Practical Answer — China Supplier Agreements
Is an NDA Enough When Manufacturing in China?
By Peter Lin, Founder, China IP Gateway · June 2026
In short
In most China manufacturing situations, a standard NDA is not enough. An NDA covers disclosure, but the real risks with Chinese suppliers usually involve use and circumvention — a factory making a modified version, producing for another buyer, or registering your brand. What you usually need is a China-enforceable NNN agreement (Non-disclosure, Non-use, Non-circumvention), signed and stamped before product files are shared. If you are about to send drawings, a CAD file, a BOM, or any product specification to a Chinese factory or supplier, an NDA is generally not enough — an NNN is usually the right instrument.
Why Founders Ask for an 'NDA' — and Why It Falls Short
A standard NDA focuses on confidentiality: one party should not disclose confidential information. That matters, but in real manufacturing projects the risk is broader than disclosure alone.
When a foreign brand sends product files to a Chinese factory, the primary question is usually not whether the factory will pass those files to a third party. It is whether the factory will use those files to produce for another buyer, whether a related company will file your brand in China, whether the contracting entity is the right one, and whether you have any recourse after the relationship ends.
An NDA, by design, does not address any of those questions.
What 'NDA Breach' Rarely Looks Like in China
The supplier may never openly leak anything. Instead a related company applies for a similar trademark, the factory uses the concept for another customer, the contracting and payment entities differ, or the supplier keeps using your images and packaging after talks end — and you cannot prove what was disclosed, when, and to whom.
In each of these cases, a standard NDA may not give you the legal basis to act. The supplier may argue, technically correctly, that it did not 'disclose' anything.
What a Well-Structured China NNN Should Cover
Confidentiality — restricting disclosure of your product, brand, and commercial information
Non-use — prohibiting the supplier from using your information for its own benefit or for other buyers
Non-circumvention — preventing the supplier from bypassing you to work with your customers, distributors, or partners directly
No unauthorized IP filing — explicitly prohibiting the supplier from filing trademarks, designs, or patents based on your project
No misleading market use — preventing claims of being an official or exclusive partner
Post-termination obligations — ensuring obligations survive the end of the relationship
Evidence structure — recording what was disclosed, when, and to whom
The Practical Sequence for Foreign Brands
China Trademark Check and Filing Strategy
Before deep factory disclosure. Brand capture is a risk the NNN alone may not fully prevent.
Supplier Identity Verification
Confirm the real contracting party before signing. The entity that signs must be the one receiving files and payment.
China-Enforceable Bilingual NNN
Signed and properly chopped before meaningful product files are shared.
Controlled Disclosure
Share under the NNN with a disclosure log. Mark materials confidential and confirm receipt.
Manufacturing and Exclusivity Agreement
When production terms become real — tooling, samples, exclusivity, and product-improvement terms.
Frequently Asked Questions
Is an NDA ever enough for China manufacturing?
Sometimes for very early, low-exposure talks. Once you share designs, tech packs, or samples, an NDA's disclosure-only scope is usually too narrow.
What does NNN stand for?
Non-disclosure, Non-use, and Non-circumvention — three protections that work together in a China supply-chain context.
When should the NNN be signed?
Before detailed product files, packaging, tooling information, or launch materials are shared, and ideally after verifying the supplier's real legal identity.
Should trademark filing come before or after the NNN?
In many cases the China trademark check should happen first, because brand capture is a risk an NNN alone may not fully prevent.
