Why a Western NDA Doesn't Work in China (Use an NNN Agreement)
Why a Western NDA Doesn't Work in China (Use an NNN Agreement)
You are about to send your product drawings to a Chinese factory. Your lawyer hands you a clean, two-page US NDA. You sign it, the supplier signs it, and you feel protected. You are not. A Western NDA is close to worthless against a Chinese supplier, because it was built for a jurisdiction that has no power over them. After 20-plus years helping importers protect IP from Yiwu, RND Sourcing insists clients use the instrument Chinese courts actually recognise: the NNN agreement. Here is why the NDA fails and what to put in its place.
Why a US-Style NDA Is Unenforceable in China
An NDA drafted under US law and written in English has three structural problems in China. First, enforcement happens in US courts that have no jurisdiction over a Chinese entity and no easy way to seize assets there. Second, even if you win a US judgment, collecting from a Yiwu factory is a separate, often impossible fight. Third, translating the English contract into Chinese for a Chinese court weakens its terms and exposes gaps. The result: a supplier can violate the NDA with little practical risk, and many do.
Jurisdiction is everything
A contract you cannot enforce is a press release, not protection. Before sharing designs, confirm your counterpart is verified — see our OEM vs ODM and verification guide.
The NNN Agreement: Three Letters That Actually Protect You
The NNN agreement stands for Non-Disclosure, Non-Use, and Non-Circumvention. Where a Western NDA mostly promises silence, the NNN goes further and is the standard Chinese suppliers themselves understand. Each element closes a different door.
- Non-Disclosure: the factory may not reveal your designs, specs, or commercial information
- Non-Use: the factory may not use your IP to make products for itself or others
- Non-Circumvention: the factory may not bypass you to reach your buyers, suppliers, or channels
The 'non-use' and 'non-circumvention' limbs are what make the NNN far stronger than an NDA for importers — they attack the two behaviours (copying your product, and stealing your customers) that an NDA barely touches.
Draft It Under PRC Law and Sign Before Sending Drawings
The NNN must be governed by PRC law, bilingual (English and Chinese with the Chinese version controlling), and signed before any technical drawing leaves your hands. Signing after you have already emailed the CAD files is like locking the barn after the horse is gone — the disclosure you wanted to prevent has already happened. Build the NNN into the first outreach, not the final contract. Chinese courts are far more likely to enforce a clearly drafted, locally governed NNN than any foreign NDA.
Draft under PRC law
Engage counsel familiar with Chinese contract enforcement; state PRC law governs.
Make it bilingual
English + Chinese, with the Chinese text controlling in any dispute.
Define the IP broadly
Cover drawings, specs, samples, tooling, and business relationships.
Sign before disclosure
Get the executed NNN in hand before any CAD, photo, or sample is sent.
Keep the original
Store the signed Chinese original; a scanned copy is weaker evidence.
Combine NNN With Mold Ownership and Exclusivity
The NNN is strongest when wrapped around your other protections. Pair it with the mold-ownership clause (see our mold ownership guide) so the factory cannot keep and reuse your tooling, and with an exclusivity clause so they cannot make your design for others using their own molds. The NNN stops disclosure and circumvention; ownership and exclusivity stop physical reuse. Together they form a near-complete IP fence.
Common Drafting Mistakes That Void the Protection
- Using an English-only US NDA instead of a bilingual PRC NNN
- Signing after the drawings have already been sent
- Vague IP definition that omits samples, tooling, or buyer relationships
- No liquidated-damages or specific-performance remedy
- Letting the supplier's 'standard form' replace your NNN
The supplier's form is not your friend
If a factory insists on using 'our standard confidentiality form,' it is almost certainly weaker than a proper NNN. Hold the line and use your own PRC-governed agreement.
What to Do If a Supplier Refuses to Sign
A supplier that refuses a reasonable, PRC-governed NNN is signalling intent. Either they plan to use your design, or they are not sophisticated enough to be a safe partner for custom work. Treat refusal as a hard red flag: walk away or restrict them to off-the-shelf, non-proprietary products only. The cost of losing one supplier is nothing next to the cost of a copied product in your own market.
Enforcing an NNN: Steps If the Line Is Crossed

If you believe a factory has breached the NNN, move fast and document everything: capture the infringing listings, retain the signed Chinese original, and record the timeline of disclosure. Chinese enforcement is more responsive to a well-documented, locally governed NNN than to a foreign judgment. RND Sourcing has helped clients issue formal notices and coordinate local counsel, and the credible threat of enforcement often stops the breach without litigation.
RND Sourcing's Standard NNN Workflow

In every custom or OEM project, RND Sourcing puts the bilingual, PRC-governed NNN in place before the first drawing moves. We hold the executed Chinese original, verify the counterparty (so we are contracting a real, registered entity), and only then release technical files through a controlled channel. This workflow is why our clients' designs stay theirs — the NNN is signed first, not after the leak.
NNN vs NDA Quick Reference
| Dimension | Western NDA | Chinese NNN |
|---|---|---|
| Governing law | US / foreign | PRC law, bilingual |
| Stops copying your product | Weakly (disclosure only) | Yes, via non-use |
| Stops supplier bypassing you | Usually no | Yes, via non-circumvention |
| Enforceable in China | Rarely | Yes, if properly drafted |
| Sign timing | Often after disclosure | Before any drawing sent |
Conclusion
A Western NDA gives you a false sense of safety and almost no real protection against a Chinese supplier. The NNN agreement — non-disclosure, non-use, non-circumvention — drafted under PRC law, bilingual, and signed before your drawings leave your hands, is the instrument Chinese courts will enforce. Wrap it around your mold-ownership and exclusivity clauses and you have a fence, not a suggestion. To put a proper NNN in place before your next custom order, reach out to RND Sourcing and we will execute it from Yiwu.
Why won't a US NDA protect me against a Chinese factory?
Because it is governed by foreign law and enforceable only in US courts with no jurisdiction over the Chinese entity. Collecting on a US judgment in China is extremely difficult, so the supplier faces little real risk.
What makes an NNN different from an NDA?
An NNN adds non-use (the factory cannot make your product for others) and non-circumvention (it cannot bypass you to reach your buyers), whereas an NDA mostly only promises not to disclose.
When should the NNN be signed?
Before any technical drawing, sample, or specification is sent. Signing afterwards fails to prevent the very disclosure you wanted to control.
Does the NNN replace mold ownership and exclusivity clauses?
No — they complement each other. The NNN stops disclosure and circumvention; the mold-ownership clause stops the factory keeping and reusing your tooling. Use both.
Don't ship your drawings behind a US NDA that a Yiwu factory can ignore. Use a bilingual, PRC-governed NNN — signed before disclosure and wrapped around your mold and exclusivity clauses. Send RND Sourcing your custom project and we will execute the NNN from Yiwu before a single file moves.
