NNN Agreements: The Contract Bangladeshi Importers Sign Before Sharing a Design

You have a product idea, a set of drawings, or a sample you want copied and improved. The moment you email that to a Chinese factory for a quote, you have handed over the thing that makes your business worth anything. A Western-style non-disclosure agreement rarely protects you here. The tool that does is an NNN agreement, and most Bangladeshi buyers have never heard the term until a design turns up on a competitor’s shelf.

Why an ordinary NDA does not travel to China

A standard NDA is built around one promise: the other side will not disclose your confidential information to third parties. That is the wrong promise for a manufacturing relationship. A factory that receives your design usually has no interest in publishing it. Its interest is in using it — running your tooling on a night shift for another customer, selling “the same model” on a B2B marketplace, or quietly going around you to reach your customers directly. A pure non-disclosure clause does not stop any of that.

There is a second problem. Most NDAs a buyer downloads name a home-country court and home-country law. If a factory in Guangdong breaches it, you would have to win a judgment abroad and then try to enforce that foreign judgment in a Chinese court, which in practice is slow and uncertain. A contract that a Chinese court will not readily enforce is a contract the factory is not really afraid of.

What the three Ns cover

NNN stands for Non-disclosure, Non-use, and Non-circumvention. Each closes a specific hole:

• Non-disclosure — the factory cannot share your drawings, specifications, samples, supplier list or commercial terms with anyone else.
• Non-use — the factory cannot use your information for any purpose other than making your order. This is the clause that bars building the same product for another buyer, even without disclosing anything.
• Non-circumvention — the factory cannot bypass you to sell directly to your customers, and cannot bypass you to reach a sub-supplier or mould maker you introduced.

For a buyer developing a genuinely new product, non-use is usually the clause that matters most. It is also the one an off-the-shelf NDA leaves out entirely.

The features that make it enforceable

An NNN agreement is only as good as a Chinese court’s willingness to act on it. Practitioners who do this regularly build in a few things:

• The governing language is Chinese, or the contract is bilingual with the Chinese version controlling. A court works from the Chinese text.
• The governing law is the law of the People’s Republic of China, and jurisdiction is a specific Chinese court with authority over the factory’s registered address.
• The factory is identified by its exact registered Chinese name and unified social credit code, not just its English trading name, and the contract is stamped with the company chop, not only signed.
• There is a contractual penalty — a fixed sum payable on breach — so you do not have to prove your exact losses to recover something. Chinese courts will enforce a reasonable liquidated-damages figure.

That last point is the practical teeth. If breach costs the factory a defined, collectable amount, the night-shift copy run stops being worth it.

When to get it signed

Before the first real technical exchange. Once you have sent detailed CAD files, a full bill of materials, or a working sample, the information is out. An NNN signed after that still helps for the next stage, but it cannot un-send what the factory already has. The sequence that works is: initial contact and a rough capability check, NNN signed and chopped, then detailed drawings and samples, then tooling and pre-production. If a supplier flatly refuses to sign anything, that is information about how it treats other people’s designs.

The same logic runs alongside the sample and tooling stage. Our guides on the sample approval process and on getting a new product manufactured in China assume the paperwork is already in place.

What an NNN does not do

It is not a patent, a trademark, or a registered design. If your product is legally protectable, register the rights in China as well — China is first-to-file for trademarks, and a local actor can register your brand before you do. An NNN is a contract between you and one factory; it does not bind a second factory that reverse-engineers a unit bought on the open market. It also does not replace due diligence: a shell company with no assets can sign a beautiful NNN and simply dissolve. Check that the entity is real and trading, using the same GSXT lookup we describe in our post on reading a Chinese business licence.

Cost, drafting, and who should hold the pen

A properly drafted, China-enforceable NNN is a lawyer’s document, and the fee depends on how custom it is — a template lightly adapted sits at one end, a heavily negotiated agreement for a complex product at the other. Ask us for a quote scoped to your situation rather than assuming a number. What you should not do is use a free English template pulled off the internet and translate it with software; the clauses that matter will not survive that process, and the jurisdiction will be wrong.

If you are working through a sourcing agent, the agent can present and get the NNN chopped as part of onboarding a factory, before any drawings move. That keeps the protection in front of the disclosure instead of behind it.

A realistic example of the clause working

A buyer sends a factory full CAD files and a bill of materials to get a quote, and first has the factory sign and chop an NNN with a fixed liquidated-damages figure and jurisdiction in the local court where the factory is registered. Six months later the same product — with the buyer’s specific, non-obvious design details intact — turns up on a B2B marketplace, offered by a company that shares an address and directors with the original supplier’s trading arm.

With a downloaded NDA governed by foreign law, the buyer has a claim on paper and no practical way to enforce it. With the China-enforceable NNN, a local lawyer issues a demand citing the non-use breach and the agreed penalty sum. If it is not paid, the lawyer files in the named court and can apply for pre-judgment asset preservation — freezing a company bank account while the case runs, which in practice is what brings a defendant to the table in China. The liquidated-damages clause means the buyer has to prove the breach happened, not calculate exact lost profit, which is the difference between a claim that moves and one that stalls.

One contract or two: NNN and the manufacturing agreement

Early on, a standalone NNN is right — you need protection in place before any drawings move, and you may still be talking to several factories. Once you commit to production with one of them, fold the same three protections into a full manufacturing agreement that also covers specifications and tolerances, inspection rights, tooling ownership, defect liability, delivery terms and how the relationship ends. Keep it bilingual with the Chinese version controlling, jurisdiction in China, and the company chop applied, not just a signature.

Carry the survival language across so that non-use and non-circumvention continue after the supply relationship ends — otherwise a factory you stop buying from is suddenly free to use everything it learned. Do not let the early NNN quietly lapse when the bigger contract is signed; make the new contract expressly continue it.
