NDA and IP Protection When Working with Chinese Factories

A good NDA is the foundation of any OEM relationship with a Chinese factory. A bad NDA gives false security. Most Western buyers use a US-style NDA template pulled from the internet and assume it will protect them in a Chinese court. It will not. Chinese courts enforce NDAs drafted specifically for Chinese legal context, with Chinese-law clauses, and almost always not templates from California. This article covers what a Chinese-enforceable NDA looks like, what clauses matter, and how to use it effectively. Written from Hefei, China, by Eviehome (Hefei Ecologie Vie Home Technology Co., Ltd.).

Why US NDA templates fail in China

A typical US NDA template has these problems when used against a Chinese factory:

• Jurisdiction is a US state: Chinese courts will not enforce a judgment from a California court against a Chinese entity with no US assets.
• “Confidential information” is too broad: Chinese courts require specific identification of what is confidential.
• No liquidated damages: without a specific cash penalty clause, proving actual damages in court is difficult.
• Written in English only: Chinese courts need a Chinese version. A Chinese-only or bilingual version is enforceable; an English-only is problematic.
• No non-use and non-circumvention: standard US NDAs focus on disclosure only, not on the factory using the information internally for competing products.

The right tool is an NNN agreement (Non-disclosure, Non-use, Non-circumvention) drafted for Chinese legal context.

What is an NNN agreement

An NNN agreement is the China-specific equivalent of an NDA. It adds two clauses beyond standard confidentiality:

1. Non-disclosure: the factory cannot share your information with third parties.
2. Non-use: the factory cannot use your information for its own purposes (like producing a competing product internally).
3. Non-circumvention: the factory cannot bypass you and sell directly to your customers, suppliers or partners.

The non-use clause is critical because it covers the most common abuse: a factory producing “competing” products that happen to use your engineering and specs.

The 10 clauses a good China NNN must include

1. Clear identification of the parties

Use the full registered Chinese names of both parties (not just the English names). The factory’s Chinese legal name is on their business license. Request a copy and verify.

2. Specific definition of confidential information

List what is confidential: product specs, design files, firmware, test data, pricing, marketing plans. Avoid “any information exchanged” which is too vague for Chinese courts.

3. Non-disclosure clause

Factory cannot share confidential info with third parties, including their own subcontractors without your written consent.

4. Non-use clause

Factory cannot use the confidential info for any purpose other than producing the specific SKU you agreed on. They cannot use it to make variants, derivative products, or products for other brands.

5. Non-circumvention clause

Factory cannot contact your customers, distributors, or supply chain partners directly. They must route everything through you.

6. Liquidated damages clause

Specific monetary penalty for breach. Typical: USD 50 000 per unit of unauthorized production, or USD 100 000 minimum breach penalty. Chinese courts enforce liquidated damages when they are reasonable and specific.

7. Term of the agreement

How long does the NDA last? Typically 3 to 5 years after the end of the commercial relationship. Too short = factory can dump your design after 1 year. Too long = hard to enforce.

8. Jurisdiction and governing law

Specify a Chinese court (Beijing, Shanghai or Guangzhou IP courts are preferred) and Chinese law as the governing law. This makes the agreement enforceable where the factory is located.

9. Bilingual execution

The agreement should be in both English and Chinese, with the Chinese version being authoritative. Do not sign an English-only version.

10. Signatures with chop

The Chinese party’s signature must include their official company chop (seal). A signature without a chop is not fully binding in China.

How to draft a good NNN

Three paths:

1. Use a China-specialist lawyer: USD 500 to 1500 for a good NNN draft. Best option for first-time brands or high-value projects.
2. Use a template from a reputable source: Harris Bricken, Dezan Shira, China Law Blog all publish templates. Adapt with caution, preferably with a lawyer review.
3. Use the factory’s template: factories often provide their own NDA. Read carefully; these usually favor the factory. Mark up and negotiate.

For any project over USD 20 000 of initial investment, option 1 is worth the cost.

Who should sign

The signatory on the factory side matters:

• Legal representative of the company: the best option. Usually the CEO or an authorized person listed on the business license.
• General manager or sales director: acceptable if they have written authority to sign contracts.
• Individual engineer or salesperson: NOT acceptable. A signature from someone without authority is not binding.

Verify the signatory by asking for a copy of the business license and matching the legal representative name.

Enforcement realities

If a factory breaches the NDA, enforcement looks like:

1. Document the breach: screenshots, product photos, order records, witness statements.
2. Send a legal notice: via a China lawyer, formally demanding cessation and damages.
3. File a complaint with the local court: Chinese IP courts in Beijing, Shanghai, Guangzhou, or the local IP court where the factory is registered.
4. Court procedure: 6 to 18 months for first instance, another 6 to 12 months for appeal.
5. Enforcement: Chinese courts have gotten stricter on IP enforcement in 2020+ and regularly award liquidated damages to foreign plaintiffs.

Cost of enforcement: USD 5 000 to 30 000 for a typical case, plus lawyer fees. Worth it when the IP value is higher.

Trade secrets vs registered IP

An NNN protects trade secrets — information that is confidential and has commercial value. Registered IP (patents, trademarks) is protected separately through the state registration system. Use both:

• NNN for the stuff that is hard to register: firmware details, engineering know-how, pricing strategies, client lists.
• Registered IP for the stuff that can be registered: trademarks, design patents, utility patents, copyrights.

NNN + registered IP together give the strongest protection.

Frequently asked questions

Can I use the same NNN template for multiple factories?

Yes, as long as you adapt the party names and the specific confidential information for each project. Keep the legal structure identical so you can enforce consistently.

Should I pay a factory to sign the NNN?

No. A factory that demands payment to sign an NDA is signaling bad faith. Walk away.
