NNN Agreement

Definition and Scope

An NNN agreement — short for Non-Disclosure, Non-Use, Non-Circumvention — is a contract used when sharing proprietary information with a China-based counterparty, typically a manufacturer or supplier^[1]. It is built specifically to address a risk pattern common in Chinese manufacturing relationships that a standard Western-style NDA was never designed to cover: the risk is not that a supplier leaks a buyer's information to the public, but that the supplier uses that information to produce a competing version of the product, or uses relationships formed during the collaboration to sell directly to the buyer's own customers. NNN agreements have become a standard first step before sharing product designs, specifications, or customer information with an OEM in China^[2].

Why a Standard NDA Falls Short

A conventional NDA is built around a single obligation: don't disclose. That framing works well in contexts where the primary risk is public leakage of trade secrets, but it leaves two other risks completely unaddressed — a counterparty using the information for their own benefit, and a counterparty using the relationship itself to bypass the original buyer^[2][3]. In a typical China manufacturing scenario, an NDA might successfully stop a factory from publishing a client's design online, while doing nothing to stop that same factory from quietly producing and selling an identical product, or approaching the client's own customer list once it has learned who they are^[4]. This is why NNN agreements have become the standard tool for these relationships rather than the NDA templates commonly used elsewhere.

NDA vs. NNN Agreement

What Each "N" Actually Covers

Non-Disclosure prohibits the supplier from sharing the buyer's confidential information — designs, specifications, business plans, or customer data — with any third party^[4]. Non-Use goes a step further and prohibits the supplier from using that same information for its own benefit, such as manufacturing and selling a near-identical product once it has learned how to make it. Non-Circumvention addresses a distinct risk: it prevents the supplier from bypassing the buyer entirely to deal directly with the buyer's customers or upstream suppliers once those relationships become visible through the collaboration. This third clause is the one most frequently missing from general-purpose NDA templates, and it is often the risk that causes the most damage in practice, since a supplier that has both the product know-how and a direct line to the customer has little reason to keep working through the original buyer.

Enforceability Considerations

Being legally recognized and being reliably enforceable are not the same thing. An NNN agreement drafted for enforceability in China is generally localized to PRC law and procedure, often prepared bilingually in English and Chinese, and typically drafted unilaterally in favor of the disclosing party, since it is usually only the buyer's information being protected^[5]. In China, this framework connects to statutory protection under the PRC Anti-Unfair Competition Law, which addresses trade secret protection and unfair competition more broadly^[6]. Even with a well-drafted agreement in place, however, practitioners note that enforcement remains genuinely difficult unless the buyer's intellectual property is separately registered in China and the buyer has some form of registered legal presence there — an NNN agreement reduces risk and gives a basis for legal action, but it is not a guarantee against IP misuse on its own.

FAQ

What does NNN stand for?

Non-Disclosure, Non-Use, and Non-Circumvention — three separate protections combined into a single agreement, each addressing a different way a supplier could misuse shared information.

Is an NNN agreement the same as an NDA?

No. Both include a non-disclosure provision, but an NNN agreement adds non-use and non-circumvention clauses that a standard NDA does not typically include, and it is generally drafted for enforceability under PRC law rather than a foreign jurisdiction^[2][5].

When do I actually need an NNN agreement instead of an NDA?

Generally before sharing product designs, technical specifications, or customer and supplier contact information with a China-based manufacturer — any situation where the supplier could plausibly use what they learn to compete with you or go around you^[1][4].

Does signing an NNN agreement guarantee my IP won't be copied?

No. It significantly reduces risk and creates a legal basis for action if a breach occurs, but effective enforcement typically also requires registering the relevant IP in China and having some form of legal presence there.

Should an NNN agreement be written in English or Chinese?

Both. Bilingual agreements — English and Chinese — are the common practice, since an English-only contract can face practical and legal obstacles if enforcement in a Chinese court ever becomes necessary.
