Tooling ownership and tooling transfer

Why ownership matters

A tool can outlast the supplier relationship. If the buyer owns it, the buyer can move it, ask for it back or place it with another supplier. If the supplier owns it, the buyer has a commercial relationship, not an asset. The difference becomes visible when quality slips, the supplier exits the product or the price needs to be tested.

Ownership also decides who pays for maintenance, repair and replacement. A worn die can cost a significant sum to rework. If the agreement is silent, the supplier may treat the repair as a reason to raise the piece price, or may refuse to run the tool until the buyer pays.

The subject is often confused with payment. A buyer that paid for a tool may assume it owns the tool. That is not automatic. The contract has to say so, and the supplier has to acknowledge it in a way that survives a change of management or ownership.

What counts as the tool

The tool is rarely one object. For a stamping, it may include the die, the die set, the springs, the sensors and the spare inserts. For a mould, it may include the mould base, the cavity and core inserts, the hot runner, the ejector system and the cooling circuits. For a wireform or assembly, it may include forming tools, fixtures, welding nests and test gauges.

The package also includes the intellectual content: the tool drawings, the CAM programs, the setting sheets, the qualification report and the maintenance history. Without those, a receiving supplier can own the steel and still be unable to run it to the same standard.

List the package item by item in an annex. Include the tool number, the part numbers it makes, the cavitation or station count, the machine size it fits, the weight, the dimensions and the location. A general statement that the buyer owns the tooling is not a pack list.

Payment models and ownership

Tooling is usually funded in one of three ways. The buyer pays upfront and owns the tool. The supplier funds the tool and recovers it in the piece price, often owning it until the cost is recovered. Or the cost is amortised across a volume and the ownership is agreed separately.

Each model has a different risk. An upfront payment gives the buyer a clear asset but ties up cash before the tool is proven. A supplier funded tool avoids the cash outlay but can make a transfer expensive, because the supplier may claim the remaining balance. Amortisation needs a clear record of the units shipped and the balance outstanding.

The table sets out the common positions. The important column is the last one: what the buyer can do if the relationship ends.

Marking, records and physical control

Mark the tool with a unique number and the buyer's name, where the tool allows it. Record its location and condition at the start of production. Photograph it before the first run and after each major service. Those records are evidence when the condition is disputed.

Keep the tool drawing, the material certificates for the cavity or die inserts, the heat treatment records and the qualification report. If the tool is modified, update the drawing and the record. A tool that has been changed without documentation may not produce the part the drawing describes.

For a tool held at a supplier, agree the access rights. The buyer may want the right to inspect, to audit maintenance or to place a label. Some suppliers resist any access. That is a signal about how a future transfer will be handled.

Keep a photograph of the tool number and the label with the agreement. If the supplier changes its name or moves site, the link between the contract and the physical asset can be lost. The photograph and the pack list are simple evidence that the tool in front of you is the one the contract describes.

When a transfer is triggered

A transfer can be planned or forced. Planned transfers happen at the end of a programme, when a product moves to another site, or when a second source is added. Forced transfers happen after a quality failure, a commercial dispute, a supplier insolvency or a loss of capacity.

The agreement should list the triggers and the notice period. A quality trigger needs an objective standard, such as a defined number of rejected lots or a failed audit. A commercial trigger needs a defined event, such as a failed price review or a change of control. Without a trigger, a transfer becomes a negotiation at the worst possible time.

Also decide who pays for the transfer. Packing, transport, insurance, any outstanding balance and the re-qualification at the new supplier can add up. Allocate them in the agreement, or at least state the principle before the event.

The transfer process

A tool transfer is a project, not a shipment. The steps below keep the hardware and the evidence together.

1. 01

   Agree the trigger and the date

   Confirm the contractual basis, the notice and the last production run.

2. 02

   Settle the balance

   Reconcile any amortisation, unpaid tooling charge or repair cost.

3. 03

   Audit the condition

   Inspect against the drawing, record wear and list missing items.

4. 04

   Pack and document

   Preserve surfaces, pack for transport and complete the pack list.

5. 05

   Ship and clear

   Agree the Incoterm, insurance and customs treatment of the tool.

6. 06

   Re-qualify

   Run samples at the receiving supplier and approve the parts before volume.

Condition, cost and the handover standard

A tool that has run for years is not new. The receiving supplier should know the wear state, the remaining life and the spare parts held. A condition report with measurements is more useful than a statement that the tool is in good order.

The handover standard should say what an acceptable tool looks like: cleaned, protected, complete with spares, with the latest drawing and the qualification record. If the tool needs repair before it can run, decide who pays before it leaves. A dispute at the receiving dock delays the whole transfer.

The receiving supplier will also need the process window. The setting sheet, the press or machine model, the cycle time and the inspection plan should travel with the tool. Without them, the new supplier starts from scratch and the first article may fail for reasons that have nothing to do with the tool.

A spare parts list is part of the handover. If the tool uses a standard spring or a bespoke insert, the receiving supplier needs the drawing or the supplier details. A tool that cannot be repaired because a single component is undocumented is not fully transferred, even if it runs on the first day.

What the agreement should say

Write the ownership clause, the pack list, the location, the maintenance obligation, the access right, the transfer triggers, the notice period, the cost allocation and the handover standard. Add a statement of any outstanding balance and how it is cleared.

Review the clause when the part, the volume or the supplier changes. A tool that was correctly documented at launch can become ambiguous after a modification, a site move or a change of supplier ownership. The record has to be maintained, not just signed.
