NNN Agreements vs NDAs: Protecting IP When Manufacturing in China

If you're sourcing custom designs from China — anything where you're sharing your CAD files, technical drawings, or detailed specifications — the question of legal protection comes up quickly. Most importers default to using a Western NDA (non-disclosure agreement). Most importers don't realise that Western NDAs are essentially unenforceable in China.

The Chinese-law equivalent is the NNN agreement. This guide explains why it works, what it must contain, and how to use it correctly.

Why Western NDAs don't work in China

Three structural reasons:

1. Chinese courts don't recognise foreign jurisdiction. A Western NDA naming "Delaware courts" or "London courts" as the venue for disputes can't be enforced in a Chinese court. The court will dismiss based on forum.

2. Common-law concepts don't translate. Western NDAs use concepts like "good faith," "reasonable efforts," "industry standard" — all of which depend on common-law interpretation. Chinese civil law doesn't interpret these the same way; courts often find them too vague to enforce.

3. NDAs typically only address disclosure. A Western NDA prohibits "disclosure" of confidential information. But the more common harm in Chinese manufacturing isn't disclosure to third parties — it's the factory using your design to produce products for itself or other clients (which doesn't require disclosure to anyone). The NDA doesn't cover this.

The combined effect: an importer holding a Western NDA against a Chinese factory has limited practical recourse if the factory misuses the design.

What NNN means

NNN stands for Non-disclosure, Non-use, Non-circumvention:

Non-disclosure: the supplier cannot share your information with third parties.

Non-use: the supplier cannot use the information for their own products or for other clients. This is the critical clause Western NDAs typically lack.

Non-circumvention: the supplier cannot bypass you to sell directly to your customers.

Each of these addresses a specific real-world risk in Chinese manufacturing relationships.

What a working NNN includes

A properly drafted NNN agreement includes:

1. Definition of confidential information. Specific list: CAD files, technical drawings, samples, customer lists, pricing information, etc. Less ambiguous than "all confidential information."

2. Non-disclosure clause. The supplier and their employees, subcontractors, agents cannot share with anyone outside the agreement.

3. Non-use clause. The supplier cannot use the information for any purpose other than producing the buyer's order. Specifically prohibits using the design for other clients, internal products, or replication.

4. Non-circumvention clause. The supplier cannot directly contact or sell to the buyer's customers, distributors, or end users.

5. Specific damages provision. Pre-agreed damages (liquidated damages) for each type of breach. Specific dollar amounts. This is what Chinese courts can enforce more readily than equitable remedies like injunctions.

6. Term. Typically 5–10 years. Indefinite confidentiality is often unenforceable; defined terms work.

7. Chinese law jurisdiction. Specifically: "This Agreement shall be governed by the laws of the People's Republic of China. All disputes arising out of or in connection with this Agreement shall be submitted to [specific court / arbitration body in China]."

8. Chinese language version. The Chinese version is what the court enforces. Either:

• Chinese-only (with informal English translation for buyer reference), or
• Bilingual with Chinese version controlling

9. Signing party identification. The proper Chinese legal entity name (the same one on the proforma invoice). The legal representative's signature plus company seal (chop). Not just an English signature.

Drafting your NNN

Don't use a generic template. Online NNN templates exist but they're often:

• Drafted under wrong jurisdiction
• Missing key clauses for your specific risk
• Not properly translated
• Missing local procedural requirements

Hire a Chinese-qualified lawyer. A properly drafted NNN costs $300–$1,500. For most importers, the right approach is:

• Use a US/UK-China specialist firm familiar with both jurisdictions
• Or find a Chinese law firm directly (often cheaper)

Specialised firms include:

• Harris Bricken (Seattle/Beijing) — well-known China NNN specialists
• Dentons (large international with Chinese practice)
• King & Wood Mallesons (Chinese with international reach)
• AsiaIP and similar IP-specialist firms

For ongoing relationships, develop a template with your lawyer that you can adapt for new suppliers.

When to sign

Critical timing rule: before sharing any technical detail.

Once you've shared CAD files, detailed specifications, or sample products, the practical leverage is gone. The factory has the information; signing an NNN after-the-fact only protects against future use, not past use.

The right sequence:

1. Initial conversation with factory (general product description, no specifics)
2. Sign NNN
3. Share technical specifications, CAD, samples
4. Move into commercial negotiation

If a factory refuses to sign an NNN before you've shared specs, that's a meaningful signal about their intent. Walk away.

What an NNN doesn't protect against

NNN is a contractual remedy. It doesn't substitute for:

• Patent protection. Even with an NNN, if the factory uses a non-patented design, the design is in the public domain and others can use it. File Chinese utility model patents on innovative designs (cheap, $300–$600 — see our IP guide).
• Trademark registration in China. First-to-file system. NNN doesn't prevent a third party (not the factory) from registering your trademark. Register your mark in China.
• Production-line discipline. NNN doesn't enforce internal QC. Pair with a quality control specification.
• Wire fraud. NNN doesn't protect against the supplier-side fraud patterns covered in our scams guide.

NNN is one component of a complete IP/risk-protection stack, not the whole stack.

Using an NNN — practical mechanics

Step 1: identify counterparty. The proper Chinese legal entity (matches the proforma invoice). Verify on gsxt.gov.cn.

Step 2: customise template. Specific products, specific information categories, specific damages.

Step 3: translate. Ensure Chinese version is accurate. Bilingual is preferred; specify which version controls in case of inconsistency.

Step 4: sign. Both parties sign, both apply company seal (chop). Date the signing.

Step 5: store. Keep original in a secure location. Save digital copies (with high-resolution chop visible).

Step 6: reference. The supply contract should reference the NNN by date and parties.

Common NNN mistakes

1. Signing with a sales rep, not the legal entity. Sales reps don't have authority to bind the factory. Make sure the legal representative (with proper company seal) signs.

2. NNN signed after CAD shared. As discussed — too late to protect retrospectively.

3. Generic clauses without specifics. "Buyer's information" is too vague. List specific categories.

4. No specific damages. Without pre-agreed damages, courts often award only nominal damages even on clear breach.

5. Wrong jurisdiction. US, UK, or HK jurisdiction won't enforce in mainland China. Specify a Chinese court or arbitration body.

6. NNN with a trading company while production is at a different factory. Make sure the actual manufacturing entity is bound, not just the trading intermediary.

Cost-benefit math

For an importer with custom designs, IP investment scaled to product value:

For a $100k+ order, $3,300 of IP protection is 3.3% of order value — overhead but cheap relative to what's protected.

For a $5k order, $800 might feel proportionally larger — but it's still trivial relative to the consequences of design theft.

A worked example

A US homewares brand wanted to source 800 units of a custom silicone kitchen tool with proprietary design from a Dongguan factory. We:

1. Initial conversation: general description only.
2. NNN drafted by Chinese-qualified lawyer ($400 cost). Signed before specifications shared.
3. Filed Chinese utility model patent on the tool's distinctive design ($400, 8-month issue).
4. Filed Chinese trademark on brand name in class 21 ($800 cost, 9-month issue).
5. Shared CAD with factory.
6. Sample iteration over 3 weeks.
7. Production order placed under standard supply contract referencing NNN.

Total IP protection cost: $1,600. Order value: ~$3,000 first batch, scaled to $30k+ over 18 months.

Two years later: no IP issues. The factory knows we have the patent + trademark + NNN protection — and continues to produce because the relationship is working.

When you don't need an NNN

NNN is overkill for some sourcing scenarios:

• Pure commodity products — sourcing standard items (basic mugs, basic apparel) where you have no proprietary design
• Off-the-shelf ODM products — using factory's existing product with cosmetic customisation only
• Very small one-off orders — where the cost-benefit doesn't justify

If you're sharing proprietary information (designs, formulations, data), use an NNN. If you're not, don't bother.

The bottom line

Western NDAs don't work in China. NNN agreements (Non-disclosure, Non-use, Non-circumvention) drafted under Chinese law with Chinese jurisdiction do work — and are dramatically more enforceable than NDAs.

Sign an NNN before sharing technical detail. Pair with Chinese utility model patent and Chinese trademark registration for full IP protection. Budget $300–$1,500 for the NNN itself. Trivial cost relative to what you're protecting.
