NNN Agreement Guide: Protecting Your IP When Sourcing from China, Vietnam, and Beyond
An NNN agreement is a contract that includes Non-Disclosure, Non-Use, and Non-Circumvention clauses to protect your intellectual property and business relationships when working with manufacturers, particularly in China and Vietnam. It goes further than a standard NDA by preventing a factory from copying your product, using your designs for other clients, or going around you to sell directly to your customers.
If you are sourcing a custom or proprietary product overseas, an NNN agreement should be one of the first documents you send to a potential manufacturer, before sharing detailed designs or specifications.

Why a Standard NDA Is Not Enough
Most buyers are familiar with Non-Disclosure Agreements. NDAs work well in Western legal systems where the primary concern is that someone will leak your trade secrets to the public. But when you are working with an overseas manufacturer, public disclosure is rarely the actual risk.
The real risk is that the factory uses your information for its own benefit. A manufacturer could take your product design and produce a competing version for another buyer, or even sell it directly under a different brand. A standard NDA does not address this because it only covers disclosure to third parties, not internal use by the recipient.
This is why NNN agreements were developed specifically for sourcing relationships in China and Vietnam. They close the gaps that make NDAs ineffective in manufacturing environments where the supplier has the tooling, materials, and production knowledge to replicate your product.
The Three Components of an NNN Agreement
Each letter in "NNN" represents a distinct layer of protection. All three work together to cover the most common ways a manufacturer could misuse your information.
Non-Disclosure
This clause prevents the manufacturer from sharing your confidential information with anyone outside the agreed scope. This includes product specifications, technical drawings, supplier lists, pricing structures, and business strategies. It functions similarly to a traditional NDA but is drafted within a legal framework enforceable in the manufacturer's country.
Non-Use
The Non-Use clause is what separates an NNN from a standard NDA. It prohibits the manufacturer from using your proprietary information to benefit anyone other than you. If you share a custom mold design, the factory cannot use that design to produce units for another buyer or for its own product line. Without this clause, a factory in China or Vietnam could legally argue that using your design internally does not violate a simple non-disclosure provision.
Non-Circumvention
This clause prevents the manufacturer from bypassing you to deal directly with your customers, distributors, or end buyers. In sourcing, circumvention is a real and common problem. Once a factory knows who your buyers are, they have an incentive to cut you out and sell directly at a lower price. The Non-Circumvention clause creates a contractual penalty for doing so.
When Do You Need an NNN Agreement?
Not every sourcing situation requires a full NNN agreement. If you are buying a standard, off-the-shelf product with no customization, there may be limited proprietary information to protect. But in many cases, an NNN is strongly recommended.
Before Sharing Product Designs or Specifications
The right time to present an NNN agreement is before you share any detailed product information with a factory. Once a manufacturer has your CAD files, tech pack, or engineering drawings, the information is out of your hands. At Cosmo Sourcing, we advise clients to have an NNN signed before sharing detailed specs during the manufacturer vetting process.
When Developing a Custom or Proprietary Product
If the product involves original design work, proprietary formulations, unique tooling, or any innovation that gives you a competitive advantage, an NNN agreement is essential. This applies whether the manufacturer is doing the development work for you or simply producing to your specifications.
When Working with a New Supplier
Even if your product is not highly proprietary, an NNN agreement is a good practice when starting a new supplier relationship. The Non-Circumvention clause alone is valuable because it protects your customer relationships and supply chain position. Experienced factories in Vietnam and China are accustomed to signing NNN agreements and generally view the request as a sign that you are a serious, professional buyer.
When Sourcing Across Multiple Factories
If you are getting quotes from several manufacturers for the same product, each factory receives your specifications. Without NNN agreements in place, any of those factories could use your designs even if you never place an order with them. This is particularly relevant for buyers exploring Vietnam as an alternative to China, who may be contacting factories in both countries simultaneously.
How to Make an NNN Agreement Enforceable
An NNN agreement is only as strong as its enforceability. Several factors determine whether a court would actually uphold the agreement if a breach occurs.
Draft It Under the Manufacturer's Local Law
One of the most common mistakes buyers make is using a contract governed by their home country's legal system. A U.S. or EU court judgment is extremely difficult to enforce against a Chinese or Vietnamese factory. The agreement should specify that disputes will be resolved under the laws of the country where the manufacturer operates and in its courts. This means Chinese law and Chinese courts for a Chinese factory, or Vietnamese law and Vietnamese courts for a Vietnamese supplier.
Write it in the Manufacturer's language.
If your agreement is heard before a local court, the judge will work from the local-language version. Having your NNN written in Chinese (for China) or Vietnamese (for Vietnam), with the local language version designated as the controlling version for legal purposes, removes translation disputes and speeds up enforcement. An English translation should be maintained for your own reference.
Include Specific Liquidated Damages
Vague penalty clauses are difficult to enforce. Instead, specify a concrete monetary amount as damages per breach. Chinese and Vietnamese courts are generally more willing to enforce contracts with clearly defined financial penalties because they simplify the judgment process. Setting the amount high enough to be a meaningful deterrent is important, as it also makes prejudgment asset seizure more straightforward in some jurisdictions.
Define Confidential Information Precisely
Broad, catch-all definitions of "confidential information" can weaken enforceability. Be specific about what is being protected: product designs, technical specifications, mold tooling, customer lists, pricing information, and any proprietary processes. The more precisely you define what is covered, the easier it is to prove a breach occurred.
Common Mistakes That Weaken NNN Agreements
Having worked with thousands of clients on their sourcing projects, we have seen patterns in how NNN agreements fail to provide the intended protection.
Using a Generic Template Without Customization
Free templates found online may not account for the specific legal requirements of the country where your manufacturer operates. Chinese and Vietnamese contract law differ in their standards for enforceability, penalty clauses, and dispute resolution. A one-size-fits-all template is better than nothing, but it often leaves critical gaps.
Failing to Cover Subcontractors
Many factories subcontract portions of production to other facilities. If your NNN agreement only binds the primary manufacturer, any subcontractor they use is under no obligation to protect your information. Make sure the agreement requires the manufacturer to impose the same protections on any third party they involve in your production.
Skipping the Agreement Because a Factory Resists
Some manufacturers push back on signing NNN agreements. This can happen for legitimate reasons (they want their own legal team to review it) or concerning reasons (they do not want to be bound by the restrictions). Either way, a factory's willingness to sign an NNN is itself a useful data point during supplier evaluation. A reputable, export-focused manufacturer will understand the request and respond professionally.
Not Pairing the NNN with Other IP Protections
An NNN agreement is a contractual tool, not a complete IP strategy. For stronger protection, consider registering your trademarks and designs in the country of manufacture. In China, for example, trademark registration follows a first-to-file system, meaning someone else could register your brand name before you do. An NNN agreement protects your relationship with a specific manufacturer, while registered IP rights protect you against anyone in that market.
