Every week a foreign company sends its standard NDA to a Chinese factory, gets a signature in minutes, and concludes the relationship is protected. The fast signature should be the warning: the factory knows the document is close to unenforceable against it.
Three reasons the standard NDA fails
- It prohibits the wrong thing. NDAs stop disclosure. The dominant China risk is not your factory leaking secrets to others — it is the factory using your designs itself, or circumventing you to sell directly to your customers. Neither is "disclosure".
- It's governed by the wrong law. An NDA under New York law with New York courts produces, at best, a judgment Chinese courts will generally not enforce. Your factory's assets are in Dongguan, not Manhattan.
- Damages are unprovable. Even in the right forum, proving the quantum of trade-secret damages under common-law principles is slow and speculative.
What an NNN agreement does instead
A China-appropriate NNN agreement is built backwards from enforcement:
- Non-use — the counterparty may not use your information, designs, tooling or specifications for any purpose beyond your orders, including "improvements" and derivative products.
- Non-disclosure — covering affiliates, subcontractors and employees, with the counterparty liable for their breaches.
- Non-circumvention — no direct or indirect sales to your customers or channel, identified by category rather than a static list.
- Chinese law, Chinese forum — governed by PRC law with jurisdiction in the defendant's local court or a Chinese arbitration commission, so remedies hit assets directly.
- Liquidated damages — a fixed, per-breach amount large enough to deter but calibrated so a Chinese court will uphold rather than reduce it. This converts an unprovable damages case into a debt claim — and supports asset freezing.
Practical notes
Sign the NNN before the first email with drawings, not at PO stage. Verify the legal name and have it chopped with the registered company seal. And put the NNN obligation into every downstream document — your purchase orders and tooling agreements should reference it.
A two-page NNN drafted properly is worth more in China than twenty pages of imported boilerplate.
