Custom Tooling Checklist for China Orders: Ownership, Storage, Maintenance and Transfer Rights

Before paying for custom tooling in China, define more than the tooling price.

You should document:

1. What you are paying for --- the complete mold, selected inserts, fixtures, tooling development or another service.
2. Who is identified as the contractual owner of the physical tooling --- and exactly when ownership is intended to transfer.
3. Who holds and maintains it --- including storage location, maintenance scope and records.
4. Who may use it --- including whether use is exclusive to your products and orders.
5. Which technical files are included --- and what rights you have to use or transfer them.
6. How modifications are approved --- and who owns new or replacement components.
7. How the tooling can be released or transferred --- if you change factories or end the supplier relationship.

Paying a tooling invoice, owning the physical tool, controlling its use and having access to its design files are separate questions.

A buyer-oriented tooling agreement should address these rights and operating responsibilities separately. InjeForm's tooling governance guide makes the same distinction between title, custody, permitted use, upkeep, access and release.

This checklist is a commercial preparation tool, not a legal contract template. Ownership, retention rights, intellectual property and transfer enforceability depend on the documents and applicable law. Have qualified counsel review material tooling arrangements before payment.

Do not accept a quotation that only says "mold fee" or "tooling charge" without defining the deliverable.

Tooling may include:

• injection molds;
• stamping dies;
• die-casting dies;
• extrusion dies;
• mold bases;
• cavities and inserts;
• jigs and fixtures;
• gauges and inspection fixtures;
• cutting tools;
• assembly fixtures;
• special-purpose equipment;
• tooling design and engineering;
• tooling modification or repair.

The buyer may be paying for a complete tool, a custom component added to an existing tool, or only the development work.

Checklist

Check What to confirm Evidence / notes

☐ Is the charge for a
complete new tool, a
partial tool, an
insert, a fixture or
engineering work?

☐ Is the tooling newly
manufactured or based
on an existing standard tool?

☐ Which components are
included: mold base,
cavities, inserts, hot
runner, spare parts,
gauges or fixtures?

☐ Is the tooling
dedicated to my product or shared with other
products?

☐ Are design,
engineering, testing,
trial production and
modifications included
in the quoted fee?

☐ Are maintenance,
repair, storage and
future replacement
costs included or
charged separately?

☐ Is the tooling fee
itemized separately
from unit price and
other development
costs?

Clarify the tooling payment model

Model What it means What must be documented

Buyer-funded Buyer pays all or a Ownership, payment tooling defined portion of the milestones, custody, tooling cost permitted use and transfer rights

Supplier-funded Supplier funds the Whether the buyer tooling tooling as part of its receives any ownership, manufacturing access or exclusive-use investment rights

Amortized tooling Tooling cost is Amount per unit, target recovered through unit quantity, ownership prices or a before and after the purchase-volume threshold, and commitment early-exit treatment

Shared / standard The tool or part of it Which components are tooling is used across products shared and which are or customers buyer-funded or exclusive

Modification / Buyer pays to change or Ownership of new repair restore existing components, design tooling changes, records and approval rights

Do not assume that paying a tooling fee automatically gives you ownership of the complete tool or every related component.

Ownership should be stated in the commercial documents rather than inferred from a payment record or verbal promise.

A tooling arrangement should identify:

• the legal owner of each physical tool;
• the event when ownership is intended to transfer;
• whether ownership depends on full payment or another milestone;
• whether any volume commitment affects ownership;
• whether the supplier has any retention or security rights;
• what happens if the manufacturing relationship ends.

Checklist

Check What to confirm Evidence / notes

☐ Does the agreement
explicitly identify who owns each tool?

☐ Is the ownership
transfer event defined?

☐ If ownership depends on full payment, is the
payment condition
clear?

☐ If tooling is
amortized, is ownership before and after the
volume threshold
defined?

☐ Are any supplier
retention, lien or
unpaid-cost claims
addressed?

☐ Does the tooling
agreement identify the
exact legal entity
responsible for the
tooling?

☐ If a separate mold shop builds or holds the
tool, is its role and
responsibility
documented?

Keep ownership and possession separate

The factory may physically hold a tool even if the buyer is intended to own it.

The agreement should therefore separately identify:

• Owner: who holds the agreed ownership rights.
• Custodian: who physically stores the tool.
• Operator: who is authorized to use it for production.
• Transfer recipient: who may receive it if production moves.

A useful question is:

If I own the tooling but the factory holds it, what documents and procedures allow me to access, inspect, use or transfer it?

For China-based tooling, a legal review may be important where ownership, unpaid balances, retention rights or enforcement are material. See Paying for Molds in China: What to Agree Before the Factory Cuts Steel for a China-focused discussion of these issues.

A broad statement that "all molds belong to the buyer" may be difficult to apply if the assets are not individually identified.

Create a tooling asset register.

Checklist

Check What to confirm Evidence / notes

☐ Does each tool have a
unique asset or mold
number?

☐ Is the tool linked to a specific product, SKU
and revision?

☐ Are the mold base,
cavities, inserts,
hot-runner parts and
spare components
listed?

☐ Are the tooling
manufacturer and
current custodian
identified?

☐ Is the physical storage location recorded?

☐ Are dated photographs
available?

☐ If agreed, is the tool
physically marked as
buyer-owned or assigned to the buyer's asset
number?

☐ Are the tooling
drawings and asset
register consistent
with the physical tool?

Suggested tooling asset record

Field Information to record

Tool ID Unique tooling identifier

Product / SKU Product made using the tool

Product revision Applicable product version

Tool type Mold, die, jig, fixture, insert or other

Tool components Base, cavities, inserts, hot runner and spare parts

Tooling manufacturer Company that designed or built the tool

Legal owner Entity identified as owner in the agreement

Custodian Company physically holding the tool

Storage location Factory and site address

Date completed Tool completion date

Acceptance status Trial / sample / final acceptance status

Related files Drawings, CAD files and technical records

Ownership does not automatically explain how a factory must store or maintain a tool.

The agreement should define the storage service and the maintenance responsibilities.

Storage checklist

Check What to confirm Evidence / notes

☐ Which factory and exact site will store the
tool?

☐ Who is responsible for
storage and physical
security?

☐ Is storage included in
the tooling fee or
charged separately?

☐ Is there a free storage period or a recurring
storage fee?

☐ What preservation
procedures are required during periods without
production?

☐ Is the buyer allowed to inspect the tool or
request an inventory?

☐ Who is responsible for
loss, theft or damage
while the tool is in
custody?

☐ Is insurance required,
and who arranges and
pays for it?

Maintenance checklist

Check What to confirm Evidence / notes

☐ Who performs routine
maintenance?

☐ Which maintenance
activities are included in the agreed fee?

☐ What maintenance
activities require
additional approval or
payment?

☐ Are cleaning,
lubrication, corrosion
prevention and
preservation procedures defined where relevant?

☐ Is tool usage or cycle
count recorded where
applicable?

☐ Are wear, repairs and
replacement components
logged?

☐ Does the supplier
provide maintenance
records when requested?

☐ Who pays for damage
caused by improper
storage or operation?

Maintenance requirements should be specific to the tooling type and production process. Avoid using a generic maintenance interval or tool-life figure without confirming that it is appropriate for the actual tool.

A useful maintenance log should record the tool ID, date, condition, work performed, replaced components, outstanding issues and responsible approver. InjeForm's tooling maintenance guidance provides examples of storage records, condition photographs and maintenance logs.

Even if the agreement identifies the buyer as the intended owner of the physical tooling, the permitted-use arrangement should be written separately.

For custom tooling funded by the buyer, consider whether the intended arrangement is exclusive use for the buyer's products and orders.

Checklist

Check What to confirm Evidence / notes

☐ Is the tool restricted
to producing the
buyer's specified
products?

☐ Can the supplier use
the tool for other
customers?

☐ Can the supplier use it for similar or
derivative products?

☐ Can the supplier
transfer it to an
affiliate or
subcontractor?

☐ Is prior written
approval required
before moving the tool
to another site?

☐ Are unauthorized
copying, production or
sale of products made
with the tool
addressed?

☐ Are photographs,
product displays and
online listings subject to agreed restrictions?

☐ Are there exceptions
for shared standard
components or jointly
funded tooling?

If the tool includes both standard factory components and buyer-funded custom inserts, distinguish them. A buyer may have exclusive rights to the custom portion without owning the supplier's pre-existing standard tooling or manufacturing know-how.

The physical tool and its related digital files are not necessarily the same asset.

Do not assume that paying for tooling automatically includes ownership of every design file, drawing, process document or item of manufacturing know-how.

Checklist

Check What to confirm Evidence / notes

☐ Are 2D engineering
drawings included?

☐ Are 3D CAD files
included?

☐ Are editable / native
files included where
required?

☐ Are neutral exchange
formats agreed where
appropriate?

☐ Are mold or tooling
design drawings
included?

☐ Are electrode data,
tooling component
drawings or other
relevant technical
files included?

☐ Are revision histories
and final approved
versions provided?

☐ Who owns the product
design and who owns the tooling design?

☐ Does the buyer have the right to use, modify or provide the files to
another manufacturer?

☐ Are confidentiality and permitted-disclosure
requirements defined?

Separate physical ownership from intellectual-property rights

The following questions should not be treated as equivalent:

• Who owns the physical mold?
• Who owns the product design?
• Who owns the tooling design or technical drawings?
• Who may use the CAD files?
• Who may modify the files?
• Can the buyer provide the files to a replacement manufacturer?

The agreement should state the intended ownership or license rights for each relevant asset and deliverable.

If files may be provided to a replacement manufacturer, also confirm any confidentiality, third-party intellectual-property, modification and permitted-disclosure restrictions. A tooling payment does not automatically create unlimited rights to every file or piece of manufacturing know-how.

Tooling may require maintenance, repair, adjustment or engineering changes during its useful life.

These activities should not be treated as one undifferentiated service.

Checklist

Check What to confirm Evidence / notes

☐ Is routine maintenance
distinguished from
repair and design
modification?

☐ Must the supplier
provide a written
description and
quotation before
material modifications?

☐ Who approves
modification scope and
cost?

☐ Who owns new inserts,
cavities or replacement components?

☐ Are removed or replaced components retained or
returned?

☐ Are revised drawings
and CAD files delivered after approved changes?

☐ Is the tooling asset
register updated?

☐ Does a material change
require a new sample or production validation?

☐ Are changes to tool
geometry, cooling,
surface finish or other critical features
subject to written
approval?

A modification record should include:

• reason for the change;
• affected tool ID and revision;
• description of the work;
• cost and schedule;
• approval record;
• affected drawings or files;
• post-modification sample or inspection result.

For injection molds, even a local change to a cavity, core, gate, vent or cooling circuit may affect the resulting part. The required review should reflect the specific tooling and product.

Transfer rights matter most when:

• the buyer changes manufacturers;
• the supplier stops producing the product;
• production capacity becomes insufficient;
• the commercial relationship ends;
• a second-source manufacturer is needed.

Do not wait until a supplier relationship deteriorates to discuss how tooling can be released.

Checklist

Check What to confirm Evidence / notes

☐ Does the buyer have a
documented right to
request transfer or
return?

☐ Which events allow
transfer: termination,
production
discontinuation, breach or buyer request?

☐ How much advance notice is required?

☐ Who is responsible for
dismantling and
preparing the tool?

☐ Who pays dismantling,
packing, freight,
insurance and handling
costs?

☐ Are any potentially applicable unpaid-cost, lien or retention claims addressed under the governing law?

☐ Is the tool's condition documented before
dispatch?

☐ Are loose inserts,
spare parts, gauges and accessories included?

☐ Are CAD files,
drawings, maintenance
records and process
documents handed over?

☐ Are export, transport
and receiving-factory
requirements
identified?

☐ Is a receiving
inspection or
requalification
required before
production resumes?

Define the handover package

A tooling transfer should include more than a freight document.

Where applicable, prepare:

• signed tooling asset inventory;
• tool ID and physical photographs;
• condition report;
• maintenance and repair history;
• current tool and product revisions;
• cavities, inserts and spare components;
• drawings and available digital files;
• approved samples or inspection records;
• packing list and transport documents;
• confirmation of receipt by the new custodian.

The receiving factory may need to check machine compatibility, process settings and sample conformity before production resumes.

A tool that has physically arrived at a new factory is not necessarily ready for production.

For additional practical guidance, see Injection Mold Ownership, Storage, and Maintenance: Contract Terms for Injection Molds, particularly its sections on custody, maintenance records and transfer handover.

Where tooling development involves multiple stages, consider tying payments to identifiable deliverables.

For example:

Milestone Possible evidence

Design approval Approved tooling drawings and specifications

Tooling construction progress Progress report and agreed production evidence

First trial / T0 Trial record and initial sample

Revised trial / T1 Updated sample and revision record

Final tooling acceptance Approved sample and agreed acceptance criteria

Final payment Completion of agreed deliverables and documentation

The actual payment schedule should reflect the tooling project and be agreed commercially.

If the tooling fee is amortized into product prices, separately document:

• total tooling value;
• amount recovered per unit;
• quantity threshold;
• cumulative quantity calculation;
• ownership before the threshold is reached;
• ownership after the threshold;
• early termination and buyout treatment.

Do not assume that a tooling charge described as "refundable after a certain volume" has the same ownership consequences as a separately purchased tool.

“Tooling fee,” “tooling amortization,” “refundable tooling charge” and “supplier-funded tooling” may create different ownership and transfer outcomes. Define the commercial mechanism rather than relying on the label.

Pause and clarify the arrangement if:

• the quotation says only "mold fee" without identifying the deliverable;
• the supplier will not state who owns the tooling;
• ownership is promised verbally but not documented;
• the factory holding the tool is not a party to the relevant agreement and has not acknowledged its obligations;
• the tool cannot be individually identified;
• storage and maintenance responsibilities are undefined;
• the supplier can use the tool for other customers without a clear agreement;
• design files are excluded but the buyer assumes they are included;
• tooling modifications can be made without buyer approval;
• the supplier refuses to define a release or transfer process;
• tooling ownership depends on an unclear purchase-volume commitment;
• payment, ownership and acceptance milestones contradict each other.

These are unresolved commercial and control issues, not automatic proof of misconduct.

Before authorizing payment, confirm:

SourcingX helps buyers discover and compare potential suppliers and conduct preliminary supplier due diligence using available supplier, company, product and public information.

When evaluating suppliers that require custom tooling, buyers should also record tooling as a separate commercial and technical consideration.

For example, compare:

• whether tooling is required;
• what the supplier says the tooling fee covers;
• whether the tooling scope is clearly itemized;
• which information about ownership, storage or transfer is still missing;
• what needs to be confirmed directly with the supplier.

SourcingX does not establish legal ownership of a mold, verify custody arrangements, interpret the enforceability of tooling clauses or replace legal review.

Also, do not assume that SourcingX automatically extracts or compares formal tooling quotations from emails, PDFs or RFQ responses. Formal quotation details and contractual rights must be reviewed against the actual documents.

Bottom Line

A custom mold or tool can become one of the most important assets in a long-term manufacturing relationship.

Before paying, make sure you can answer:

What exactly am I paying for?

Who owns the physical tool?

Who holds, maintains and uses it?

Which design files and technical rights are included?

Can I move it to another factory if the relationship changes?

The objective is not simply to obtain a promise that "the mold belongs to the buyer."

It is to establish an identifiable asset, documented rights, clear operating responsibilities and a workable transfer process before the tooling becomes difficult to recover.
