Pre-Shipment Quality Control
Your final gate before goods ship
By the time goods are packed and ready for shipment, payment and freight timelines are tight. Pre-shipment quality control (PSI) is often your last realistic opportunity to stop a defective batch before it becomes a warehouse and customer problem.
"Pre-shipment quality control is a final on-site verification performed at 80% production completion. An inspector randomly samples goods against your checklist, checks packaging and labeling, and documents conformance to your standards before shipment is released."
When to Schedule Pre-Shipment QC
At 80% production completion — when enough goods are finished and packed to sample, but time remains to address defects before shipment.
This timing balances having enough finished units to inspect meaningfully with having enough time to correct problems if needed.
In-Depth Guide
What does a pre-shipment inspection check?
A solid PSI checks quantity, workmanship, specifications, packaging, and functional performance before shipment release.
1. Quantity verification
2. Workmanship and visual quality
3. Specification conformity
4. Packaging and labeling
5. Functional testing
How AQL sampling works
PSI normally relies on random sampling, not 100% checking. The sample size and pass-fail logic depend on the agreed AQL level.
Sample size depends on lot size and AQL level.
Defects found in the sample are categorized by severity.
The lot passes or fails based on defect count versus tolerance.
Critical, major, and minor defects
These definitions must be agreed before inspection, or the report loses decision-making value.
Critical defect
Major defect
Minor defect
What a PSI report should deliver
Observed quantity versus declared quantity
Defect findings by severity
Measurements and specification results
Packaging and labeling findings
Photo evidence from the site visit
A clear pass, fail, or pending recommendation
When PSI matters most
New suppliers or unstable process control
Large-value or brand-sensitive orders
Marketplace inventory with strict label rules
Orders where final payment depends on shipment readiness
How to use PSI well
- 1
Lock your specs and defect criteria before production ends.
- 2
Book PSI when goods are substantially complete and packed.
- 3
Review the report before freight cutoff and payment release.
- 4
Decide to ship, rework, reinspect, or hold the lot.
What PSI does not do
Buyers sometimes expect PSI to solve every sourcing risk. It does not.
PSI does not replace:
- Supplier due diligence
- Factory audits for capability
- Product testing for regulatory compliance
- In-process control during manufacturing
- Engineering review of product design
PSI is a final gate, not a full sourcing strategy. A shipment can pass PSI and still hide compliance, supplier, or production-capability risks.
When PSI alone is not enough
New factory or weak process control
Add a factory audit and during-production inspection.
Technical or regulated product
Add laboratory testing and compliance review on top of PSI.
Tight launch deadlines
Use inline or mid-production checks before the final stage.
Common Buyer Mistakes with PSI
Booking PSI without a working checklist
If the inspector doesn't know your standards, the report may be formally complete but weak for decision-making.
Using vague specifications
Any dispute hinges on the quality of your original standard.
Ignoring packaging and labeling
Many expensive problems start there, not in the product itself.
Treating PSI as a formality for the supplier
The inspector should reflect your risk threshold, not just document shipment status.

Pre-Shipment Inspection — Frequently Asked Questions
- How much does a pre-shipment inspection cost?
- ECOMCARE pre-shipment inspections start from $200 per inspection. The final price depends on the scope and location. Scheduling is confirmed within 24 hours of request.
- When should a pre-shipment inspection be booked?
- Book PSI when approximately 80% of production is complete and a meaningful share of goods is packed and ready. This gives enough finished units to sample while leaving time to correct findings before the shipment is released.
- What does a pre-shipment inspector check?
- A pre-shipment inspector checks quantity, workmanship, packaging, labeling, and compliance against the buyer's specifications. Inspectors use AQL sampling tables to determine how many units to examine.
- Can I watch the pre-shipment inspection live?
- Yes. ECOMCARE offers live video streaming during inspections so buyers can observe the process in real time, ask questions, and review findings before the report is issued.
- What happens if the inspection fails?
- You can hold final payment and require the factory to sort, rework, or replace defective units before re-inspection. The report serves as documented evidence.
- How does PSI differ from a factory audit?
- A factory audit evaluates the supplier's competency before production begins. PSI checks finished goods at the end of production. They address different risks and are often used together.
