NNN agreements: non-disclosure, non-use, non-circumvention — and the clauses matter less than who signs them.

1. What the three Ns cover, briefly

NNN stands for non-disclosure, non-use, non-circumvention. The distinction buyers care about is the second and third:

One number is worth knowing before you rely on an English name. When I searched all 106 Chinese manufacturers on a US regulator's list by their English names, 42.5% returned nothing at all. The full search-outcome study shows what came back and why.

An NNN agreement binds a named entity, so the name has to be the registered one. This frame shows how often that resolution fails: 42.5% of searches returned no candidate, and 13.1% of returned rows were registered in a different jurisdiction than assumed. An agreement signed against an English trading name binds less than it appears to.

• Non-disclosure: do not pass the information to others. This is the part an ordinary NDA already addresses.
• Non-use: do not make the product yourself. This is usually the real fear, and a secrecy-only NDA does not obviously reach it.
• Non-circumvention: do not go around me to my customers.

That is the concept. How to word each of the three, which law and forum to choose, what remedy to specify — those are drafting questions with real consequences. They belong with a lawyer qualified in Chinese law. Several firms publish detailed material on exactly this, and it is worth reading before you commission anything.

We are a verification desk and never a law firm. Nothing on this page is legal advice, and we do not draft, review or assess agreements.

2. Where it sits in the sequence

The useful thing a buyer can control is timing, and timing is not a legal question.

An NNN agreement belongs before the first detailed drawing, specification, sample or tooling file leaves your side: which in practice means before most of the interesting conversations with a supplier have happened. Buyers routinely reach for one after a supplier has already had the files for a month, at which point it is closing a door on an empty room.

The same logic applies to the whole pre-order stack: an agreement, a trademark filing, and knowing who the counterparty is are all front-loaded steps. Every one of them is cheap before the deposit and expensive or useless afterwards.

3. The part a buyer can settle themselves: who signs

This is where public records do the work, and where most of the avoidable failure sits. Three questions, all answerable before signing.

• Which registered entity is this? Every mainland company carries an 18-character Unified Social Credit Code on its business licence. Company names in China repeat constantly, and the English trading name in your emails may correspond to no registered entity at all. An agreement naming only an English name, or naming a company that does not exist in the register, starts from a weak position. Check the code structure in your browser, then read the live registration record.
• Does this entity actually make anything? The registered business scope distinguishes a manufacturer from a company licensed only to trade. Suppose the signing party is a trading company and the goods are produced by a separate factory. An agreement with the trader does not by itself reach the factory that holds your drawings. That may be perfectly acceptable, but it should be a decision and never a discovery. Read the scope in your browser, free.
• Is the Chinese name exact? A Chinese company is identified by its registered Chinese name. Agreements signed only in English, against a name that does not match the register, create an identification problem before anyone reaches the merits. Get the exact registered characters and put them in the document. How the English sales name, the Chinese legal name and the code form one chain.

None of the three requires a lawyer. All three change what a lawyer can do for you later.

4. Why trademark registration comes up in the same conversation

China operates a first-to-file trademark system: rights generally follow registration rather than prior use in another market. Buyers discover this in an unpleasant way. A mark they have used at home for years is registered in China by someone else, sometimes by a party they were talking to.

The buyer-side action is again about timing, not law: raise it before drawings, brand files and sample packaging start circulating among factories. Which classes to file, how to structure the filing and what to do about an existing conflicting mark are matters for a qualified trademark practitioner.

What we can add from the registry side is narrower and still useful. Knowing exactly which registered entity you have been dealing with, Chinese name and code, is the starting point for any search or any later dispute about who filed what.

What an NNN protects is almost entirely invisible in the public record

What is visible is whether the counterparty has been in court. On 46 ordinary Chinese manufacturers read on 28 August 2026, 37.0% carried at least one published court hearing notice — median three, one company with 52. That says nothing about who was right, and nothing about your agreement. It does say whether litigation is a routine part of how this counterparty operates. Six risk signals measured across 46 manufacturers →

Before relying on a check as a substitute for the agreement, see how little of this the register carries. On 22 August 2026 I queried the intellectual-property and equity-security dimensions for 45 Chinese manufacturers. Every company on the NHTSA vehicle-manufacturer list resolving to one Chinese entity.

Not one of the 45 has pledged intellectual property as security, and that is the closest the register gets to saying anything about IP at all in this run. Whether a supplier holds patents, and whether it is quietly using yours, are different questions that this record does not touch.

The last row is the argument for the agreement. Non-use, non-disclosure and non-circumvention cover drawings, tooling, specifications, formulations and your customer relationships — none of which is a registry field in any jurisdiction. There is no lookup that substitutes for the contract, because the thing at risk was never registered anywhere.

Which is also why the entity naming on the agreement matters more than usual. An NNN signed by a trading company does not bind the factory that receives your drawings, and the register will not warn you about that either.

The order these steps belong in

A workable sequence for a first order with an unfamiliar factory, with the legal steps left to legal professionals:

• Identify the entity: exact Chinese name, 18-character code, registration status, business scope. Public records, minutes of work.
• Handle brand protection: trademark filing considered before files circulate, with a qualified practitioner.
• Put the agreement in place: drafted or reviewed by a China-qualified lawyer, naming the entity you verified in step one.
• Then share the drawings, and only then start the commercial conversation in earnest.

Step one is the part we do. If you want the registration record read by someone in China, with the source named, the query date attached, and the limits stated — that is what this desk is for. Steps two and three need a lawyer, and we do not take that work or refer for commission.

This page describes public records and the order of a sourcing process. It is not legal advice, it is not a substitute for advice from a qualified practitioner of Chinese law. Nothing here should be relied on as an assessment of any agreement or its enforceability.
