Mould, tool and tooling are three different things, and a contract that uses them loosely is one you will argue about later. A mould is the cavity. A tool is the whole system that makes the part. Tooling is the act and cost of opening it. Below: how to write ownership and refund clauses that hold up.
Quick answer
- A mould is the physical steel cavity; a tool is the complete system of cavity, core, cooling and handling.
- Tooling names the process and its one-time cost — “the tooling fee” is what you pay to open the mould.
- Always write ownership as “title and ownership transfers on payment of the full tooling fee”, never as “the mould is refundable”.
What is the difference between a mould and a tool?
In everyday packaging buying the three words are used interchangeably, which is why quotations from different factories can look comparable when they are not. In the industry they are not the same object.
| Word | What it actually means | What it is not |
|---|---|---|
| Mould | The physical cavity that forms the bottle — steel or aluminium, with the cavity, core and cooling channels | Not the whole production arrangement |
| Tool | The complete system: the mould plus the hot runner or manifold, the cooling and temperature control, the take-away and stacker mechanism | Not just the steel block |
| Tooling | The activity of designing, cutting and proving a tool, and the one-time fee charged for it | Not a recurring per-unit cost |
So “the mould fee” and “the tooling fee” often name the same money, while “the tool” is something physically larger than “the mould”. A factory quoting a low mould fee may charge separately for the hot runner. Ask what the number contains.
Is it mould or mold, and does the spelling change the contract?
Both spellings are correct, and the difference is regional rather than legal. British, Australian, New Zealand and most of Europe use mould. American, Canadian and international contract English use mold. Tooling is spelled the same on both sides.
| Term | British / EU usage | American usage | Note |
|---|---|---|---|
| The cavity | Mould | Mold | Same object, two spellings |
| The system | Tool | Tool | Identical word in both |
| The process and cost | Tooling | Tooling | Identical word in both |
| The drawing | Mould drawing | Mold drawing | Usually issued in English units either way |
| The fee | Tooling fee, tool charge | Mold fee, tooling charge | Often used as if interchangeable |
The risk is not that the spelling differs. It is that one party uses “mould” to mean the cavity and the other uses “tool” to mean the same cavity plus a hot runner, and only one of them is quoted. Whichever spelling you use, define the parts in the contract.
Who owns the mould once it is paid for?
Default ownership rules differ by jurisdiction, so do not rely on them. Where a contract is silent, the party that paid for a custom tool often has a claim to it, but the precise position varies and enforcement across borders is slow. The only reliable answer is a written clause.
| Ownership clause | What it means | Risk to the buyer |
|---|---|---|
| Nothing written | Default rules of the governing law apply | High — you may have paid for a tool you cannot remove |
| “Mould remains the property of the factory” | The factory keeps the tool after you stop ordering | You cannot move production if the relationship ends |
| “Ownership passes to the buyer on full payment of the tooling fee” | You own the tool once paid in full | Low — but the clause must be written this way |
| “Ownership passes on full payment; physical release within 30 days of written request” | You own it and can demand it back | Lowest — adds a delivery obligation to the factory |
A good ownership clause names four things: what transfers (mould, tool, drawings, hot runner), when it transfers (full payment), what happens on partial payment (ownership stays with the factory until the balance clears), and what happens if you stop ordering (it stays yours, stored or returned on request). Our standard wording is the third row plus a storage obligation — a tool in storage still needs periodic inspection, and that obligation should sit with whoever owns it.
What is the difference between refundable and creditable?
These three words describe different mechanisms and are routinely confused. A refundable fee is money that comes back. A creditable fee is money that comes back as product. A non-refundable fee is money that does not come back, though it may not have cost the factory anything extra either.
| Term | Mechanism | When it makes sense | What to check |
|---|---|---|---|
| Refundable | Cash returned, usually after a minimum cumulative order quantity | You want a hard cash refund and you will hit the threshold | The threshold quantity, the deadline, and the payment route |
| Creditable | Offset against future orders as a credit or as free units | You are unsure you will hit a cash threshold but will keep ordering | Whether the credit is per piece, per order, or a flat amount |
| Non-refundable | No refund and no credit | Modification of an existing tool, or a design the factory will not reuse | Whether the fee covers design, cutting and proving |
The practical difference is timing. A refundable fee depends on cash arriving after the threshold; a creditable fee depends on your next purchase order actually happening. Both are worthless if the relationship ends first, so state what happens if you stop ordering before the threshold.
Why do draw fees and tooling fees appear as two separate charges?
A draw fee is not a tool cost. It is compensation for the engineering and pattern work needed to make the physical mould, and it exists so that a factory can recover design time even if a project never reaches steel. A tooling fee is the cost of the tool itself: steel, machining, cooling channels, assembly and proving runs.
| Charge | Covers | Typically paid when | Refundable? |
|---|---|---|---|
| Product development fee | CAD, 3D modelling, drawings, structural review | Before any steel is cut | Sometimes creditable if the tool goes ahead |
| Draw fee | Pattern and sample making, iteration rounds before the tool | After drawings are approved, before cutting | Usually not, unless contractually stated |
| Tooling fee | The tool itself: steel, machining, cooling, assembly, proving | In instalments across the tool build | Only if a refund or credit clause says so |
| Modification fee | Changes to an existing tool: extra cavity, taller neck, new finish | With the tool still open | Normally not refundable |
| Sample or first article cost | Physical samples for approval | After the tool is proven | Charged separately from tooling |
Two consequences. A low tooling fee with a high draw fee may be the same money moved between lines. And the total you pay before the first sellable bottle is the sum of all of them, not the tooling fee alone. A new tool also carries roughly 30 working days of build time, so cost and schedule have to be read together. The fee structure is set out in custom bottle mould cost and sample time, and the refund question in is the mould fee a one-time charge.
How does first article approval relate to the mould?
First article approval is the moment the bottle stops being a drawing and becomes an accepted part. It is a quality gate, not a design gate, and it happens after the tool is built and proved, on samples pulled from the actual tool.
| Checkpoint | What is being checked | What happens if it fails |
|---|---|---|
| Drawing approval | Dimensions, capacity, weight target, neck finish, decoration area | Tool is built to the wrong intent — expensive to fix |
| First shot or trial sample | Does the tool fill, cool and demould correctly | Tool is adjusted before anything is shipped |
| First article approval | Capacity, weight, neck finish, decoration, drop and leak performance | Corrections in the tool, then a new first article |
| Golden sample | The single approved reference, signed and retained | Nothing ships without an agreed reference |
| Mass production release | Output of the first production run against the golden sample | Hold the run, re-inspect |
Written clearly, this protects both sides. If a change is requested after first article approval, reopening the tool is a new agreement, not a favour. If the first article was never formally approved and the buyer ships anyway, the buyer has accepted the part as made. Say in the contract which checkpoint unlocks mass production, and never let “please proceed” by email stand in for a recorded approval.
What are the risks of bringing your own mould?
Supplying a tool you already own is legitimate and often faster. The risks are practical, and mostly about documentation and condition rather than permission.
| Risk | What goes wrong | How to reduce it |
|---|---|---|
| Unclear ownership | The new factory disputes whether the tool is yours and refuses to run it | Written proof of purchase plus a serial or asset number on the tool |
| Unknown condition or history | Cavities are worn or previously modified; parts fail mid-run | Send cavity photographs and a condition report before quoting |
| Original drawings not transferred | The new factory cannot modify or repair the tool properly | Require the CAD files and drawings as part of any tool release |
| Insert or hot runner ownership | A replaceable insert is considered part of the factory’s equipment | List inserts, manifolds and cooling plates separately in the clause |
| Spare parts not supplied | A worn seal or nozzle stops the line and there is no spare | Agree on a spare kit and its cost when the tool transfers |
Where the relationship is new, weigh it against the alternative. Moving a working tool still needs process trials, first article approval and a re-established colour and decoration baseline. How that transfer works in practice is in if I switch suppliers, can I take my mold.
What are the three misunderstandings we see most often?
1. Treating “mould” and “tooling” as one line in the quotation. A quotation that says “tooling: USD 2,000” may exclude the hot runner, the cooling package and the proving runs. Compare quotations only after each has listed what the number contains.
2. Writing “mould refundable” with no threshold and no mechanism. Refundable against what, at what order quantity, by what date, through what payment route? Without those four, the clause is not workable and both sides assume the other will fund it.
3. Assuming first article approval is a formality. Approval before the tool is proved, or approval given verbally, transfers risk without transferring control. Fix the checkpoint in the contract and record it in writing.
What to write into a tooling clause before you pay anything
- Define the terms in the contract: state which parts constitute the mould and which constitute the tool, and that tooling means the process and its fee.
- List what the tooling fee includes: cavity count, steel or aluminium, hot runner or manifold, cooling package, assembly and proving runs.
- State what is charged separately: development fee, draw fee, sample or first article cost, and any modification fee.
- Write the ownership clause with a trigger: title transfers on full payment of the tooling fee, not on order or on shipment.
- Choose the refund mechanism deliberately — refundable, creditable or non-refundable — and state the threshold, deadline and payment route.
- Cover the early-exit case: what happens to the fee and the tool if you stop ordering before the threshold is met.
- Set out storage and inspection: who checks an idle tool, how often, and at whose cost.
- Name the approval checkpoints and state which one unlocks mass production and which requires re-approval after any change.
- Define the release mechanism: drawings, CAD files, inserts and spare parts transfer with the tool on written request.
- Record the modification rules in advance, including what a change after first article approval costs.
Frequently asked questions
Are mould and tooling the same charge?
Often yes in money, but not in meaning. “Tooling fee” is what you pay to open the tool; “mould” is the physical cavity. Ask for a breakdown so you know whether the hot runner and proving runs are inside the number.
Who owns the mould by default?
It depends on the governing law, and there is no universal answer. Write “title and ownership transfer to the buyer on full payment of the tooling fee” into the contract instead.
Is a refundable mould fee worth negotiating?
Worth writing down, less worth chasing. A refundable fee depends on you reaching a future order quantity. A creditable fee converts at your next purchase instead of waiting for a threshold.
What is the difference between a draw fee and a tooling fee?
A draw fee covers engineering and pattern work before any steel is cut. The tooling fee covers the tool itself: steel, machining, cooling, assembly and proving. Both are one-time.
Does first article approval lock the design?
It locks the specification, not ownership. Once the golden sample is signed, any change requires a new agreement. Approval should be formal, written, and reference the sample it approves.
Can I move a tool to another factory?
Yes, if you own it and the new factory accepts it in writing. Expect condition checks, process trials and a new first article approval.
