You sent drawings for a quote. The quote never came; the product did — under the factory's own brand, or worse, your customer under their invoice. If the only thing you signed was a US-style NDA governed by New York law, my honest answer is: in a Chinese courtroom, it is close to paper. Here is what an NNN does differently, and how to draft one that works where your supplier actually is.
Buyers show me two documents more than any others: the NDA they signed with a supplier years ago, and the competitor's product they found on Alibaba last month that looks exactly like theirs. The gap between those two documents is the subject of this guide.
The sequence is always the same. You have a design worth protecting — a product, a mold, a customer list, a pricing structure. To get quotes you send technical drawings to three factories. One of them goes quiet: no quote, no follow-up, deal dead. Eighteen months later your product appears — same dimensions, same drawing errors, sometimes literally the same file names — under the factory's own brand on a trade platform, or in a catalog your own customer forwards to you, asking why the price is different this time.
You look for the NDA. It exists: two pages, signed, serious-looking. It is governed by New York law, disputes to the courts of Delaware. Now ask the practical question: how does that document help you in China? To use it you would need to sue in the US, win, and then ask a Chinese court to recognize that judgment against a Chinese factory — a recognition process that is slow, uncertain, and depends on treaties and reciprocity. Or you would sue in China under New York law, forcing a Chinese court to apply foreign substantive law to a factory's conduct. Both paths cost more than most stolen designs are worth. The document was signed. It was never enforceable where it mattered. That is the disaster — not the leak, but the worthless remedy.
“NNN” stands for non-disclosure, non-use, non-circumvention. The three legs are not synonyms; each one blocks a different way your position leaks:
A US-style NDA protects against one leak — disclosure of information. Chinese supply relationships leak through all three. If your agreement names only the first, you have no contract language at all against the other two, whatever law it is governed by.
An NNN is not free-floating magic; it hooks into two bodies of Chinese law that give it teeth.
Trade-secret protection. Article 9 of the PRC Anti-Unfair Competition Law protects business information that is (a) not publicly known, (b) has commercial value from that secrecy, and (c) is subject to reasonable confidentiality measures. Read condition (c) again, because it is the one buyers lose on: the court asks what you did to protect the information. Marked drawings, restricted file access, staged disclosure, and — centrally — signed confidentiality obligations. Your NNN agreement is not just a promise; it is your evidence that confidentiality measures existed. No measures, no trade secret; no trade secret, no claim — regardless of what the factory did with your files.
Pre-contract confidentiality. Article 501 of the PRC Civil Code imposes a duty on parties to a negotiation: information learned in the course of contracting must not be disclosed to others or improperly used — regardless of whether the contract is eventually formed. That last clause is written for exactly the quote-stage scenario: the factory that received your drawings, never signed anything, and never became your supplier. The statutory duty exists; what the NNN does is define what the information was, prove you treated it as confidential, and price the breach in advance.
This is the part US-style NDAs get wrong, and it matters more than any clause:
The governing-law question also has an answer that surprises buyers: for a relationship that will be fought out in China, Chinese law is not a concession — it is the point. You are choosing the law of the place where the assets, the factory and the enforcement are. Choosing Chinese law and a Chinese forum is what converts the NNN from a statement of principles into a collection instrument.
What separates a real NNN from a template with three N's:
| Clause | What it must say |
|---|---|
| Definition of protected information | Concrete, not eloquent: drawings by file number, mold files, the customer list attached as a schedule, pricing structures, specifications. “All confidential information as generally understood” is how trade-secret claims die — the court needs to know exactly what leaked. |
| Liquidated damages | A fixed amount per act of breach, not one total cap for all breaches — each diverted order or each unauthorized use triggers it. Sized to change the factory's arithmetic: the breach should cost more than one order's profit. Adjustability by the court exists, but a sane, stated number anchors the negotiation and the award. |
| Carve-outs | Information already public, independently developed, or lawfully received from a third party — kept narrow and factual. Overbroad carve-outs (e.g. anything the factory “already knew”, undefined) swallow the whole agreement. |
| Return / destruction | On written demand, within a fixed number of days, with written confirmation of destruction — including copies on shop-floor computers and in CAM files. This clause is what makes post-relationship cleanup enforceable. |
| Non-circumvention scope | Named customers (schedule), named channels (marketplaces, platforms, trade shows), and a defined duration. A non-circumvention clause without a customer list is an invitation to argue about who “your customer” even was. |
| Law & forum | PRC governing law; Chinese arbitration commission named precisely (CIETAC or otherwise); bilingual text with a language-hierarchy clause. On the bilingual point, see the guide to language traps in bilingual contracts. |
One drafting note that saves arguments later: the non-use leg should expressly cover tooling and files — not just “information.” A mold is both physical property and information; your NNN handles the information half and the tooling agreement handles the physical half.
That physical half deserves its own warning, because it is where non-use fails in practice. An NNN, however perfect, does not stop a factory from running your mold at night if the mold sits in their workshop and nobody is sure who owns it. Tooling ownership is the physical twin of NNN protection: a written tooling agreement saying the mold was paid for by you, belongs to you, is tagged and separable, and must be released on demand. The two documents work as a pair — the NNN stops the design from leaking, the tooling terms stop the object from being used. How to structure tooling ownership.
And one adjacent leak that no NNN touches: the brand itself. If your supplier registers your trademark in China while the relationship is good, you may find your own brand blocks your own imports — that is a registration race, not a confidentiality problem. The trademark squatting problem.
Honest section. When an NNN is breached, proving it is work — different work for each leg:
Litigation as a deterrent works when the damages number is real and the forum is local; litigation as a recovery strategy against a factory that already pocketed the profit from your designs is a slower, harder fight. So the honest economics: an NNN drafted properly costs a fraction of one diverted order. It changes behavior mostly by existing — a factory deciding whether to reuse your mold knows which suppliers have signed, executable Chinese-law agreements with per-breach damages and which have a Delaware NDA they have never read. That calculation, not the courtroom, is where most protection happens.
Two complements worth adopting: pick counterparties who don't need to steal — verification before disclosure is cheaper than enforcement after it, the full method here — and if your China relationship is a distribution arrangement, fold the non-circumvention leg into a proper distribution agreement rather than a standalone letter. Distribution agreements in China.

Before the files go out, have the NNN checked — or drafted — against Chinese law and Chinese enforcement: defined information, per-breach damages, local forum. One review now is cheaper than tracing your own product on a trade platform later.
