NNN Agreements and IP Protection in China

By ChinaManufacturers.com Editorial Desk · Updated 30 October 2026 · How this page was researched

What an NNN agreement is

An NNN agreement is a non-disclosure, non-use and non-circumvention contract written for Chinese manufacturers: it bars the factory from disclosing the buyer's design, from using it to make goods for itself or anyone else, and from going around the buyer to sell to the buyer's customers. A conventional US-style NDA (non-disclosure agreement) usually covers only the first of those three promises.

The difference reflects the real risk. A factory that makes a product does not need to leak the design to cause harm; it can simply make more units and sell them, or approach the buyer's customers directly. A disclosure-only NDA does not reach that conduct. "NNN" is a practitioner term, not a statutory one — no official Chinese government source defining it was found — so what the agreement covers depends entirely on its text.

An NNN is a contract. It binds the party that signs it, and it is enforced as a contract claim. That distinguishes it from registered intellectual property — a trademark or design patent recorded with China's national IP office — which is a property right enforceable against anyone. Both matter, and the sequencing between them is the core of IP protection in China.

Why China calls for a different instrument

China's trademark system is first-to-file: rights go to the first applicant to register a mark, not to the first business to use it. A foreign brand that has not filed in China can find its mark registered by a third party, including its own supplier or distributor. (The specific articles of the PRC Trademark Law on prior registration and bad-faith filing were not re-read for this guide.)

The official US framing comes from the Office of the United States Trade Representative (USTR). Its 2026 Special 301 Report, issued in April 2026, states that "China remains on the Priority Watch List in 2026 and is subject to continuing monitoring pursuant to Section 306 of the Trade Act of 1974" (p. 50) and that "bad faith trademarks remain one of the most significant challenges for U.S. brand owners in China" (p. 58). The same report names Vietnam a Priority Foreign Country, the most serious category, which is relevant to buyers moving production there.

USTR records two recent developments in the trademark system. Stakeholders reported a 2025 shift at the China National Intellectual Property Administration (CNIPA) "toward stricter examination standards" without an official announcement, which "reportedly increased the evidentiary burden on legitimate trademark holders and even resulted in preliminary refusals of legitimate trademark applications" (p. 58). And in December 2025 the National People's Congress (NPC), China's national legislature, released a draft Trademark Law amendment with "improved tools to address bad faith trademarks" that, in USTR's assessment, "still falls short" on civil remedies and on deterring repeat bad-faith filers (pp. 57–58).

How NNN agreements are usually drafted

Practitioner consensus — not an official rule — is that an NNN agreement intended for use against a Chinese factory is written so that a Chinese court can enforce it quickly. That usually means:

Chinese language, or a bilingual text in which the Chinese version controls.
PRC governing law, so the court applies its own law rather than proving a foreign one.
Jurisdiction in the supplier's local Chinese court, where the factory and its assets are.
A stated liquidated-damages amount, so the buyer does not have to prove its loss from scratch.
The factory's full registered Chinese name and its Unified Social Credit Code as the contracting party.
A defined scope of the products, drawings, molds and information covered.

The logic is that a US court judgment is hard to enforce in China, so an agreement that sends disputes to a US court can leave the buyer with a judgment it cannot collect. A trade attorney familiar with Chinese practice should draft or review the text; this guide describes the structure, not the wording.

Enforcement in Chinese courts: what USTR records

An NNN is enforceable as a contract under PRC law in a Chinese court. No official statistic on outcomes of NNN or other contract-based IP suits by foreign plaintiffs was found. What is documented are the obstacles. In the 2026 Special 301 Report, USTR records that stakeholders face "high evidentiary burdens, limited discovery, difficulties meeting stringent conditions to enforce agreements related to protection of trade secrets and confidential business information against theft, and difficulties in obtaining deterrent-level damages awards" (p. 51).

Several dated changes bear on enforcement, as reported by USTR:

November 2023 — the Apostille Convention entered into force for China, simplifying authentication of foreign documents, though USTR describes implementation as "inconsistent" (p. 57).
January 2024 — Civil Procedure Law amendments expanded Chinese courts' jurisdiction over cases involving foreign parties (p. 57).
March 2025 — the State Council issued Provisions on the Handling of Foreign-Related Intellectual Property Disputes, which USTR calls "a troubling measure that seemingly legitimizes political intervention in IP disputes" (p. 58).
15 October 2025 — the amended Anti-Unfair Competition Law, issued in June 2025, entered into force without raising administrative penalties for trade-secret misappropriation (pp. 51, 57–58).

USTR also notes that Chinese courts publish only selected decisions and that uploads have "consistently decreased over the past five years" (p. 57), which makes outcomes harder to research. The cumulative point is that a contract claim in China is slower and less certain than a claim based on a registered right, which is why an NNN should accompany registration rather than replace it.

Register trademarks and designs before sharing

Registration with CNIPA does what a contract cannot: it gives the brand owner a right against anyone, including parties that never signed anything. The scale of the register shows how routine this is. CNIPA's 2025 statistical tables report:

CNIPA measure, 2025	2025	2024
Trademark applications (all origins)	6,952,550	6,970,559
Trademark registrations (all origins)	4,205,797	4,780,731
Trademark applications from US-origin applicants	40,944	35,399
Trademark registrations to US-origin applicants	25,284	27,711
US-origin marks in force at year-end	483,151	469,418
Design patents granted (all origins)	666,245	643,318

Sources: CNIPA 2025 Statistical Annual Report, Tables 7-1 and 7-3 (trademarks, counted by applicant's country of origin, covering all US filers rather than only importers) and Table 2-1 (patents). Foreign-origin trademark registrations in 2025 were 122,451, and foreign-origin design grants were 18,020. The fall in total registrations is consistent with the stricter examination USTR describes.

A design patent registered with CNIPA protects a product's appearance. China acceded to the Hague Agreement on international design registration in 2022, and USTR describes the Patent Law Implementing Regulations in force from January 2024 as clarifying the link between international and domestic design procedures (p. 56). China's customs authority, the General Administration of Customs (GACC), also accepts recordal of IP rights to stop infringing exports; its procedure and fees were not verified for this guide.

The scale of the counterfeit problem at the US border

US Customs and Border Protection (CBP) reports in its FY2025 IPR seizure statistics that FY2025 IPR seizures totaled 78.4 million items with a manufacturer's suggested retail price (MSRP) of $7.4 billion, up from 32.3 million items and $5.4 billion in FY2024. China (about $5.16 billion MSRP) and Hong Kong (about $1.28 billion) were the top two sources by value, and together accounted for "approximately 67% of the total quantity" seized. USTR, citing the CBP dashboard as of 1 April 2026, puts China and Hong Kong at over 87% of seized value in FY2025, consistent with the CBP figures.

Read these numbers with their limits. Value share (about 87%) and quantity share (about 67%) measure different things. MSRP values seized goods as if they were genuine, not at their actual worth. CBP states the publication is not official trade statistics, and the copy used for this guide was read from an archived version after cbp.gov blocked automated download. For FY2024, CBP's text gives China and Hong Kong "approximately 90%" of quantity seized, while its own country table sums to about 86% — a small internal inconsistency in the source. Vietnam was the second-largest source by quantity in FY2025, with 22,910,860 items.

Globally, USTR cites OECD–EUIPO research putting trade in counterfeit and pirated goods at $467 billion in 2021, 2.3% of world imports; those underlying studies were not read directly. For a brand owner, the takeaway is that counterfeit enforcement now reaches containerized imports — 62% of FY2025 seizures were in commercial-vessel cargo, per CBP — and that a factory with the buyer's files is an obvious place for an unauthorized production run to start.

Common mistakes

Filing a trademark only in the United States. A US registration does not protect the brand in China's first-to-file system.
Using a US-law NDA with US court jurisdiction. It covers disclosure only and produces a judgment that is hard to enforce in China.
Treating an NNN as a substitute for registration. A contract binds the signer; a registered trademark or design binds everyone.
Sending full technical files before any agreement or registration. The order of steps is the protection.
Signing with a trade name rather than the registered Chinese entity. A contract against the wrong party is hard to enforce against anyone.

Frequently asked questions

What is an NNN agreement?

An NNN agreement is a non-disclosure, non-use and non-circumvention contract written for Chinese manufacturers. It prohibits the factory from revealing the buyer's design, from using it to make goods for itself or others, and from bypassing the buyer to sell to its customers. NNN is a practitioner term, not a statutory one, so the text defines its scope.

What is the difference between an NNN and an NDA?

An NDA usually covers disclosure only. An NNN adds non-use, which stops the factory making the product for itself or others, and non-circumvention, which stops it dealing directly with the buyer's customers. NNNs for China are typically drafted in Chinese under PRC law with local Chinese court jurisdiction, because US judgments are hard to enforce there.

Is an NNN agreement enforceable in China?

Yes, as a contract under PRC law in a Chinese court, but enforcement is subject to the obstacles USTR documents: high evidentiary burdens, limited discovery and difficulty obtaining deterrent-level damages. No official statistic on NNN case outcomes was found. That is why an NNN should accompany trademark and design registration rather than replace it.

Is China still on the US Priority Watch List?

Yes. USTR's 2026 Special 301 Report, issued in April 2026, states that China remains on the Priority Watch List and is subject to continuing monitoring under Section 306 of the Trade Act of 1974. The same report identifies Vietnam as a Priority Foreign Country, the most serious category in the review.

Do I need to register my trademark in China?

A brand that will be manufactured or sold in China has strong reasons to register there, because China's system is first-to-file and a US registration does not protect the mark in China. USTR calls bad-faith trademarks one of the most significant challenges for US brand owners in China. US-origin applicants filed 40,944 Chinese trademark applications in 2025, per CNIPA.

How much of the counterfeit merchandise seized by CBP comes from China?

In FY2025, China and Hong Kong accounted for over 87% of the MSRP value of IPR goods seized by CBP and about 67% of the quantity. In FY2024 the shares were over 93% of value and about 90% of quantity. Value and quantity shares differ, and MSRP prices seized goods as if they were genuine.

Does China protect product designs?

Yes, through design patents registered with the China National Intellectual Property Administration, which protect a product's appearance. CNIPA granted 666,245 design patents in 2025, of which 18,020 went to foreign-origin applicants. China joined the Hague Agreement on international design registration in 2022, giving foreign applicants an international filing route.
