NNN Agreements: Protecting Intellectual Property When Working with China

Posted on February 17, 2026

As global companies increasingly source products, manufacture goods, or collaborate with Chinese partners, protecting intellectual property (IP) has become a critical concern. One of the most widely used legal tools for safeguarding IP in China is the NNN Agreement — short for Non-Disclosure, Non-Use, and Non-Circumvention.

What is an NNN Agreement?

An NNN Agreement (which is basically a more comprehensive form of NDA) is a contract between a foreign company and a Chinese manufacturer, supplier, or business partner that protects the company’s IP and proprietary information.

The three main components of an NNN Agreement are:

1. Non-Disclosure (ND)

• The Chinese party agrees not to disclose confidential information provided by the foreign company with others.
• Confidential information can include designs, formulas, product specifications, supplier lists, and business plans.

2. Non-Use (NU)

• The Chinese party agrees not to use the foreign company's IP or confidential information for their own benefit or for the benefit of a third party.

3. Non-Circumvention (NC)

• Prevents the Chinese party from by-passing the foreign company to deal directly with suppliers, manufacturers, or customers introduced by the foreign company.

Why are NNN Agreements Important?

When sourcing products or manufacturing in China, businesses face risks such as:

• IP theft: replication of designs, formulas, or product innovations.
• Unauthorised production: manufacturers selling copies of your product to your competitors.
• Supplier/customer circumvention: losing access to key suppliers or customers due to direct deals made without your knowledge.

NNN Agreements provide a legal mechanism to enforce IP rights and prevent these risks.

Key Legal Aspects of NNN Agreements

1. Scope of Confidential Information

• Clearly define what constitutes confidential information.

2. Ownership of IP

• Specify that all IP, designs, or improvements belong exclusively to the foreign company. You may wish to deal with modification or improvements to the IP in the NNN Agreement, but I personally prefer to deal with them in the supply or manufacturing agreement as those issues often require careful consideration and negotiation.

3. Duration and Termination

• Set clear terms for how long the agreement applies.

4. Governing Law and Dispute Resolution

• Choose the appropriate governing law for enforceability.
• Dispute resolution is often through CIETAC or HKIAC arbitration or local courts, with carefully drafted jurisdiction clauses.

5. Enforceability Considerations

• Depending on the chosen governing law in your NNN Agreement, the NNN Agreement must comply with the contract law in the chosen jurisdiction.
• The contract should be signed in accordance with the Chinese law (accompanied by the use of the company seal).

Practical Tips for Using NNN Agreements

• Sign before sharing designs or product specifications: Never disclose IP until the agreement is in place.
• Tailor the agreement: standard templates may not fully address your specific IP risks.
• Monitor compliance: conduct regular audits and inspections of the manufacturer's production.
• Combine with other protections: register trademarks, patents, and designs in China for additional legal security.
• Enforce proactively: include clear remedies for breach, such as injunctive relief or damages.

Common Misconceptions

• NNN Agreements alone are not enough: while NNN Agreements are a critical early protective measure, they are not a substitute for IP registration or regulatory safeguards. NNN agreements are typically entered into at a preliminary stage, often before a party has decided whether it will proceed with a particular supplier or transaction. Their primary purpose is to allow discussions, sampling and evaluation to occur while limiting misuse of confidential information. However, once a commercial relationship progresses, additional and more sophisticated risk allocation becomes necessary. Complex intellectual property issues, such as ownership of modifications, improvements, derivative works, tooling, and jointly developed IP, are usually better addressed in a detailed supply or manufacturing agreement where:
  • ownership can be precisely defined,
    
  • rights to use and commercialise can be allocated, and
  • obligations to assign or licence future developments can be documented.

Relying on an NNN agreement alone will rarely provide sufficient protection for long-term production agreements.

• They prevent all theft: enforcement can still be challenging, so combine with monitoring, audits and IP registration.
• One-size-fits-all agreements work: Each supplier and product may require specific clauses to address the unique risks involved.

Conclusion

NNN Agreements are a critical legal tool for foreign companies engaging with Chinese partners. They help protect against the misuse of confidential information, IP theft, and business circumvention. When properly drafted and implemented alongside IP registration, quality control protocols, and compliance measures, NNN Agreements enable businesses to navigate the legal and commercial risks of sourcing and manufacturing in China safely and effectively.
