Key Takeaways
- Machinery orders are higher-value ($50,000–$500,000+) and disputes are exponentially more expensive to resolve
- The warranty period must start from installation and acceptance — not from shipment. A warranty that expires during shipping is worthless
- CE marking fraud is common in machinery exports; always verify certificates directly with the issuing notified body
- Spare parts obligations, performance guarantees, and acceptance testing procedures must be explicitly written into the contract
- Machinery disputes require specialized legal representation — generic commercial litigation experience cannot address the technical and jurisdictional complexity
Why Machinery Contracts Are Different from Consumer Goods
A contract for 10,000 USB cables is fundamentally different from a contract for one CNC machining center. In the USB cable scenario, the remedy for defective goods is straightforward: return the shipment, get a refund or replacement, and move on. The damage is contained to the value of the order.
A machinery deal is different in three critical ways:
- Value concentration. A single machine can represent half a year of production budget. A defect that takes the machine offline stops the buyer's entire production line.
- Deferred performance. USB cables work or they do not — the defect is apparent upon inspection. A milling machine may pass a 30-minute factory test and fail after 200 hours of production use. The contract must cover performance over time, not just at delivery.
- Interdependent obligations. Machinery contracts involve installation, commissioning, training, and ongoing spare parts supply. The supplier's obligations do not end when the equipment leaves the factory — they continue for months or years.
These three factors make machinery sourcing from China a high-stakes exercise in contract drafting. The contract is not a formality — it is the only thing standing between you and a $200,000 piece of equipment that does not work.
The Unique Risks of Sourcing Machinery from China
| Risk | How It Manifests | Financial Impact |
|---|---|---|
| Installation failure | Supplier ships the machine but provides no installation support, or sends untrained technicians who cannot commission the equipment | Buyer pays for the machine, shipping, and customs — then must hire local technicians at significant additional cost |
| Warranty timing gap | Warranty period begins at shipment. By the time the machine clears customs, arrives, and is installed, 3–4 months of the 12-month warranty have expired | Effective warranty period reduced by 25–50%; defects discovered after the paper warranty expires are unrecoverable |
| Spare parts unavailability | The supplier ceases production of the model, changes component suppliers, or goes out of business — and no spare parts are available | Entire machine may become inoperable for lack of a single custom component; replacement cost equals a new machine |
| CE/regulatory fraud | Supplier provides CE certificate for a compliant unit but ships a non-compliant or differently configured machine | Machine seized by EU customs; buyer faces fines, recall costs, and inability to use the equipment in the EU market |
| Performance shortfall | Machine meets speed, accuracy, or output specifications only under ideal conditions, not in the buyer's actual production environment | Production capacity reduced; buyer cannot meet customer commitments; downtime costs accumulate daily |
The Acceptance Testing Clause: Your Single Most Important Protection
Acceptance testing is the process by which the buyer confirms the machinery meets the agreed specifications before releasing final payment. A well-drafted acceptance testing clause defines not just what is tested, but when, where, by whom, and under what conditions.
Factory Acceptance Test (FAT)
The FAT happens at the supplier's factory before shipment. The buyer or the buyer's representative witnesses the test. This is the opportunity to confirm that the machine performs to specifications before it leaves China.
Your contract should specify:
- Test parameters: exact performance specifications, not "standard operation." Include speed, accuracy, output rate, and tolerance levels.
- Test materials: the materials used during the test (if the supplier uses ideal materials for the test and you use different materials in production, the test is meaningless).
- Pass/fail criteria: objective, measurable standards. "Produces at least 200 units per hour at ±0.05 mm tolerance" rather than "operates normally."
- Buyer's right to attend: the buyer or a third-party inspector must be present, with costs of attendance specified.
- Remedy for FAT failure: if the machine fails FAT, the supplier must correct deficiencies within a specified timeframe, or the buyer may cancel with full refund.
Site Acceptance Test (SAT)
The SAT happens at the buyer's facility after installation and commissioning. This is the true test — the machine operating under real production conditions.
Critical contract elements for SAT:
- SAT must happen after installation. The contract should explicitly state that installation and commissioning are the supplier's responsibility and at the supplier's cost.
- SAT defines when final payment is due. Tie the final payment — typically 10–20% of the total — to successful SAT completion, not to shipment.
- SAT timeline: specify how long after installation the SAT will occur (e.g., within 14 days of commissioning) and how long the supplier has to correct deficiencies before triggering penalties.
The Warranty Clause: When It Starts and What It Covers
The single most common mistake in machinery contracts from Chinese suppliers is the warranty start date. Supplier-drafted contracts almost always start the warranty from the date of shipment — meaning the warranty clock is running while the machine sits on a ship, waits in customs, and travels to your facility.
Standard Supplier Warranty vs What You Need
- Supplier contract: Warranty starts at shipment — even though the machine has not been unboxed
- Your contract: Warranty starts from the date of successful SAT or, if no SAT, from the date of installation and commissioning
- Supplier contract: Warranty covers "manufacturing defects" without defining the term
- Your contract: Warranty covers any failure to meet the performance specifications in the contract, including degradation over time within the warranty period
- Supplier contract: Warranty remedy is "repair at supplier's factory" — buyer pays shipping
- Your contract: Warranty remedy is repair or replacement at the buyer's site, at the supplier's cost, including parts, labor, and technician travel
A properly drafted warranty clause also includes a response time obligation: if the machine fails, the supplier must dispatch a technician within a specified number of days (e.g., 5 business days) and resolve the issue within a specified timeframe. Without this, you may have a warranty in theory but no practical way to enforce it when production is stopped.
Spare Parts and Long-Term Support
Industrial machinery has an operational life of 10–20 years. The supplier's obligation to support the machine should not end after the warranty period. A spare parts clause protects against the most common long-term risk: a machine becoming inoperable because a single custom component is no longer available.
Spare Parts Obligation Checklist
- Supplier guarantees availability of all critical spare parts for 10 years from the date of shipment
- Supplier provides a complete bill of materials with part numbers, specifications, and original manufacturer for every component
- Supplier supplies a recommended spare parts list with the initial shipment (critical wear items: belts, bearings, seals, sensors)
- Supplier commits to providing alternate source information if a component manufacturer discontinues a part
- Supplier agrees to release all technical documentation (schematics, software, calibration procedures) upon payment of 90% of the contract price — so the buyer can self-service if the supplier ceases operations
CE Marking and Regulatory Compliance
For machinery imported into the European Union, CE marking is mandatory for many equipment categories under the Machinery Directive 2006/42/EC. Chinese suppliers regularly provide CE certificates — but the certificate may not reflect the actual machine being shipped.
Common CE fraud patterns:
- The CE certificate was issued for a machine with different electrical components, safety guards, or control systems than the unit being shipped
- The CE certificate applies to the "model range" but the specific configuration being purchased was never tested
- The notified body number on the certificate is fake or belongs to a lab that has been suspended
- The Declaration of Conformity is signed by someone who does not have authority to bind the manufacturer
Your contract must address CE compliance with precision:
CE Compliance Contract Requirements
- Supplier warrants that the machinery as shipped conforms to the technical file submitted to the notified body
- Supplier provides a valid Declaration of Conformity and CE certificate for the exact model and configuration
- Buyer has the right to verify the CE certificate directly with the notified body
- Supplier indemnifies the buyer for all costs, fines, and losses arising from non-compliant CE marking
- If the machinery is detained by customs or regulatory authorities, the supplier is in material breach and the buyer is entitled to full refund plus damages
Performance Guarantees and Liquidated Damages
Consumer goods contracts rarely need performance guarantees beyond basic specifications. Machinery contracts do — because the cost of underperforming equipment extends far beyond the purchase price. If a production line that should produce 10,000 units per month produces 7,000, the buyer loses the profit on 3,000 units every month, indefinitely.
Performance guarantee clauses should include:
- Rated output: The machine will produce X units per hour/day at Y quality level under specified operating conditions.
- Uptime guarantee: The machine will achieve Z% uptime (e.g., 95%) over the warranty period, excluding scheduled maintenance.
- Liquidated damages: If the machine fails to meet performance specifications, the supplier pays a defined amount per day/week of non-conformance, up to a cap. Under PRC law, liquidated damages must be a reasonable pre-estimate of loss — a court may reduce excessive amounts.
- Ultimate remedy: If performance shortfall exceeds a defined threshold (e.g., 30% below specification for more than 60 days), the buyer may reject the machinery and demand full refund.

Why Machinery Disputes Need Specialized Representation
Machinery disputes are among the most complex international commercial cases. They require expertise in three areas that rarely overlap:
- PRC contract law and arbitration procedure — the legal framework for enforcement
- Industrial engineering and manufacturing processes — to understand whether the machine actually failed to meet specifications
- Cross-border logistics and trade finance — to trace payment flows, shipping records, and customs documentation
A general commercial litigator in the buyer's home country cannot effectively handle a PRC machinery dispute. The contract must choose PRC law and CIETAC arbitration — and you need a PRC-licensed attorney who has handled equipment disputes before. Our due diligence service identifies the supplier's litigation history and financial position before you commit to legal action.
Frequently Asked Questions
The standard structure is 30/60/10: 30% deposit with the order, 60% upon successful Factory Acceptance Test (FAT), and 10% upon successful Site Acceptance Test (SAT) after installation. For very high-value machinery ($200,000+), a 20/30/40/10 split may be appropriate, with payments tied to raw material procurement, mid-production inspection, FAT, and SAT. Never pay 100% upfront, and always retain at least 10% until SAT completion. For more on payment structures, see our guide to supplier payment terms.
Yes — if your contract provides for it. The contract should specify that failure to pass FAT or SAT within a defined number of attempts (typically 2–3) entitles the buyer to cancel the order and receive a full refund, including the deposit. Under PRC Contract Law, if the goods do not conform to the contract and the non-conformity constitutes a fundamental breach, the buyer may terminate the contract and claim damages. The key is documenting the failure clearly — with test data, photographs, and a written FAT/SAT report signed by both parties.
This is a common problem — the supplier promises experienced engineers and sends junior technicians who cannot commission the equipment. Your contract should specify: the minimum qualifications and experience of the installation team, the number of technicians provided, the duration of on-site support, and the remedy if the supplier fails to provide qualified personnel (such as the right to hire local technicians at the supplier's expense). Include a requirement that the lead technician's CV be provided with the contract.
Do not dismantle or modify the machine. Document all performance shortfalls with data logs, production records, and photos. Hire an independent equipment appraiser or engineer to produce an expert report. Send a formal notice of breach to the supplier in both English and Chinese, specifying the deficiencies and the remedy demanded. Then consult a PRC-licensed attorney. The supplier's bank accounts in China can be frozen through asset preservation while the case proceeds. Our litigation team has handled machinery disputes ranging from $50,000 to over $1 million in equipment value.
