factory from a third-party toolmaker) and stays there. Without a written agreement explicitly transferring title to you, ownership is at minimum contestable.
To establish enforceable ownership, you need a manufacturing or tooling agreement that:
- Identifies each tool by serial number, dimensions, and photographs
- States explicitly that the buyer owns the tooling
- Grants the buyer inspection rights at any time, with reasonable notice
- Includes a clear contractual duty for the factory to release or transfer the tool on request
- Specifies that the factory holds the tool in custody only, not as owner
- Prohibits the factory from using the tool for any third party
The contract should be in Chinese, written by a lawyer who specialises in Chinese commercial law, and ideally structured as a separate tooling agreement alongside the production contract. Bolt-on clauses inside a production PO are weaker than a standalone tooling document.
How C2W structures it for hardware clients
In 21 years and over 15,000 projects, we’ve seen every variation of the tooling-ownership question. We know the local law, the hidden tactics factories use when an order book gets shaky, and the contract structures that prevent them. Transparency and integrity are how we work, not a tagline. In some cases, we’ve even helped customers export their tools out of China entirely, back to US toolmakers for local production runs.
The practical playbook we apply on every project:
- Tooling ownership is one of the 11 clauses in every C2W production contract. The factory signs the production PO, but a separate tooling agreement runs alongside it, naming each tool by ID and stating the buyer’s title.
- Every tool is logged at handover. Serial number, dimensions, photographs, condition report, and storage location captured the day the tool is finished.
- A documented exit plan exists from day one. Every tool has a written transfer route (which logistics partner, which customs broker, which destination) even if it’s never used. The factory knows we know how to move the tool.
- Penalty clauses for non-release. The contract includes liquidated damages if the factory withholds release after the buyer’s written notice. This converts a standoff into a contract dispute, which is much faster to resolve.
This isn’t extra paperwork. It’s standard procurement discipline for any hardware brand that intends to be in business in five years.
The cleaner setup: factory holds the tool, you own it
There’s a structural improvement worth raising. Most Chinese contract manufacturers either build the tool in their own toolroom (which makes ownership messy to claim later) or outsource it to a third-party toolmaker and store the finished tool on their floor (which is cleaner but rarely documented).
The cleanest arrangement: have your supply chain partner commission the tool directly from an independent toolmaker, take legal title at handover with paperwork in your name, and place the tool with the production factory under a custody (not ownership) agreement. The factory makes parts. You own the means of production. They never had standing to claim the tool in the first place. This is the structure C2W uses with All-In Supply Solutions engagements where the production factory is one of several touchpoints in a managed supply chain.
What to do tomorrow
Three actions you can take this week:
- Read your current contract. If the word “tooling” or “mould” doesn’t appear, you don’t have ownership documented. Most boilerplate manufacturing agreements skip it entirely, and most factories will not raise the question.
- Photo and serial number every tool you’ve already paid for. Do it now, with the factory’s cooperation, before anything goes wrong. Building the asset register is the foundation of every later dispute.
- Get a separate tooling agreement drafted. A China-law specialist, in Chinese, with title transfer, identification, custody, release, and penalty clauses. The document runs four to six pages. The cost is a fraction of one tool.
If you’d rather not work through this on your own, that’s what we do. Get in touch and we’ll review your current tooling exposure as part of scoping the engagement.
