Pre-Dispatch Inspection: Procedure and Steps to Build an In-House Program

A defective shipment that clears the factory undetected is one of the most expensive mistakes in sourcing. By the time it reaches your warehouse, or worse, your customer, you’re not just dealing with the cost of the goods. You’re looking at return logistics, rework, customer complaints, and in some cases, a relationship with a retailer or distributor that took years to build.

Most brands respond to this problem in one of two ways: they skip pre-dispatch inspections entirely and accept the risk, or they outsource every check to a third-party inspection firm and absorb the cost indefinitely. Neither approach is optimal. The first is a gamble. The second creates dependency, limits your product knowledge, and rarely pays off once your inspection volume grows.

Building your own in-house pre-dispatch inspection program is the professional middle ground. This guide gives you that procedure. By the end, you’ll have a working blueprint covering setup, execution steps, report format, and the container loading check: everything you need to run a consistent pre-shipment inspection with your own team.

What is a Pre-Dispatch Inspection?

A pre-dispatch inspection is a formal quality check conducted at a supplier’s facility once production is 80–100% complete, before goods are packaged for shipment. The inspector verifies quantity, product quality, spec conformity, packaging, labeling, and safety, documenting every finding in a written report.

The terminology can be confusing. Pre-dispatch inspection, preshipment inspection, PSI, and final random inspection all refer to the same process. “Pre-dispatch” is the term used most commonly in the UK markets; “pre-shipment” is standard in US and international trade contexts. Both mean the same thing: a structured quality check before goods leave the factory.

PSI is mandatory in some situations; letters of credit often require independent inspection certificates, and certain regulated product categories (electronics, toys, textiles) may require conformity documentation before customs clearance.

In-House vs. Third-Party Pre-Dispatch Inspection: How to Choose

The right model depends on how often you inspect, how well your team knows the product, where your suppliers are located, and whether impartiality is a requirement.

Factor	In-House	Third-Party
Cost at high inspection volume	✅ Lower per inspection	❌ $149–$320/man-day (QIMA from $309 in Zone A)
Product familiarity	✅ Deep, consistent knowledge	⚠️ Varies by firm and inspector
Objectivity/impartiality	⚠️ Risk of internal bias	✅ Independent, credible to buyers
Deployment speed	✅ On your schedule	⚠️ 24–48 hour booking lead time
Geographic reach/new markets	❌ Requires travel or local hire	✅ Global network, immediate access
New supplier or high-risk order	⚠️ Less credible without a track record	✅ Recommended
Letter of credit requirement	❌ Not accepted	✅ Required

A hybrid model works well for most growing brands: in-house teams handle routine inspections with established suppliers, while third-party inspectors cover new supplier relationships, high-stakes orders, or situations where an independent result is contractually required.

Types of Pre-Shipment Inspections

There are four main types of pre-shipment inspections, each covering a different stage of the production cycle. Pre-shipment inspection and quality control span the full production timeline through these check types:

1. Pre-production inspection: Verifies raw materials, components, and initial samples before manufacturing starts.
2. During-production inspection (DUPRO): Checks quality midway through production, when 20–50% of goods are complete. Catches issues while there’s still time to correct them at scale.
3. Pre-shipment inspection (PSI): The primary final check at 80–100% production completion. This is what this guide covers in full.
4. Container loading inspection (CLI): A separate check that supervises the physical loading process after PSI.

How to Set Up Your In-House Pre-Dispatch Inspection Procedure

Setting up a reliable pre-dispatch inspection procedure requires you to define the scope, assign ownership, standardize your tools, and align your suppliers before the first inspector sets foot in a factory.

Define Scope and Inspection Triggers

Start by defining which shipments require a PSI. Not every order needs a full inspection, but every team needs a clear rule for when one is mandatory.

Common trigger criteria include:

• New supplier: Inspect every shipment for the first 3–5 orders, regardless of order value.
• Order value threshold: Any order above a set value (e.g., $10,000) triggers a mandatory PSI.
• Product risk level: High-risk categories (electronics, children’s products, regulated goods) always require inspection.
• Supplier performance history: Suppliers with a previous defect rate above your AQL threshold stay on mandatory inspection until they achieve three consecutive passes.
• Routine established suppliers: Inspect every third to fifth shipment as a baseline once a supplier has a clean track record.

The goal is a simple decision tree your QA team can follow without judgment calls. Documenting this in your quality manual makes it auditable and consistent across team members.

Assign Roles and Responsibilities

Assign three roles explicitly in your PSI program:

• Inspection owner: The person who schedules the inspection, briefs the inspector, and reviews the final report. Usually, a QA manager or sourcing manager.
• Inspector: The person who conducts the on-site check. Can be a dedicated QC inspector, a local QA representative, or a sourcing office employee trained in your procedure.
• Approval authority: The person who makes the accept/reject call and communicates the decision to the supplier. Should not be the same person who manages the supplier relationship; this is the internal objectivity problem.

Build Your Product-Specific Checklists

Every PSI checklist must cover the core areas: quantity, visual appearance and workmanship, product spec conformity, labeling and packaging, and function tests. Beyond that, the checklist should be specific to your product.

The starting point for every new product checklist is the purchase order (PO) and the product spec sheet. Every checklist item should trace back to a written requirement that both you and the supplier have agreed to.

A practical build sequence:

1. Pull the PO and approved sample details.
2. List every measurable spec: dimensions, weight, color codes, materials, and regulatory markings.
3. Add workmanship criteria: acceptable vs unacceptable surface finish, joint quality, and print registration.
4. Add packaging requirements: carton dimensions, inner pack quantities, labeling content, barcode format.
5. Add function tests: what to operate, what to measure, what pass/fail looks like.
6. Map each item to a defect category: critical, major, or minor.

Paper checklists get lost, filled in inconsistently, and produce results that are nearly impossible to analyze over time. Digital checklists solve all three problems. GoAudits’ drag-and-drop builder lets QA teams create product-specific PSI checklists in minutes, with 800+ ready templates as a starting point.

Set Your AQL Sampling Standard

Acceptable Quality Limit (AQL) is the maximum percentage of defective units considered acceptable in a product batch before the shipment is rejected. It’s the statistical basis for deciding how many units to inspect and what defect rate triggers a fail.

The industry standard for general consumer products, per ISO 2859-1 / ANSI Z1.4, is:

• AQL 0 for critical defects (safety hazards, regulatory violations, anything that could harm the end user)
• AQL 2.5 for major defects (defects likely to cause customer rejection or returns)
• AQL 4.0 for minor defects (small cosmetic issues unlikely to cause returns)

In practice, the relationship between pre-shipment inspection and quality control standards like AQL works like this: for a batch of 3,201–10,000 units at normal inspection level II, your inspector examines 200 units. At AQL 2.5, the batch fails if more than 14 major defects are found.

Why setting AQL levels before the inspection matters: If AQL levels aren’t agreed in writing before the order is placed, any rejection becomes a commercial dispute. Suppliers will argue that the defect rate is acceptable. Buyers will argue it isn’t. The only way to avoid this conversation is a signed quality agreement that specifies AQL levels, defect classifications, and the consequences of a failed PSI.

Prepare Your Supplier Before the Inspection

Poor supplier preparation is one of the most common reasons a PSI fails or has to be rescheduled. It’s entirely preventable.

At minimum, communicate the following to your supplier at least 48–72 hours before inspection day:

• Inspection date and start time
• The production completion threshold required (80–100% packed and ready)
• Which product lines and order references will be checked
• What documentation they need to have available: packing list, purchase order, product spec, test certificates, compliance documentation
• Who on their side will be the inspection contact

A common objection from QA teams is that giving the supplier the checklist in advance is “cheating.” It isn’t. Sharing the checklist before the inspection sets a clear, mutual quality standard. It tells the supplier exactly what will be examined and reduces the number of surprises on inspection day. If a supplier uses that information to correct genuine defects before the inspector arrives, that’s the system working as intended.

What you can’t allow is selective presentation: suppliers showing only their best-performing units from the front of the production run. Random access to the full batch must be stated in your quality agreement.

This is where supply chain compliance software pays for itself: you can share checklists digitally with suppliers in advance, set inspection schedules, and maintain a documented record of every communication. That removes the ambiguity that causes disputes later.

How to Execute the Pre-Dispatch Inspection: Essential Steps

The pre-shipment inspection procedure below covers the core steps your inspector follows on-site. Each step is part of a structured pre-shipment product inspection that maps directly to a section of the report. Each step maps to a section of the inspection report.

1. Opening check: Confirm production status with the supplier before opening a single carton. Verify that at least 80% of the batch is complete and packed. Review the PO, approved sample, and product spec sheet together with the supplier contact. If the batch isn’t at the required completion threshold, the inspection shouldn’t proceed. Rescheduling costs less than a flawed result.
2. Quantity verification: Count the total number of cartons against the packing list. Open a sample of cartons and verify the inner pack quantity. Record any discrepancy between the ordered quantity, the packed quantity, and the found quantity.
3. AQL random sampling: Select samples from across the entire batch. Use your pre-agreed AQL level and lot size to determine sample size. Record the selection method and unit identifiers. A sample that isn’t truly random invalidates the whole inspection.
4. Visual and workmanship inspection: Examine each sampled unit for defects. Classify every finding as critical, major, or minor. Photograph every defect: close-up, in context, with a reference object for scale where relevant. Use a visual inspection checklist to standardize defect identification and photo documentation.
5. Product spec conformity: Measure dimensions against the spec sheet. Verify materials, colors, and finishes against the approved sample. Check that regulatory markings (CE, RoHS, UL, country of origin) are present and correctly formatted for the destination market.
6. Function and safety testing: Run relevant tests: electrical function, mechanical movement, chemical composition checks (where applicable). Confirm compliance markings are valid and that the product meets the destination market’s regulatory requirements.
7. Packaging and labeling check: Inspect packaging for structural integrity: no crushing, moisture damage, or unsealed flaps. Verify all labeling content against the PO requirements: product name, model number, country of origin, safety warnings, and barcodes. Scan barcodes to confirm they read correctly.
8. Documentation review: Cross-check the commercial invoice, packing list, certificates of conformity, and any required regulatory documents against the purchase order.
9. On-site findings discussion: Before leaving the facility, brief the supplier on your findings. If minor issues can be corrected before shipment, agree on the fix and set a re-check timeline. For major findings, confirm that nothing ships until written corrective actions are agreed upon.
10. Inspection report generation: Compile all findings, photos, measurements, and test results into the formal pre-dispatch inspection report. With a digital inspection reporting tool, this is generated automatically at the end of the checklist. No manual write-up required.

The operators are now able to take pictures of non-conformances, so the QA team sees the non-conformance as the operator does. This has helped with clarity and improved communication.

What Should a Pre-Dispatch Inspection Report Include?

A pre-dispatch inspection report is the formal record of every finding from the PSI. It serves three purposes at once: the accept/reject decision document, the corrective action brief for the supplier, and the long-term performance record for supplier scoring.

Here’s what a pre-shipment inspection report should contain:

• Header: Order number, supplier name and address, inspector name, inspection date and location, product description, and model reference
• Quantity summary: Ordered quantity vs. packed quantity vs. inspected quantity, with any discrepancies flagged
• AQL sampling summary: Lot size, inspection level, sample size, AQL levels applied, number of defects found by category (critical/major/minor), accept or reject result
• Defect log: Each defect is listed individually, with photo evidence, defect type, defect code, and quantity of affected units
• Workmanship and spec results: Pass/fail per checklist section, with supporting photos and measurements
• Packaging and labeling results: Pass/fail per packaging requirement, photos of any issues
• Function test results: Pass/fail per test conducted, with notes on methodology
• Overall result: Pass / Fail / Pending (a conditional pass where minor issues require supplier confirmation before shipment is released)
• Corrective action requirements: Specific actions required, responsible party, deadline, and re-inspection requirement if applicable
• Inspector sign-off: Name, date, and signature

How to Run a Container Loading Inspection

A container loading inspection (CLI) is a separate final check conducted after PSI, at the point when goods are physically loaded into the shipping container. It confirms that the right goods are loaded correctly, the container itself is fit for transit, and the seal is intact before the unit leaves the facility.

What to check on the container itself before loading begins:

• Structural condition: dents, rust, holes, or cracks that compromise integrity
• Light leaks: close the doors and check for any light coming through the walls or roof
• Door seals and locking bars: intact and functioning
• Interior moisture: no standing water, no visible damp, clean and dry floor
• Odor or contamination: no chemical smell, no evidence of previous hazardous cargo, no pest activity
• CSC plate: valid and in date (the container’s safety certification)

The 6 container loading inspection steps:

1. Pre-loading spot check: Before loading starts, pull a sample of cartons from the batch and confirm condition and quantity match the PSI results.
2. Carton inspection: Check that cartons are dry, undamaged, and properly sealed. Verify fumigation stamps on wooden pallets where required by the destination country (ISPM 15).
3. Loading plan verification: Confirm the loading plan is being followed: correct stacking pattern, weight distribution, fragile items on top, and no overloading.
4. Supervision of the loading process: Stay on-site throughout loading. Monitor handling: no dropping, no dragging, no improper stacking. Verify the loading method matches the requirements for the product type.
5. Final quantity check: Once loading is complete, confirm the total carton count against the packing list. Any discrepancy needs to be resolved before the container is sealed.
6. Seal and document: Fit a tamper-evident seal, record the seal number in the inspection report, and photograph the sealed container doors. The seal number should be confirmed on the bill of lading.

Common Mistakes In-House PSI Teams Make (and How to Avoid Them)

These are the mistakes in-house teams make most often:

• Inspecting too late: Waiting until 100% of the batch is packed leaves no time for rework before the ship date. Schedule your PSI when 80% of production is complete and packed. That window exists precisely so corrections can be made without delaying shipment.
• Using a generic checklist: A checklist not tied to the specific product’s PO and spec sheet will catch the wrong things and miss the right ones. Every product category needs its own checklist built from its own requirements. GoAudits makes it straightforward to build and version product-specific checklists without starting from scratch each time.
• Front-of-pile sampling: Selecting samples only from the cartons nearest the warehouse door is the single most common way suppliers game a PSI. Inspectors must pull samples from across the full batch: different rows, different stacking positions, and different production dates where visible.
• No photo documentation: A finding without a photo is a finding that can be disputed. Suppliers will claim the defect isn’t representative, or that the inspector’s description is ambiguous. Photos attached directly to checklist items remove that ambiguity entirely.
• Verbal corrective actions: Telling a supplier to fix something on-site, without a written record, leaves no accountability trail. Every corrective action must be documented in the inspection report, with a deadline and a re-inspection requirement.
• Conflating PSI with container loading: A passed PSI does not mean the job is done. The loading inspection is a separate step with its own criteria. Treating them as the same check is how undamaged goods leave the factory and arrive at port broken.
• No trend tracking: Running manufacturing inspections without recording results over time means you can’t identify which suppliers are deteriorating, which product categories have recurring defects, or whether your AQL levels need adjusting. Use corrective action software to close the loop on findings and build a usable performance record over time.

What Happens When a Pre-Dispatch Inspection Fails?

A failed pre-dispatch inspection does not automatically mean the shipment is rejected. The right response depends on the type and severity of the defects found.

Decision framework by defect type:

• Critical defects found: Stop the shipment. No exceptions. Critical defects are safety hazards or regulatory violations. Releasing the goods creates liability, not just a quality problem. Require full rework or replacement and a re-inspection before any shipment proceeds.
• Major defects above AQL threshold: Do not release the shipment. Negotiate with the supplier: full rework, partial shipment of conforming units only, or re-inspection after correction. Agree in writing before any goods move.
• Minor defects above AQL threshold: Document the findings and issue a formal corrective action request with a deadline. In some cases, a conditional release is appropriate if the defect level is marginally above threshold and the product function is unaffected, but this should be a deliberate decision, not a default.

How to communicate a failed inspection to your supplier:

Send the full inspection and QC report with photo evidence. Include a written corrective action request that specifies exactly what needs to be fixed, by when, and what re-inspection requirement applies before the shipment is released. Keep the tone factual. The report does the talking.

Use an inspection software like GoAudits to conduct the inspection, complete corrective actions, and generate a comprehensive report that can be shared instantly with the supplier.
