Key Takeaways
A purchase order written in English is NOT a legally enforceable contract in a Chinese court — at least not in any practical sense. Chinese judges require bilingual documents with specific jurisdiction clauses. A proforma invoice is a commercial document, not a contract — it confirms what you are buying but provides zero legal protection if the supplier fails to deliver. A properly drafted bilingual contract with PRC law governing and Chinese court jurisdiction is the only document that gives you enforceable rights in China.
PO, PI, and Contract: What Each Document Actually Does
Before diving into legal analysis, here is what these three documents mean in practice — and what they do not mean.
📄 Purchase Order (PO)
- What it is: A buyer-issued document listing goods, quantities, prices, and delivery dates
- Legal status in China: An offer — can form a contract if accepted by the supplier, but only for what is written in it
- What it does NOT include: Quality standards, acceptance criteria, penalty clauses, IP protection, governing law, jurisdiction, dispute resolution
- What a Chinese court can enforce based on a PO: Payment for goods delivered (the supplier's claim against you). Almost nothing else.
🧾 Proforma Invoice (PI)
- What it is: A supplier-issued commercial document confirming the goods, quantity, price, and payment terms
- Legal status in China: An invoice — evidence that a transaction exists, but not a contract governing that transaction
- What it does NOT include: Same gaps as a PO — no quality specs, no penalty provisions, no jurisdiction, no IP terms
- What a Chinese court can enforce based on a PI: The supplier can enforce payment. You as the buyer have almost no enforceable rights.
📝 Formal Contract
- What it is: A signed bilateral agreement governing the entire transaction
- Legal status in China: A contract under the PRC Civil Code — the governing document for all rights and obligations
- What it includes: Quality specifications, inspection/acceptance standards, penalty/liquidated damages, IP assignment, confidentiality, governing law, jurisdiction, termination clauses
- What a Chinese court can enforce: Everything — if the contract is bilingual and specifies PRC law jurisdiction
Why English-Language POs Are Unenforceable in Chinese Courts
Under Article 469 of the PRC Civil Code (民法典), a contract can be formed through an offer and acceptance — including through a purchase order. In theory, your English-language PO is a valid contract.
In practice, enforcing an English-language PO in a Chinese court encounters three insurmountable obstacles:
1. Translation Requirement
Chinese courts conduct proceedings exclusively in Chinese. Every document submitted as evidence — including your PO — must be translated into Chinese by a court-certified translation agency. This is not optional and adds significant cost. A 5-page PO with terms and conditions can cost $500-$1,500 to translate and certify. More importantly, the translation itself becomes a point of dispute — the supplier will argue that certain English terms were mistranslated, and the judge has no way to independently verify.
2. Missing Essential Terms
Under PRC contract law, a valid sales contract must include: parties, subject matter (goods), quantity, and price. A standard PO includes these. But for enforcement — for the court to order specific performance or award damages — the contract must include the terms the court needs to determine whether a breach occurred and what the remedy should be:
- Quality standards: What specifications must the goods meet? Without this, the court applies the "national standard" (国家标准) which may be far below what you ordered.
- Inspection and acceptance criteria: When and how are goods deemed accepted? Without this, the supplier can argue you accepted the goods by taking delivery.
- Penalty/liquidated damages: What is the remedy for late delivery or non-conforming goods? Without a contractual penalty clause, you must prove actual damages — which is time-consuming and expensive.
- Governing law and jurisdiction: Which court has authority and which law applies? Without this, you face a jurisdictional fight before the merits are even heard.
Your PO has none of these terms. A Chinese court faced with an English PO will have almost no framework for resolving your dispute — and the judge's default in the absence of contractual guidance is to rule narrowly, typically limiting recovery to the purchase price paid rather than consequential damages like lost profits, customer compensation, or brand damage.
3. Interpretation Risk
Chinese judges apply Chinese legal principles to contract interpretation, not common law principles. Here is what that means in practice:
| English Contract Term | Common Law Meaning | How a Chinese Judge Interprets It |
|---|---|---|
| "Reasonable efforts" | What a prudent person in the same circumstances would do | Vague — judge will define "reasonable" based on Chinese commercial practice, which may be minimal |
| "Material breach" | A breach that goes to the root of the contract, depriving the innocent party of substantially the whole benefit | Judge considers whether the breach is "fundamental" (根本违约) under Article 563 of the PRC Civil Code — a different standard |
| "Time is of the essence" | Any delay, however small, constitutes a breach | Not a recognized concept in Chinese contract law; judge will determine whether the delay was "unreasonable" under the circumstances |
| "Consequential damages" | Damages that flow naturally from the breach but are not direct losses | Chinese law recognizes direct losses (实际损失) but consequential damages are limited to what was "foreseeable at contract formation" under Article 584 — a stricter standard |
What a Proforma Invoice Is — and What It Is Not
A proforma invoice (形式发票) is a commercial document, not a contract. It serves three purposes:
- It confirms the goods, quantity, price, and payment terms the supplier is offering
- It is used by the buyer for import documentation, customs clearance, and letter of credit applications
- It may serve as evidence that a transaction exists, but it does not govern the terms of that transaction
Chinese courts treat a PI as an offer (要约) from the supplier. If you pay based on the PI, you have accepted the offer and a contract is formed — but the "contract" consists only of what is written on the PI. And what is written on a PI is: product description, quantity, unit price, total amount, payment terms (typically "30% deposit, 70% before shipment"), and delivery terms (Incoterms like FOB or CIF).
What is missing from every standard PI: any mention of quality, inspection rights, rejection rights, penalty for late delivery, IP assignment, confidentiality, governing law, or dispute resolution.
If your transaction goes wrong and the only document you have is a PI, here is what happens in a Chinese court:
- Non-delivery: You can sue for return of the deposit. This is the best-case scenario with a PI — and even this takes 6-12 months.
- Defective goods: You cannot sue based on the PI alone because the PI contains no quality specifications. The court will ask: "What standard did the supplier breach?" If the PI does not specify quality, the supplier has not breached any contractual obligation regarding quality.
- IP theft: The PI contains no IP terms. You have no contractual basis to sue for IP infringement.
- Late delivery: The PI contains no penalty clause. You can claim actual damages, but proving them to the court's satisfaction is expensive and uncertain.
PI-Only Transaction Red Flags
- Supplier insists "we only work with PI — no need for a formal contract"
- PI is in English only, no Chinese version exists
- PI has no quality specifications beyond the product name
- PI has no governing law or jurisdiction clause
- Order value exceeds $10,000 and the only document is a PI
What a Bilingual Contract Must Include to Be Enforceable
A properly drafted China supplier contract does not need to be 50 pages. It needs to be in both Chinese and English, with specific clauses covering the issues a Chinese judge will look for when a dispute arises.
Governing law: PRC law
Do not specify US, UK, Australian, or any other foreign law. A Chinese court will not apply foreign law to a dispute with a Chinese company concerning goods manufactured in China. Specifying PRC law is not a concession — it is the only law a Chinese court will apply. Trying to specify foreign law only creates a jurisdictional fight that delays your case and increases costs.
Dispute resolution venue: Chinese court or CIETAC
Specify the Intermediate People's Court in the supplier's city or CIETAC (China International Economic and Trade Arbitration Commission) arbitration. A judgment from a Chinese court is immediately enforceable against the supplier's assets in China. A judgment from a foreign court must go through a separate recognition proceeding in China — adding 12-18 months and significant legal costs — before it can be enforced.
Language: Chinese as controlling
The contract must be bilingual (Chinese and English) with a clause stating that the Chinese version controls in case of any conflict. This eliminates the translation problem in litigation. The judge can read the Chinese version directly without needing court-certified translation of every English term.
Quality specifications and acceptance criteria
Define product specifications with objective, measurable criteria. Specify inspection rights (third-party inspection before shipment at buyer's cost). Define acceptance/rejection procedures and timeframes. Without these, the court has no standard against which to measure the supplier's performance.
Penalty/liquidated damages clause
Specify liquidated damages for late delivery, non-conforming goods, and non-delivery. Under PRC law, liquidated damages must be "reasonable" — typically 0.05%-0.1% of contract value per day of delay, capped at the contract value. Excessive penalties can be reduced by the court, but having a specified penalty clause is vastly better than having none.
IP and confidentiality
Include IP assignment (the buyer owns all IP created under the contract), confidentiality/non-disclosure, and non-circumvention provisions. For OEM/ODM manufacturing, these are essential — without them, Chinese law defaults IP ownership to the manufacturer. Read our OEM contract clauses guide for the full list.
Enforceability Comparison at a Glance
| What You Can Enforce | English PO Only | English PI Only | Bilingual Contract |
|---|---|---|---|
| Return of deposit for non-delivery | Possible, but slow and expensive | Possible, but slow | Straightforward with penalty clause |
| Claim for defective goods | Very difficult — no quality specs | Very difficult — no quality specs | Enforceable with documented quality specs |
| Liquidated damages for delay | Not available — no penalty clause | Not available — no penalty clause | Enforceable per contract terms |
| IP infringement claim | Not available — no IP terms | Not available — no IP terms | Enforceable with IP assignment clauses |
| Asset preservation order | Possible but harder without clear contract | Possible but harder without clear contract | Straightforward — court has clear basis |
| Legal costs recovery | Not specified — unlikely | Not specified — unlikely | Specified if contract includes prevailing party clause |
Real-World Scenario: PO-Only Dispute
A client came to us after a $35,000 order of promotional products went wrong. The documentation: an English-language PO with product names, quantities, unit prices, and "Delivery: 45 days FOB Shenzhen." No quality specifications, no inspection clause, no penalty clause, no governing law.
The goods arrived: wrong colors, printing misaligned, packaging damaged. The supplier argued the goods "matched the PO" — and technically, the supplier was right. The PO said "5000 units, Model A-200, $7/unit" and the supplier delivered 5000 units of something labeled A-200.
The client had no legal basis to reject the goods because the PO contained no quality specifications that a Chinese court could test the goods against. The client's email exchanges discussing color codes and print alignment — while persuasive to a Western buyer — were not incorporated into the PO by reference and were not in Chinese. The case settled for a partial refund after legal demand letters, but the client lost approximately $18,000 because the PO alone provided no enforceable quality standard.
A bilingual contract with a 2-page quality specification appendix would have made this an open-and-shut case — the goods either met the spec or they did not. Instead, the client's entire legal position depended on interpreting WeChat messages and emails as contractual terms, which is a difficult argument to win in a Chinese court.
When You Need a Formal Contract (Decision Framework)
- Orders under $3,000 with existing, verified suppliers: A PI with embedded contract language may be sufficient — but the PI must include quality specs, payment milestones, and a jurisdiction clause, even if brief.
- Orders $3,000-$20,000: A bilingual short-form contract covering the six clauses above is recommended. Cost of drafting: approximately one hour of legal work.
- Orders $20,000+ or first-time supplier: A comprehensive bilingual contract is essential. The cost of a properly drafted contract is 1-5% of the transaction value. The expected loss from an unenforceable PO or PI dispute on a $20,000+ order is far higher.
- OEM/ODM with IP exposure: A full bilingual OEM contract with IP assignment, NNN integration, mold ownership, and exit provisions is non-negotiable — regardless of order value.
Our Contract Review & Drafting service covers all of these scenarios with transparent pricing from $299 to $1,999.
Frequently Asked Questions
Yes. This is a cost-effective approach for smaller transactions. We draft contract language — quality standards, penalty clauses, governing law, and jurisdiction — and embed it into your existing PI template. The resulting PI functions as both a commercial invoice and a legally enforceable short-form contract. This is available through our Contract Review Tier 2 ($599). The supplier simply signs the enhanced PI, and it becomes binding. This approach is not appropriate for complex OEM/ODM transactions with IP exposure, where a full bilingual contract is necessary.
Under Chinese law, a contract is valid with either the company's official chop (公章) or the legal representative's signature. In practice, the company chop carries more weight in Chinese courts because it is uniquely registered with the Public Security Bureau and is difficult to forge. A contract signed only with a signature — particularly from someone who is not the legal representative — raises questions about whether the signatory had authority to bind the company. We recommend: chop + legal representative signature for all contracts above $10,000. Our service verifies the chop against the company's registered chop specimen where possible.
A supplier's template contract is drafted for the supplier's benefit. It will almost certainly: exclude liability for quality defects, limit damages to the purchase price, designate the supplier's local court (which may be friendly to local companies), and contain no IP protection clauses. Before signing any supplier-drafted contract, have it reviewed by a PRC-licensed lawyer who can identify what is missing and what provisions are unfavorable. This is our Contract Review Tier 1 ($299) — we review the supplier's contract, flag every problematic clause, and provide recommended revisions in both English and Chinese.
No. Standard contract templates from US, UK, or other Western jurisdictions are drafted for those legal systems. They reference statutes that Chinese courts do not apply (UCC, Sale of Goods Act, CISG provisions inapplicable to China), use legal concepts Chinese judges interpret differently, and typically specify foreign law and foreign courts — which Chinese courts will not enforce against a Chinese supplier. A template that protects you in New York or London may be worthless in Shenzhen. The contract must be drafted specifically for enforcement under PRC law in Chinese courts — which is exactly what our contract drafting service provides.
