Pre-Shipment Inspection Checklist for China Orders: What to Define Before the Inspector Arrives

Use a pre-shipment inspection when you need an independent check of a production lot before the goods leave the factory — especially when product quality, labeling, packaging, quantity, or workmanship problems would be difficult or expensive to correct after shipment.

But the inspector should not arrive with only an instruction to:

“Check whether the products are good.”

Before the inspection, define:

What to inspect → Which specification controls → Which physical reference applies → Which drawings and tolerances apply → What counts as a defect → How the lot will be sampled → How much production must be complete → What happens if the result is not acceptable

Many inspection providers schedule a PSI when most of the order is complete and enough finished goods are available for representative sampling. QIMA, for example, states that its PSI is conducted when at least 80% of the production order is complete. (QIMA) That 80% threshold is QIMA’s stated service condition, not a universal rule for every product, inspection provider, or contract.

A PSI is a point-in-time, sample-based inspection. It can provide evidence about the inspected lot under the defined scope. It does not guarantee that every unit is defect-free, replace laboratory testing, prove supplier reliability, or automatically resolve regulatory compliance questions.

A PSI is particularly useful when:

• this is the first bulk order with a supplier;
• the approved sample is important to the final product standard;
• product appearance or workmanship can vary in mass production;
• artwork, spelling, labeling, or packaging errors would be costly after shipment;
• the order value is significant;
• the balance payment is contractually linked to shipment or inspection milestones;
• the goods will ship internationally and rework after delivery would be expensive;
• the buyer cannot inspect the goods in person before shipment;
• previous production showed quality inconsistencies;
• multiple SKUs, sizes, colors, or packaging variants must be checked.

A PSI is not always the right first inspection.

If the highest-risk issue happens earlier in production — for example raw-material substitution, first-piece setup, a critical manufacturing process, or unauthorized subcontracting — consider an Initial Production Check or During Production Inspection as well.

QIMA distinguishes these stages: initial checks can occur before or during the first 20% of production, during-production checks occur while production is underway, and PSI is generally used near completion. (QIMA Initial Production Check)

The question is not:

“Do I need an inspection?”

It is:

“At which production stage can the problem I care about still be detected and corrected?”

Do not schedule the inspector only by calendar date.

Confirm the factory's actual production status.

Before the visit, record:

If the inspector arrives too early, the available units may not represent the final lot.

If the inspection is scheduled too late — after goods have already shipped or become difficult to rework — the inspection loses much of its preventive value.

The inspector needs a controlled product standard.

Provide the final approved revision, not several conflicting versions spread across email, chat, and attachments.

The inspection pack should state:

• product / SKU;
• specification revision;
• materials;
• dimensions;
• tolerances;
• construction;
• color / finish;
• functionality requirements;
• included accessories;
• labeling;
• packaging;
• required on-site tests;
• approved deviations.

If the final inspection standard is unclear, a technically accurate inspection report can still produce an unusable sourcing decision.

The inspector should evaluate the goods against your defined requirements, not invent the product standard on the day of inspection.

If an Approved Sample or Golden Sample is part of the production standard, identify it clearly.

Record:

• sample ID;
• product revision;
• approval date;
• photos where useful;
• approved deviations;
• who holds the physical sample;
• whether the factory and inspector can access the same reference.

The sample should be used together with the written specification.

Do not rely on:

“Please make the bulk goods exactly like the sample.”

when key measurable requirements are not documented.

The related SourcingX guide, How to Evaluate Supplier Samples Before Placing a Bulk Order, uses the same production-control sequence:

Written Specification → Production-Representative Sample → Approved / Golden Sample → Pilot Order where needed → Change Control → Bulk Production → Production / Pre-Shipment Inspection. (SourcingX Sample Guide)

For measurable characteristics, provide the exact controlled reference.

Depending on the product, this may include:

• engineering drawings;
• dimension tables;
• measurement points;
• tolerance ranges;
• weight limits;
• color references;
• assembly requirements;
• fit / gap limits;
• performance criteria.

Avoid instructions such as:

“Size should be normal.”

or:

“Make sure the fit is good.”

Replace them with criteria an inspector can actually check.

Small artwork errors can affect an entire production lot.

The inspection pack should include approved versions of:

• logo artwork;
• printed text;
• spelling;
• font or layout requirements where relevant;
• barcodes;
• care labels;
• warning labels;
• product labels;
• retail packaging;
• inserts / manuals;
• inner cartons;
• master cartons;
• carton markings;
• assortment rules.

This is particularly important for products where a typo, wrong barcode, incorrect country-of-origin mark, or wrong size label can make otherwise usable goods difficult to sell.

QIMA lists artwork, labels, product dimensions, packaging, quantity, workmanship, and functional checks among common PSI inspection areas. (QIMA)

Do not assume “PSI” means the same checklist for every product.

Define which checks matter for the order.

If a requirement cannot be verified during a PSI — for example chemical composition, electrical safety certification, or long-duration reliability — use the appropriate testing or verification method separately.

The inspector needs to know what counts as a defect and how serious it is.

A common framework uses:

• Critical defect — a defect that may create a serious safety, legal, or fundamental-use problem;
• Major defect — a defect likely to make the product unacceptable for its intended use or materially affect customer acceptance;
• Minor defect — a smaller departure from the agreed standard that does not materially affect normal use.

These definitions should be adapted to the product.

For example, a spelling error on decorative internal packaging may be treated differently from the same error on a legally required warning label.

Do not leave important defect classification to be negotiated only after the inspection report arrives.

A PSI normally checks a sample of the production lot rather than every unit.

ISO 2859-1:2026 defines acceptance-sampling schemes indexed by Acceptance Quality Limit (AQL) for lot-by-lot inspection by attributes. (ISO) Different providers or contracts may use different sampling standards or plans, so specify the applicable standard or plan rather than assuming that “AQL” alone defines the inspection.

Before inspection, agree where applicable:

• lot size;
• inspection level;
• sampling plan;
• sample size;
• defect categories;
• acceptance / rejection limits;
• whether different checks use different sample quantities.

Do not copy a generic AQL number from another product without considering your own product and risk requirements.

The important sourcing principle is:

Sampling rules and defect limits should be defined before the result is known.

Otherwise the buyer and supplier may end up negotiating whether defects are acceptable only after they have already appeared.

What Should the Inspection Result Tell You?

The inspection report should help answer:

• Was the required quantity available?
• Was the lot ready for representative inspection?
• Which units were sampled?
• Did the sampled products match the defined specification?
• What defects were found?
• How were defects classified?
• Did measurements and functional checks pass?
• Were artwork and labels correct?
• Was packaging consistent with the requirement?
• Were there any checks that could not be completed?
• Did the inspected sample meet the agreed acceptance criteria?

A report should make exceptions and uncompleted checks visible, rather than turning every item into a simple green status.

Inspection providers may report findings and an overall pass / fail result according to the agreed inspection plan.

For the buyer's commercial decision, use four practical statuses:

A Pass does not mean every unit in the lot was inspected or that no defect exists anywhere in the shipment.

A Fail does not automatically define the legal remedy. The commercial response depends on the contract, the nature of the defect, rework feasibility, timing, and agreed quality terms.

Before inspection, decide how a failed result will be handled.

Possible next steps include:

Fail → Root cause / sorting / rework → Evidence of correction → Re-inspection where appropriate → Buyer decision

For each failed item, record:

Possible evidence may include:

• rework records;
• updated photos;
• corrected artwork;
• new measurement data;
• replacement quantity;
• revised packing records;
• re-inspection report.

Do not accept a simple message such as:

“We fixed everything.”

when the defect was significant enough to fail the inspection.

The appropriate confirmation should match the severity and nature of the finding.

A PSI result should connect to the commercial process defined in the contract or PO.

Before moving forward, check:

• The complete inspection report has been reviewed.
• Critical findings are understood.
• Major defects are within the agreed acceptance criteria or have been corrected.
• Any approved deviation is documented.
• Required rework evidence has been received.
• Re-inspection has been completed where appropriate.
• Final quantity and assortment are understood.
• Packaging and shipping marks meet the agreed requirement.
• Outstanding laboratory / compliance results have been addressed separately where required.
• The shipment is tied to the correct supplier / order / product revision.
• The payment milestone in the contract or PO has actually been satisfied.

Do not interpret this checklist as a universal rule to withhold or release payment.

Payment rights and obligations depend on the agreed contract and payment terms. The PSI provides evidence for that decision; it does not replace the contract.

This distinction follows the same evidence principle as sample approval:

A sample tells you about the sample. A PSI tells you about an inspected sample from the production lot. Neither should be expanded beyond the evidence actually reviewed.

A. Before booking

B. Product standard

C. Artwork and packaging

D. Inspection method

E. After inspection

Pre-shipment inspection is a product quality-control activity.

SourcingX does not replace the inspector, laboratory, quality engineer, or physical inspection process.

SourcingX can support the surrounding supplier decision by helping buyers review available company, factory, platform, public, and trade evidence and identify unresolved supplier information before the buyer increases its commercial commitment.

A useful division of responsibility is:

SourcingX / supplier due diligence:
Who is the supplier, what available evidence supports its company and factory claims, and what remains unresolved?

Sample / Golden Sample:
What product standard has the buyer approved?

Pre-Shipment Inspection:
Does the inspected production sample meet the predefined product and acceptance criteria before shipment?

These steps complement each other. They are not substitutes for one another.

Bottom Line

A pre-shipment inspection works best when the buyer defines the evidence standard before the inspector arrives.

The practical sequence is:

Final Specification → Approved / Golden Sample → Inspection Scope → Defect Definitions → Sampling / Acceptance Criteria → Production Readiness → PSI → Corrective Action / Re-inspection → Balance / Shipment Decision

Do not ask only:

“Did the inspector pass the shipment?”

Ask:

“What was inspected, against which standard, using which sampling and acceptance criteria, what was not checked, and what remains unresolved before the goods ship?”
