Is a China NNN agreement enough on its own for hardware founders?

An NNN is the right starting point, but for hardware founders it often needs to be supplemented. Tooling and mold ownership are not typically covered in an NNN — they require a manufacturing agreement or separate tooling PO with explicit ownership terms. Production file ownership, design improvement rights, and product specification control should also be addressed in a manufacturing or OEM agreement as the relationship moves toward production. The NNN protects the disclosure phase; a manufacturing agreement protects the production phase.

When should the NNN be signed in the supplier engagement process?

Before any sensitive product information is shared. This means before CAD files, STP files, detailed product specifications, BOM, PCB information, firmware notes, or prototype samples are sent. Initial contact (product category description, function, approximate volume) can happen before the NNN, but anything that reveals the design's detail or commercial value should wait until the NNN is signed by the correct factory legal entity.

What should a hardware-specific NNN include beyond the basic three obligations?

For hardware founders, consider including: restrictions on the supplier filing China IP rights (patents, design patents, trademarks) based on the disclosed design; restrictions on sharing product information with subcontractors without approval; a clause confirming that the NNN covers all personnel who access the disclosed information; a clear description of what is disclosed (the disclosure schedule); jurisdiction and venue for disputes (typically a Chinese court, not arbitration, for practical enforceability); and liquidated damages clauses in Chinese yuan that reflect the commercial value of the information.

NNN vs NDA for China Manufacturing: What Hardware Founders Need to Know

Q: Why is a standard NDA not enough for China manufacturing?

A standard NDA (non-disclosure agreement) typically covers only the obligation not to share confidential information with third parties. It does not restrict the supplier from using your design to make the same or similar products for other buyers (non-use), from introducing your customer to the factory directly and bypassing you (non-circumvention), or from filing IP rights based on your design in China. These three gaps — non-use, non-circumvention, and IP filing restriction — are the main reasons an NDA alone is insufficient for China manufacturing.

Q: What is a China NNN agreement?

A China NNN agreement is a three-obligation confidentiality agreement specifically structured for China: non-disclosure (do not share), non-use (do not use to make competing products), and non-circumvention (do not bypass the buyer to deal directly with the buyer's customers or IP). An NNN is designed to be governed by Chinese law and enforceable in China, unlike most foreign-law NDA templates. For hardware founders, the NNN is typically the first agreement to be signed before product files are shared.

A standard NDA covers confidentiality. That is not enough for China manufacturing. Hardware founders need non-use, non-circumvention, tooling terms, and China-side enforceability.

In short

An NDA covers non-disclosure. A China NNN adds non-use and non-circumvention — the two obligations that matter most when a factory can copy your design or route around your customer relationship. For hardware founders, even a well-drafted NNN should be followed by manufacturing and tooling terms before production begins.

What an NDA Covers — and What It Does Not

A non-disclosure agreement (NDA) is designed to prevent the recipient from sharing confidential information with third parties. In a straightforward business context — two companies evaluating a partnership, an employee not disclosing trade secrets — an NDA often serves its purpose adequately.

In China manufacturing, an NDA covers only one of the three main risks hardware founders face:

Disclosure risk (NDA covers this)

The supplier shares your product files, designs, or specifications with a third party — another customer, a subcontractor, a competing buyer. An NDA restricts this.

Use risk (NDA does NOT cover this)

The supplier uses your design to make the same or similar product under a different brand for a different customer — without disclosing to anyone. This is non-disclosure compliant but commercially damaging. A standard NDA does not prohibit it.

Circumvention risk (NDA does NOT cover this)

The supplier contacts your customers, distributors, or retail channels directly, bypassing you. Or introduces your customer to the factory and cuts you out of the supply chain. A standard NDA does not restrict this.

What a China NNN Agreement Adds

A China NNN agreement is structured for three separate obligations — non-disclosure, non-use, and non-circumvention — and is drafted to be governed by Chinese law and enforceable in a Chinese court or through CIETAC/China arbitration.

Non-disclosure

Do not share the disclosed information with third parties. Same as an NDA.

Non-use

Do not use the disclosed information to make similar products, improvements, or competing items for any party other than the disclosing buyer. This directly addresses copycat production by the supplier.

Non-circumvention

Do not bypass the buyer to deal directly with the buyer's customers, distributors, or retail channels. Do not introduce the buyer's customer to the factory without the buyer's consent.

China-law governed

The agreement is drafted to be enforceable in China — where the factory is located, where assets are held, and where any injunction or damages claim would need to be executed. A foreign-law NDA may be practically unenforceable against a Chinese entity with no overseas presence.

Liquidated damages in RMB

A well-drafted China NNN includes a liquidated damages clause specifying a penalty amount in Chinese yuan — removing the need to prove and quantify loss in a Chinese court, which can be difficult and slow.

Hardware-Specific NNN Considerations

Hardware founders face additional IP exposure points that most general NNN templates do not address:

IP filing restrictions

Chinese law does not automatically prevent a supplier from filing a patent or design patent based on a product they received under NNN. A hardware NNN should include an explicit clause prohibiting the supplier from filing any IP rights in China based on the disclosed design, product, or technology.

Subcontractor and sister-factory disclosure

A factory may send your product files to a subcontractor or sister company for quoting or production. Without a clause restricting this, the NNN covers only the entity you signed with. A hardware NNN should require approval before any sub-disclosure and extend liability to the supplier for unauthorized sub-disclosures.

Scope of the disclosure schedule

The NNN should name what is being disclosed — a clear disclosure schedule specifying the product category, file types, and applicable project. This limits disputes about what was actually confidential at the time of disclosure.

When an NNN Alone Is Not Enough

An NNN covers the disclosure phase. Once a hardware relationship moves toward sampling, tooling, and production, additional agreements are needed:

Tooling and mold ownership

An NNN does not address who owns the molds. A tooling payment made without a separate ownership clause defaults to the factory's physical possession — and possession in China often determines who can move or use the mold. A manufacturing agreement or tooling-specific PO clause is required.

Production file and design ownership

Who owns the CAD files created during production? What about design improvements made by the factory during sampling? These questions require manufacturing agreement terms — not NNN terms.

Product quality and specification control

Manufacturing agreements establish quality standards, tolerance specifications, approved-sample benchmarks, and inspection rights. An NNN has nothing to say about product quality.

Exit and return terms

What happens to molds, files, and samples if the relationship ends? A manufacturing agreement addresses return, destruction, and transfer. An NNN may include a return-of-information clause, but it rarely covers tooling.

Frequently Asked Questions

Why is a standard NDA not enough for China manufacturing?

A standard NDA only covers non-disclosure — preventing the supplier from sharing your information with others. It does not restrict the supplier from using your design to make competing products (non-use), or from bypassing you to deal with your customers directly (non-circumvention). Both are common risks in China manufacturing.

What is a China NNN agreement?

A China NNN is a three-obligation agreement: non-disclosure, non-use, and non-circumvention. It is drafted to be governed by Chinese law and enforceable in a Chinese court. For hardware founders, it is typically the first agreement signed before product files are shared with any Chinese manufacturer.

Is a China NNN enough on its own for hardware founders?

An NNN is the right starting point, but it needs to be followed by manufacturing agreement terms covering tooling ownership, production file control, quality standards, and exit terms as the relationship moves toward production. The NNN protects the disclosure phase; a manufacturing agreement protects the production phase.

When should the NNN be signed?

Before any sensitive product information is shared — CAD files, STP files, detailed product specs, BOM, PCB information, firmware notes, or prototype samples. Initial contact (product category, function, approximate volume) can happen first, but anything revealing the design should wait until the NNN is signed by the correct factory legal entity.
