  • China NNN Agreement

    Before sending drawings, product concepts, or brand information to any Chinese factory or sourcing agent.

  • PRC-Focused NNN / Supplier Contract Review

    Review what you have for PRC enforceability gaps, missing non-use or non-circumvention terms, and correct contracting party.

  • Product Development + NNN Terms

    Covers sample deliverables, IP ownership of prototype outputs, and restricts factory use of your product concept during development.

  • Tooling Ownership + Manufacturing Terms

    Defines who owns the mold or tooling, controls usage rights, and restricts the factory from using tooling for other buyers.

  • OEM / Manufacturing Agreement

    Full production relationship: quality, delivery, payment, subcontracting, improvements, exclusivity, and brand-use restrictions.

  • Supplier Control Review

    Review of existing exposure, leverage options, and recommended protection steps when a supplier relationship shows signs of risk.

Anonymized Patterns

Common supplier-risk situations we see

Anonymized patterns, not client-specific stories.

Two colleagues reviewing a document at a desk

Case Pattern 1

Exclusivity promised, but not defined

A product brand was preparing to share files with a Chinese manufacturer. The factory agreed to exclusivity, but the scope was not defined in writing.

Risk

Competing buyers, similar products, unclear tooling control.

Protection

NNN + exclusivity + trademark coordination.

Case Pattern 2

Drawings shared before protection

A hardware founder had already shared drawings and samples before asking about contract protection.

Risk

Files already disclosed, unclear ownership, factory-side reuse.

Protection

Supplier-risk review + bilingual agreement + next-step IP filing.

Team members discussing a workflow on a whiteboard

Case Pattern 3

Brand Not Filed Before Manufacturing

A brand planned China manufacturing but did not intend to sell in China, so trademark filing seemed unnecessary.

Risk

Factory, distributor, or third party may file first in China.

Protection

China trademark + NNN + manufacturing terms.

FAQ

Frequently asked questions about China NNN & manufacturing agreements

Practical answers — not law school explanations.

What is a China NNN agreement?

+

A China NNN agreement is designed to address non-disclosure, non-use, and non-circumvention risks when sharing product, supplier, brand, or manufacturing information with a China-side party.

Is a foreign NDA enough for a Chinese supplier?

+

Often not. A China-focused agreement should consider Chinese language terms, China-side enforcement, the correct contracting party, product-file control, tooling, subcontractors, and supplier-side obligations.

When do I need an OEM or manufacturing agreement?

+

An OEM or manufacturing agreement is usually needed when the project moves beyond early disclosure into samples, tooling, production, quality control, delivery terms, improvements, exclusivity, or long-term supplier obligations.

Should I sign the supplier's agreement?

+

A supplier-provided NDA, NNN, PO, PI, or manufacturing agreement should be reviewed before signing because it may not protect your brand, product files, tooling, improvements, payment path, or supplier relationship.

How does this connect with China trademark protection?

+

Contract protection and trademark protection should be coordinated. A China trademark can help protect the brand, while NNN/OEM terms help control disclosure, production, product files, tooling, and supplier-side conduct.

What is the difference between an NDA and a China NNN agreement?

+

A standard NDA (non-disclosure agreement) addresses the obligation not to share information. A China NNN agreement goes further — it addresses non-disclosure, non-use, and non-circumvention as three separate obligations. In Chinese factory relationships, the risk is rarely limited to disclosure. The factory may not share your files externally, but may still use your drawings for a competing product, or work around you to sell direct to your customers. An NNN agreement is specifically structured to address all three risks, and to do so within PRC law rather than a foreign legal framework. See also: NDA vs NNN Agreement comparison at /resources/practical-answers/nda-vs-nnn/

Do I need a China NNN agreement before contacting a factory?

+

In most cases, yes — or at minimum before sharing drawings, samples, technical specifications, or product concepts. Once a factory receives substantive information about your product, your leverage changes. An NNN agreement before first outreach is cleaner and easier to negotiate. If you have already started conversations, a signed NNN before sharing further files is still better than none.

Can a China NNN agreement stop a supplier from selling my product?

+

A well-drafted NNN agreement can include non-use and non-circumvention provisions that restrict the factory from using your product concept, designs, or specifications to produce and sell to third parties, competitors, or downstream channels. It can also include restrictions on displaying your product on platforms like Alibaba or Global Sources without permission. No contract eliminates all risk, but a China-facing NNN with clear restrictions and calibrated liquidated damages creates meaningful deterrence and a legal basis to act if breached.

What is a manufacturer exclusivity agreement in China?

+

A manufacturer exclusivity agreement defines the scope in which a Chinese factory is restricted from producing the same or similar products for other buyers. It typically covers: producing identical or substantially similar products, supplying competitors or related brands, selling direct to the same customer channels, and subcontracting the same product to unapproved parties. Exclusivity clauses can be standalone or combined with an NNN or manufacturing agreement. The scope and enforceability of exclusivity depends heavily on how it is defined — vague exclusivity language often provides very limited protection.

Should my China NNN or manufacturing agreement be in Chinese?

+

For practical enforcement in PRC courts, a Chinese controlling version is generally the stronger structure. Agreements where the English version is stated to control require courts to rely on a translation — which introduces interpretation risk. A Chinese controlling version that is precisely drafted for PRC legal logic — not merely translated from English — is the more defensible approach. Many clients start with English for commercial review, then finalize the Chinese controlling version after revision points are agreed.

When do I need an NNN vs an OEM / manufacturing agreement?

+

An NNN agreement is appropriate for the early stages — outreach, RFQ sharing, drawing review, and first discussions. Once you move into sampling, tooling, and actual production, you need a manufacturing agreement that covers the full production relationship: delivery, quality, tooling ownership, penalties, and brand use restrictions. The two are complementary, not interchangeable.
