Defective Goods from a Chinese Supplier: What Can an Overseas Buyer Do?

September 23, 2026 · Jay Zhifeng Chen

An overseas buyer receives goods from a Chinese supplier and discovers that they do not meet expectations. The materials may differ from the approved sample, dimensions may be wrong, components may fail testing or part of the shipment may be unusable.

The supplier may dispute the defect, rely on an inspection report or argue that the goods were damaged during transport or storage.

A useful claim should connect the agreed quality requirements, the condition of the delivered goods, timely notification and the remedy sought.

Photographs may show a problem, but they do not always establish who is responsible or what compensation is due.

Short Answer

If goods from a Chinese supplier appear defective or non-conforming, an overseas buyer should usually:

1. identify the contractual quality standard and approved specifications;
2. inspect promptly and record when the problem was discovered;
3. notify the supplier within the applicable contractual and legal periods;
4. preserve representative samples, packaging and original records;
5. distinguish manufacturing defects from transport, storage or handling damage;
6. quantify the affected goods and resulting loss; and
7. assess whether repair, replacement, a price reduction, return or another remedy is appropriate.

A full refund is not the automatic remedy for every defect. The seriousness of the problem, contract, applicable law and available evidence matter.

1. Identify the Standard the Supplier Was Required to Meet

Begin with the documents defining the goods.

Relevant material may include:

• the signed contract and purchase order;
• technical drawings and specifications;
• approved samples;
• material or component requirements;
• tolerances and performance criteria;
• packaging and labelling requirements;
• agreed testing methods; and
• written descriptions supplied during negotiations.

Distinguish between a requirement that formed part of the agreement and an expectation that was never communicated or accepted.

If the parties changed a material, component or tolerance during production, preserve the approval history. The supplier may rely on that change when responding to the complaint.

For transactions governed by Chinese domestic sales law, Civil Code Articles 615–617 address agreed quality requirements and liability for non-conforming goods. See the PRC Civil Code.

2. Inspect and Notify Promptly

Review the contract for inspection, acceptance, warranty and complaint provisions as soon as a problem is identified.

Do not assume that a warranty period permits the buyer to postpone inspection or notification.

Where Chinese domestic sales law applies, Articles 620–623 address inspection and notice, including the consequences of failing to notify within applicable periods, treatment of an unreasonably short inspection period and the evidential effect of certain signed delivery documents. Their application depends on the facts and relevant exceptions. See the PRC Civil Code.

For international sales, the CISG may impose a separate examination and notice framework. The applicable regime should be identified before relying on a particular deadline. See UNCITRAL’s CISG materials.

A notice of defects and the time limit for commencing legal proceedings are different issues. Address both.

3. Make the Complaint Specific

A message stating “the quality is bad” may leave important questions unanswered.

A useful initial notice should identify:

• the order and shipment;
• the product, batch or serial numbers;
• the affected quantity;
• the observed problem;
• the specification or agreed requirement involved;
• when the problem was discovered; and
• the supporting photographs, test results or other records available.

If the full extent is still being investigated, explain that clearly and provide further information as it becomes available.

A timely, specific notice may be important even before the final loss calculation is complete. However, a general reservation of rights should not be assumed to replace the notice required by the contract or applicable law.

Keep evidence of when and how the complaint reached the supplier.

4. Preserve Samples and Original Evidence

Before repairing, returning, disposing of or extensively using the goods, consider what evidence will remain available.

Preserve, where practicable:

• representative defective units;
• unaffected comparison units;
• approved reference samples;
• original packaging and labels;
• batch and serial-number records;
• inspection and test reports;
• photographs and videos in their original form; and
• records of receipt, storage and handling.

Maintain a clear record of who selected, stored, tested or moved samples.

Where destructive testing is necessary, consider documenting the procedure and retaining other representative samples. An independent inspection or laboratory report may be useful, but its value depends on the sampling method, test standard and connection to the disputed shipment.

If urgent action is necessary to protect people or prevent further loss, document the condition and reasons for that action as fully as practicable.

5. Identify the Likely Cause

Not every problem discovered after delivery arose during manufacture.

Potential causes include:

• incorrect materials or components;
• manufacturing or assembly defects;
• inadequate packaging;
• transit damage;
• storage conditions;
• installation errors; or
• use outside the agreed operating requirements.

The buyer does not necessarily need to resolve every technical question before notifying the supplier. However, causation will often matter to the eventual claim.

For example, corrosion may require examination of materials, protective treatment, packaging, transit conditions and storage. A photograph of corrosion alone may not identify the responsible party.

If carrier or insurance claims may also be relevant, check their notice and evidence requirements promptly rather than relying only on discussions with the supplier.

6. Choose a Remedy That Fits the Problem

The appropriate remedy depends on the contract, applicable law, seriousness of the non-conformity and practical circumstances.

Possible outcomes include:

Repair or Rework

This may be workable where the defect can be corrected promptly and the resulting goods will meet the agreed requirements.

Agree who performs the work, the standard for completion, inspection arrangements and responsibility for costs.

Replacement

Replacement may be suitable where repair is impractical but the supplier can provide conforming goods within a commercially useful period.

Address return arrangements, shipping costs and verification of the replacement goods.

Price Reduction

A price reduction may be commercially sensible where the buyer can use or sell the goods despite a limited deviation. The settlement should identify the affected goods and what claims are being resolved.

Return or Termination

More serious non-conformity may justify considering return or termination, but the buyer should establish the necessary legal basis before acting.

Damages

An additional compensation claim may be available where the relevant requirements are met. Avoid counting the same loss twice when combining remedies.

If Chinese domestic law applies, Articles 582 and 617 address remedies for non-conforming performance. Article 610 concerns quality non-conformity that prevents achievement of the contractual purpose. These provisions do not make a full refund available for every minor defect.

7. Do Not Return or Dispose of Goods Without a Plan

Sending goods back to China may create transport, customs, storage and evidential problems.

Before arranging a return, clarify:

• whether the supplier agrees to receive the goods;
• the authorised recipient and address;
• who pays freight and related charges;
• the customs arrangements;
• what happens if delivery is refused; and
• when and on what conditions repayment or replacement will occur.

Unilateral disposal can also complicate proof and recovery. Where goods must be destroyed or otherwise dealt with, preserve appropriate evidence and consider whether the supplier should be offered a reasonable opportunity to inspect.

The appropriate approach depends on urgency, safety requirements, the nature of the goods and the applicable legal position.

8. Quantify the Claim Carefully

Prepare a schedule separating:

• the purchase price of affected goods;
• inspection and testing costs;
• repair or rework expenses;
• additional transport and storage;
• replacement procurement; and
• other claimed losses.

For each item, retain documents showing the amount, payment and connection to the breach.

Downstream customer refunds, lost sales and business interruption may be disputed. They require more than a general estimate.

The buyer should also take reasonable steps to prevent avoidable additional loss. Commercial decisions about sorting, repair, resale or replacement should be documented, including why the chosen option was reasonable.

9. Address the Supplier’s Response

The supplier may rely on a passed pre-shipment inspection, signed receipt, alleged misuse or a limitation clause.

Review what the inspection actually covered. A report based on a particular sample or test may not determine every issue involving the shipment. Conversely, evidence of inspection and acceptance should not be dismissed without analysis.

If settlement is possible, record the affected quantities, agreed remedy, deadlines, costs and scope of any release.

A promise of credit against future orders is only useful if the buyer is willing and able to continue purchasing from the supplier.

10. When to Consider Formal Action

A lawyer’s demand may be appropriate once the key evidence and requested remedy are sufficiently clear.

For a technical dispute, further inspection or expert input may be needed before the claim can be presented reliably.

Before litigation or arbitration, assess the dispute-resolution clause, correct supplier entity, notice history, evidence, recoverable loss, available assets and likely costs.

Frequently Asked Questions

Can I demand a full refund for defective goods?

Not automatically. The appropriate remedy depends on the seriousness of the defect, contract, applicable law and evidence. Repair, replacement or a price reduction may be more appropriate in some cases.

Does a passed pre-shipment inspection prevent a claim?

Not necessarily. Review the inspection’s scope, sampling method, agreed effect and whether the defect could reasonably have been identified. Acceptance and notice provisions still require attention.

Are photographs enough?

They may help, but often need support from specifications, samples, testing, quantity records and evidence linking the problem to the supplier’s performance.

Should I wait for a laboratory report before complaining?

Do not assume that waiting preserves your rights. A prompt, specific initial notice may be important while testing continues. Review the applicable notice requirements.

What if only part of the shipment is defective?

Identify the affected quantity and whether the problem is confined to particular units or indicates a wider batch issue. The remedy should reflect the evidence and contractual position.

Can I repair the goods locally and charge the supplier?

Possibly, but the legal basis, necessity, opportunity for the supplier to respond and reasonableness of the cost need consideration. Preserve evidence before repair.

Can I stop paying the remaining balance?

That requires review of the contract and applicable law. Withholding payment without a sufficient basis may expose the buyer to a counterclaim.
