Quick answer: if you send original artwork, CAD files, character designs, packaging, tooling instructions or other confidential product information to a supplier, do not assume that a normal purchase order, sample payment or generic NDA automatically settles who owns the design or whether the supplier may reuse it. Before sensitive files or custom tooling are released, identify the supplier’s legal entity and define in writing what the buyer already owns, what the supplier may use, who owns newly created work, whether the product or tooling is exclusive, how subcontractors are handled, and what happens to files, molds and confidential information when the project ends.
Will a Chinese manufacturer automatically keep my custom product exclusive?
No automatic assumption should be made. An existing supplier product with your logo or packaging is normally a different commercial situation from an original buyer-owned product developed from drawings, artwork or custom tooling. If exclusivity matters, define exactly what is exclusive, for which product/design, territory, channel, customer group and time period, and make it part of the written supplier agreement rather than relying on a sales message.
What should be separated before sharing the design?
| Item | Question to settle |
|---|---|
| Background IP | What artwork, brand assets, drawings, CAD, characters, packaging or know-how did the buyer already own before the project? |
| Supplier background IP | Is the supplier contributing an existing mechanism, stock mold, process, component or design platform that it already uses for other customers? |
| New project output | Who owns new drawings, patterns, prototypes, CAD revisions, mold designs, packaging files or improvements created during development? |
| Permitted use | May the supplier use the buyer’s files only to quote, only to sample, or also to manufacture specific purchase orders? |
| Exclusivity | Is the restriction about the exact design, a market/channel, named competitors, tooling use, or all production for a defined period? |
| Subcontracting | May specialist factories or service providers receive the files, and what confidentiality/use restrictions follow them? |
Is an NDA enough for a custom manufacturing project?
A confidentiality agreement can be useful, but confidentiality is only one issue. A manufacturing relationship can also require clear terms for non-use, ownership, licensing or assignment of newly created IP, tooling, permitted production, subcontractors, overruns/seconds, return or destruction of materials, and dispute resolution. WIPO’s supplier-IP guidance similarly separates confidentiality from ownership, permitted use, assignment/licensing and end-of-contract controls.

If I pay for a mold or tooling, do I automatically own and control it?
Do not rely on payment alone to answer that question. The written project terms should identify who owns the physical mold/tooling and related design files, where it is stored, who may use it, whether it may be moved, how maintenance or replacement is handled, whether the supplier may produce overruns or samples for other parties, and what happens to the tooling when the supplier relationship ends.
What if the supplier already sells a similar product?
Separate the supplier’s existing product platform from the buyer’s new contribution. If the supplier already owns a stock mold or generic mechanism, the buyer should not assume that adding a logo, color or package makes the underlying product exclusive. If the buyer contributes original artwork, a new structure, custom molded parts or a new character, define which elements are buyer-controlled and which remain supplier background IP.
What if the supplier also sells under its own brand or competes on Amazon?
Treat that as a commercial conflict question before sharing the most sensitive files. Ask whether the supplier sells the same category directly, whether it has a policy for customer-specific designs, how buyer files are separated from its own branded development, whether subcontractors can reuse the files, and whether any requested exclusivity can be written precisely enough to be audited. A supplier’s promise of “confidentiality” should not replace a clear scope.
Should I send the full CAD or artwork before the supplier is verified?
Share enough information for the stage of the project. Early capability screening may only require the product category, key material/process, approximate dimensions, function and non-sensitive reference information. More sensitive CAD, artwork, character files or production data can be staged after the correct legal entity, development route and confidentiality/IP terms are understood. Some products cannot be quoted accurately without detailed files, so the practical disclosure sequence must fit the project.
What should a supplier IP / manufacturing agreement clarify?
- Correct contracting legal entity and official contact information.
- Buyer background IP and supplier background IP.
- Ownership of new drawings, prototypes, packaging, software/firmware or improvements created for the project.
- Exactly how buyer files and brand assets may be used.
- Whether exclusivity exists and its product, territory, channel, customer and time scope.
- Tooling/mold ownership, use, storage, maintenance, transfer and end-of-project handling.
- Restrictions on overruns, seconds, rejected units, samples and unauthorized sales where commercially required.
- Subcontractor access and confidentiality/use obligations.
- Return, deletion or destruction of confidential physical and digital materials at termination where applicable.
- Applicable law, dispute-resolution process and the language/version of the agreement to be relied upon.
WIPO recommends that supplier arrangements clarify ownership, access/use, confidentiality, assignment/licensing, termination/return of materials and dispute resolution. The EU China IP SME Helpdesk also advises businesses to verify the legal entity they are contracting with and to spell out ownership and confidential-information controls in written agreements.

Can any supplier guarantee that nobody else will ever copy my product?
No realistic sourcing process can guarantee that. Supplier controls are one layer of an IP strategy, not a substitute for appropriate trademark, copyright, design/patent, trade-secret or marketplace protections where those are relevant. The right protection depends on the asset and the markets involved. For commercially important designs, obtain qualified IP/legal advice before relying on a contract template or online forum advice.
Jinyu Project Boundary
Jinyu distinguishes existing-product customization from buyer-owned development. A stock product does not become exclusive merely because a buyer adds a logo or private-label package. For projects involving confidential original artwork, character designs, CAD, custom structures or tooling, ownership, permitted use, specialist-partner access and any requested exclusivity should be identified before sensitive development work proceeds. Jinyu does not treat a third-party reference image as proof that the buyer owns the underlying character or design rights.
