NDA vs NNN Agreement: What Protects You in China
A Western-style NDA only stops a supplier from talking about your product. An NNN agreement also stops them from making it and selling it to your customers. Here is what each one covers, and when each is enough.
An NNN agreement protects your product in China. A standard NDA does not.
That is the short answer for any buyer about to send files to a Chinese factory. A typical non-disclosure agreement only stops the other party from revealing your information. It says nothing about the factory using your drawings to manufacture your product for itself or for someone else.
An NNN agreement (non-disclosure, non-use, non-circumvention) closes that gap. The enforceable versions are bilingual with Chinese controlling, governed by Chinese law, sealed with the factory's official company chop, and carry a fixed penalty for every breach.
Sorting this out before any technical file changes hands is standard practice for a competent sourcing partner. CN Ally verifies each supplier's legal identity and makes sure a signed NNN is in place before drawings are shared.
Why a standard Western NDA falls apart in China
A US- or UK-drafted NDA fails in China on three independent counts, and any one of them is enough to make the document decorative.
Wrong court. Most imported templates name a foreign court as the dispute forum. Chinese courts generally do not enforce foreign judgments in intellectual property disputes; a foreign judgment must go through a separate recognition proceeding that is frequently denied. A clause that says "disputes will be resolved in California" is, for practical purposes, a permission slip.
Wrong language. Chinese courts work in Chinese. An English-only contract creates an interpretation problem the moment a dispute starts, because the factory's chop applies to Chinese text and judges read Chinese. An English-only NDA is at best half-enforceable and at worst read as ambiguous. Bilingual contracts are fine, but the agreement must state that the Chinese version prevails.
Wrong scope. This is the fatal one. A typical NDA prohibits disclosure, not use. If the factory manufactures your design for its own product line, it has not disclosed anything, and nothing in a disclosure-only agreement was violated. The copying most buyers fear lives in this gap: the factory never tells anyone, it just starts making.
The gap matters even with honest suppliers. A factory owner may see your design, decide it would sell well, and hand it to a sister company or a cousin's workshop. From their perspective, nothing confidential was "revealed." From yours, your product is now on the market at half your price.
What the NNN adds: non-use and non-circumvention
An NNN agreement contains three sets of obligations, and the last two are the ones an NDA lacks.
Non-disclosure works like an NDA: the factory may not share your drawings, specifications, customer lists, or pricing with outsiders.
Non-use is the clause that stops the factory from producing your design for any purpose other than fulfilling your order. It may not make your product for itself, for a competitor, or under a different brand. This obligation can cover even concepts and ideas that do not qualify as formal intellectual property, which is why it reaches further than a patent or a copyright filing alone.
Non-circumvention stops the factory from bypassing you to sell directly to your customers, distributors, or end buyers. Without this clause, a supplier that ships your product to your own customer can claim it was simply answering an inquiry. The clause should name your customer categories and survive the end of the agreement.
Two related protections often ride along in the same document. A non-competition clause can restrict the factory from selling competing products in your market for a defined period, though these are narrower and harder to enforce than the core three. And the obligations should expressly extend to the factory's affiliates and subcontractors, so the design cannot legally leak through a related company or an outsourced production line.
An NNN is usually signed early, before drawings, tech packs, or tooling payments move. Note its limit: it is not a manufacturing agreement. It does not set prices, specifications, or delivery terms. Those belong in a separate product development or supply agreement, signed alongside it.

Five requirements that make an NNN enforceable
The enforceability of an NNN does not come from the word "NNN" in the title. It comes from five technical requirements. Miss any of them and the document is decoration.
1. The Chinese text controls. Bilingual contracts are common and practical. But the agreement must state explicitly that the Chinese version prevails in case of conflict. Chinese courts will read the Chinese either way.
2. Chinese law, Chinese forum. Name the laws of the People's Republic of China as the governing law and specify a Chinese court, ideally in the supplier's province, or an arbitration body. Chinese courts can act directly against the manufacturer's assets: freezing accounts, seizing goods, enforcing injunctions. Foreign remedies cannot do any of that without recognition proceedings.
3. The correct legal entity. The name on the agreement must match the factory's registered legal name exactly. A trading company middleman and the actual manufacturer are different legal entities, and an agreement signed by the wrong one binds no one. Ask for a copy of the business license and check the name against the National Enterprise Credit Information Publicity System before the agreement is sealed.
4. The company chop, not just a signature. The official seal is what binds a Chinese company to a contract. Verify that the name on the chop matches the name on the business license.
5. Liquidated damages in a stated amount. A fixed penalty per breach, so you never have to prove the exact financial damage of IP misuse. This clause does most of the real work, and it deserves its own section.
The company chop: why a signature is not enough
In China, the round red company seal carries the authority that a signature carries in the West. A contract sealed with the official chop binds the company; a signature from a sales representative on WeChat may bind nobody if that person lacks signing authority.
The practical check is simple: the legal name on the agreement, the name on the business license, and the name on the chop must all match. Before any factory seals an NNN, confirm the company exists, holds an active registration, and has manufacturing in its licensed business scope rather than trading. An on-site factory audit verifies the entity you are actually contracting with, including who operates the floor you will pay for tooling at.
This is also where middlemen create risk. If your agreement is sealed by a trading company but your drawings go to a separate factory, the factory that can actually copy you is not bound. When two entities are involved, both should sign.
Liquidated damages: the clause that does the heavy lifting
Under the PRC Civil Code (Articles 585–588), proving actual damages from IP misuse is extremely difficult. The burden of proving the exact financial loss falls on the injured party, and the damage from a factory quietly manufacturing your design is close to impossible to quantify precisely.
A liquidated damages clause solves this by setting the penalty in advance. The supplier knows the exact cost of a breach before signing, which deters the breach. If a breach happens anyway, you do not have to reconstruct your losses; the amount is already in the contract. A demand letter citing a specific, pre-agreed figure carries far more weight than a vague threat to sue.
One qualification: Chinese courts can reduce liquidated damages that are clearly disproportionate to the actual loss. Penalties are treated as compensatory, not purely punitive. Draft the figure to be reasonable but meaningful: tie it to the value of the project, state it as a per-breach amount, and add that the breaching party covers any losses beyond the fixed amount. The enforceability guide from GBA IP Lawyer walks through this structure in detail.
When an NDA is enough
Not every relationship needs an NNN. A simple NDA is sufficient when no manufacturing is involved and no production information changes hands: early discussions with a market research consultant, a marketing agency, a financial advisor, or a logistics partner who will never hold your CAD files.
The test is straightforward. If the other party will never have your drawings, your tooling, or access to your production process, an NDA covers what needs covering. The moment samples, molds, or production drawings enter the picture, it stops being sufficient.
When you need an NNN
Any manufacturing relationship that involves your intellectual property calls for an NNN, signed before the first file goes:
- sending drawings, CAD files, or tech packs to a factory
- paying for molds, tooling, or development work
- OEM or ODM production of your own design
- sharing customer lists, pricing, or supplier information with a manufacturer
- factory visits where your product is visible on the floor
Get it signed at the quoting stage, before commercial momentum makes anyone reluctant to introduce paperwork. A document presented after the drawings are already sent protects nothing.
How to get one signed in practice
Keep the agreement short enough that a factory owner signs it without retaining counsel of their own. Present it in bilingual form, Chinese controlling. Introduce it as a standard step every buyer takes, because it is.
A sourcing partner earns its keep here: verifying the business license, confirming the chop name matches the legal entity, and making sure the document is sealed before drawings move. Ongoing quality control presence at the factory then reinforces the agreement, because a factory that knows an independent inspector walks the floor treats contractual obligations more seriously.
If a factory refuses to sign outright, treat the refusal as information. Legitimate manufacturers sign confidentiality documents routinely; a supplier that will not agree in writing not to copy you is telling you something about its intentions. Either walk away or limit what you share to what you can afford to lose.
One more practical discipline: disclose in stages. Share a high-level product description and photos while you compare quotes, and release detailed CAD files and technical drawings only after the NNN is signed and sealed. Staged disclosure costs nothing and shrinks the window in which anything can leak.
What an NNN cannot do
An NNN is a strong tool with clear limits. Understand them before relying on it.
It is not a substitute for registering your IP in China. China runs a first-to-file trademark system: whoever registers your brand name first owns it in China, regardless of what your contract says. File your trademark before sharing files. An NNN is a contract with one factory; a registration is a property right enforceable against everyone.
It does not set commercial terms. Prices, specifications, tolerances, and delivery schedules need their own manufacturing agreement. As AEON Law's NNN guide puts it, an NNN provides a level of protection but does not spell out the terms of the business relationship.
It protects secrets you keep secret. Information you publish freely, post on social media, or disclose without marking it confidential is no longer confidential information, whatever the contract says.
Enforcement costs time and money. The agreement's greatest value is deterrence and leverage, which is why the liquidated damages clause matters so much. A factory that faces a specific, enforceable penalty usually chooses not to become a test case.
Frequently asked questions
Can I just translate my English NDA into Chinese?
No. Translation fixes the language problem but not the scope or jurisdiction problems. A Chinese-language NDA still permits the factory to use your design and bypass you to your customers unless you add non-use and non-circumvention clauses. Once you add those clauses, governed by Chinese law, you have written an NNN by another name.
Can I use a free template instead of hiring a lawyer?
A China-specific template beats an imported US template every time. But templates are generic, and the clauses that matter most are the specific ones: the definition of confidential information should match what you actually share, the per-breach damages should match your project value, and the non-circumvention clause should name your actual customer categories. Vague clauses are the ones courts struggle to enforce.
The factory or the trading company: whose name goes on it?
The legal entity that will receive and use your intellectual property. If a trading company handles your order but a separate factory manufactures, both should sign, and each name must be verified against its own business license. An agreement sealed by an entity that never touches your drawings binds the wrong company.
What if the factory refuses to sign?
Either walk away or sharply limit what you share. Outright refusal is rare among legitimate manufacturers, who sign confidentiality documents as a matter of routine. Treat a refusal as a signal about the supplier's intentions rather than a paperwork dispute.
Do I still need to register my trademark in China?
Yes. The NNN binds one factory; a trademark registration is a property right enforceable against anyone, including the factory's competitors and copycats you have never met. File the registration before any design files go out, not after the first shipment lands.
Should the NNN cover the factory's subcontractors?
It should. Factories routinely outsource plating, printing, or assembly to smaller workshops, and your drawings travel with the work. The agreement should state that its obligations extend to affiliates, subcontractors, and any third party the factory shares your information with. Without that extension, the factory can comply with the letter of the agreement while your design leaks through its supply chain.
The rule before any drawing leaves your computer
No CAD file, tech pack, sample payment, or mold deposit goes out without three things in place: an NNN in bilingual form with Chinese controlling, governed by Chinese law, sealed with the chop of the verified legal entity. If you cannot verify the entity, the agreement is decoration.
That single rule, applied consistently, prevents the most common and most expensive IP mistake buyers make in China. For help verifying suppliers and getting protective agreements signed before drawings move, reach out at hi@cnally.com.
