A factory audit is one of the highest-ROI activities a buyer can undertake before placing a significant production order. A half-day audit can surface problems that would otherwise cost you an entire production run. The economics are stark: a $400 audit — or even a careful live video walkthrough — is a rounding error against a five-figure order that arrives unsellable, stuck in customs, or from a "factory" that turns out never to have existed. A first step is confirming the supplier is real — see how to verify a China supplier's business license.
This checklist covers four audit domains: legal and commercial verification, production capability, quality management systems, and social/environmental compliance. Sourcing one category? Our China furniture supplier audit checklist applies the same method to furniture-specific risks.
When to Audit — and How Often
Audit before your first significant order with any new supplier; that is the single highest-return moment in the whole sourcing process. After that, re-audit when you scale volume sharply, when quality drifts on incoming shipments, when a factory changes address or ownership, or roughly every 12–24 months for an ongoing relationship. A cheap sample and a smooth first order are not evidence that a factory can hold quality across a full container-load — the audit is what tells you whether the capacity behind the quote is actually there.
What a Factory Audit Actually Covers
A China factory audit is a structured on-site — or verified-remote — inspection that confirms a supplier is a genuine manufacturer and can make your product to spec, legally and repeatably. In practice buyers run one of four audit types, and knowing which you need keeps the visit focused:
| Audit type | What it checks | Common standard |
|---|---|---|
| Quality / technical | Production capability, QMS, equipment, records | ISO 9001 |
| Social compliance (HR / ethical) | Labour contracts, hours, wages, health & safety | SMETA, BSCI |
| Environmental | Permits, emissions, waste handling | ISO 14001 |
| Security | Supply-chain and cargo security | C-TPAT |
The 27 points below combine the two an importer needs most — a quality/technical audit and a social-compliance (HR) audit — into one walkthrough. If a retailer mandates a formal ethical audit, insist on a full SMETA or BSCI report rather than a certificate screenshot, and check whether it was announced or semi-announced.
Domain 1: Legal & Commercial Verification
- Business license on display — Valid, current, matching the factory name on your contract
- Unified Social Credit Code — 18 characters, verifiable at gsxt.gov.cn
- Business scope includes manufacturing — Not limited to "trading" or "consulting"
- Export license — Required for most product categories; confirm they have it
- Bank account in company name — Payments to personal accounts are a major red flag
- Legal representative identity — Person signing contracts should match registration
- Company age — New registrations (under 2 years) warrant extra scrutiny
Two of these points do most of the filtering. Pull the 18-character Unified Social Credit Code and check it yourself on the national enterprise credit system at gsxt.gov.cn: a real manufacturer's registered business scope contains wording like "production" or "manufacturing", whereas a pure trading company reads "sales", "wholesale" and "import/export" only. And insist your deposit is wired to a corporate account whose name matches that licence exactly — a request to pay a personal account is one of the most reliable fraud signals there is.
Domain 2: Production Capability
- Facility size matches claimed capacity — Walk the floor; does the space match their stated output?
- Equipment ownership vs. rental — Do they own their key machinery or subcontract?
- Workforce headcount — Count production workers on the floor, not just the claimed number
- Subcontracting disclosure — What percentage of production, if any, is outsourced?
- Sample production capability — Can they run small sample batches in-house?
- Raw material inventory — On-site stock of key materials indicates genuine operations
- Machinery maintenance records — Regular maintenance logs suggest operational discipline
Production-capability evidence matters most when one order spans many categories at once. A hotel FF&E project, for example, relies on each specialist factory genuinely making its own category in-house, so verify capacity category by category rather than trusting a single headline output figure. The same discipline applies when you are buying a machine rather than a finished good — vetting a press maker on equipment ownership, in-house build and maintenance records is exactly the groundwork our guide to buying a UV flatbed printer from China recommends before any deposit changes hands.
Domain 3: Quality Management Systems
- Incoming material inspection — How do they verify raw material quality on receipt?
- In-process quality checks — What checkpoints exist during production?
- Final inspection protocol — Is there a documented outgoing inspection process?
- Non-conformance handling — How are defects identified and resolved?
- Quality records retention — Can they provide inspection records from previous production runs?
- Calibration records — Measuring instruments should be calibrated and logged
- ISO 9001 certification — Valid certificate from an accredited certifying body
Certificates are the floor, not the ceiling. An ISO 9001 certificate proves a system exists on paper; ask to see it working — recent incoming-inspection logs, a non-conformance report with its corrective action attached, and in-date calibration stickers on the calipers and gauges. The strongest single piece of evidence is a signed golden sample kept on file that mass production is checked against. If the team can produce last month's inspection records without hesitation, the quality system is real rather than decorative.
Domain 4: Social & Environmental Compliance
- Worker contracts on file — Chinese labour law requires written employment contracts
- Working hours compliance — Maximum 8 hours/day, 40 hours/week standard; overtime rules apply
- Minimum wage compliance — Each GBA city has a published minimum wage; confirm adherence
- Safety equipment provision — PPE, fire extinguishers, emergency exits clearly marked
- Environmental permits — Required for factories with chemical, paint or finishing processes
- Waste disposal records — Proper waste handling documentation for applicable product types
Social compliance has become commercial, not just ethical. Major Western retailers and marketplaces increasingly require a valid SMETA or BSCI audit before they will onboard a supplier at all, and a failed ethical audit can freeze an entire buyer relationship. Treat this domain as a gating requirement if you sell into those channels: confirm the audit is current, check whether it was announced or semi-announced, and read the corrective-action section rather than just the cover grade.
Running the On-Site Visit
Come prepared to see, not just to be shown. Bring your spec sheet and a reference sample, a camera (confirm photos are allowed first), and this checklist printed or on your phone. Insist on seeing the production floor before the meeting room — a common tactic is to keep buyers in a polished showroom and away from a thin or idle line. On the floor, count the workers actually working against the headcount claimed, look for raw-material and work-in-progress inventory consistent with the stated output, and ask to watch one unit move through a real production step. Photograph the machinery nameplates and the posted business licence. Ask open questions and listen for specifics: a genuine operator answers with lead times, defect rates and material sources without hesitation, while a middleman deflects with "no problem, we can do everything". Finish by walking the incoming-goods and finished-goods stores — empty racks or mismatched finished products are a sign the "factory" is really consolidating other people's output.
Announced, Semi-Announced or Unannounced?
An audit the factory has known about for two weeks tells you how good they are at preparing for audits — not how they run day to day. Announced visits get you cooperation and document access; unannounced visits catch the real floor state but may hit a locked gate. The practical middle ground most audit firms recommend is semi-announced: you agree a window (say, "some day in the next two weeks") but not the exact date. You get access and honesty at once.
Scoring and What to Do With the Findings
An audit only pays off if the result drives a decision. Turn findings into a short corrective-action plan (CAPA / CAPR): each major issue gets an owner, a fix and a deadline, with photo evidence on closure. Re-check or request that evidence before releasing your deposit. Treat any critical finding as a hard stop until resolved — those are the issues that end in seized goods, blocked shipments or reputational damage, not just a few percent of defects.
Conducting the Audit Remotely
If you can't attend in person, you have two solid options. The first is hiring a third-party audit firm — Bureau Veritas, SGS, Intertek or a reputable local alternative. A standard factory audit costs $300–600 for a man-day and produces a detailed written report with photos; for your first significant order with a new supplier, it is essential spend.
The second is a structured live video audit you run yourself. Don't accept a pre-recorded tour. On a live call, ask the supplier to walk the full production floor in one continuous shot (not edited clips); screen-share their ERP or MES and open a live work order for a current job; show the incoming-materials store and the QC bench with real inspection records; and pan to the fire exits and the posted business licence. A factory that genuinely produces can do all of this on request — a trading company will steer you to a showroom and struggle to pull up a live work order.

Factory Audit vs Supplier Verification vs Pre-Shipment Inspection
These three are often confused but happen at different stages. Supplier verification is the desk check that a company legally exists and is a manufacturer — see business-licence verification. A factory audit (this checklist) is the deeper on-site assessment of capability, quality systems and compliance before you commit. A pre-shipment inspection checks the actual finished goods against your spec and AQL before you pay the balance — covered in our pre-shipment inspection guide. Serious buyers do all three: verify first, audit before the first big order, and inspect every shipment.
Frequently Asked Questions
What is a factory audit in China?
A structured on-site or verified-remote inspection that confirms a supplier is a genuine manufacturer and can produce your product to spec, legally and consistently — covering legal and commercial status, production capability, quality systems and social / environmental compliance.
How much does a China factory audit cost?
A third-party quality audit from firms like SGS, Bureau Veritas or Intertek typically runs $300–600 for a standard man-day, including a written report with photos. Social-compliance audits (SMETA, BSCI) cost more because they take longer.
What is the difference between an announced and unannounced audit?
Announced audits are scheduled in advance and guarantee access but let the factory prepare; unannounced audits show the real day-to-day state but risk being turned away. Semi-announced — a known window with an unknown exact day — is the common compromise.
What is a social compliance or HR audit?
An ethical audit of labour practices — employment contracts, working hours, wages, and health and safety — usually against the SMETA (Sedex) or BSCI frameworks. Many Western retailers require one before onboarding a supplier.
Can I audit a Chinese factory remotely?
Yes. Either commission a local third-party auditor or run a structured live video audit yourself — insisting on a continuous floor walk, a live ERP work order and real QC records rather than an edited showroom tour.
