China Pre-Shipment Inspection Checklist for Buyers | LUYA
Use this China pre-shipment inspection checklist to verify quantity, workmanship, specifications, function, packaging and shipping marks before final payment.
What Should Be Included in a China Pre-Shipment Inspection Checklist?
Your supplier says the order is complete and asks you to pay the remaining balance.
They send several photographs showing neatly packed cartons and finished products. Everything appears ready for shipment.
But the photographs do not tell you:
- Whether the full quantity has been completed
- Whether the products match the approved sample
- Whether dimensions and materials are correct
- Whether the products function properly
- Whether defects are hidden inside the cartons
- Whether labels and barcodes are accurate
- Whether the packaging can survive international transportation
- Whether the inspected goods will be the goods actually shipped
A pre-shipment inspection helps answer these questions before the buyer releases final payment and the goods leave China.
However, an inspection is only as useful as the checklist behind it.
A generic checklist may identify obvious workmanship problems but miss the technical, commercial and packaging requirements that matter most to your order.
This guide explains what overseas buyers should include in a China pre-shipment inspection checklist and how to turn the inspection result into a practical shipment decision.
What Is a Pre-Shipment Inspection?
A pre-shipment inspection, often called a PSI or final random inspection, is normally conducted when production is substantially complete and enough products have been packed for representative sampling.
The inspector visits the factory or warehouse and compares selected products against the buyer’s approved requirements.
A pre-shipment inspection may check:
- Production completion
- Order quantity
- Product identity
- Workmanship
- Dimensions
- Materials
- Color and finish
- Assembly
- Function
- Performance
- Accessories
- Labels
- Barcodes
- Packaging
- Carton markings
- Shipment readiness
The exact inspection scope should be agreed before the inspector arrives.
Why a Generic Inspection Checklist Is Not Enough
A standard inspection company may have a general checklist for furniture, electronics, machinery, clothing or consumer goods.
That checklist can provide a starting point, but it does not automatically contain your product requirements.
For example, an inspector may confirm that an electrical product powers on but may not know:
- Required input voltage
- Output performance
- Operating temperature
- Communication protocol
- Component brand
- Protection settings
- Safety limits
- Required accessories
- Market-specific labeling
Likewise, an inspector may verify that a product is the correct color without checking whether the material grade, thickness or internal component has changed.
The buyer must convert the purchase agreement into measurable inspection criteria.
Documents to Prepare Before the Inspection
The inspection checklist should be built from the documents used to approve and manufacture the order.
Provide the inspector with:
- Purchase order
- Signed contract
- Proforma invoice
- Product specification
- Technical drawings
- Bill of materials, where relevant
- Approved sample information
- Approved product photographs
- Color references
- Packaging artwork
- Label files
- Barcode list
- User manual
- Required certificates
- Test requirements
- Previous inspection findings
- Approved change orders
- Defect classifications
- Sampling and acceptance criteria
The inspector should receive the final approved versions.
If the buyer, supplier and inspector use different versions of a specification, the inspection result may be disputed even when the physical findings are correct.
1. Purchase-Order and Product Verification
The first section should confirm exactly what is being inspected.
Record:
- Buyer
- Supplier
- Factory
- Factory address
- Purchase-order number
- Product name
- Model or SKU
- Order quantity
- Inspection date
- Production status
- Quantity completed
- Quantity packed
- Carton quantity
- Inspector arrival and departure time
Verify that the product model and description match the purchase order.
This sounds basic, but factories sometimes present:
- A different model
- Goods from another customer
- Only the best completed units
- Incomplete quantities
- Products made at another facility
- Units that have not completed final testing
The report should clearly state what was available and what could not be inspected.
2. Production-Completion Status
Before conducting a final random inspection, determine whether enough goods have been completed and packed.
The checklist should record:
- Percentage of production completed
- Percentage packed
- Unfinished quantity
- Rework quantity
- Rejected quantity
- Goods stored at another location
- Missing components or accessories
If production is incomplete, the available sample may not represent the entire order.
For example, the factory may present the first 60% of production while the remaining units are being manufactured under time pressure. Inspecting only the early production cannot confirm the quality of the later units.
The report should not describe an incomplete order as fully ready for shipment.
3. Quantity Verification
Verify:
- Total units completed
- Units per carton
- Number of cartons
- Product variants
- Colors
- Sizes
- Models
- Spare parts
- Free accessories
- Promotional materials
- Replacement units
Where a full count is not practical, the report should explain how the quantity was verified.
Special attention is needed when an order contains several SKUs. A correct total quantity can still hide shortages in one model and excess units in another.
Compare the physical count with:
- Purchase order
- Packing list
- Carton markings
- Product labels
- Warehouse records
4. Sampling Plan and Acceptance Criteria
Most pre-shipment inspections use sampling rather than checking every unit.
The checklist should define:
- Lot size
- Inspection level
- Sample size
- Acceptance standard
- Critical-defect limit
- Major-defect limit
- Minor-defect limit
The buyer and supplier should agree on the sampling and acceptance method before production is completed.
Critical Defects
A critical defect may create a safety risk, violate a mandatory requirement or make the product dangerous or unlawful to use.
Examples may include:
- Exposed electrical conductors
- Missing safety protection
- Sharp edges causing injury
- Incorrect safety warning
- Serious structural failure
- Use of a prohibited material
Depending on the product and agreed standard, the acceptance level for critical defects may be zero.
Major Defects
A major defect significantly affects function, performance, appearance, saleability or expected use.
Examples may include:
- Product does not function
- Incorrect dimensions affecting assembly
- Wrong material
- Missing component
- Serious color difference
- Damaged packaging exposing the product
- Incorrect model or configuration
Minor Defects
A minor defect does not normally prevent use but departs from the approved quality standard.
Examples may include:
- Small surface marks
- Slight cosmetic inconsistency
- Minor printing variation
- Non-critical packaging imperfections
Defect classifications should be product-specific. The same issue may be minor for one product but major or critical for another.
5. Approved Sample Comparison
If an approved sample exists, identify it clearly.
The checklist should record:
- Sample number
- Approval date
- Approved version
- Person who approved it
- Features controlled by the sample
- Written specifications that override the sample
Compare mass-production units with the approved sample for:
- Overall appearance
- Materials
- Dimensions
- Weight
- Color
- Finish
- Construction
- Components
- Function
- Branding
- Packaging
Do not rely only on the phrase “same as approved sample.”
The checklist should convert important sample features into measurable criteria whenever possible.
6. Product Dimensions and Weight
List every dimension that affects:
- Function
- Compatibility
- Installation
- Packaging
- Shipping
- Customer acceptance
For each measurement, record:
- Target value
- Permitted tolerance
- Measuring tool
- Number of units tested
- Actual results
Depending on the product, measurements may include:
- Length
- Width
- Height
- Thickness
- Diameter
- Hole position
- Weight
- Component spacing
- Cable length
- Carton dimensions
A target dimension without a tolerance is incomplete.
For example, “100 mm” does not tell the inspector whether 99.5 mm or 102 mm is acceptable.
7. Materials and Components
Confirm the materials and components that create the highest risk.
The checklist may include:
- Material type
- Material grade
- Thickness
- Density
- Composition
- Component brand
- Component model
- Country of origin, if required
- Supplier-approved alternatives
- Batch number
- Certification marking
Some material characteristics cannot be confirmed visually.
If the material requires laboratory analysis or specialized equipment, arrange that separately rather than assuming the pre-shipment inspector can verify it.
For important components, photographs of external appearance may not be enough. The inspection plan may require opening selected units, reviewing traceability records or verifying component markings.
8. Workmanship and Visual Inspection
Create a defect list based on the product.
Possible workmanship checks include:
- Scratches
- Dents
- Cracks
- Deformation
- Rust
- Contamination
- Uneven coating
- Poor welding
- Loose fasteners
- Gaps
- Sharp edges
- Excess adhesive
- Incorrect assembly
- Misaligned parts
- Poor printing
- Color variation
- Damaged connectors
- Exposed wires
- Missing protective parts
Photographs should show both the defect and its location on the product.
Avoid vague comments such as “quality is not good.” The report should describe the defect, affected quantity and classification.
9. Functional Testing
Functional testing should reflect how the customer will actually use the product.
The checklist should state:
- Test method
- Test equipment
- Test duration
- Sample quantity
- Expected result
- Pass/fail criteria
Possible functional checks include:
- Power-on test
- Control operation
- Button response
- Moving-part operation
- Assembly and fit
- Load test
- Leak test
- Charging or discharge function
- Connectivity
- Alarm function
- Locking mechanism
- Operating noise
- Temperature behavior
- Software or display operation
A brief power-on test may not reveal intermittent or long-duration problems.
If reliability is important, additional aging, endurance or laboratory testing may be required before shipment.
10. Safety Checks
Safety checks should be based on the product and destination market.
They may include:
- Electrical insulation
- Grounding
- Polarity
- Fuse or protection device
- Sharp points and edges
- Stability
- Structural security
- Warning labels
- Protective covers
- Emergency functions
- Flammability information
- Child-safety features
- Required safety accessories
A general product inspection is not automatically a certification assessment.
The inspector can check visible safety features and conduct agreed field tests, but formal regulatory compliance may require laboratory testing, technical files and valid certification.
11. Branding, Printing and Artwork
Check:
- Logo
- Brand name
- Model number
- Product color
- Printing position
- Font and spelling
- Label dimensions
- User instructions
- Warning text
- Rating label
- Country-of-origin marking
- Packaging artwork
Compare the physical product with final approved artwork.
Small spelling mistakes or incorrect contact information may make an entire shipment difficult to sell, even when the products function correctly.
The buyer should provide digital artwork or approved reference files rather than asking the inspector to judge branding from memory.
12. Barcode and Label Verification
The checklist should identify every required label and barcode.
Verify:
- Barcode type
- Barcode number
- Scan result
- SKU
- Model
- Serial number
- Batch number
- Product rating
- Carton label
- Shipping label
- Warning label
- Language
- Placement
- Adhesion
- Print clarity
A barcode that looks correct may still contain the wrong data.
Require scanning where barcode accuracy is commercially important.
If serial numbers must be unique or matched to a database, define how that will be checked.
13. Accessories, Manuals and Spare Parts
Confirm that each product or carton contains the correct:
- Accessories
- Cables
- Chargers
- Adapters
- Fasteners
- Tools
- Mounting parts
- Remote controls
- User manuals
- Warranty cards
- Spare parts
The checklist should state:
- Required quantity
- Model or specification
- Packaging location
- Language
- Compatibility
Missing low-cost accessories can generate expensive customer complaints after import.
14. Packaging Inspection
Packaging should protect the product through handling, storage and international transportation.
Check:
- Inner packaging
- Protective film
- Foam or inserts
- Plastic bags
- Moisture protection
- Product separation
- Carton strength
- Carton closure
- Strapping
- Pallet condition
- Corner protection
- Wooden packaging
- Packaging cleanliness
- Product movement inside the carton
Confirm that packaging materials match the approved specification.
For heavy, fragile or moisture-sensitive goods, the inspection plan may also include:
- Drop testing
- Vibration considerations
- Moisture indicators
- Desiccants
- Reinforced cartons
- Pallet loading
- Fumigation or wood-treatment markings where applicable
15. Carton Dimensions and Weight
Measure and record:
- Carton length
- Carton width
- Carton height
- Net weight
- Gross weight
- Units per carton
- Total carton quantity
These details affect:
- Freight quotation
- Container planning
- Warehouse handling
- Import documentation
- Customer distribution
Large differences between quoted and actual carton dimensions can increase transportation costs.
Compare inspection measurements with the packing list and supplier’s shipping information.
16. Shipping Marks and Export Information
Verify the required shipping marks, which may include:
- Buyer name
- Purchase-order number
- Product model
- Carton number
- Quantity
- Gross weight
- Net weight
- Dimensions
- Country of origin
- Handling symbols
- Destination
- Batch information
Check that the shipping marks are:
- Correct
- Legible
- Consistent
- Positioned correctly
- Resistant to normal handling
Incorrect markings may create warehouse confusion or customs and delivery problems.
17. Product and Carton Photographs
The inspection report should include clear photographs of:
- Factory or warehouse
- Available goods
- Random carton selection
- Opened cartons
- Product overview
- Product details
- Measurements
- Functional tests
- Defects
- Labels
- Barcodes
- Accessories
- Inner packaging
- Outer cartons
- Shipping marks
- Packed goods
Photographs should support the written findings, not replace them.
A single photograph of a perfect product does not represent the entire sampled quantity.
18. Inspection Result and Buyer Decision
The final report should clearly summarize:
- Production completion
- Quantity result
- Defect count
- Test results
- Packaging result
- Unverified items
- Deviations
- Overall conclusion
- Required corrective actions
However, the inspector’s “pass” or “fail” result does not replace the buyer’s commercial decision.
The buyer may:
- Approve shipment
- Approve with documented exceptions
- Require sorting
- Require rework
- Require replacement
- Request additional testing
- Arrange reinspection
- Delay final payment
- Reject the shipment under the contract
The buyer should consider the defect type, customer requirements, delivery schedule and contractual rights.
19. Corrective Action and Reinspection
If the inspection identifies problems, request a written corrective-action plan containing:
- Defect description
- Affected quantity
- Root cause
- Immediate containment
- Repair or replacement method
- Responsible person
- Completion date
- Prevention measure
Do not treat factory photographs of repaired units as proof that the entire order has been corrected.
Reinspection may be necessary to verify:
- Rework
- Replacement
- Sorting
- New production
- Updated packaging
- Correct labels
- Full-order completion
The contract should state who pays for reinspection when the original inspection fails.
What a Pre-Shipment Inspection Cannot Confirm
A standard PSI may not confirm:
- Long-term reliability
- Every unit in the shipment
- Hidden internal defects
- Chemical composition
- Full regulatory compliance
- Authenticity of all electronic components
- Performance under extended field use
- Products completed after the inspection
- Goods substituted after the inspector leaves
- Damage during loading or transportation
These risks may require:
- Supplier audit
- Raw-material testing
- Laboratory testing
- During-production inspection
- 100% inspection
- Reliability testing
- Container-loading supervision
- Ongoing production monitoring
The correct quality-control plan depends on the product and consequences of failure.

Our role is to connect the contract, specifications, production process, inspection findings and next action so the overseas buyer can make a better-informed release decision.
Conclusion
A useful China pre-shipment inspection checklist must be specific to the product and order.
It should define:
- What documents control the inspection
- What quantity must be available
- How samples will be selected
- Which defects are critical, major or minor
- What dimensions, materials and functions must be checked
- What packaging and labeling are required
- What happens if the inspection fails
- Whether payment and shipment may proceed
A generic visual inspection may detect obvious defects. It cannot protect requirements that were never documented or added to the checklist.
The inspection should begin with a clear purchase specification—not when the inspector arrives at the factory.

Frequently Asked Questions
When should a pre-shipment inspection be conducted?
It is normally conducted when production is substantially complete and enough goods are packed for representative sampling. Inspecting too early may leave later-produced goods unchecked.
Does a passed inspection guarantee that every unit is defect-free?
No. Most pre-shipment inspections use sampling. A passed result means the inspected sample met the agreed acceptance criteria; it does not guarantee every unit or eliminate hidden defects.
What documents should I send to the inspector?
Provide the purchase order, final specifications, drawings, approved sample details, packaging artwork, label files, required tests, defect classifications and approved changes.
What is the difference between critical, major and minor defects?
Critical defects may create safety or serious compliance risks. Major defects significantly affect function, saleability or expected use. Minor defects represent smaller departures that normally do not prevent use. Definitions should be customized for the product.
Should I pay the final balance before inspection?
Payment terms depend on the contract, but buyers often retain commercial leverage by connecting final payment to production completion, inspection results and confirmed shipping arrangements.
What should I do if the inspection fails?
Request defect details, root-cause analysis and a corrective-action plan. Depending on the findings, require sorting, rework, replacement, additional testing or reinspection before approving shipment.
Can a pre-shipment inspection verify product certification?
The inspector may check labels, documents and visible product details, but a standard PSI does not replace laboratory testing or formal certification review.
Can LUYA use my existing checklist?
Yes. LUYA can review your existing checklist, compare it with the purchase documents and add missing product, packaging or order-control requirements where appropriate.
