In short: what is an NNN agreement and do you need one?

An NNN agreement (Non-Disclosure, Non-Use, Non-Circumvention) is a contract signed under Chinese law that stops a manufacturer from sharing your product design, using it to make copies, or going around you to sell directly to your customers or suppliers. Unlike a standard NDA, it is written in Chinese, enforceable in a Chinese court, and specifically closes the two gaps a Western-style NDA leaves open: the factory using your design for its own products, and the factory approaching your buyers directly. If you are sending a Chinese manufacturer a product design, mould, or formulation before you have a signed purchase order, you need one.

Why doesn't a normal NDA protect you in China?

A standard NDA only stops disclosure, meaning the factory technically cannot show your design to a third party, but it does not stop the factory itself from manufacturing and selling a near-identical product once your relationship ends, and it does little to stop the factory contacting your distributors directly. An NNN closes both gaps, and because it is drafted for enforcement inside China rather than in a Western court, it is the version that actually holds up if you ever need to act on it.

What makes an NNN agreement actually enforceable in China?

Four things matter more than the clauses themselves: the agreement needs to be in Chinese as the governing language (a English-only version is much harder to enforce), it needs to specify a Chinese court or arbitration body rather than your home country's courts, it needs the factory's official company chop (seal) rather than just a signature, and it needs to name the specific legal entity that owns the factory, not just a sales agent or trading company you have been emailing. A template downloaded off the internet that skips any of these four is largely decorative.

What does a China NNN agreement template usually miss?

Generic templates rarely specify a concrete, defensible damages figure, which matters because Chinese courts want a stated amount rather than an open-ended claim. They also often forget to name every affiliated factory the manufacturer might subcontract to, leaving a loophole where production quietly shifts to a related company outside the agreement. A properly localised NNN, ideally reviewed by someone with on-the-ground experience of how Chinese manufacturing groups are actually structured, closes both gaps.

How can a sourcing agent reduce IP risk before you even need an NNN?

The strongest protection is never needing to test the agreement in court. Working through a sourcing agent who vets factories on the ground, keeps your design and tooling details compartmentalised across suppliers, and knows which manufacturing groups have a track record of running side production, cuts the leakage risk long before a dispute happens. Epic Sourcing's bilingual China and Vietnam teams handle supplier vetting and NNN coordination directly through our end-to-end sourcing service, so Singapore and SEA brand owners are not negotiating IP protection by email from a different time zone. If you are specifically looking for a vetted agent on the ground, see our guide to finding a sourcing agent in Singapore.

NNN vs standard NDA: what changes

Frequently asked questions

Is an NNN agreement the same as an NDA?

No. An NDA only addresses confidentiality. An NNN adds Non-Use (the factory cannot manufacture your design for anyone else, including themselves) and Non-Circumvention (the factory cannot bypass you to sell to your customers or buy from your suppliers directly).

Do I need an NNN agreement for every supplier?

You need one before sharing any proprietary design, mould, formulation, or packaging artwork with a factory you have not signed a production agreement with yet. For off-the-shelf products with no custom IP involved, the risk is lower, though a basic NNN is still good practice.

Will a Chinese factory actually sign an NNN agreement?

Reputable manufacturers that work with international brands regularly are generally comfortable signing one, since larger factories are used to it. A factory that refuses outright, or negotiates aggressively to remove the Non-Use and Non-Circumvention clauses specifically, is a warning sign worth taking seriously.

How much does an NNN agreement cost to put in place?

Using a properly localised Chinese-language template reviewed by someone familiar with Chinese contract law is far cheaper than a dispute later, typically a few hundred to low thousands of US dollars depending on complexity, well below the cost of a single knocked-off production run.

Can I use the same NNN agreement for a Vietnam manufacturer?

No — Vietnam has its own legal system and contract requirements, so a China-specific NNN will not transfer directly. The same underlying protections (non-use, non-circumvention, local governing law and language) still apply, just drafted for Vietnamese enforcement instead.

Once your IP is protected, the next steps are usually shipping and customs compliance — if you are shipping into the US, see our guide on who the importer of record actually is, and if your order volumes are large enough to benefit from duty deferral, our guide to bonded warehousing explains how that works across each market.

How Epic Sourcing helps

Epic Sourcing's bilingual teams on the ground in China and Vietnam handle supplier vetting, NNN coordination, and factory relationship management directly, so Singapore and SEA brand owners are not trying to protect their IP by email from a different time zone.
