A factory visit is the only way to confirm a supplier is real — but only if you know what to look for. Based on 1,243 supplier investigations, 43% of fraud cases involved false production capacity claims, and 28% had fake export experience. In most of these cases, a proper on-site verification would have caught the deception before any money changed hands. This guide covers exactly what to check, photograph, and document during a Chinese factory visit.
Quick Guide: 10-Minute Factory Checklist
- Verify address — Does the physical location match GSXT registration?
- Count machines — Does equipment match what was claimed?
- Count workers — Enough staff for claimed production volume?
- Check inventory — Raw materials and finished goods present?
- Inspect quality control — Is there a QC process on site?
- Talk to workers — Voluntary interviews reveal real conditions
- Check certifications — Are ISO, CE, or CCC certificates genuine?
- Photograph everything — GPS-tagged photos are your best evidence
Step 1: Desktop Preparation Before the Visit
A factory visit without preparation is a sightseeing trip, not an investigation. Before arriving, run these checks:
- GSXT registration check — Confirm the company exists, the legal representative is real, and the registered address is not a virtual office
- Litigation and enforcement check — Search Wenshu (court judgments) and ZXGK (enforcement) for legal problems
- Claimed capacity vs. industry benchmarks — A supplier claiming 15 production lines should have the facility size and workforce to support it
- Export records — If they claim export experience, ask for customs declarations or shipping documents in advance
- Prepare a checklist — Write down exactly what you need to verify during the visit so nothing is missed
Our data shows that 40% of red flags can be identified before ever setting foot in the factory. The desktop check saves time and focuses the on-site visit on the highest-risk areas.
Step 2: What to Check During the Factory Visit
Arrive without warning if possible, or arrive early. A scheduled visit allows time for staging. An unscheduled visit reveals reality.
Production Floor
Walk the entire production floor. Count every machine. Note machine models, ages, and whether they are running. A factory with 50 machines but only 5 running may have financial problems. A factory with machines that are clean but have no dust or oil may have brought them in for your visit.
Workforce
Count visible workers. Note their activity levels. Ask the production manager how many workers per shift. A factory claiming 200 workers but showing 20 on the floor is either exaggerating or operating at a fraction of claimed capacity.
Inventory
Check raw material stock. A factory without raw materials cannot produce anything. Check finished goods — do they match the products the supplier claims to manufacture? Check production waste — real production creates waste; a spotless factory floor may be staged.
Quality Control
Look for a dedicated QC area with testing equipment. Ask to see QC records. Check if there are any quality certifications displayed and verify their validity. A factory without QC processes will not produce consistent quality.
Office and Management
Check the office area. Are there staff working on computers? Are there order files, shipping documents, and supplier correspondence visible? A factory without an administrative office may be a shell operation.
Step 3: How to Verify Production Capacity
False production capacity is the most common supplier deception, appearing in 43% of our fraud cases. Here is how to verify whether a factory can actually deliver what it promises:
| Claim vs. Reality Check | What to Verify | Fraud Indicator |
|---|---|---|
| Claimed vs. actual machines | Count machines, check model numbers | Fewer machines than claimed, rented equipment |
| Claimed vs. actual workers | Count on floor, check shifts | Worker count does not match claimed capacity |
| Claimed vs. actual output | Ask for recent production records | Cannot provide records, numbers are inconsistent |
| Claimed vs. actual export volume | Request customs declarations | No export records despite claimed experience |
| Claimed vs. actual clients | Ask for reference contacts | References are unreachable or suspicious |
Simple Capacity Math
For manufacturing factories, use this formula: (Number of machines) x (Hours per day) x (Efficiency rate) = Realistic daily output. Compare this against the supplier's claimed monthly capacity. If the numbers do not align, the claim is likely false.
Step 4: What to Photograph and Document
Photos are the most powerful evidence from a factory visit. Take photos of:
Exterior & Location
- ☐ Factory building from street
- ☐ Street name and number
- ☐ Factory sign / nameplate
- ☐ Neighboring buildings
- ☐ Parking lot (worker vehicles)
Production Floor
- ☐ Each machine with model number
- ☐ Workers at their stations
- ☐ Production line overview
- ☐ Raw material inventory
- ☐ Finished goods stock
Quality & Safety
- ☐ QC testing area
- ☐ Certifications on wall
- ☐ Safety equipment
- ☐ Fire extinguishers
- ☐ Exit signs
Office & Documentation
- ☐ Office area overview
- ☐ Business license on wall
- ☐ Order files on desks
- ☐ Shipping records
- ☐ Staff at computers
Top 5 Factory Visit Red Flags
- Empty or idle factory — No production activity, no inventory, no workers. The most obvious sign of a shell operation.
- Brand-new equipment still wrapped — Machines brought in for show but never used. The supplier may have rented them for your visit.
- Workers who cannot answer basic questions — Temporary workers hired to create the appearance of an active factory. Ask specific questions about what they are producing.
- Address mismatch — The factory is at a different location than the registered address on GSXT. Present in 76% of fraud cases.
- No quality control visible — No QC staff, no testing equipment, no inspection records. Without QC, consistent product quality is impossible.

Frequently Asked Questions
Should I announce my factory visit in advance?
Announced visits allow suppliers to prepare, which may mean seeing a staged version. Unannounced visits reveal reality. If you must announce, arrive several hours early to observe the facility before the official tour begins.
Can I do a virtual factory tour instead of visiting?
Video tours are better than nothing but can be staged. Fraudsters have been documented using someone else's factory for video calls. An in-person visit is the only reliable verification method for orders over $50,000.
What if the supplier refuses a factory visit?
Refusal to allow a factory visit is itself a red flag. Legitimate manufacturers welcome buyer visits. If the supplier makes excuses, consider it a warning sign and proceed with extreme caution.
How much does a professional factory verification cost?
A comprehensive factory verification including desktop research, on-site inspection, worker interviews, photo documentation, and a written report: $1,500-$4,000 depending on factory location and scope.
How long does a factory visit take?
A proper on-site inspection takes 2-4 hours for a small to medium factory, or a full day for large facilities. Combined with travel time, desktop preparation, and reporting, allocate 3-5 business days total.
