NNN Agreements for China Manufacturing: Non-Use, Non-Disclosure, Non-Circumvention

Foreign brands often ask for an “NDA for China factories.” What they usually need is an NNN agreement—non-use, non-disclosure, and non-circumvention—written for PRC manufacturing reality, in Chinese, with teeth. This guide explains when NNN matters, what to put in it, how it differs from a Western NDA, and how it links to tooling, samples, and supply contracts.

Business question first

“Will the factory copy my product, sell to my customers, or use my drawings for someone else?”

A US/UK-style NDA that only says “keep secrets confidential,” governed by Delaware law, served only in English, with vague damages, is a weak answer for that question. An NNN package aims to:

  • Non-use — factory cannot use your specs/drawings to make for others (or itself) outside the project.
  • Non-disclosure — factory cannot share your information with third parties (including sub-suppliers without control).
  • Non-circumvention — factory cannot bypass you to sell to your customers or sources you introduced.

NNN is not a substitute for trademarks, design patents, or careful supplier selection—but it is often the first legal control when you send a CAD file or sample brief.

When to use an NNN (and when it is not enough)

Use NNN early when you will:

  • Send drawings, BOMs, firmware, or tooling concepts to a Chinese manufacturer for quote or sample.
  • Run multi-factory RFQs and fear cross-shop leakage.
  • Introduce a brand-side customer list or retail channel to a factory or trading company.

NNN alone is not enough when you need:

  • Long-term production → full manufacturing / OEM / quality agreement with forecasts, QC, IP ownership, audit rights.
  • Registered brand protection → trademark first-to-file strategy in China.
  • Employee-side leakage → labour + trade-secret program, not only factory paper. See first employee roadmap if you hire local staff.

Western NDA vs China-oriented NNN

TopicTypical Western NDAStronger China manufacturing NNN posture
LanguageEnglish onlyChinese (or bilingual with Chinese controlling)

SubcontractorsOften silentFlow-down + written approval
RemediesVague equitable reliefClear breach liquidated damages where enforceable + IP claims
Dispute forumHome court onlyPRC court or workable arbitration with assets in mind

Core clause checklist

  • [ ] Parties — correct Chinese company name (business licence), unified social credit code; chop authority
  • [ ] Purpose — limited to quotation / sampling / named project
  • [ ] Definition of confidential information — drawings, tooling, pricing, customer IDs, firmware, molds
  • [ ] Non-use — no production for third parties using your info; no reverse-engineering beyond agreed analysis
  • [ ] Non-disclosure — need-to-know; no public showrooms with your unreleased SKU
  • [ ] Non-circumvention — customers, suppliers, and agents you introduce
  • [ ] Subcontracting — ban or written consent + flow-down NNN
  • [ ] Return/destruction of samples, files, molds on request
  • [ ] Ownership of improvements / tooling — who owns molds and derivative designs
  • [ ] Term & survival — confidentiality survival after project ends
  • [ ] Remedies — liquidated damages carefully drafted; injunction language; evidence cooperation
  • [ ] Governing law & dispute resolution — aligned with where the factory’s assets and management sit
  • [ ] Language — Chinese controlling version executed with company chop

Enforcement reality (plain language)

  • Paper quality matters: Chinese text, correct party, chop, and specific product descriptions beat a generic English NDA.
  • Evidence matters: watermark files, access logs, sample logs, WeChat/email trails, mold ownership records.
  • Asset location matters: a judgment or award is useful if the counterparty has attachable assets or cares about export customers.
  • Trade secret law + Anti-Unfair Competition Law can support claims beyond contract—see trade secrets framework.
  • Criminal thresholds exist for serious trade-secret theft—but do not plan a commercial program around rare criminal cases.

NNN is one layer of a supplier risk program: due diligence, dual sourcing for critical SKUs, controlled file release, and IP registration.

How NNN sits in the contract stack

  1. Before RFQ / samples: NNN (this page).
  2. Sampling / pilot: sample order terms; who pays molds; who owns molds.
  3. Production: manufacturing/OEM agreement—quality, capacity, price mechanism, audit, recall cooperation, IP, liability caps carefully negotiated.
  4. Brand protection: China trademarks (and designs/patents where strategy fits).
  5. Exit: mold return, last-time buy, non-use survival, transition stock.

Practical process (one week sprint)

  1. Day 1: Identify factory legal name from licence; map group companies.
  2. Day 1–2: Counsel drafts Chinese NNN with project schedule (products, drawings list).
  3. Day 2–3: Negotiate liquidated damages and subcontracting; avoid hollowing non-use.
  4. Day 3–4: Execute with chop; exchange scanned + retain originals.
  5. Day 4+: Release files in stages; log access; only then ship expensive tooling cash.

Common mistakes

  1. English-only NDA with a US venue against a Dongguan factory that never leaves Guangdong.
  2. Signing with a trading company while drawings go to an undisclosed sub-factory.
  3. No non-use clause—only confidentiality—so “we made a similar product ourselves” arguments flourish.
  4. Sending full CAD pack before any paper because “they need it for a quick quote.”
  5. Liquidated damages set at absurd numbers with no relation to project value (enforceability risk).
  6. Forgetting mold ownership—factory holds the steel and the leverage.
  7. No trademark filing while arguing about drawings—the brand still gets squatted.

FAQ

Is NNN a Chinese legal term of art?
It is industry shorthand popularised in cross-border manufacturing practice. PRC courts care about the actual rights and obligations in the Chinese contract and applicable IP/unfair competition law—not the marketing label “NNN.”

Can we use one master NNN for all factories?
Yes as a template; still execute per counterparty with correct names and project schedules.

Does NNN replace patents?
No. Patents/designs/trademarks are registration rights. NNN is contractual + trade-secret hygiene.

What if the factory refuses to sign?
Treat refusal as a diligence signal. Tighten file release, use coarser drawings for quote stage, or walk away.
