Key Takeaways
- 1Online verification is a starting point — on-ground inspection catches what remote screening misses
- 2Always ask to see the production floor on the day of the visit, before any showroom tour
- 3The question 'have you had a shipment rejected at customs?' separates experienced exporters from beginners
- 4Never verify a supplier based on a single visit — always compare at least two factories before deciding
Online supplier verification — third-party audit reports, credit checks, trade references — all have a fundamental limitation: they tell you what a supplier says about themselves and what a third party observed at a point in time. They do not tell you what is happening on the production floor today, when your actual order would be running.
The only reliable supplier verification is on-ground inspection. This guide covers the complete framework used across 200+ factory visits.
The Verification Framework: Six Areas to Check
1. Manufacturing Licence and Business Scope
Before you step onto the production floor, verify the legal entity.
What to check:
- Business licence (营业执照) — confirms the company is a legitimate legal entity
- Manufacturing scope — the licence should list manufacturing activities, not just trading
- Export registration — companies that export regularly will have customs registration
- Registered capital — gives a sense of the company's scale and financial footing
How to verify: Ask to see these documents at the start of the meeting. Legitimate factories will have them available. If the person you are meeting cannot produce them or deflects, that is a signal.
2. Production Floor (The Core Verification)
Everything on the showroom floor is stage-managed. The production floor is where you see reality.
What to look for:
- Active production lines: how many are running today? Not in the brochure — today.
- Worker count on the floor: does it match the facility size they claimed?
- Machine types and age: do the machines match the product categories they claim to manufacture?
- QC checkpoints on the line: where in the production process does quality get checked?
- Raw material storage: are inputs stored cleanly and organized?
- Output staging area: what is waiting to be shipped?
Key questions while on the floor:
- "What is currently running on this line?"
- "How many workers are on shift today?"
- "When was this machine installed?"
- "Can you show me the QC records for last week's production?"
What to do
Ask to see the production schedule for the day. A factory that can show you what is planned versus what is running tells you about their operational management. A factory that cannot is either disorganized or is showing you a staged version of their operation.
3. Quality Control Systems
Quality control is not a final inspection — it should be embedded throughout production.
What to check:
- QC procedures at each production stage (not just at the end)
- Testing equipment on the floor (for your specific product category)
- Defect rate records and how they are measured
- Certification maintenance (ISO 9001, CE, etc.) — are current certificates displayed?
- Documented changeover procedures between product runs
Red flags:
- QC staff who appear during your visit but not during normal production
- Certificates on the wall but no visible QC activity on the floor
- Vague answers to "what is your defect rate?" — good factories track this precisely
- No separation between production and QC areas

For Australian businesses, export experience matters in two specific ways: operational experience with international logistics, and familiarity with the compliance requirements of developed markets.
What to check:
- Export history: which countries have they shipped to? Ask for specific examples of shipments to Australia, US, or EU
- Customs clearance experience: ask directly — "have you had a shipment rejected at customs, and what happened?" Experienced exporters will give a specific answer. Inexperienced ones will say "we have no problems"
- Documentation capability: can they produce Certificate of Origin, inspection certificates, and commercial invoices that meet Australian customs requirements?
- Communication during non-business hours: do they respond to technical questions outside Chinese business hours?
Key question: "Can you show me the documentation for your last three export shipments?" Any factory with consistent export experience will have this readily available.
5. Subcontracting and Supplier Network
Many factories — even legitimate ones — use subcontractors for specific processes. This is not inherently bad, but you need to know about it.
What to check:
- Ask directly: "Do you use any third-party factories for this product?"
- If yes, which processes are subcontracted?
- Can you visit the subcontractor's facility?
- How does the main factory quality-control subcontractor output?
Red flag: A factory that claims to be a one-stop manufacturing facility but cannot explain their full production chain in detail is either ignorant of their own supply chain or is a trading company presenting as a manufacturer.
6. Financial Stability and Communication
First orders are the most vulnerable. A factory that accepts a deposit and then changes terms, misses deadlines, or becomes unresponsive has already cost you more than any discount was worth.
What to check:
- Payment terms offered: for first orders, 30% deposit / 70% balance against copy of Bill of Lading is standard. Be cautious of 50%+ deposit requirements
- Responsiveness before the visit: did they answer technical questions promptly and specifically?
- Transparency about limitations: a factory that tells you "this MOQ is too low for that finish" is more trustworthy than one that says "yes, we can do everything"
- Business bank account: confirm the account is in the same company name as the manufacturing licence
What to do
For critical orders, conduct a third-party verification of the business licence through a Chinese credit agency. This confirms the company exists, has no outstanding legal judgments, and the registered capital matches what was claimed.
Red Flags: The Signals That Should Stop You
These signals, individually, may have explanations. Two or more together should cause you to pause before committing:
| Red Flag | What It May Signal |
|---|---|
| Refuses to show the production floor | Trading company or subcontracts everything |
| Fast agreement to every request | Over-promising; inability to deliver |
| No export experience to developed markets | unfamiliarity with quality expectations |
| Cannot show documentation for recent shipments | either new to exporting or misrepresenting volume |
| Salespeople who cannot introduce production manager | Disconnect between sales and operations |
| Pushes for large deposit before seeing facility | Potential scam risk |
| No physical address verification (only online profile) | May not be a real manufacturing operation |

Start your enquiryThe Verification Process: Step by Step
Step 1: Pre-Visit Screening (Before Travel)
- Run a business licence verification through a Chinese credit agency
- Check third-party audit reports (if available)
- Request a video call with the factory — observe their facility via video if they cannot do an in-person visit
- Collect trade references and check them directly
Step 2: On-Ground Visit
- Follow the six-area framework above
- Take systematic photos of: production floor, machines, QC checkpoints, warehouse, office
- Ask the production manager specific questions — not just the sales team
- Do not commit to any order on the day of the visit
Step 3: Post-Visit Assessment
- Compare what you saw against what was advertised
- Check references provided by the factory (call them)
- Request samples from the top two candidates
- Never rush the decision — a week of comparison is cheaper than a failed order

Frequently Asked Questions
What is a factory audit?
A factory audit is a structured inspection of a manufacturing facility to verify its capabilities, quality systems, and compliance. It can be conducted by your own team, a third-party inspection company, or a sourcing partner with on-ground presence. Audits cover production capacity, QC procedures, certifications, and financial stability.
How do I verify a Chinese supplier is a real manufacturer?
Ask to see the production floor on the day of the visit. Request the business licence and compare the registered manufacturing scope against what they claim to produce. Ask to meet the production manager (not just sales). A factory that cannot show you their own production floor in real time is not a manufacturer.
Is third-party verification reliable?
Third-party verification reports are useful as a first screen but have limitations: they represent a point-in-time snapshot, they may not cover your specific product category, and quality varies significantly between agencies. Use them as a starting point, not a final verdict.
How many factories should I visit before deciding?
Visit at least two factories for the same product category before making any purchasing decision. Comparing suppliers side-by-side gives you benchmarks that a single visit cannot provide.
