Key Takeaways
Without explicit mold ownership and IP assignment clauses, Chinese law defaults to the manufacturer owning your tooling and designs. A bilingual OEM contract written under PRC law is the only enforceable protection. The seven clauses covered in this guide — mold/tooling ownership, IP assignment, quality with inspection rights, payment milestones, PRC jurisdiction, termination/exit, and NNN integration — are not optional. Each omission creates a specific, predictable legal risk that Chinese courts cannot remedy without a contractual basis.
Why OEM Contracts Are Different — and Higher Risk
A standard supplier contract for off-the-shelf goods involves a transaction: money for products. An OEM (Original Equipment Manufacturing) contract involves a relationship: you provide designs, specifications, tooling investment, and proprietary information. The manufacturer receives not just your money but your intellectual property, your production processes, and — critically — physical assets (molds, dies, tooling) that represent months of development and thousands of dollars of investment.
Under Chinese law, the default position for each of these is unfavorable to the buyer:
- Molds and tooling: Default ownership is with the party who paid for and possesses them — typically the manufacturer.
- Designs and IP: Default ownership is with the creator — the manufacturer who physically produced the goods, not the buyer who provided the concept.
- Quality: In the absence of contractual specifications, the applicable standard is the Chinese national standard (GB standard), which may be far below your market's requirements.
- Dispute resolution: Without a jurisdiction clause, disputes default to the defendant's location — the manufacturer's local court.
Every clause in this guide reverses one of these defaults. Together, they shift the legal balance from the manufacturer (where Chinese law places it by default) to the buyer (where it should be, given that the buyer is funding the entire operation).
The 7-Clause OEM Contract Checklist
OEM Contract Clause Checklist
- Clause 1: Mold and Tooling Ownership — who owns the physical production assets
- Clause 2: Intellectual Property Assignment — who owns the designs, specifications, and outputs
- Clause 3: Quality Standards, Inspection, and Acceptance — what standard the goods must meet
- Clause 4: Payment Milestones and Conditions — when money is released and under what conditions
- Clause 5: Governing Law and Jurisdiction — which court decides disputes and under which law
- Clause 6: Termination Rights and Exit Provisions — how to end the relationship and retrieve your assets
- Clause 7: NNN Agreement Integration — incorporating non-disclosure, non-use, non-circumvention
Clause 1: Mold and Tooling Ownership
Default under Chinese law: The manufacturer owns the molds and tooling it paid for and possesses, regardless of who funded their development through the unit price.
This is the most expensive single omission in China OEM contracts. A mold for plastic injection manufacturing costs $5,000-$50,000 depending on complexity. You pay for it — embedded in your per-unit price, a separate line item, or an upfront tooling charge — and assume it belongs to you. Under Chinese law without a contractual clause stating otherwise, it does not.
What the clause must cover:
Express ownership declaration
"All molds, dies, tooling, fixtures, and jigs (collectively 'Tooling') created or acquired for the production of the Products shall be the sole and exclusive property of the Buyer, regardless of which party paid for or possesses the Tooling."
Manufacturer's duty of care
"The Manufacturer shall maintain the Tooling in good working condition, insure it against loss or damage, and shall not use the Tooling for any purpose other than producing Products for the Buyer without the Buyer's prior written consent."
Return upon termination
"Upon termination of this Agreement for any reason, the Manufacturer shall, within 15 days, return all Tooling to the Buyer at the Buyer's direction and cost, or destroy the Tooling and provide a certificate of destruction."
Labeling requirement
"The Manufacturer shall affix a permanent label to each mold and die identifying it as 'Property of [Buyer Name] — Not for Use Outside Contract [Contract Number].'" — This creates physical evidence of ownership for enforcement purposes.
Mold Ownership Red Flags in Supplier Contracts
- The contract says "tooling cost included in unit price" but does not state who owns the tooling
- The supplier claims "we always own the molds — it's standard practice in China"
- The supplier refuses to allow mold labeling because it "interferes with production"
- No provision for mold return or destruction upon contract termination
Clause 2: Intellectual Property Assignment
Default under Chinese law: IP rights in a manufactured product belong to the creator — the manufacturer — unless explicitly assigned in writing.
This is the second most expensive omission. You spend months developing a product design, technical specifications, packaging, and branding. You send these to a Chinese manufacturer with a purchase order. You receive finished goods. Under Chinese law, unless your contract includes an IP assignment clause, the manufacturer may claim ownership of:
- Any improvements or modifications made to your design during production
- Any manufacturing processes developed to produce your product
- Any derivative works based on your specifications
- The right to produce identical or substantially similar products for other buyers — including your competitors
What the IP assignment clause must cover:
| IP Element | What the Clause Must State | Why It Matters |
|---|---|---|
| Pre-existing IP | All designs, specifications, and technical information provided by Buyer remain Buyer's exclusive property | Prevents the supplier from claiming you abandoned your IP by sharing it |
| Work product | All products, prototypes, tooling designs, and production outputs created under the contract are "works made for hire" owned by Buyer | The "work made for hire" concept does not exist in Chinese law — it must be created by contract |
| Improvements | Any improvements, modifications, or derivative works to Buyer's IP made by Manufacturer are automatically assigned to Buyer | Without this, the manufacturer owns any production improvements they develop |
| Moral rights waiver | Manufacturer waives any moral rights (authorship rights) to the extent permitted under PRC law | Chinese copyright law recognizes moral rights that cannot be assigned — they can only be waived |
| Post-termination | Manufacturer shall not use, reproduce, or retain any Buyer IP after contract termination | Prevents the "we still had the files on our server" defense |
The IP assignment clause should reference China's specific IP laws: the PRC Patent Law (专利法), PRC Copyright Law (著作权法), and PRC Anti-Unfair Competition Law (反不正当竞争法) — this signals to a Chinese judge that the clause was drafted with Chinese law in mind and should be interpreted under Chinese legal principles.
Clause 3: Quality Standards, Inspection Rights, and Acceptance
Default under Chinese law: If a contract specifies no quality standard, the default is the applicable Chinese national standard (GB/T standard) — or, if none exists, a vaguely defined "reasonable quality" standard that Chinese judges interpret narrowly.
Your market may require products meeting UL, CE, FDA, or ASTM standards. Unless these are specified in the contract, the manufacturer's obligation is to meet the Chinese standard — which may be completely different. This is how manufacturers deliver "legally conforming" goods that are unsellable in your market.
What the quality clause must include:
- Detailed product specifications: Attach as an appendix with dimensions, materials, tolerances, colors (Pantone codes), and performance criteria — all in measurable, objective terms. "High quality" is not a specification a Chinese court can enforce.
- Applicable standards: List every standard the product must meet: UL, CE, FDA, ASTM, ISO, RoHS, REACH, etc.
- Pre-production sample approval: The manufacturer must produce and the buyer must approve a pre-production sample before mass production begins. The approved sample becomes the reference standard.
- Inspection rights: Buyer (or a designated third-party inspector such as SGS, TUV, or Intertek) has the right to inspect: raw materials before production, in-process production at any stage, finished goods before shipment. Inspection results are binding.
- Acceptance criteria: Define what constitutes acceptable quality: typically no more than X% defective units per batch (AQL standard — Acceptable Quality Level, commonly AQL 2.5 for major defects and AQL 0 for critical defects).
- Rejection and remedy: If goods fail inspection, the manufacturer must rework or replace within X days at its own cost. If rework/replacement fails, the buyer may cancel the order with full refund including tooling costs.
Clause 4: Payment Milestones and Conditions
Default under Chinese law: Payment terms are as stated in the contract. If payment is specified as "50% deposit, 50% before shipment," the manufacturer can demand the second 50% before any inspection has occurred.
A well-structured payment clause ties each payment to a verifiable milestone, not a date on the calendar.
| Payment | Triggering Condition | Purpose |
|---|---|---|
| 30% Deposit | Upon signing of contract and receipt of proforma invoice | Covers raw material procurement; manufacturer has skin in the game |
| 30% Production Milestone | Upon buyer's confirmation (in writing) that pre-production samples meet specifications, AND receipt of photo/video evidence that mass production has commenced | Ensures production began before releasing more funds |
| 40% Final Payment | Upon: (i) successful third-party pre-shipment inspection, (ii) receipt of copy of bill of lading, AND (iii) receipt of all required export documentation | Last payment is released only when goods are verified and shipped |
This 30/30/40 structure keeps the manufacturer's unpaid work proportionate to your unrecovered payment at every stage. If the manufacturer walks away after receiving the deposit, you have lost 30% — not 50% or 100%. If the manufacturer fails inspection, the remaining 70% gives you leverage to demand rework or refund.
The clause must also specify that "payment shall be made only to the Manufacturer's corporate bank account in the name of [Manufacturer's Registered Company Name] — no payment to personal accounts, third-party accounts, or offshore accounts shall constitute valid payment under this Agreement." This closes the most common shell company payment route.
Clause 5: Governing Law and Jurisdiction
Default under Chinese law: If the contract is silent, disputes are governed by the law of the jurisdiction with the closest connection to the contract — which, for a contract performed by a Chinese manufacturer in China, means PRC law applied by the court in the manufacturer's location.
This is one of the rare areas where the default is actually acceptable for the buyer — PRC law in a Chinese court — but only if you specify it explicitly. Leaving it to default creates jurisdictional uncertainty that the manufacturer will exploit to delay proceedings.
What the jurisdiction clause should state:
Governing law
"This Agreement shall be governed by and construed in accordance with the laws of the People's Republic of China." Do not specify foreign law. Chinese courts will not apply it, and the attempt only creates a preliminary jurisdictional fight.
Dispute resolution venue
"Any dispute arising from or in connection with this Agreement shall be submitted to [CIETAC South China Sub-Commission in Shenzhen / the Intermediate People's Court in [Supplier's City]]." CIETAC arbitration is generally faster than court litigation (6-12 months vs 12-24 months) but costs more upfront. Court litigation has lower upfront costs but longer timeline. For contracts under $100,000, court is usually more cost-effective; above $100,000, CIETAC becomes more attractive.
Language
"This Agreement is executed in both Chinese and English. In the event of any discrepancy, the Chinese version shall prevail." This eliminates translation disputes in litigation — the judge reads the Chinese version directly.
Clause 6: Termination Rights and Exit Provisions
Default under Chinese law: A contract may be terminated only by mutual agreement or by a material breach that makes continued performance impossible. Without specified termination rights, you may be locked into a failing relationship with no legal exit.
A strong termination clause covers three scenarios:
- Termination for cause (immediate): The manufacturer commits a material breach — non-delivery, consistent quality failures, IP infringement, insolvency, or enforcement actions. The buyer may terminate immediately upon written notice and is entitled to: full refund of all payments made, return of all tooling and materials, and liquidated damages as specified in the penalty clause.
- Termination for convenience (with notice): The buyer may terminate without cause by giving 30-60 days written notice. The manufacturer is entitled to: payment for work completed and accepted up to the termination date, and return of all tooling, materials, and IP to the buyer. This is important — markets change, products are discontinued. The buyer must be able to exit without being in breach.
- Post-termination obligations: Upon termination, the manufacturer must: immediately cease all production, return all tooling, materials, and IP within 15 days, deliver all completed goods (for which payment has been made), and provide a written certification that all buyer IP has been deleted from its systems and returned.
Clause 7: NNN Agreement Integration
An NNN agreement — Non-Disclosure, Non-Use, Non-Circumvention — is a standalone document that protects information shared during the pre-contract negotiation phase. It should be integrated into the OEM contract, not left as a separate document that may or may not be enforced together.
NTegration method:
- The OEM contract should reference the NNN agreement explicitly: "The NNN Agreement dated [Date] between the Parties is incorporated by reference into this Agreement as Appendix [X] and shall survive the termination of this Agreement."
- The OEM contract's IP clause should complement the NNN: the NNN covers information disclosed; the IP clause covers IP created under the contract.
- The NNN should specify its survival period: typically 5-10 years after contract termination for trade secrets, perpetual for truly confidential information (customer lists, pricing models).

How These 7 Clauses Work Together
These clauses are not independent — they form an integrated protection system. Here is how they interact in the most common dispute scenarios:
| Dispute Scenario | Clauses That Apply | What Happens Without Them |
|---|---|---|
| Manufacturer holds your mold and refuses to release it | Clause 1 (Mold Ownership) + Clause 6 (Termination) + Clause 5 (Jurisdiction) | No legal basis to demand mold return. Manufacturer can use your mold for other buyers. |
| Manufacturer produces your design for a competitor | Clause 2 (IP Assignment) + Clause 7 (NNN) + Clause 5 (Jurisdiction) | No contractual IP protection. Must rely on Chinese IP law alone — slower and narrower. |
| Goods fail quality inspection but manufacturer demands payment | Clause 3 (Quality) + Clause 4 (Payment Milestones) + Clause 6 (Termination) | Manufacturer can claim goods are acceptable because no quality standard was specified. |
| Manufacturer becomes insolvent mid-production | Clause 6 (Termination) + Clause 1 (Mold) + Clause 4 (Payment) | Your materials and tooling may be seized by the manufacturer's other creditors. |
Frequently Asked Questions
Professional bilingual OEM contract drafting by a PRC-licensed lawyer typically costs $1,500-$3,000 for a comprehensive contract with all seven clauses plus appendices. This is approximately 1.5-3% of a $100,000 OEM order. Compare this to the cost of: losing a $15,000 mold ($15,000 + redevelopment time), having your design produced for a competitor (lost market exclusivity), or a failed quality batch that cannot be sold in your market (total loss of order + customer compensation). Our Complete Contract Drafting ($1,999) covers all seven clauses with your specific product and transaction details.
Yes, the 7 core clauses apply to any OEM relationship. Product-specific details — specifications, pricing, quantities, delivery schedules — should be in appendices or separate purchase orders issued under the master OEM agreement. The master agreement contains Clauses 1-7 (ownership, IP, quality framework, jurisdiction, etc.) and remains in effect across all transactions. Each new order references the master agreement and attaches product-specific details. This is the most efficient structure for ongoing OEM relationships.
A manufacturer who refuses to sign a formal contract for an OEM order — where you are providing designs, specifications, and paying for tooling — is sending a clear signal about how they intend to handle disputes. Legitimate manufacturers sign contracts. Those who refuse typically fall into three categories: (1) they intend to keep the IP rights and tooling regardless of the relationship, (2) they are trading companies, not manufacturers, and a contract would reveal this, or (3) they are planning a short-term engagement and see contracts as unnecessary overhead. In all three cases, walk away. The cost of finding another supplier is far less than the cost of an unenforceable OEM relationship.
No. Under PRC law, a contract signed and chopped by both parties is fully enforceable without notarization or registration. Notarization provides an additional layer of evidence — the notary confirms the identities of the signatories and the authenticity of the chops — which can be useful if the manufacturer later claims they did not sign the contract. For orders above $50,000, we generally recommend notarization (additional cost approximately $200-400) as inexpensive insurance against authenticity challenges. Registration is only required for certain specific contract types (real estate, technology import/export, secured transactions) and does not apply to standard OEM manufacturing agreements.
