What to Do When a Chinese Supplier Fails an Inspection
An inspection failure is stressful, but it is not necessarily a disaster. How you respond in the hours and days after a failed inspection determines whether the situation is resolved well or badly.
Discovering that goods have failed a quality inspection is one of the more stressful moments in China sourcing. The shipment date is approaching, the customer is waiting, and the factory is telling you the problems are minor and easily fixed.
How you respond in the hours and days after a failed inspection will determine whether the situation is resolved well or badly. Here is a practical guide to managing it.
Step 1: Don't Panic
A failed inspection is not automatically a disaster. Many inspection failures involve problems that can be corrected — sorting, reworking, or replacing a proportion of the goods. The key is to establish exactly what has failed before deciding how to respond.
Reacting emotionally or making hasty decisions under pressure tends to produce worse outcomes than taking a measured approach.
Step 2: Establish Exactly What Failed
The first priority is to understand the nature and extent of the problem.
- What specific defects were found?
- How many items are affected?
- Are the defects distributed evenly across the production run, or concentrated in a particular batch or production period?
- Are the defects critical (affecting function or safety), major (affecting appearance or usability), or minor?
A good inspection report should give you this information clearly, with photographs and a description of each defect type. If the report is vague, ask for more detail before proceeding.
Step 3: Refer Back to the Agreed Specification
Before deciding whether goods are acceptable or not, refer back to the agreed specification and approved samples.
Sometimes what appears to be a defect is actually within the agreed tolerance. Sometimes what the factory describes as acceptable is clearly outside the specification. Having agreed standards in place — as discussed in our quality control guide — makes this assessment objective rather than a matter of opinion.
Step 4: Determine How Widespread the Problem Is
If inspection was conducted on a sample basis, the defect rate in the sample gives you a statistical indication of the defect rate in the full shipment — but it is an estimate, not a precise count.
For serious defects, it may be worth conducting 100% inspection of the affected items to establish the true extent of the problem. This takes time but gives you accurate information on which to base decisions.
Step 5: Identify the Root Cause
Understanding why the defects occurred is important for two reasons: it helps determine the appropriate corrective action, and it helps prevent the same problem recurring.
Common root causes include:
Material problems — wrong material, substandard material, material from an unapproved supplier. If the material is wrong, reworking the finished product may not be possible; replacement may be required.
Dimensional problems — incorrect tooling, worn tooling, incorrect machine settings, measurement errors. Dimensional problems in machined or fabricated components may require rework or replacement depending on the nature of the error.
Workmanship — poor assembly, inadequate surface preparation, inconsistent finishing. Workmanship problems are often correctable by rework, but the quality of rework needs to be verified.
Assembly errors — missing components, incorrect components, incorrect assembly sequence. Assembly errors are often correctable but require careful sorting and reinspection.
Surface finishing problems — poor paint adhesion, colour variation, surface contamination. Some finishing problems can be corrected by stripping and refinishing; others require replacement.
Packaging problems — incorrect packaging, inadequate protection, incorrect labelling. Packaging problems are usually correctable.
Step 6: Decide on the Appropriate Response
Once you understand the nature, extent, and cause of the defects, you can decide on the appropriate response.
Sorting — separating acceptable from defective items. Appropriate when defects affect a proportion of the shipment and acceptable items can be clearly identified.
Reworking — correcting defects that can be corrected. Appropriate when the defect is correctable and the rework will not compromise the product. Reworked items must be reinspected.
Replacing components — replacing defective components within an assembly. Appropriate when the defect is in a specific component that can be replaced without affecting the rest of the product.
Remanufacturing — producing replacement items. Appropriate when defects cannot be corrected and the affected items must be scrapped. This takes time and may affect your delivery schedule.
Accepting with concession — accepting goods with minor defects where the commercial impact is acceptable. This should be a conscious decision, not a default response to pressure.
Rejecting the shipment — refusing to accept the goods. Appropriate when defects are serious, widespread, and cannot be corrected within an acceptable timeframe.
Step 7: Corrective Action
Whatever response is chosen, agree the corrective action in writing with the factory. This should cover:
- What action will be taken
- Who is responsible
- The timeline
- How the corrected goods will be verified
Step 8: Reinspection
After corrective action, reinspection is essential. Do not accept the factory's assurance that defects have been corrected without independent verification.
The reinspection should focus on the specific defects identified in the original inspection, and should verify that the corrective action has been effective.
Why Shipping Goods With Unresolved Problems Is Risky
There is sometimes pressure — from the factory, from commercial deadlines, or from customers — to ship goods despite unresolved quality problems. This is rarely a good decision.
Once goods are shipped, your options narrow significantly. If the goods arrive in the UK with quality problems, you face the cost of returning them to China, negotiating a replacement shipment, or accepting substandard products and managing the consequences with your customer. None of these is straightforward or cheap.
The cost of resolving a quality problem in China — before shipment — is almost always lower than the cost of resolving it after the goods have arrived in the UK.
The Value of Having Someone in China
One of the most significant advantages of having people physically located in China is the ability to respond quickly when problems arise.
When a factory reports that defects have been corrected, someone can go and verify that they have. When a dispute arises about whether goods meet the specification, someone can examine the goods directly rather than relying on photographs and the factory's assurances.
For UK businesses managing suppliers remotely, this physical presence is difficult to replicate. Working with a China sourcing service that has people on the ground means problems can be investigated and resolved directly, rather than managed entirely by email from the UK.
