An Indian homeware exporter has 8,000 ceramic pieces ready for a buyer in the UK. The cartons are packed, the freight booking is confirmed, and the shipment is due to leave in two days. Then the buyer’s inspector opens a sample and finds chipped edges, incorrect carton labels, and a product count that does not match the purchase order.
Catching those problems before dispatch is inconvenient. Discovering them after the goods reach another country is considerably more expensive.
That is the purpose of a pre-shipment inspection (PSI): checking a shipment before it leaves the exporter or manufacturer so that problems with quality, quantity, packaging, labelling, specifications, or required documentation can be identified while there is still time to correct them.
For exporters, the inspection can be a contractual quality-control step, a buyer requirement, part of a letter of credit, or—depending on the destination country and product—a regulatory requirement. The checklist therefore needs to reflect the actual goods, contract, destination market, and inspection requirement rather than follow one generic template.
This guide explains how pre-shipment inspection works, when it is required, what to include in a pre-shipment inspection checklist, how AQL sampling is used, and what exporters should do when a shipment fails inspection.

TL;DR
- A pre-shipment inspection checks goods before dispatch for factors such as quantity, workmanship, specifications, packaging, labelling, functionality, and required documentation.
- PSI can be a buyer-led quality check, a contractual or letter-of-credit requirement, or a government-mandated inspection for particular imports; it is not compulsory for every export.
- Inspectors commonly use Acceptance Quality Limit (AQL) sampling rather than inspecting every unit, with the sample size and acceptance criteria agreed for the product and risk involved.
- Exporters should complete inspection early enough to correct defects, retain the inspection report, and ensure the approved goods, packaging, documents, and quantities are the ones actually shipped.
What is a pre-shipment inspection?
A pre-shipment inspection is an examination of goods before they are dispatched to the buyer, usually after most or all production has been completed and the goods are sufficiently packed for the inspector to assess the actual shipment.
The inspection can verify whether the goods match agreed requirements such as:
- product specifications
- purchase-order quantities
- workmanship
- dimensions and weight
- colour and appearance
- functionality
- safety-related requirements
- packaging
- shipping marks
- labels
- barcodes
- contractual requirements
- required certificates or documents
The inspection normally ends with a report recording what was checked, the sample used, defects found, photographs, test results where applicable, and an overall pass, fail, or other agreed outcome.
For the exporter, this creates a final quality-control point before the shipment becomes much harder and more expensive to correct.
Is pre-shipment inspection mandatory for exports?
Not for every export.
Whether PSI is required depends on the transaction.
A pre-shipment inspection may be required because:
- the buyer included it in the sales contract or purchase order
- a letter of credit requires an inspection certificate
- the importer wants an independent quality check before accepting shipment
- the destination country requires PSI for a particular category or value of imports
- the goods are subject to product-specific conformity, sanitary, safety, or other inspection requirements
This distinction matters because the phrase pre-shipment inspection is used for more than one kind of inspection.
Buyer or commercial pre-shipment inspection
A buyer may appoint an independent inspection company to check whether the goods match the order before shipment.
This is primarily a commercial quality-control measure.
For example, a fashion retailer sourcing 20,000 shirts from India might require an inspector to verify measurements, stitching, colour, quantities, packing ratios, carton markings, and workmanship before the goods are released.
Government-mandated pre-shipment inspection
Some importing countries require certain goods to be inspected before they leave the exporting country.
Under the WTO framework, government-mandated pre-shipment inspection can involve verification of matters such as quality, quantity, price, exchange rate, financial terms, or customs classification.
The precise requirement varies by country and product and can change over time.
An exporter should therefore check the destination-country rules and instructions from the importer rather than assuming an inspection certificate is always required—or never required.
When should a pre-shipment inspection take place?
A PSI should happen late enough for the inspector to assess the actual production run, but early enough for the supplier to correct problems before dispatch.
In commercial quality-control practice, inspections are commonly scheduled when production is substantially complete and the goods are largely or fully packed.
There is no universal percentage that applies to every shipment.
The appropriate timing depends on factors such as:
- product type
- production cycle
- packing status
- shipment deadline
- buyer requirements
- inspection-company procedure
- whether laboratory testing is needed
- time required for rework if the shipment fails
If the inspection is carried out too early, the inspector may not see the finished shipment.
If it is carried out on the morning the container is due to leave, there may be no realistic time to correct anything.
Who carries out a pre-shipment inspection?
The inspection can be performed by:
- the buyer’s own quality team
- the exporter’s internal quality-control team
- an independent third-party inspection company
- an inspection body nominated under the contract
- an entity approved or mandated for the destination country’s inspection programme
Where independence is important, buyers commonly appoint a third-party inspector rather than relying entirely on the factory’s own quality checks.
The sales contract should make clear who appoints the inspector, who pays for the inspection, what standard will be used, and what happens if the shipment fails.
What should a pre-shipment inspection checklist include?
A useful pre-shipment inspection checklist follows the shipment from the purchase order through to the packed goods.
| Inspection area | What to check | Why it matters |
|---|---|---|
| Order and specifications | SKU, model, colour, size, material, drawings, approved sample | Confirms the goods match what was ordered |
| Quantity | Units, cartons, packing ratio, assortment | Prevents shortages, overages, and incorrect assortments |
| Sampling | Agreed sampling plan and AQL where applicable | Provides a structured way to inspect a representative sample |
| Workmanship | Scratches, stitching, assembly, finish, contamination, damage | Identifies visible and manufacturing defects |
| Dimensions and weight | Product size, tolerances, net/gross weight | Checks conformity with specifications |
| Functionality | Operation, performance, assembly, accessories | Confirms the product works as intended |
| Safety checks | Product-specific checks defined by the specification or applicable standard | Identifies potentially critical defects |
| Labelling and marking | Product labels, warnings, country-of-origin marks, barcodes, carton marks | Reduces compliance and receiving errors |
| Packaging | Inner packaging, cartons, sealing, protection, palletisation | Reduces transit damage |
| Documents | Purchase order, packing list, inspection requirements, certificates where applicable | Helps ensure shipment records match the goods |
| Final report | Findings, photographs, defect counts, test results, pass/fail decision | Creates a record for release or corrective action |
The checklist should be customised to the product.
An inspection for cotton garments should not look like an inspection for industrial machinery, lithium batteries, toys, food products, or ceramic tableware.
How does a pre-shipment inspection work step-by-step?
Step 1: Review the purchase order and inspection criteria
Before inspecting the goods, the inspector needs a clear reference point.
This can include:
- purchase order
- product specifications
- technical drawings
- approved samples
- packaging instructions
- colour standards
- labelling requirements
- inspection standard
- agreed AQL levels
- destination-market requirements
- letter-of-credit conditions, where relevant
Without agreed criteria, “good quality” is subjective.
A specification such as 500 ml capacity ±2%, matte black finish, logo centred within a 2 mm tolerance is inspectable. “Make sure the bottle looks good” is not.
Step 2: Verify the shipment quantity
The inspector checks whether the finished quantity matches the order and packing records.
This can include:
- number of finished units
- number of cartons
- units per carton
- size or colour assortment
- spare parts
- accessories
- promotional inserts
Suppose a buyer ordered 5,000 units in five colours, with 1,000 of each.
A factory may have produced exactly 5,000 pieces overall and still fail the order if one colour is short and another is overproduced.
Quantity inspection therefore needs to go beyond the grand total.
Step 3: Select the inspection sample
Inspecting every unit is often impractical for a large commercial shipment.
Instead, an inspector may use an acceptance sampling plan, commonly based on AQL principles, to select a sample from the lot.
The sample should be drawn across the shipment rather than taken only from the easiest cartons to reach.
This helps reduce the risk that the inspected sample is unusually good—or unusually bad—compared with the shipment as a whole.
What is AQL in pre-shipment inspection?
AQL stands for Acceptance Quality Limit. It is used in acceptance sampling to determine the sample size and the number of nonconforming items that can lead to acceptance or rejection under an agreed sampling plan.
ISO's current ISO 2859-1:2026 provides acceptance sampling plans for inspection by attributes.
AQL should not be read as a promise that exactly a particular percentage of the entire shipment is defective.
Instead, it is part of a statistical sampling system used to make an acceptance decision about a lot without inspecting every unit.
For a commercial PSI, the buyer, supplier, and inspection provider should establish matters such as:
- lot size
- inspection level
- AQL values
- defect categories
- acceptance and rejection numbers
before the inspection takes place.
What are critical, major and minor defects?
Inspection checklists commonly classify defects by severity.
Critical defects
A critical defect presents an unacceptable safety, legal, or serious usability risk under the agreed criteria.
Examples might include:
- exposed electrical wiring
- a prohibited hazardous material
- a dangerous sharp edge on a children’s product
- a safety component fitted incorrectly
A buyer may set extremely low or zero tolerance for specified critical defects.
Major defects
A major defect materially affects the product’s use, saleability, function, or compliance with the agreed specification.
Examples can include:
- a zip that does not close
- incorrect product dimensions outside tolerance
- a missing component
- incorrect branding
- a lamp that does not switch on
Minor defects
A minor defect does not normally prevent the product from being used but falls short of the agreed quality standard.
Examples can include:
- a small cosmetic mark
- slightly uneven stitching
- a minor print-position variation within an agreed range
The classification must be defined for the product.
A small scratch may be minor on industrial equipment but commercially unacceptable on a premium watch face.
How do inspectors check workmanship and appearance?
The inspector compares the sampled goods against the approved specification or reference sample.
Depending on the product, the check might cover:
- scratches
- dents
- chips
- cracks
- stains
- loose threads
- poor stitching
- colour variation
- incorrect assembly
- glue marks
- surface finish
- print quality
- missing components
- odour or contamination
- inconsistent workmanship
For the ceramic-export example, a chip on the rim might be classified differently from a slight colour variation on the base.
The checklist should define those expectations before production is finished, not after a disagreement begins.
What should be checked for dimensions, weight and specifications?
Conformity checks determine whether the product matches the agreed technical requirements.
An inspector might measure:
- length
- width
- height
- diameter
- thickness
- capacity
- net weight
- gross weight
- component dimensions
- tolerance ranges
The tools used depend on the goods and required precision.
A garment inspection might use measurement tapes and an approved size chart. A machined component may require callipers or other precision equipment.
Any measurement tolerance should come from the product specification, drawing, applicable standard, or contract rather than being invented during inspection.
What functionality tests are included in a PSI?
Function testing depends entirely on the product.
Examples include:
- switching an electrical product on and off
- checking buttons and controls
- assembling and disassembling components
- checking zips, clasps, hinges, or locks
- load testing where specified
- charging an electronic device
- checking accessories
- scanning a barcode
- verifying product software or settings where required
A PSI is not automatically a substitute for specialised laboratory testing or product certification.
Some safety, chemical, electrical, food, medical, or regulatory tests require accredited laboratories or other specific conformity-assessment procedures.
The pre-shipment checklist should therefore distinguish between tests the inspector can perform at the factory and certificates or laboratory reports that must already exist.
What should exporters check for labels and regulatory markings?
Labelling mistakes can make perfectly functional products difficult to sell or import.
The inspector may need to verify:
- product name
- model or SKU
- barcode
- batch or lot number
- country-of-origin marking
- warning labels
- care instructions
- importer information
- language requirements
- carton shipping marks
- regulatory markings where legally applicable
Do not assume that every product entering a particular market needs the same conformity mark.
For example, CE marking applies only to products covered by relevant EU legislation; it is not a generic quality mark for all products sold in Europe.
The exporter should establish the product-specific legal requirements before production and then make those requirements part of the inspection checklist.
How should packaging be inspected before shipment?
The product can pass every workmanship test and still reach the buyer damaged if the packaging is inadequate.
Packaging inspection can cover:
- inner packaging
- protective material
- carton dimensions
- carton strength
- carton quantity
- sealing
- strapping
- moisture protection
- pallet condition
- pallet configuration
- carton markings
- shipping labels
Where the buyer has specified drop tests, carton tests, pallet standards, or other packaging checks, those should be added to the inspection plan.
For fragile products, packaging inspection can be just as important as inspection of the goods themselves.
What documents should be checked during pre-shipment inspection?
The inspector should have access to the documents needed to compare the physical shipment with the commercial requirements.
Depending on the transaction, these may include:
- purchase order
- commercial invoice
- packing list
- product specifications
- approved samples
- technical drawings
- sales contract
- letter of credit
- certificates required under the contract
- testing reports
- conformity documentation
- destination-country inspection instructions
A PSI does not replace export documentation.
Its role is to help verify that the goods and relevant information align with what has been ordered or required.
What is a pre-shipment inspection report?
The pre-shipment inspection report records the inspection findings and gives the buyer or exporter evidence of what was checked.
A useful report commonly includes:
- supplier or factory details
- buyer or order reference
- date and location of inspection
- product and SKU details
- quantity presented for inspection
- sampling method
- sample size
- defect classification and counts
- measurements
- test results
- packaging findings
- labelling findings
- photographs
- deviations from specifications
- overall result
The final status might be pass, fail, pending, or another result defined by the inspection provider or buyer.
The report should make clear which findings led to that outcome.
What happens if goods fail pre-shipment inspection?
A failed PSI does not necessarily mean the entire order must be abandoned.
It means the shipment should not simply be released without addressing the findings.
The next action depends on the problem and the contract.
The exporter or manufacturer may need to:
- identify the affected goods
- separate defective units
- rework or replace them
- correct labels or packaging
- complete missing documentation
- reproduce short quantities
- carry out additional testing
- arrange a re-inspection
The buyer may agree to accept some non-conformities, request a discount, insist on rework, or reject the shipment depending on the contract and severity of the defects.
Any concession should be documented.
Shipping goods that failed inspection without written agreement can turn a manageable factory issue into a commercial dispute after delivery.
Who pays for a pre-shipment inspection?
There is no universal rule for commercial PSI.
The sales contract or purchase order should state who pays.
Depending on the arrangement:
- the buyer may appoint and pay the inspection company
- the exporter may pay because inspection is part of the agreed supply obligation
- the parties may agree on one allocation for the first inspection and another for re-inspections
- a government-mandated inspection programme may have its own fee rules
Where a letter of credit requires an inspection certificate, the exporter should also check exactly who is authorised to issue it and what the certificate must state.
A perfectly good inspection report can still create a documentary problem if it does not comply with the credit's terms.
Is a pre-shipment inspection certificate required for a letter of credit?
Only if the letter of credit requires one.
Letters of credit specify the documents that must be presented for payment. An inspection certificate can be one of those documents where the parties have included it in the credit.
If it is required, exporters should check before shipment:
- required document title
- who must issue or sign it
- wording or data required
- number of originals or copies
- whether a particular inspection company is named
- presentation deadline
The inspection should be planned around those documentary conditions.
Discovering after shipment that the certificate was issued by the wrong party or contains the wrong description can create an LC discrepancy even if the goods themselves are satisfactory.
What is the difference between pre-shipment inspection and quality control?
Quality control is the broader process of checking and managing product quality throughout production. Pre-shipment inspection is one quality-control checkpoint performed near the end of the production cycle before dispatch.
A robust exporter may use several controls:
Raw-material inspection → During-production inspection → Final/pre-shipment inspection → Container loading check
PSI is therefore a final safety net, not a substitute for controlling quality earlier in production.
If 40% of an order has already been manufactured incorrectly, discovering the problem earlier is far cheaper than waiting for final inspection.
What is the difference between pre-shipment inspection and container loading inspection?
A pre-shipment inspection focuses mainly on whether the goods meet the agreed requirements before they are released.
A container loading inspection focuses on what is actually loaded for shipment and how it is loaded.
A loading check may verify:
- container condition
- container number
- seal number
- quantity loaded
- carton count
- loading sequence
- packaging condition
- handling
- final container sealing
For higher-risk shipments, a buyer may require both.
The PSI confirms the approved goods. The loading inspection helps confirm that those are the goods that entered the container.
How can exporters prepare for a pre-shipment inspection?
Good preparation starts before the inspector arrives.
Freeze the quality requirements early
Define specifications, tolerances, defect categories, packaging, labels, and sampling requirements with the buyer before production.
Complete enough production
Do not book an inspection when a large portion of the order is unfinished unless that is specifically agreed.
Keep the goods accessible
Inspectors need to select samples across the shipment.
If cartons are inaccessible or already sealed into a container, representative sampling becomes harder.
Prepare reference documents
Keep the purchase order, approved sample, technical specifications, packing list, and inspection instructions available.
Carry out your own internal check first
The exporter or factory should inspect the order before the independent inspector arrives.
Paying for a third-party inspection to discover obvious problems that the supplier already could have found wastes time and can force a re-inspection.
Leave time for corrective action
Build inspection and possible rework into the shipment schedule.
The best inspection is useless if the business has committed to dispatching the goods regardless of what the report says.
Pre-shipment inspection checklist for exporters
Before releasing an international shipment, confirm:
- Purchase order and product specifications match the finished goods
- Required production quantity is complete
- Carton and unit counts are correct
- Agreed sampling and AQL criteria have been applied where relevant
- Critical, major, and minor defects are within the agreed acceptance limits
- Dimensions, weight, colour, and material match specifications
- Required functionality tests have passed
- Product-specific safety requirements have been checked
- Labels, warnings, barcodes, and shipping marks are correct
- Packaging is suitable for the shipment and product
- Required test reports or conformity documents are available
- Commercial and packing details align with the physical shipment
- Inspection findings have been reviewed
- Corrective actions and re-inspection are complete where required
- The approved goods are the goods being released for shipment
Why pre-shipment inspection matters for Indian exporters
For an Indian exporter, a failed shipment can cost much more than the value of the defective units.
It can create:
- replacement production
- international return freight
- demurrage or storage costs
- missed selling seasons
- customs complications
- invoice disputes
- delayed payment
- deductions or claims from the buyer
- loss of repeat business
A ₹20,000 rework at the factory may be frustrating.
The same problem discovered after a container reaches Rotterdam, London, or New York can become a substantially larger commercial issue.
That is why PSI should be viewed as risk control before the point at which fixing the problem becomes expensive.
How do inspection and payment terms connect?
Pre-shipment inspection can also affect when an exporter gets paid.
A sales contract might state that:
- the buyer pays only after the goods pass inspection
- a balance payment becomes due before shipment after a successful PSI
- an inspection certificate must be presented under a letter of credit
- the buyer can withhold release until specified defects are corrected
That makes the inspection report part of the commercial payment workflow, not just the quality workflow.
An exporter should know before production starts:
What inspection is required? Who approves it? What document proves approval? Does payment depend on that approval?
Once the goods are cleared for shipment and the buyer pays, the next operational challenge is being able to match that overseas payment cleanly with the relevant invoice and export records.
PayGlocal helps Indian exporters collect international payments and maintain clearer transaction and settlement records, making the payment side of cross-border trade easier to track after the quality and shipping checks are complete.
