NDA vs. NNN Agreement in China: What Foreign Businesses Should Know

Should You Sign an NDA or an NNN Agreement?

If your company is planning to manufacture products in China, you may need to share confidential product drawings, technical specifications, prototypes, pricing information, or customer details with a potential supplier.

Before disclosing this information, an important question arises: should you sign a standard Non-Disclosure Agreement (NDA) or a Non-Disclosure, Non-Use, and Non-Circumvention (NNN) Agreement?

The answer depends on your business risks and the terms of the agreement—not simply its name. This article explains how to protect confidential information and product designs when working with Chinese manufacturers.

What Is an NDA?

A Non-Disclosure Agreement is designed to protect confidential information from unauthorized disclosure.

For example, your Chinese manufacturer may receive technical drawings solely to evaluate whether it can produce your product. A properly drafted NDA can restrict the manufacturer's ability to share those drawings with third parties.

However, a confidentiality obligation alone may not adequately address every manufacturing risk. Your company may also be concerned about the manufacturer's own use of the information, unauthorized production, or efforts to exploit specific business introductions. These concerns should be addressed expressly.

What Is an NNN Agreement?

NNN is a commercial term commonly used for agreements containing three categories of obligations: Non-Disclosure — the manufacturer must not disclose protected information without authorization; Non-Use — the manufacturer may use protected information only for agreed business purposes; and Non-Circumvention — the manufacturer may be restricted from using specified confidential information or business introductions to bypass your company in defined commercial transactions.

For example, the manufacturer should not use your proprietary drawings to manufacture products for its own account without authorization.

These restrictions should be carefully drafted to address legitimate business interests without unnecessarily restricting lawful independent activities. NNN is not a special statutory contract category under Chinese law. Its effectiveness depends on the actual provisions, facts, and applicable law.

Is an NNN Agreement Better Than an NDA?

Not necessarily. A well-drafted NDA may already contain strong non-use obligations and appropriate restrictions relating to customers or business opportunities. Conversely, an agreement labeled "NNN" may still contain vague definitions, excessive restrictions, or poorly drafted enforcement provisions.

Before choosing an agreement, identify the specific risks involved in your manufacturing project. For example: Will the manufacturer receive technical drawings or source code? Will it have access to your customers? Will it develop new product designs? Could it produce unauthorized quantities? Will subcontractors receive confidential information?

The contract should be designed around these questions.

How Does Chinese Law Protect Trade Secrets?

Chinese law protects qualifying trade secrets. Under China's Anti-Unfair Competition Law, trade secret protection generally requires information to: be unknown to the relevant public; have commercial value; and be subject to appropriate confidentiality measures. The law also prohibits certain unauthorized acquisition, disclosure, and use of trade secrets.

China's revised Anti-Unfair Competition Law took effect on October 15, 2025. In addition, new Trade Secret Protection Provisions issued by the State Administration for Market Regulation took effect on June 1, 2026. These rules provide further guidance on confidentiality measures and administrative protection.

Importantly, signing an NDA or NNN agreement does not automatically make every piece of business information a legally protected trade secret. Businesses should also implement practical confidentiality controls.

What Should an NDA or NNN Agreement with a Chinese Manufacturer Include?

Depending on the project, important provisions may include: Definition of confidential information — clearly identify the types of technical and commercial information to be protected; Permitted use — specify why the manufacturer may access the information and prohibit other unauthorized uses; Disclosure restrictions — limit disclosure to approved personnel and subcontractors who are subject to appropriate obligations.

Intellectual property provisions — clarify ownership of existing IP and address unauthorized trademark registration, product designs, and new development work where relevant; Return and deletion — require appropriate handling of confidential information and project materials when the relationship ends.

Consequences of breach — include suitable contractual remedies, taking account of applicable Chinese law; Dispute resolution — select an appropriate governing law and dispute resolution mechanism based on the parties and commercial circumstances.

Can You Enforce an NDA or NNN Agreement in China?

Potentially, yes. Chinese law recognizes contractual obligations, and a properly drafted agreement may provide a basis for pursuing remedies for breach. Where qualifying trade secrets are involved, statutory trade secret remedies may also be available.

However, enforceability depends on the contract's validity, the conduct involved, available evidence, jurisdiction, and other relevant circumstances. A contract should not be treated as a guarantee that a future dispute can be prevented or won.

Are High Contractual Penalties Always Enforceable?

Some foreign businesses believe that inserting a very large penalty will automatically deter misconduct. Under Article 585 of China's Civil Code, parties may agree on liquidated damages.

However, Chinese courts or arbitration institutions may adjust an agreed amount in circumstances specified by law, including where it is excessively higher than the loss caused. The amount and structure of contractual remedies should therefore be evaluated carefully.

What Should Foreign Businesses Do Before Sharing Product Information?

Before sending sensitive information to a Chinese manufacturer, consider the following steps: verify the identity of the actual Chinese contracting and manufacturing entities; identify the specific information requiring protection; assess whether trademark or other IP registration is appropriate.

Sign an agreement containing suitable confidentiality and use restrictions; control access to sensitive files and maintain disclosure records; review the manufacturing agreement before committing to production.

These steps can help reduce risk and improve your position if a dispute arises.

How Can a China-Qualified Lawyer Help?

A China-qualified lawyer can assist foreign businesses with reviewing and drafting confidentiality agreements, supplier IP provisions, and related manufacturing contracts.

Legal services may include: reviewing an existing NDA or NNN agreement; drafting project-specific confidentiality and restricted-use clauses; assessing contractual protection for product designs and technical information; reviewing supplier identity and contractual enforcement considerations; evaluating contractual remedies and potential disputes.

The appropriate scope depends on the products, information, supplier relationship, and commercial objectives.
