A pre-shipment inspection catches problems before goods leave China — when fixing them is still possible and relatively cheap.
Once a shipment arrives at your destination, options narrow significantly. Defective goods are expensive to return, rework, or dispose of. Disputes with suppliers become harder once goods have cleared customs and payment has been released. A pre-shipment inspection — done while goods are still at the factory — gives you a chance to identify problems and act before that point.
This guide explains what a pre-shipment inspection is, when small importers should use one, how to arrange it, and what to do if the inspection fails.

What Is a Pre-Shipment Inspection?
A pre-shipment inspection (PSI) is a quality check performed at the factory, typically when production is 80–100% complete and goods are ready to pack or already packed.
An inspector — usually from an independent third-party company — visits the factory and checks a sample of the finished goods against your specifications, approved sample, and packaging requirements. They document findings in a written report with photos.
A PSI typically checks:
- Quantity and carton count
- Workmanship and finish quality
- Dimensions and weight against specifications
- Packaging and labeling
- Functionality for applicable products
- Compliance with any specific requirements you have provided
What a Pre-Shipment Inspection Does Not Guarantee
A PSI reduces risk, but it does not eliminate it. Understanding the limits is as important as understanding what it covers.
A PSI does not typically:
- Inspect every single unit — it samples from the batch, not every product
- Certify products as legally compliant or safe for sale in your market
- Guarantee future product performance in use
- Replace product safety testing or regulatory certification
- Confirm legal compliance for regulated products
- Protect you if the supplier swaps or alters goods after the inspection is completed
An inspector can only check against the standards you provide. If your specifications are vague, the inspection report will be limited.
When Should Small Importers Use a Pre-Shipment Inspection?
A PSI is most useful when it happens before you release the final balance and before the supplier ships the goods. At that point, you still have leverage — you can request rework, hold shipment, or withhold payment until issues are resolved.
Consider a PSI when:
- It is your first bulk order with a new supplier
- The order value is significant enough that a quality problem would affect your cash flow — as a rough guide, many importers find PSI worthwhile for orders above $2,000–$3,000, though this depends on your risk tolerance and product type
- The product is customized, branded, or private label
- The product is quality-sensitive, safety-related, or will be sold in a regulated market
- You are about to release the final payment balance before shipment
- Your sample passed but you want to confirm bulk production matches it
PSI is less critical when:
- You are ordering a repeat from a supplier you have worked with successfully before
- The order value is very small relative to inspection cost
- You have other quality controls in place
The core question is: what would a quality failure cost me, compared with the cost of the inspection?
Who Should Do the Inspection?
| Option | Best For | Pros | Risks |
|---|---|---|---|
| Third-party inspection company | First bulk orders, higher-value orders, quality-sensitive products | Independent, formal report, standardized process | Extra cost |
| Sourcing agent | Smaller orders, agent-managed 1688 orders | Convenient, already involved in the supply chain | May not be fully independent from the supplier |
| Factory visit by you | High-value or strategic supplier relationship | Direct control and observation | Travel cost, time, and logistics; usually not practical for beginners |
| Supplier self-inspection | Very small repeat orders with a trusted supplier | Free and easy | Least independent; limited value for new relationships |
A factory self-inspection can be useful as a preparation step, but it should not be treated as an independent inspection for a new supplier or high-risk order. A supplier-issued QC report is not a substitute for third-party verification.
For most small importers placing a first or second bulk order, a third-party inspection company provides the most reliable and documented result.
Examples of well-known third-party inspection companies include QIMA, SGS, Bureau Veritas, Intertek, and TÜV. Mentioning these companies is for category awareness only — not a recommendation or endorsement. Always compare service scope, pricing, location coverage, report format, and turnaround time before choosing a provider. For small importers, the best inspection company is often the one that can cover your product category, factory location, and timeline clearly.
How to Arrange a Pre-Shipment Inspection
Step 1: Contact the inspection company before production finishes
Book the inspection early. Most providers need a few days’ notice, and scheduling depends on inspector availability in the factory’s region. Do not wait until the supplier says goods are ready.
Step 2: Provide all relevant documents and standards
Send the inspection company:
- Purchase order or order confirmation
- Product specification sheet
- Approved sample photos from multiple angles
- Packaging and labeling requirements
- Defect examples if available
- Quantity, carton count, and carton dimensions
- Factory address, contact person, and contact number
- Any specific inspection focus points you want prioritized
The inspector will check against what you provide. The more complete your brief, the more useful the report.
Step 3: Coordinate with your supplier
Inform the supplier that an inspection will take place. The supplier needs to have goods ready and available at the factory on the inspection date.
Step 4: Receive and review the report
Most inspection companies deliver a report within 24 hours of the inspection. Review the defect photos carefully, not just the final result. A “pass” with several minor defects may still warrant a conversation with the supplier before shipment.
Rough cost reference: As a planning estimate, many standard pre-shipment inspections cost around $200–$400 per man-day, depending on location, product type, inspection scope, and provider. Specialized products, remote factory locations, or urgent schedules may cost more. For a $3,000–$10,000 first bulk order, this is often one of the cheapest forms of risk control available.
AQL in Plain English
Pre-shipment inspections typically use AQL — Acceptable Quality Limit — as the sampling framework. You do not need to become an AQL expert, but understanding the basics helps you read a report.
AQL is a sampling method, not 100% inspection. The inspector checks a defined number of units from the batch — not every single unit. The sample size depends on the total quantity and the AQL level specified.
Defects are classified into three categories:
Critical defect — A problem that makes the product unsafe, illegal to sell, or fundamentally unacceptable. Critical defects usually result in automatic failure.
Major defect — A problem that significantly affects function, appearance, customer experience, or saleability. Major defects are held to a stricter acceptance threshold.
Minor defect — A small issue that does not typically affect function but may still matter if it appears consistently across many units.
Pass or fail is determined by whether the number of defects found in the sample exceeds the threshold for each defect category.
The practical takeaway: a passed inspection means the sampled units met the standard at the time of inspection. It does not mean every unit is perfect, and it does not mean goods cannot change between inspection and delivery.
What a Pre-Shipment Inspection Report Usually Includes
- Date, factory location, and inspector details
- Product description and order reference
- Quantity checked and quantity found
- Carton and packaging check
- Workmanship and appearance assessment
- Dimension and weight measurements
- Functionality test results if applicable
- Defect list with photos, categorized by severity
- Overall result: Pass / Fail / Pending
What to Do If the Inspection Fails
A failed inspection is not the end — it is information you can act on while goods are still in China.
Minor issues or small defect counts:
Ask the supplier to sort, rework, or replace the affected units before shipment. Ask the supplier to confirm the corrective action plan in writing — including what will be fixed, how, and by when — before you approve shipment or release final payment. Arrange a re-inspection after rework if needed.
Significant or systemic defects:
Do not release payment or approve shipment until the issue is addressed. Contact the supplier with the inspection report and specific photos. Request a written corrective action plan and timeline.
Fundamental production problems:
If the goods do not match specifications in a major way — wrong material, wrong construction, wrong labeling — hold the shipment. This is when the inspection has done exactly what it was supposed to do.
Do not release the final payment balance until:
- You have reviewed the inspection report
- Any rework has been completed and confirmed in writing
- You are satisfied that goods meet the agreed standard
Payment timing is one of your strongest tools. Use it.
Common Mistakes
Scheduling the inspection after goods have already shipped
Once goods leave China, your options narrow significantly. Book the inspection before shipment is approved.
Paying the final balance before inspection
If you have released full payment, you have less leverage to request rework or withhold shipment. Structure payment to keep a portion until after inspection.
Not giving the inspector clear specifications
A vague brief produces a limited report. Send product specs, sample photos, and specific focus points before the inspection date.
Treating a passed PSI as product safety certification
A PSI checks workmanship, appearance, quantity, and packaging against your specifications. It does not certify that the product meets safety standards or regulatory requirements for your market.
Ignoring repeated minor defects
A single minor defect may not fail an inspection, but the same minor defect appearing across many units in the sample suggests a production consistency problem worth addressing.
Not planning time for rework or re-inspection
If the inspection fails, you need time for the supplier to rework and for a re-inspection if required. Build this into your shipping timeline.
