Key Takeaways
"Get it audited" isn't one instruction. A capability audit, a social compliance audit, and a pre-shipment inspection check three different things, and paying for the wrong one leaves the risk you actually cared about uncovered.
A pre-shipment inspection typically runs at 80 to 100% of production completion and checks a sample of finished goods against your specs and an AQL defect tolerance, not the factory's general capability or labour practices.
AQL 2.5 means a sample can contain up to 2.5% major defects and still pass. That's a real number worth understanding before you assume "passed inspection" means "zero defects."
Third-party inspection typically costs USD 200 to USD 350 per man-day, based on pricing corroborated across several inspection providers, which is small relative to the deposit or balance payment it's meant to protect.
Buyers hear "get it audited" as a single instruction. It isn't. A capability audit, a social compliance audit, and a pre-shipment inspection check are three completely different things, and most first-time buyers only discover which one they actually need after the wrong one has already passed.
That sounds like a technicality. But does a passed capability audit tell you the goods in your actual container are defect-free? It doesn't: capability audits check whether a factory can make your product, not whether a specific production run did. Does a clean social compliance report mean your production batch will match the sample you approved? It doesn't either: that's a different question again.
A supplier can pass one of these checks with flying colours and still ship you a batch that fails on arrival, because the two checks were never answering the same question.
This checklist breaks down what each type of audit and inspection actually verifies, what "passing" really means for each one, and which check should gate your next payment.
"Get It Audited" Means Three Different Things
Factory audits and inspections are split into several distinct categories that each check a different risk: capability, quality management, security/customs compliance, social compliance, environmental, and traceability audits, plus a separate category, pre-shipment inspection, that checks an actual production run rather than the factory as a whole. Most SME buyers only ever need two or three of these, but knowing which one answers which question changes what you should actually book.
Audit and Inspection Types at a Glance
| Check | What It Verifies | When You Need It |
|---|---|---|
| Capability Audit | Can this factory make your product, at your volume, on time | Before committing to a new supplier |
| Social Compliance Audit | Working conditions, labour practices, wages | Ethical sourcing commitments, customer due diligence requirements |
| Pre-Shipment Inspection | Does this specific production run match your spec and AQL tolerance | Before releasing final payment on an order |
Capability Audit: What It Checks (and What It Doesn't)
A capability audit verifies whether a supplier has the equipment, workforce, and production capacity to actually make your product to specification and deliver it on time and at volume. It's the check to run before committing to a new manufacturer or asking an existing one to scale up an order significantly.
What it doesn't do is tell you anything about a specific production run. A factory can have every machine and certification it claims and still ship a defective batch if something goes wrong on the floor that week. Treat a capability audit as a one-time or periodic check on the factory itself, not a substitute for checking the goods you're actually paying for.
If you're vetting a brand-new supplier for the first time, our China sourcing guide walks through the specific checks worth running before you commit to a factory at all, of which a capability audit is one piece.
Social Compliance Audit: What It Checks
A social compliance audit examines working conditions, labour practices, wages, and working hours, typically measured against SA8000 (an international standard for ethical workplace conditions). It exists to give you documented evidence of how a factory treats its workers, which matters if your business has ethical sourcing commitments or if your own customers are asking harder questions about your supply chain.
This audit tells you nothing about product quality or delivery timelines. A factory can run an ethical, well-documented operation and still produce goods that don't match your spec. It's a distinct risk category: run it for its own reason, not as a stand-in for a quality check.
Pre-Shipment Inspection: What Inspectors Actually Check
A pre-shipment inspection is the check most directly tied to the payment decision this article is really about. Unlike a capability or social compliance audit, it's order-specific: an inspector visits the factory once production reaches 80 to 100% completion and checks a statistical sample of the actual finished goods against your product specs, your agreed AQL defect tolerance, and your packaging requirements.
The inspector is looking at what's really in the boxes, not what the factory claims it can do in general. This is the check that catches the sample-switch problem, where an approved sample looked perfect but the bulk run doesn't match it, before the goods leave the country.
What AQL Actually Means for Your Order
AQL stands for Acceptable Quality Level (also called Acceptance Quality Limit), a specific application of ISO 2859-1, the international standard for statistical sampling in quality inspections. It sets a different tolerance for three defect tiers: critical defects (typically AQL 0, meaning zero tolerance), major defects (typically AQL 2.5), and minor defects (typically AQL 4.0).
AQL 2.5 means a sample can contain up to 2.5% major defects and the batch still passes. The exact number of defects allowed isn't a flat 2.5% of the units inspected, but comes from a standardised sampling table indexed to your lot size and sample size, and the resulting acceptance number is often higher than a simple percentage calculation would suggest.
This is worth knowing before you assume "passed inspection" means flawless. A passed inspection means the defect rate fell within a tolerance you (or your inspector, by default) agreed to, not that every unit is perfect.
Which Audit Should Gate Which Payment
Match the check to the payment it's meant to protect, not the other way around.
A capability audit belongs before you place a first order at all, since it's checking whether the supplier relationship makes sense in the first place, not any specific payment. A social compliance audit runs on its own schedule, tied to your company's own ethical sourcing commitments rather than a specific order's payment stages.
A pre-shipment inspection is the one that should gate your final balance payment. If your order follows the common deposit-then-balance structure, a passed pre-shipment inspection is the condition that should trigger releasing the remaining payment, not the supplier's say-so that production is complete.
What an Inspection Costs
Third-party inspection in China is typically priced per man-day, and pricing is corroborated across multiple inspection providers rather than sourced from a single official rate card. A man-day represents one inspector's full day at the factory: travel, physical sampling, and a written report. Rates commonly fall between USD 200 and USD 350 per man-day depending on product complexity, with basic consumer goods at the lower end and specialised or technical products at the higher end.
Set against a deposit or balance payment on even a modest order, that cost is small. The real cost of skipping it isn't the inspection fee: it's finding out about a defective batch after it's already on a container ship, a mistake our breakdown of sourcing scams first-time importers fall for covers from the other side of the same problem.
Paying Suppliers in Step With Your Inspection Results
The inspection only protects you if your payment structure actually depends on it. That means staging payment (a deposit on order confirmation, the balance only after a passed pre-shipment inspection) rather than paying in full upfront or on the supplier's own shipping timeline.
Statrys clients paying suppliers directly through a multi-currency business account use real-time SWIFT payment tracking (MT103) to confirm exactly when a staged payment clears, so both sides have a clear, timestamped record of when the balance moved relative to the inspection report clearing. That record matters if a dispute ever comes up later.
If you've been relying on a sourcing agent to handle this coordination, this is also the checkpoint where their fee is doing real work, and the point at which managing it directly starts to make sense once you're comfortable running these checks yourself.

FAQs
What is a factory audit checklist?
A factory audit checklist is a structured list of items an auditor or inspector verifies at a supplier's facility. What's on the checklist depends entirely on the audit type: a capability audit checks equipment and production capacity, a social compliance audit checks labour practices, and a pre-shipment inspection checks a specific production run against your spec and AQL tolerance.
What's the difference between a factory audit and a pre-shipment inspection?
A factory audit (capability, quality, or social compliance) evaluates the factory as a whole, its equipment, systems, or labour practices, independent of any specific order. A pre-shipment inspection evaluates the actual goods from a specific production run, checked against your spec once production is 80 to 100% complete. An audit checks the factory. An inspection checks the order.
What does AQL 2.5 mean in a quality inspection?
AQL 2.5 means a sample can contain up to 2.5% major defects and the batch is still considered acceptable under the ISO 2859-1 sampling standard. It's the most common tolerance level applied to major defects, sitting between AQL 0 for critical defects and AQL 4.0 for minor ones.
How much does a factory inspection cost in China?
Third-party inspection in China typically costs USD 200 to USD 350 per man-day, depending on product complexity, with basic consumer goods at the lower end and technical or specialised products at the higher end. A man-day covers one inspector's travel, sampling, and written report for a single day at the factory.
Should I pay the deposit before or after a factory audit?
A capability audit should happen before you commit to a new supplier at all, so it typically precedes any deposit. The deposit itself is standard practice once you've chosen a supplier. The balance payment is what should wait: hold it until a pre-shipment inspection of the actual production run has passed, not until the supplier says the goods are ready.
