The tool outlives the order
A mould is not used up by a single production run. It goes on producing after the purchase order that paid for it has been filed, after the buyer’s second container has been sold through, and often after the person who negotiated the tooling has left the company. That long life is exactly why ownership has to be settled early. The buyer who commissioned a shape assumes it is theirs. The factory that cut the master assumes the tool belongs to the plant that built it. Both assumptions can be held in good faith, and in most purchase orders neither one is written down.
The commercial question is not who keeps a piece of plaster in a rack. It is who may use that shape again, for whom, and on what terms. Tool ownership is the mechanism. Control of the shape is the asset. A buyer who has not separated the two has left the most valuable part of a private label programme undiscussed.
What a ceramic mould actually is
In sanitaryware, “the mould” is not one object. A pattern or master is made first, and it carries the shape. Case moulds are taken from the master. Working moulds are cast from the case moulds and go onto the line. The working mould is a consumable: it wears as pieces are produced, its surface dulls, and it is replaced from the master again and again over the life of the product.
That chain matters because the pieces do not carry equal commercial weight. The master is the design in physical form, and it is the object that can regenerate the entire set. The working moulds are plant consumables, closer to a die or a grinding wheel than to an asset. A contract that says “the mould” without distinguishing between them leaves the most valuable object in the chain undiscussed, and it leaves the factory holding it by default.
Three things that can be owned, usually bundled into one word
A design project involves three distinct assets. Buyers and factories alike tend to compress them into a single noun, which is where the trouble begins:
- The design — the drawings, the dimensions, the profile, the shape as intellectual property rather than as an object.
- The tooling — the master, the case moulds, the working moulds, and any gauges, jigs or checking fixtures made specifically for that shape.
- The capacity to run it — kiln time, casting benches, glaze line, and the people who know how that particular shape behaves when it is demoulded wet.
Most disputes are not about the first item. A drawing is easy to establish as the buyer’s, because the buyer sent it. The argument sits on the boundary between the second and the third. A factory that owns the tooling can plausibly argue it may run that tool when the line is idle. A factory that owns only the process can plausibly argue it should not be asked to store and maintain a shape it is never allowed to use. Neither reading is unreasonable; only one of them will be written down.
The three boundaries a tooling agreement has to draw
The diagram below is the version of this we use when explaining the position to a buyer who is commissioning a shape for the first time. It separates what is yours, what is ours, and what is shared, and it is deliberately drawn as a chain rather than as a list, because the assets are created in sequence and each one inherits from the one before it.
Read the drawing left to right. The first box is the design and the drawing that carries it, and the boundary under it is marked as your design because that is the part a buyer brings to the table and can always prove. The second box is the tooling and the master, and the boundary under it is marked as a named owner, because the point of the clause is precisely that the owner has to be named rather than assumed. The third box is the finished product with its finish and firing, and the boundary under it is shared capacity, because that is where a factory’s kiln time, casting benches and glaze line enter the picture. A buyer who negotiates only the first box has negotiated the drawing and left the two things that actually reproduce it.
Where the ambiguity starts
Ownership is rarely disputed at the point it is agreed. It is disputed at one of four later moments, and each of them is a place where a missing sentence becomes expensive:
- At quotation, when a tooling line appears in the offer without a statement of who owns what it buys.
- At tooling payment, when the invoice is settled and nobody records what the payment purchased — a tool, or the right to use a tool.
- At sample approval, when the buyer signs off a shape and the sign-off is treated as a purchase rather than as an approval of a sample.
- At the end of the relationship, when the buyer asks for the tooling and the factory asks why it should release a master it has stored and maintained.
Only the last of those looks like a dispute. The first three are ordinary commercial moments, which is why they are missed. A tooling payment that does not say what it buys is the single most common origin of the argument, because it is the moment when money changes hands and no document follows it.
The clauses that settle it before it matters
Six statements are enough to remove almost all of the ambiguity, and none of them requires a lawyer to draft from scratch. What they require is that somebody insists on them before the master is cut:
- Ownership, stated per object. The design, the master, the case moulds and the working moulds should each be named, rather than covered by the word tooling.
- Custody, stated separately from ownership. A factory can hold and maintain a master that belongs to the buyer; holding is not owning, and the clause should say so.
- Reuse, stated as a permission rather than a silence. If the shape may not be produced for anyone else, say it. If the factory may run it, say under what conditions.
- Condition and maintenance, so that wear on a working mould is understood as normal and not as damage to be argued over.
- Transfer, meaning what happens physically if the relationship ends — who packs the master, who carries it, and what condition it is expected to be in.
- Duration, because a reuse restriction with no end date and one with an end date are different agreements, and the difference should be a decision rather than an oversight.
Written this way, the clause is not adversarial. It answers a question the factory also needs answered: what may be done with a shape that is sitting in the rack. A factory that cannot tell whether a tool is its own will either treat it as its own or refuse to invest in maintaining it, and both outcomes are worse for the buyer than a clear sentence.
What a factory may legitimately reuse
There is a distinction worth making, because buyers sometimes ask for more than ownership of a shape and factories sometimes defend more than they need. Process knowledge is not the shape. The way a plant casts a wall so that it releases cleanly, the way its glaze behaves over a particular radius, the firing curve that suits a body of a given thickness — none of that belongs to one customer’s design. It accumulates across every project the plant runs, and no reasonable tooling agreement tries to fence it off.
The exact geometry is different. A specific profile, a specific junction between pan and trapway, a specific rim form — those are the design, and they are what the buyer paid to have made. A factory is entitled to keep the experience of making it. It is not entitled to sell the result of it to somebody else, unless that was agreed. Most of the confusion in this area comes from buyers and factories using one word for both.
Our position, and how we put it in writing
We build tooling to a buyer’s drawings and we agree ownership before the master is made, not after the first container ships. Where a buyer commissions a shape, the tooling agreement names the master and the case moulds as the buyer’s, records that we hold them, and states what we may and may not do with them while we hold them. Where a buyer brings an existing design that was tooled elsewhere, the same conversation happens in reverse: we ask who owns the master, whether a copy exists, and what the previous factory’s release terms were.
The plant that does the work is in Chaozhou, Guangdong, where we have run our own ceramic production since 2021 — 51,000 m², 285 people, and a tunnel kiln on the same site as the casting, glazing and QC lines. That arrangement is relevant to a tooling discussion for a practical reason: when design, tooling, casting, glazing, firing and inspection happen inside one boundary, the shape is not handed between companies, and the number of parties who could reuse it stays small. It does not remove the need for the clause. It makes the clause easier to keep.
If you are commissioning a shape and want the ownership conversation held before anything is cut, send the drawing and the market you are selling into, and we will answer with the tooling position, the sample route and the documents your market expects — CE on the wall-hung models, WaterMark and the WELS rating where Australia is the destination, the AS 1976 absorption report, ISO 9001 for the plant, and SGS VOC reports where a project asks for them.

Frequently asked questions
Who owns the mould if the buyer paid for the tooling?
Paying for tooling does not automatically transfer ownership unless the agreement says it does. The payment buys the making of the tool; the ownership is a separate sentence. Put it in the tooling agreement before the master is cut, and name each object rather than writing “the mould”.
Can a factory use my shape for another customer?
Only if the agreement permits it, and silence is not a safe answer in either direction. A reuse clause should state whether the shape may be produced for anyone else, and if it may, under what conditions. Without that sentence the question is decided by whoever is holding the master.
What is the difference between a master and a working mould?
The master carries the shape and can regenerate the whole tooling set; it is the object that matters commercially. Working moulds are cast from case moulds and go onto the line, where they wear and are replaced. A clause that covers “the mould” without naming the master has not covered the asset.
Should the tooling be transferred if we change supplier?
That is a commercial decision, and it should be made when the tooling is commissioned rather than when the relationship ends. If transfer is intended, the agreement should say who packs the master, who carries it and what condition it is expected to be in on handover.
Does a tooling clause protect the design itself?
It protects control of the physical means of production, which is a different thing from owning the design as intellectual property. A tooling clause is worth having even where formal design protection exists, because it operates at the factory rather than at a registry.
How long does tooling take, and does that affect the clause?
Tooling sits ahead of sampling, and sampling ahead of the production lead time of 30–40 days, so the clause has to be agreed at the start of the project rather than alongside the first order. Anything settled later is settled after the master already exists.
