How to Sue a Chinese Supplier in Mainland China for Non-Delivery or Defective Goods

You paid a deposit to a Chinese supplier. The delivery date passed. The supplier kept promising that the goods were “almost ready,” but nothing arrived.

Or perhaps the goods arrived, but they did not match the agreed sample, specifications, inspection standard, or technical requirements. You asked for a refund or replacement. The supplier delayed, blamed a subcontractor, or stopped responding.

At that point, many foreign businesses ask:

Can we sue the supplier in China, and what should we do first?

The short answer is: potentially yes—but the best first step is not always filing a lawsuit immediately.

A practical China-side strategy usually begins by identifying the correct legal entity, preserving the evidence, checking the contract, assessing available assets, and choosing between negotiation, platform remedies, arbitration, litigation, or other procedures.

This article provides a general framework for foreign businesses. It is not legal advice, and the correct route depends on the contract, the facts, the parties, the evidence, and the applicable procedure.

1. First identify what actually went wrong

“Supplier dispute” can describe several different legal and commercial problems.

The supplier never delivered

The buyer paid a deposit or the full price, but the supplier did not ship the goods by the agreed deadline.

The key questions include:

• Was there a clear delivery date?
• Did the supplier admit that delivery was late or impossible?
• Was the buyer required to provide specifications, approvals, or documents before production?
• Did the supplier actually manufacture the goods?
• Was a partial shipment made?
• Was the payment made to the contracting company or to another entity?

The supplier delivered late or only partially

A late delivery may be a breach, but the legal consequences depend on the contract and the commercial purpose of the transaction.

Missing a seasonal sales window may cause a different type of loss from a delivery delay that does not affect the buyer’s business. The contract may also contain a grace period, liquidated damages clause, or procedure for extending the delivery schedule.

The goods are defective or do not conform

A quality dispute may involve different materials, dimensions, technical specifications, safety or performance failures, missing components, packaging defects, or goods that cannot be resold or used for their intended purpose.

The important question is not simply whether the buyer is unhappy with the goods. It is whether the buyer can prove what was promised, what was delivered, how the goods differed, and what loss resulted.

The supplier refuses a refund or replacement

A supplier may acknowledge the problem but continue postponing repayment. It may promise replacement goods, offer a partial refund, or ask the buyer to pay additional amounts before releasing the shipment.

Those communications can become important evidence. They may show acknowledgment of the transaction, the delivery problem, the quality issue, or the supplier’s continuing obligation.

2. Preserve evidence before the dispute becomes harder to prove

A strong claim can become weak if the evidence is incomplete, disconnected, or preserved too late.

Evidence of non-delivery

A foreign buyer should collect and organize:

• The signed contract;
• Purchase orders and order confirmations;
• Invoices and payment records;
• The agreed delivery date;
• Shipping instructions;
• Bills of lading, booking records, and tracking information;
• Customs and warehouse documents;
• Messages in which the supplier discusses production or shipment;
• Any admission that the supplier cannot deliver;
• Refund requests and the supplier’s responses.

The purpose is to build a clear timeline:

Contract → payment → promised delivery → missed deadline → supplier explanation → demand for performance or refund.

Evidence of defective or non-conforming goods

For a quality dispute, the evidence may include:

• The approved sample;
• Product specifications and drawings;
• Technical standards;
• Inspection and quality-control records;
• SGS or other inspection reports;
• Photographs and videos;
• Product samples and packaging;
• Test results;
• Records of customer complaints or rejected goods;
• Repair, replacement, disposal, or return costs;
• Communications notifying the supplier of the defect.

Do not return, destroy, repair, or dispose of disputed goods without considering how that action may affect the evidence. If goods must be moved or altered, document their condition first and obtain written confirmation where possible.

Chinese civil evidence rules recognize forms of electronic data such as websites, email, instant messaging, electronic transaction records, audio, video, and digital files. The authenticity, integrity, source, and relevance of the material still need to be assessed. Foreign public documents may also require notarization, authentication, an Apostille, or another applicable procedure depending on the document and proceeding. See the Supreme People’s Court rules on civil litigation evidence.

The correct question is not “Do I need to notarize everything?” It is:

Which evidence must be proved, what is its source, and what form will the receiving court or tribunal accept?

What if the goods fail customs testing or cannot be cleared?

A failed test or a customs hold is a reason to investigate the supplier claim, not automatic proof that the supplier must refund every loss. Separate a product defect from missing import documents, a labelling issue, or a disagreement about the applicable standard. Requirements for challenging an overseas customs decision need advice from qualified counsel in that jurisdiction.

Start with three groups of records:

• The agreement: the order, specifications, destination requirements communicated to the supplier, and any inspection or certification promises.
• Payment and shipment: payment receipts, invoices, packing lists and batch or container identifiers.
• The failure record: the complete customs notice and test report, sampling records, tested substances or parameters, applicable limits, and any deadline for responding.

Keep the original report and identify where the goods and retained samples are held. Record supplier notifications and itemize storage, retesting, return or disposal costs. Plan evidence preservation alongside any mandatory local deadlines; do not assume the whole shipment failed because a sample failed.

Goods not delivered, defective, or held after testing? Tell us what was ordered, what failed and any deadline. Request a supplier-dispute review. A short summary is enough to start; we will explain which documents are needed next. See our supplier-dispute service.

3. Identify the correct Chinese defendant

Many foreign buyers know a supplier by its English brand name, website, platform profile, factory sign, or sales representative. None of those necessarily identifies the legal entity that should be sued.

The contract may have been signed by a trading company, manufacturer, export company, related company, Hong Kong company, individual representative, or a company using a different Chinese name from its English brand.

Before filing, compare:

• The exact Chinese company name;
• The unified social credit code;
• The registered address;
• The legal representative;
• The company chop;
• The bank account receiving payment;
• The name on the invoice;
• The name on shipping and customs records;
• The factory or warehouse address;
• The identity of the person who negotiated and signed the contract.

A factory may have produced the goods without being the contractual seller. A trading company may have signed the contract while the manufacturing company controlled production. That relationship may be commercially important, but it does not automatically make every related entity liable.

The parties, contractual role, authority, payment records, communications, and legal basis for liability must be reviewed separately.

For more detail, see our Identify the Correct Chinese Defendant and Asset Investigation & Tracing in China services.

4. Check the contract before choosing the legal route

Review at least the following clauses:

• Governing law;
• Court jurisdiction;
• Arbitration institution and seat;
• Delivery deadline and location;
• Incoterms or shipping terms;
• Inspection standard and inspection period;
• Quality guarantee;
• Refund and replacement obligations;
• Liquidated damages;
• Limitation of liability;
• Language and prevailing-language clauses;
• Notice and demand requirements.

A valid arbitration agreement may prevent the buyer from simply filing the merits of the dispute in court. Conversely, a defective or incomplete arbitration clause may create a jurisdictional dispute before the merits are considered.

If the contract does not contain a clear dispute-resolution clause, the available court route may depend on the defendant’s domicile, the place of performance, the location of relevant property, or another legally recognized connection.

Under the PRC Civil Procedure Law, certain foreign-related disputes may be heard by a Chinese court when the contract, performance, property, or another appropriate connection is located in China. Parties may also agree in writing to choose a Chinese court, subject to applicable legal restrictions. See the official text of the PRC Civil Procedure Law.

5. Compare the available response routes

These routes are not automatically interchangeable. A platform complaint may have a contractual deadline. A payment dispute may require specific records. A criminal report is not a substitute for a commercial breach claim, and a supplier’s failure to perform is not automatically fraud.

Before taking action, preserve the evidence and understand whether one step could affect another. Accepting replacement goods, signing a release, or agreeing to a refund schedule may change the scope of a later claim.

6. What can a buyer claim?

Depending on the contract and facts, possible remedies may include:

• Delivery of the contracted goods;
• Completion of a partial shipment;
• Repair or replacement;
• Return of defective goods;
• Termination or rescission where legally available;
• Return of a deposit or prepayment;
• Reduction of the purchase price;
• Contractual damages or liquidated damages;
• Reasonable inspection, storage, return, or replacement costs;
• Other losses that can be proved and are legally recoverable.

The PRC Civil Code addresses the contents of sales contracts, including goods, quantity, quality, price, delivery arrangements, inspection standards, payment terms, language, and the legal effect of different language versions. It also provides rules concerning non-conforming goods and contractual remedies. See the official Supreme People’s Court publication of the PRC Civil Code.

The buyer still needs to prove the legal and factual basis for each item. Lost resale profits, customer penalties, reputational damage, and other commercial losses are not automatically recoverable merely because the supplier breached the contract.

7. Where can the case be filed?

Potential considerations include:

• The defendant’s registered domicile;
• The place where the contract was performed;
• The place where the goods were to be delivered;
• The location of relevant property;
• A written court-jurisdiction clause;
• An arbitration institution specified in the contract;
• Whether the dispute concerns goods, services, intellectual property, or another subject;
• Whether a foreign court or tribunal has already accepted a related case.

The supplier’s factory location may be relevant, but it is not automatically the only competent court.

A favorable decision is less useful if the winning party has no practical way to recognize, preserve, or enforce it against reachable property.

8. How international sales law may affect the dispute

The United Nations Convention on Contracts for the International Sale of Goods, commonly known as the CISG, may apply to an international sale of goods when its conditions are satisfied and the parties have not validly excluded it.

The CISG can affect the seller’s delivery obligations, conformity of goods, inspection and notice duties, termination, price reduction, damages, and the effect of contract terms and trade practices.

Whether the CISG applies depends on the parties’ places of business, the transaction, the contract, exclusions, and applicable declarations. China and the United States are both listed as CISG parties, but the existence of two CISG countries does not answer every legal question. See the UNCITRAL CISG status table.

9. Public case: substandard masks detained by customs

MaRa Medical-Technical-Aid GmbH v. Ningbo Laida Automotive Technology Co., Ltd. — Zhejiang High People's Court, (2022) Zhe Min Zhong No. 1205, February 16, 2023; CLOUT 2204.

A German buyer paid for masks, some of which were detained by customs and could not be delivered. The seller blamed the buyer's CE-mark instructions. The appellate court attributed the non-delivery to substandard masks and export-declaration failures, and upheld repayment and interest for the undelivered portion.

The practical point is to identify why clearance failed and which obligations were breached. This was a China export-detention case; it does not decide liability whenever goods fail testing at a foreign destination.

These decisions are public examples, not matters presented as our firm's results. Each turns on its own evidence and legal framework.

10. Public case: non-delivery and quality problems

According to a published China International Commercial Court case summary, a dispute involving a foreign buyer and a Chinese supplier concerned multiple shipments, advance payment, delayed delivery, quality complaints, undelivered shipments, lawyer’s letters, and a later request for termination and repayment.

The practical lesson is that one supplier dispute may involve several connected issues:

1. Failure to meet the agreed delivery schedule; 2. Quality problems in goods that were delivered; 3. Failure to deliver remaining goods; 4. Communications acknowledging performance problems; 5. A documented request for repayment.

A buyer should therefore preserve the entire transaction record rather than collecting only photographs of defective goods.

See CICC CLOUT Case 2141, Beijing Fourth Intermediate People’s Court.

11. Public case: a quality report must match the disputed order

In another published international sale-of-goods case, a Chinese seller claimed payment from a foreign buyer. The buyer argued that some goods were defective and relied on an analysis report and related documents.

The court examined whether the report and supporting materials actually related to the specific order and goods in dispute. The published summary explains that the buyer’s evidence was connected to an earlier shipment rather than the order at issue. The buyer was therefore not entitled to deduct the disputed amount on that basis.

The lesson is important:

A quality report is not automatically proof of a quality claim.

The report should be connected to the correct order, shipment, batch, contractual standard, inspection date, inspection method, and alleged loss.

See CICC CLOUT Case 1700, Shanghai Pudong New District People’s Court.

12. Public case: cross-border quality appraisal

In a published case involving photovoltaic components, the dispute concerned whether products located outside mainland China met the agreed performance and quality requirements.

The court coordinated a process involving on-site testing outside mainland China, laboratory analysis in China, technical assessment of different possible causes, analysis of the seller’s share of responsibility, and calculation of economic loss.

This demonstrates that a quality dispute may require analysis of the sample scope, testing location, testing standard, post-delivery changes, installation, storage, transport, use, the condition of the goods at delivery, and the calculation of loss.

See the CICC summary of the cross-border quality appraisal case.

13. Practical pre-filing checklist

Prepare:

• The exact Chinese legal name of the supplier;
• The English and Chinese versions of the contract;
• Purchase orders and invoices;
• Payment records;
• The agreed delivery deadline;
• Product samples and specifications;
• Inspection and QC records;
• Photos and videos;
• Retained samples, if available;
• Emails, WeChat messages, and platform communications;
• Shipping, customs, warehouse, and tracking documents;
• The arbitration or court-jurisdiction clause;
• Evidence of refund requests;
• Records of replacement or repair costs;
• Evidence of commercial losses;
• Information about related companies or assets;
• Any urgency concerning asset transfer or company closure.

Do not send unnecessary passwords, private banking credentials, or unrelated personal information through an initial website form.

The first review should answer:

1. Who is the correct defendant? 2. What exactly was promised? 3. What exactly happened? 4. What evidence proves the difference? 5. Which dispute-resolution route applies? 6. Is there a realistic recovery target? 7. Is urgent preservation worth assessing?
