NNN vs NDA in China: The Agreement That Actually Protects Your Design
You are about to send your drawings to a factory you have never met. The NDA your US lawyer wrote will not save you here. Let me show you what does, in plain words, before you hit send.
Do you need an NNN or an NDA for a Chinese manufacturer?
An NDA only stops disclosure, and it is usually written for a US or European court a Chinese factory will never appear in. An NNN — Non-Disclosure, Non-Use, Non-Circumvention — also stops the factory from using your design or selling around you, written in Chinese under Chinese law so it is enforceable where the factory actually is. For China, you want the NNN.
Why your US NDA usually fails in China
I have stood on these floors for twenty-five years, and I will tell you the truth: the NDA you signed at home is built for the wrong country. A standard US NDA does one thing. It says the other side must keep your secret. That is all it guards.
That is not your real risk in China. Your real risk is not that the factory tells your secret to a stranger. Your real risk is that the factory keeps your design, makes the same product under its own name, and sells it to your own customers at a lower price. Your NDA says nothing about that. It never promised the factory would not compete with you. It never promised the factory would not go around you.
There is a second problem, and it is bigger. Your NDA is written in English, it points to a court in your home state, and it says your home law rules. A Chinese factory does not have money in your state. A judgment from your court is very hard to collect against a company that only exists in China. So even when you are right, you win a piece of paper you cannot cash. The factory knows this. That is why the NDA does not scare anyone here.
What an NNN is, and why it works where the NDA does not
NNN stands for three promises: Non-Disclosure, Non-Use, and Non-Circumvention. It was built by China lawyers for exactly this problem.
Non-Disclosure is the old promise: do not tell my secret. Non-Use is the promise your NDA forgot: do not make my product for yourself or for anyone else, even a version with small changes. Non-Circumvention is the third: do not go around me to reach my customers or my suppliers. These last two are what actually protect a buyer who is sending a design to a factory. They stop the factory from becoming your competitor with your own drawings.
An NNN works because it is written to fit the Chinese system, not fight it. It is governed by Chinese law. It names a Chinese court that has real power over the factory, or a Chinese arbitration body. And it is written in Chinese as the version that rules. That means if the factory breaks its word, you sue where the factory actually has bank accounts and machines, in the language the judge reads, under the law the judge applies. That is a case a factory has to take seriously.
Side-by-side: NDA vs NNN
What each one covers — NDA: only secrecy, do not tell my secret to others. / NNN: three things at once — do not tell my secret (Non-Disclosure), do not make or use my product for yourself (Non-Use), and do not go around me to my customers or suppliers (Non-Circumvention).
Stops the factory from copying and competing — NDA: no, it never promised this. / NNN: yes, this is the whole point of the Non-Use promise.
Enforceability inside China — NDA: weak, usually points to a foreign court and foreign law, so a Chinese factory can ignore it. / NNN: strong when governed by PRC law and heard in a Chinese court or Chinese arbitration that has real power over the factory.
Governing language — NDA: usually English only, which a Chinese court must translate and may read differently than you meant. / NNN: Chinese is the ruling version, so the judge reads exactly what you agreed.
Where you enforce it — NDA: a foreign court, where the factory has no assets you can reach. / NNN: a Chinese court where the factory has bank accounts and equipment that can actually be frozen or seized.
When to use each — NDA: fine between two US companies under US law, or for early talk that shares no product design. / NNN: whenever you send drawings, samples, molds, specs, or a working design to a Chinese factory. This is the one you want before any file leaves your hands.
A note on the June 2026 trade secret rules, honestly
You may have read that China passed strong new trade secret rules. That is true. China's State Administration for Market Regulation issued new Provisions on the Protection of Trade Secrets on February 24, 2026, and they took effect on June 1, 2026, replacing rules that had stood since 1995. They add a government enforcement route with injunctions and fines up to five million RMB.
Here is the honest part. Those rules are a public enforcement tool. They punish the wrongdoer with a government fine. They do not pay you your losses, and they only bite when the information counts as a protected trade secret. Your design shared with a factory does not always meet that bar. The new rules are a good thing, and they raise the cost of stealing, but they do not replace a private contract between you and your factory. The NNN is still the thing that binds your specific factory to specific promises and lets you collect when it breaks them. One is the police. The other is your own signed agreement. You want both.
Where I stand in this
I am not the factory's man. Only you pay me, so my only job is to protect you. When you send me to the floor, I find out who really makes your product, I check that the bank account name matches the real company before you wire a single dollar, and I give you a full written report — go or no go, every red flag, every document, my honest notes. Every word is backed by something I saw or a paper I held.
The NNN is the same idea in a contract. It is built to the standard China lawyers use, so the promise on the paper is a promise you can actually enforce. Get it signed in Chinese, governed by Chinese law, before your drawings leave your hands. Do not send the file first and paper it later. By then the factory already has everything.
Do not send your design on a handshake and an English NDA. Get the China NNN Agreement (/china-nnn-agreement) — built to the standard China lawyers use, in Chinese, governed by PRC law — and sign it before your files leave your hands. Want the full set for the whole deal, from NNN to purchase terms to quality inspection? Get the Contracts Vault (/china-contracts-vault). And if you want me to look at your specific factory and your specific risk before you wire a dime, book a call. Attorney-drafted NNNs run $800 to $2,500; get protected today for a fraction of that, then bring in PRC or Hong Kong counsel if your IP is high-value.

Is an NNN agreement legal advice, or a template?
What I hand you is a professional template built to the standard China lawyers use, not legal advice for your exact case. It covers the common situation well. For high-value or complex IP — a patent, a proprietary process, a large order — have qualified PRC or Hong Kong counsel review it before you sign. The template gets most buyers protected; counsel is for when the stakes are high enough to warrant it.
Why does the agreement have to be in Chinese?
Because a Chinese court reads Chinese. If your only version is English, the court works from a translation, and the meaning can shift away from what you intended. When the Chinese version is the one that rules, the judge reads exactly what you and the factory agreed. That is why an NNN names Chinese as the governing language. It is not a formality; it decides how your case is read.
My factory says an NDA is enough. What do I say back?
A factory that only wants an NDA is telling you something. An NDA guards secrecy and stops there. It does not promise the factory will refuse to make your product for itself or sell around you to your customers. Ask instead for an NNN with Non-Use and Non-Circumvention, governed by Chinese law, heard in a Chinese court. A serious factory that plans to keep its word signs it. Resistance to those two promises is a red flag worth noticing.
Doesn't the new June 2026 trade secret law already protect me?
It helps, but it does not replace your contract. China's new trade secret Provisions took effect June 1, 2026 and add government fines up to five million RMB. That is public enforcement, and it only applies when your information qualifies as a protected trade secret. It does not pay you your losses, and a design shared with a factory does not always meet that bar. The NNN binds your specific factory to specific promises and lets you collect when it breaks them. Use both.
What does a proper China NNN cost?
Honestly, an NNN drafted from scratch by a qualified China IP attorney usually runs $800 to $2,500, depending on complexity. A well-built template covers the common sourcing situation for far less and gets you protected before you send a file. For high-value IP, pay for counsel review on top. Either way, the cost is small next to losing your whole product to a factory that copied it.
When do I need to have the NNN signed?
Before any drawing, sample, mold, spec, or working design leaves your hands. Not after the first sample arrives. Not once you place the order. The moment the factory has your files, it has everything, and a contract signed afterward is far weaker footing. Sign first, share second. That order is the whole protection.
