An NNN agreement in China is a contract that tries to stop three things: disclosure, use, and circumvention. It is broader than a standard NDA and is especially important before you share product designs, samples, molds, drawings, customer information, pricing, or platform plans with a Chinese supplier.
Foreign buyers often ask for an NDA. In China sourcing, that may be too narrow. China-focused contract commentary, including Harris Sliwoski’s China NNN materials, treats NNN agreements as a separate tool because the bigger risk is not only that the supplier tells someone else your idea. The bigger risk is that the supplier uses the information to make the product, sell it, register related IP, approach your customer, or bypass you.
The short definition
NNN means:
- Non-disclosure: do not reveal the protected information.
- Non-use: do not use the protected information for your own production, sale, registration, or competition.
- Non-circumvention: do not bypass the buyer to reach customers, distributors, platforms, factories, or other business relationships.
That third part is where many foreign templates are weak. A supplier may not “disclose” your design in the narrow sense. It may simply manufacture a competing version, contact your distributor, or sell through a different brand.
Why a normal NDA may not be enough
Many Western NDAs are built for information secrecy. They assume the main harm is leaking confidential information to outsiders. That is a real risk, but it is not the only risk in China manufacturing.
If a supplier receives your drawings and then uses them to make the same product for itself, the problem is use. If it contacts your Amazon seller, distributor, or end customer directly, the problem is circumvention. If it passes the files to an affiliated factory and says the affiliate is not bound, the problem is scope.
A China-focused NNN agreement should be written around those practical risks.
When to use it
Use an NNN agreement before sharing:
- product drawings, CAD files, formulas, molds, or samples;
- packaging, branding, artwork, or platform strategy;
- customer lists, distributor names, or end-user information;
- pricing structure, supplier shortlist, or margin information;
- technical know-how not yet protected by registration.
It should be signed before disclosure, not after. Once the supplier has your information, the agreement becomes much harder to negotiate and much less useful as a deterrent.
What it should include
A China NNN agreement should identify the Chinese legal entity by its registered Chinese name. It should be signed or chopped by that entity. The English trade name on a website is not enough.
The agreement should define protected information clearly. It should cover documents, samples, oral disclosures, electronic files, chats, drawings, prototypes, customer names, pricing, tooling information, and any information derived from those materials.
It should also bind people who may actually receive the information: employees, affiliates, subcontractors, factories, related entities, engineers, sample makers, and sales staff. This is not always easy, but the issue should be addressed directly.
The agreement should include a realistic dispute-resolution clause. If the supplier and its assets are in China, a distant foreign court clause may look weak. Depending on the case, Chinese law, Chinese-language drafting, a Chinese arbitration clause, a Hong Kong arbitration clause, or another enforceable route may be more practical.
Finally, it should include a liquidated damages clause. Not because it guarantees the exact amount, but because it makes the breach concrete and gives the demand letter or arbitration claim a clearer number.
Common mistakes
The first mistake is signing with the wrong party. If the NNN is signed by a Hong Kong trading company but the Mainland factory receives the files, the buyer may have a gap.
The second mistake is using an English-only NDA written for a foreign legal system. It may be better than nothing, but it may not create the pressure you expect in China.
The third mistake is treating the NNN as a substitute for IP registration. China is first-to-file for trademarks and has its own design patent and copyright routes. If the design or brand matters, do not rely only on contract promises.
The fourth mistake is waiting until the relationship feels serious. By that point, the supplier may already have the information it needs.
How it connects to disputes
When a supplier copies a product, refuses to return molds, sells to your customer, or uses your design on another platform, the NNN agreement becomes the first document I look for. It can support a demand letter, evidence review, negotiation, arbitration, or litigation strategy.
But only if it was signed properly and before the disclosure.
The bottom line
A China NNN agreement is not a ceremonial NDA. It is a front-end risk control tool. Its job is to make the supplier understand that it cannot disclose your information, use it for itself, or bypass you commercially.
