A pre-shipment inspection verifies quantity, print quality, color accuracy, structural fit, finishing and packing before goods leave the factory. In our Dongguan facility, we complete this checklist for every shipment so buyers receive what they ordered.
The final inspection is your last chance to catch a problem before boxes are loaded onto a truck or container. This checklist walks through the key checks and explains why each one matters.
When to conduct the inspection
Pre-shipment inspection should happen after 100% of production is complete and at least 80% of goods are packed. Inspecting too early can miss late-batch defects. Inspecting after goods have left the factory is too late.
Sampling plan
For large orders, use AQL sampling rather than checking every unit. A common plan for packaging is:
- General inspection level II
- AQL 2.5 for major defects
- AQL 4.0 for minor defects
The sample size depends on the total lot size. For example, a lot of 5,000 units usually requires inspection of 200 units under general level II.
Inspection checklist
1. Quantity
- Count total units produced.
- Compare to purchase order quantity.
- Check if over- or under-shipment is within agreed tolerance (usually ±2%).
- Verify master carton quantities and pallet counts.
2. Artwork and print
- Compare printed artwork to approved PDF.
- Check for missing text, graphics or barcodes.
- Verify print position and orientation.
- Inspect for smudging, scuffing or ink offset.
3. Color accuracy
- Compare production sample to approved color standard.
- Measure critical colors with a spectrophotometer if specified.
- Confirm Delta E is within tolerance.
- Check color consistency across the sample.
For more on color measurement, see Delta E Color Accuracy: How We Match Your Brand Colors.
4. Dimensions and structure
- Measure length, width and height against drawing.
- Check fold lines, creases and glue flaps.
- Assemble boxes and verify fit.
- Confirm lids close properly and inserts sit correctly.
5. Finishing
- Check lamination for bubbles, wrinkles or delamination.
- Inspect foil stamping for completeness and adhesion.
- Verify embossing depth and alignment.
- Confirm spot UV registration and gloss level.

6. Material
- Verify substrate matches specification.
- Check GSM or caliper if required.
- Confirm FSC or other certifications if claimed.
- Inspect for visible defects in paper or board.
7. Packing
- Confirm inner packing (polybag, tissue, divider).
- Check master carton strength and labeling.
- Verify shipping marks and barcode labels.
- Confirm pallet configuration and wrapping.
8. Workmanship
- Look for glue squeeze-out, torn edges or crushed corners.
- Check that ribbons, magnets and closures function properly.
- Inspect for dust, fingerprints or foreign objects inside boxes.
Inspection checklist summary table
| Check | What to verify | Common defect |
|---|---|---|
| Quantity | Total units, carton counts | Short shipment |
| Artwork | Text, graphics, barcodes | Missing print, wrong version |
| Color | Match to standard, Delta E | Color shift |
| Dimensions | Size, fit, assembly | Out of tolerance, poor fit |
| Finishing | Lamination, foil, emboss, UV | Bubbles, misregistration |
| Material | Substrate, GSM, certification | Wrong material |
| Packing | Cartons, labels, pallets | Damaged outer cartons |
| Workmanship | Clean assembly, functional parts | Glue stains, loose parts |
Real example: catching a packing error
During a pre-shipment inspection for a jewelry brand, we noticed that one master carton contained 48 units instead of the specified 50. The packing team had switched to a smaller inner box mid-run without updating the count. We repacked the carton and updated the packing instructions. The error never reached the customer.
Defect classification
Before inspection, agree on what counts as a defect:
| Type | Example | Typical action |
|---|---|---|
| Critical | Wrong artwork, unsafe material | Reject lot |
| Major | Color out of tolerance, broken box | Rework or sorted acceptance |
| Minor | Slight scuff, minor glue spot | Accept within AQL limit |
Who should do the inspection?
The factory can perform internal pre-shipment inspection. Buyers can also send their own QC staff or hire a third-party inspector. For high-value orders, third-party inspection adds an extra layer of confidence.
For broader quality systems, read Quality Control for Packaging: A Buyer’s Checklist.
What happens if defects are found?
If the inspection fails, the factory should:
- Sort defective units.
- Rework or replace them.
- Re-inspect the corrected lot.
- Provide a corrective action report.
The buyer and supplier should agree in advance on who pays for rework and re-inspection.
Documentation
After inspection, keep records of:
- Inspection date and sample size
- Photos of any defects
- Measurement data
- Inspector name
- Pass/fail result
- Corrective actions
These records protect both buyer and supplier if questions arise later.
Conclusion
A pre-shipment inspection is the final gate between production and delivery. By checking quantity, print, color, structure, finishing, material and packing, you avoid the cost and frustration of receiving defective goods. At Zhengyang, we perform structured pre-shipment inspections in our Dongguan facility and welcome buyer or third-party verification.
