China NNN Agreement: Non-Disclosure, Non-Use, and Non-Circumvention Explained (2026)

When a foreign company outsources manufacturing to a Chinese factory, its most valuable assets — product designs, moulds, tooling files, firmware, formulas, and customer lists — are suddenly placed in someone else’s hands. A handshake is not enough, and a standard Western non-disclosure agreement is usually not enough either, because Chinese law and the remedies available on the ground work differently. That is precisely why the NNN agreement was created. This guide explains what a China NNN agreement is, how its three core clauses protect you, and how foreign buyers sourcing from Guangzhou, Shenzhen, Dongguan, and Foshan can use one to safeguard their intellectual property before, during, and after production.

What Is an NNN Agreement in China?

The NNN agreement takes its name from three promises the supplier makes: non-disclosure, non-use, and non-circumvention. It is a China-specific contract drafted under PRC law, executed in both Chinese and English, and designed to be enforceable in a Chinese court or arbitration body. Unlike a generic NDA, which only prevents disclosure of confidential information, an NNN agreement goes further by prohibiting the factory from actually using your intellectual property and from dealing directly with your customers or partners behind your back.

An NNN agreement is most commonly used in manufacturing and sourcing relationships. If you contract a factory in Dongguan to produce a custom-designed consumer product, or a supplier in Shenzhen to assemble electronics using your firmware and schematics, the NNN agreement is the document that gives those assets legal protection on the ground in China. It can cover designs, drawings, specifications, moulds and tooling, software, formulas, price lists, customer data, and any other confidential business information you share during the relationship.

Why an NNN Agreement Matters When Sourcing in Shenzhen, Dongguan, and Foshan

Guangdong province is China’s manufacturing heartland. Shenzhen is the global hub for electronics and hardware, Dongguan and Foshan are centres for injection moulding, furniture, and household goods, and Guangzhou serves as the region’s trade and logistics gateway. For a foreign company, the concentration of capable suppliers in these cities is a huge advantage — but it also concentrates risk.

The practical reality is that many factories in the region work with multiple overseas clients in the same product category. Without a binding contract, a factory that produces your product for one season may quietly produce a near-identical version for a competitor the next season, or use your tooling to fulfil other orders. Chinese law is a contract-driven and first-to-file system: whatever protection you want, you generally have to secure it in writing before the work begins. An NNN agreement creates that written foundation and gives you a clear legal path to damages and injunctions if the factory breaches its obligations.

The Three Core Clauses, Explained

Non-disclosure. The supplier agrees to keep confidential all information you share — technical, commercial, or financial — and not to reveal it to any third party. This includes product designs, CAD files, cost structures, and customer information. The clause should list exactly what counts as confidential so there is no ambiguity later.

Non-use. This is the clause that sets an NNN agreement apart from a simple NDA. The supplier promises not to use your confidential information or intellectual property for any purpose other than fulfilling your order. In practice, this means the factory cannot use your moulds to make products for another buyer, cannot replicate your design for its own brand, and cannot apply your specifications to any project other than yours.

Non-circumvention. The supplier agrees not to bypass you to deal directly with your customers, your distributors, or your other suppliers. This prevents the factory from contacting your end customers, learning your pricing, and then cutting you out of the supply chain. It also stops the factory from quietly shifting your orders to a sub-supplier in a way that sidesteps your control.

Key Terms to Negotiate Before You Sign

Governing law and jurisdiction. Specify that PRC law governs and that disputes will be resolved in a Chinese court or a recognised arbitration body such as CIETAC or the Shenzhen Court of International Arbitration. Choosing local jurisdiction makes any eventual award far easier to enforce inside China.

Liquidated damages. Chinese courts are generally more willing to enforce liquidated damages clauses than courts in some other jurisdictions. A clearly stated penalty per breach — for example, a fixed sum or a multiple of the contract value — gives you leverage and a realistic recovery path.

Scope and duration. Define the information covered and set a realistic term. Confidentiality obligations should survive the end of the agreement, while non-circumvention obligations should last for a defined period after the contract concludes.

Audit and inspection rights. Reserve the right to inspect the factory and audit its records so you can verify the supplier is not running an unauthorised production line for someone else using your tooling.

Bilingual execution. An NNN agreement should be executed in both Chinese and English, with the Chinese version controlling for enforcement purposes. A court in China will work from the Chinese text, so the accuracy of the translation matters.

How to Enforce an NNN Agreement in China

The value of an NNN agreement is only as strong as your ability to enforce it. In practice, enforcement usually combines evidence gathering with legal action. If you suspect a breach, the first step is to document it: collect product samples, photographs, purchase orders, and communications that show the factory is using your intellectual property or dealing with your customers.

From there, you can pursue a civil claim in a Chinese court seeking an injunction and damages, or file for arbitration if your agreement so provides. You can also report the infringement to the local market supervision authority, which in cities such as Guangzhou and Shenzhen has the power to investigate and seize infringing goods. Finally, customs recordation can stop infringing exports at the border.

A common misconception is that an NNN agreement guarantees compliance. It does not. What it does is transform a messy, hard-to-prove situation into a clear contractual breach with defined remedies. Factories take contracts seriously when they know the buyer has local counsel ready to act.

Common Mistakes Foreign Buyers Make

Using a Western NDA. A template NDA written for US or European law often lacks the non-use and non-circumvention protections, and may contain jurisdiction clauses that are effectively meaningless in China.

Signing with the wrong party. Make sure the agreement is signed by the legal entity that will actually manufacture, not a trading intermediary. In Foshan and Dongguan, buyers frequently discover that the factory that produced the goods was never the entity named on paper.

Sharing too much too early. Only disclose what the factory needs for the specific order. Share moulds, firmware, and full drawings only after the NNN agreement is signed, not during early price negotiations.

No damages clause. An NNN agreement without a clear liquidated damages provision is far harder to enforce and gives you little leverage when something goes wrong.
