China NNN Agreements: The 10 Most Asked Questions
A China NNN Agreement is useful when you need to disclose commercially valuable information to a Chinese company before you can sign the full development or manufacturing contract. This most often happens while you are evaluating factories and need to share enough information for them to quote, assess feasibility, or make a prototype.
For a deeper look at when these agreements make sense—and when they do not—see China NNN Agreements: The Hard Truth.
1. What is a China NNN Agreement?
A China NNN Agreement addresses three risks: non-disclosure, non-use, and non-circumvention. Non-disclosure is the familiar part. The Chinese company agrees not to reveal protected information. Non-use is usually more important in a manufacturing relationship because it prevents the recipient from using your information for an unauthorized purpose, such as making your product for someone else or developing a competing product. Non-circumvention restricts the recipient from using the relationship to go around you to customers, suppliers, or other business contacts.
The protection need not turn entirely on whether every drawing, price, customer name, or product feature qualifies as a trade secret. The contract can define what the parties are protecting and what the recipient is prohibited from doing with it.
2. How is an NNN different from a standard NDA?
A conventional U.S. NDA often has two problems in a China manufacturing deal: it prohibits too little and provides for enforcement in the wrong place. Many NDAs focus on disclosure. That misses a common manufacturing risk. A factory can keep your drawings completely secret and still use them to make a competing product, supply another customer, or cut you out of a business relationship.
The enforcement provisions can be just as troublesome. A contract calling for U.S. law and litigation in a U.S. court is a poor starting point when the defendant operates in China, the conduct occurs there, and the assets you hope to reach are there. Winning a U.S. judgment does not mean you will be able to turn that judgment into money or immediate leverage in China. Translating that NDA into Chinese does not fix either problem.
3. When should the NNN be signed?
Sign it before you disclose anything worth protecting. Once you send the CAD files, specifications, prototype, pricing, customer information, or manufacturing know-how, you cannot undo the disclosure. Waiting until afterward also creates an avoidable factual dispute over what the manufacturer received before the agreement took effect.
NNNs are especially useful during factory selection. You may need to give several manufacturers enough information to determine whether they can make your product and at what price, even though only one will ultimately get the business. Each candidate that receives sensitive information should be dealt with before the information goes out. Once you select the manufacturer, the contracting changes.

4. What information does it cover, and how long does the protection last?
The NNN should cover the information that matters to the deal, not just documents somebody remembered to stamp “Confidential.” For a manufacturing project, that typically includes drawings and specifications, pricing, customer information, and technical or commercial know-how that gives your business an advantage. The wording should also match the way information will move. Engineers may discuss design changes on WeChat. Prototypes may go back and forth. Specifications may evolve over several months. An agreement written as though every protected disclosure will arrive in a formally labeled PDF does not match how these projects work.
Duration depends on the information and the transaction. Where disclosures continue over time, we sometimes use a negotiated fixed period that runs from the last protected disclosure rather than from the date the agreement was signed. That is more sensible than promising “everlasting protection” for information whose commercial value may disappear much sooner.
5. What makes a China NNN Agreement enforceable and useful?
Start with the right company. Then make the prohibited conduct clear, impose responsibility for misuse within the manufacturer's network, provide sensible consequences for breach, and choose an enforcement structure that works where the defendant and its assets are located. Vague prohibitions against “misusing confidential information” leave too much room for argument. The agreement should deal with the ways manufacturers create problems in the real world: using your design for another customer, making competing products, passing sensitive information to an undisclosed subcontractor, or approaching customers they learned about from you. A court or tribunal should be able to identify the obligation, the breach, and the remedy without reconstructing the parties' intentions from emails.
A refusal to sign also tells you something. Large manufacturers sometimes have legitimate objections to particular provisions or insist on a different dispute mechanism. Those points can be negotiated. A prospective factory that wants your specifications while refusing meaningful limits on what it can do with them presents a different problem.
No contract makes a dishonest manufacturer honest. An NNN gives you leverage and a contractual claim if the manufacturer crosses the line. The value of that claim depends heavily on whether you bound the right defendant, whether it has assets you can reach, and whether you are prepared to enforce the agreement.
6. Why do the exact Chinese company name, governing language, law, and forum matter?
You need a contract with the company capable of causing the harm. We have seen what happens when the wrong company signs. In one matter, the agreement bound a Hong Kong sourcing company while the Mainland factory holding the CAD files had signed nothing. The factory later opened a second production line for a competitor. The company with the information and manufacturing capacity sat outside the contract. We discuss the problem in The RedNote Contract Lesson for Companies Doing Business in China.
Use the Mainland counterparty's exact registered Chinese legal name rather than an English trade name, a salesperson's email signature, or whatever appears on a website. We also generally want the verified company to affix its official company chop, with the Chinese name on the chop matching the company named in the agreement.
For a contract intended to be enforced against a Mainland manufacturer in a Chinese court, we generally prepare both Chinese and English versions so both sides understand what they are signing, but only one language controls. That language is usually Chinese. Making both versions equally controlling creates an unnecessary fight if the two texts differ. Why Your China Manufacturing Agreements Should Almost ALWAYS Be in Chinese explains why. Chinese as the controlling language does not rescue weak drafting. It reduces translation and interpretation disputes. The governing law and forum should likewise be selected with enforcement in mind, rather than copied from a domestic contract.
7. How do contract damages and asset preservation actually work?
Agreed contract damages put a specified financial consequence on a specified breach. They do not freeze bank accounts or seize equipment by themselves. Article 585 of China's Civil Code permits parties to agree in advance on damages for breach and permits a court or arbitration tribunal to adjust an amount that is too low or excessively high. The Supreme People's Court added more guidance in 2023. Under Article 65 of its interpretation of the Civil Code's contract provisions, agreed damages that exceed the loss caused by the breach by more than 30 percent generally may be treated as excessively high. Courts also look at the transaction, performance, fault, and surrounding circumstances.
That does not make 130 percent of expected loss a magic drafting formula. The damages number needs a defensible relationship to the harm. An enormous number pulled from the air does not make the agreement stronger. Asset preservation requires a separate court process. Under the Supreme People's Court's rules on property preservation, when a court requires security for a preservation application made during litigation, the security generally cannot exceed 30 percent of the amount sought to be preserved. Pre-suit preservation ordinarily requires security equal to the amount requested, though the court has discretion in special circumstances. Insurance and qualifying guarantees can also be used as security.
This is why contract damages matter without being magical. They put a number on the breach and can strengthen the enforcement strategy. The court decides whether assets get frozen.
8. Does the NNN cover affiliates, subcontractors, engineers, and other recipients?
It should make the signing company answer for what happens when it passes your information into its manufacturing network. Factories routinely involve engineers, component suppliers, related companies, and subcontractors. If the manufacturer can escape liability by saying, “Our subcontractor did it,” the protection has a hole in it. The contract should make the manufacturer responsible for unauthorized disclosure or use by the people and entities to whom it gives the protected information.
That still does not turn every affiliate into a party to the agreement. Separate companies remain separate legal entities. When another company will receive particularly sensitive information, hold critical tooling, or perform an important part of the work, consider binding that company directly rather than relying entirely on the first manufacturer's promise.
9. When do I not need a separate China NNN Agreement?
You do not need an NNN merely because the other party is Chinese. An NNN can be an answer to a problem you do not have. If you are buying ordinary off-the-shelf goods and disclosing no commercially valuable information, there may be little for an NNN to protect. You can also skip the separate NNN when you have already selected the manufacturer and can sign a comprehensive Manufacturing Agreement before sending anything sensitive. That agreement can contain the necessary non-disclosure, non-use, and non-circumvention provisions.
Sometimes the more urgent problem is your trademark. An NNN binds the companies that sign it. A China trademark registration gives you rights against companies that never did. If your brand will appear on goods, labels, packaging, or export materials in China, deal with the trademark separately and early. See China NNN Agreement or Trademark Registration? You Usually Need Both.
10. Is an NNN enough once I choose the manufacturer?
No. Once you choose the manufacturer, you need a contract that governs production. A Manufacturing Agreement deals with the issues the NNN was never meant to handle, including product quality, delivery, payment, tooling, and remedies for defective or late goods. If the Chinese company will help develop or engineer the product, you may need a Product Development Agreement before that work begins.
We dealt with one company that learned this too late. Its product design emerged through back-and-forth work with the Chinese factory, but the company had relied on an NNN instead of a Product Development Agreement that clearly allocated ownership of the resulting IP. When the relationship deteriorated, the contract did not answer the ownership question. The High Cost of China Contract Mistakes tells that story.
Tooling presents a similar risk. In another matter, a factory demanded a 34 percent price increase while holding the buyer's molds, designs, and customer information. Replacing the molds caused a production shutdown that nearly bankrupted the buyer. China Manufacturing Contracts: When One Agreement Is Not Enough explains how separate NNN, development, manufacturing, and tooling protections fit together.
Use the NNN for the disclosure risk that exists while you are evaluating a factory. Once development or production begins, the operative contracts need to do the rest.
