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
| Topic | Typical Western NDA | Stronger China manufacturing NNN posture |
|---|---|---|
| Language | English only | Chinese (or bilingual with Chinese controlling) |
| Focus | Confidentiality | Non-use + non-disclosure + non-circumvention |
| Parties | Parent brand | Actual manufacturing entity (+ affiliates if needed) |
| Subcontractors | Often silent | Flow-down + written approval |
| Remedies | Vague equitable relief | Clear breach liquidated damages where enforceable + IP claims |
| Dispute forum | Home court only | PRC court or workable arbitration with assets in mind |
| Term | 2–3 years | Long enough for product life + residual non-use for trade secrets |
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
- Before RFQ / samples: NNN (this page).
- Sampling / pilot: sample order terms; who pays molds; who owns molds.
- Production: manufacturing/OEM agreement—quality, capacity, price mechanism, audit, recall cooperation, IP, liability caps carefully negotiated.
- Brand protection: China trademarks (and designs/patents where strategy fits).
- Exit: mold return, last-time buy, non-use survival, transition stock.

Practical process (one week sprint)
- Day 1: Identify factory legal name from licence; map group companies.
- Day 1–2: Counsel drafts Chinese NNN with project schedule (products, drawings list).
- Day 2–3: Negotiate liquidated damages and subcontracting; avoid hollowing non-use.
- Day 3–4: Execute with chop; exchange scanned + retain originals.
- Day 4+: Release files in stages; log access; only then ship expensive tooling cash.
Common mistakes
- English-only NDA with a US venue against a Dongguan factory that never leaves Guangdong.
- Signing with a trading company while drawings go to an undisclosed sub-factory.
- No non-use clause—only confidentiality—so “we made a similar product ourselves” arguments flourish.
- Sending full CAD pack before any paper because “they need it for a quick quote.”
- Liquidated damages set at absurd numbers with no relation to project value (enforceability risk).
- Forgetting mold ownership—factory holds the steel and the leverage.
- 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.
