# Tooling and mould ownership: how to protect the tools you pay for

Paying for a mould does not by itself make it yours in practice. To own and control tooling made by a supplier in India or China, sign a tooling agreement that names you as owner, pay for the tool separately, mark it with your ownership and tool number, record its shot life and condition, and agree in advance how and when you can move it to another factory.

## Key takeaways

  * Put ownership in writing, in a tooling agreement or the purchase order, before the tool is built.
  * Pay for tooling separately. Amortised tooling is often treated as the supplier's asset until fully paid.
  * Mark every tool with your name and tool number, and keep photos, drawings and a register.
  * Agree the guaranteed shot life, who maintains the tool and who pays for repairs and replacement.
  * Agree a transfer clause now: notice period, condition on handover and who pays to move it.

## Why tooling ownership causes disputes

Moulds, dies, jigs and fixtures are often the most valuable thing a buyer “owns” in a supplier’s factory, and the least documented. Disputes usually start when a buyer wants to move production: the supplier says the tool was never fully paid, or that the price included amortisation not yet recovered, or simply delays until the buyer gives up.

Nearly all of these disputes can be prevented with a short agreement, a clear payment structure and good records made at the start. This guide is general information, not legal advice; for high-value tooling, have a lawyer review your agreement.

## Write it down before the tool is built

A tooling agreement, or a tooling section in your purchase order, should cover:

Clause | What it should say  
---|---  
Ownership | The buyer owns the tool, including inserts and spare parts, once paid; the supplier holds it as custodian  
Identification | Tool number, part number, cavities, steel grade, maker, photo reference  
Price and payment | Total price and milestones; no further charges without agreement  
Use | Tool used only for the buyer’s parts; not lent, copied or used for others  
Shot life and warranty | Guaranteed number of shots (cycles) and what happens if it falls short  
Maintenance | Supplier does routine maintenance and keeps records; repair and replacement split  
Insurance and storage | Supplier insures and stores the tool properly while in its care  
Transfer | Return on request within a set notice period, in good working condition, with last-shot samples  
Drawings and data | Tool design files and drawings delivered to the buyer  
  
Many suppliers in India and China accept these terms readily, because they are standard with larger customers. A supplier who resists writing them down is telling you something.

## Pay separately, in milestones

Paying for tooling separately from parts makes ownership clear and keeps the part price honest. Common milestone structures:

  * **50/50:** half with the order, half on approval of first-article (T1) samples.
  * **40/30/30:** 40% on order, 30% on T1 samples, 30% on final approval after corrections.

If you prefer to amortise tooling into the part price, agree in writing the quantity it is spread over, what happens to the price once that quantity is reached, and what you owe if you stop ordering early. Without that, the supplier can fairly argue it has not been paid.

## What a tooling quote should contain

Tooling quotes vary wildly, and much of the variation is scope. Ask every toolmaker to state:

  * **Steel for cavity, core and inserts,** with hardness, and the mould base standard.
  * **Number of cavities** and whether it is a family mould.
  * **Runner system:** cold runner or hot runner, and the hot-runner brand if used.
  * **Cooling and ejection design,** and the expected cycle time it is designed for.
  * **Guaranteed shot life** and what happens if the tool falls short.
  * **Surface finish or texture** on each face.
  * **Design for manufacture review and mould-flow analysis,** if included.
  * **Trial rounds included** before T1, and the T1 sample quantity.
  * **Lead time to T1** and to final approval.
  * **Spare parts** supplied with the tool.

With these on paper, two quotes that differ by 40% often turn out to describe two different tools.

## Mark it, photograph it, register it

Ask for a metal nameplate on each tool stating “Property of [your company]”, with the tool number. Keep a register with:

  * Tool number, part number, cavities and steel grade.
  * Photos of the tool, nameplate and cavity side, taken at approval.
  * Location (factory, city) and custodian.
  * Shot count at each review and condition notes.
  * Date of last maintenance and any repairs.

Review the register at least once a year, and ask the supplier to confirm the shot count and condition. A tool that has been “lost” is much harder to argue about when you hold photos and a signed register.

## Shot life and maintenance

State the guaranteed shot life when you order the tool, along with the steel for cavity and core. A hardened-steel production mould and a soft aluminium prototype mould are different products at very different prices, and a quote that seems cheap may simply be the second kind.

Agree who pays for what:

  * **Routine maintenance** (cleaning, lubrication, minor polishing): supplier, as user of the tool.
  * **Wear repairs beyond the guaranteed life:** owner.
  * **Damage from misuse or poor maintenance:** supplier.
  * **Replacement at end of life:** owner, often with the supplier’s quotation compared against a should-cost. The [should-cost calculator](https://sourcesquid.co/tools/should-cost/) helps.

## Worked example: one mould, two pricing choices

A buyer needs a 2-cavity injection mould for a polypropylene container. The supplier offers two options.

| Option A: pay up front | Option B: amortise  
---|---|---  
Tool price | $9,000 in two milestones | $0 up front  
Part price | $0.37 | $0.46, including $0.09 per part for tooling over 100,000 parts  
Ownership | Buyer, from final payment | Supplier until 100,000 parts are bought  
Year one volume | 60,000 parts | 60,000 parts  
Tooling recovered after year one | Paid in full | $5,400 of $9,000  
If the buyer moves after year one | Tool leaves with notice | Supplier asks for $3,600 before release  
  
**Choice.** The buyer pays up front. Over 100,000 parts the total is the same, but Option A gives clear ownership from day one and a lower part price if volume grows beyond 100,000. The [MOQ vs price calculator](https://sourcesquid.co/tools/moq-vs-price/) and [make or buy calculator](https://sourcesquid.co/tools/make-or-buy/) help test the alternatives.

## At the end of a programme

Tools outlive products. When a part is discontinued, decide what happens to its tooling rather than leaving it in a corner of the factory:

  * **Keep it** in storage at the supplier, with an agreed storage period and a yearly condition check, if the part may return.
  * **Move it** to your own premises or another supplier if you want control.
  * **Scrap it,** with written authorisation from you and a scrap certificate with photos, so an old tool cannot quietly make parts for someone else.

Record the decision in the tool register. A tool that is neither used nor recorded is the one most likely to cause a dispute later.

## Transferring a tool to another factory

Moving a tool, for a second source or a change of supplier, is a small project. Plan it:

  1. **Check the agreement and payments,** and give written notice.
  2. **Run a last-shot sample** before the tool leaves, and keep the parts as the reference.
  3. **Record the condition:** photos, shot count, known repairs, spare inserts.
  4. **Crate, document and ship.** Moulds are heavy and valuable; use proper crating, rust protection and correct export paperwork.
  5. **Trial and approve at the new factory.** New machines, materials and settings mean a new first-article inspection and, usually, a new [golden sample](https://sourcesquid.co/intelligence/golden-sample-and-sample-approval/).

Budget time for the gap: the old factory stops when the tool leaves, and the new one cannot ship until it is approved. For high-volume parts, building a second tool is often better.

Tooling ownership: questions

## Straight answers.

Anything else, ask us directly. A principal replies, not a bot.

[anirudh@sourcesquid.co](mailto:anirudh@sourcesquid.co)

### Who owns a mould made by a supplier?

It depends on the contract and who paid. If you paid in full and your agreement says you own it, you own it. If tooling was amortised into the part price, or nothing was written down, the supplier may regard the tool as its own until the amortised amount is recovered. Put ownership in writing before the tool is built.

### Should I pay for tooling up front or amortise it?

Paying up front, typically in two or three milestones, makes ownership clear and lowers the part price. Amortising preserves your cash but spreads the cost over an agreed quantity; if you order less than that, expect the supplier to ask for the balance before releasing the tool.

### How do I move a mould from China to India?

Check ownership and the transfer terms in your agreement, give notice, agree the tool's condition and a last-shot sample before it leaves, arrange crating and export documents, and plan for trials and first-article approval at the new factory. Keep the old factory's last good parts as a reference.

### How long does an injection mould last?

It depends on the steel, the plastic, the design and maintenance. Hardened-steel production moulds can run for hundreds of thousands to millions of cycles; aluminium or soft-steel moulds far fewer. Agree the guaranteed shot life in writing when you order the tool.

### Who pays for mould maintenance?

Routine cleaning and preventive maintenance are usually the supplier's cost as the user of the tool. Repairs from normal wear beyond the guaranteed life, and replacement, are usually the owner's cost. Damage from misuse is the supplier's. Write this split into the tooling agreement.
