How do I verify a Chinese supplier is a real factory?
Short Answer: Run Four Verifications, Not One
Verify the business licence on the national registry, request a live video tour of a working production floor, order a pre-production sample made on production tooling, and for orders above roughly $10,000 commission a third-party audit. A real factory welcomes all four; a trading company deflects them.
Why a Single Check Is Never Enough
There is no shortcut to confirming a Chinese supplier actually manufactures your product. The platforms where you find them have no real incentive to police factory-versus-trader claims, and the documents a supplier volunteers are exactly the documents they want you to see. So the question is not whether to verify but how many independent signals you are willing to gather before sending a deposit.
The four checks below each rule out a different deception. None of them is enough alone. Together they collapse most of the impersonation scenarios that catch out first-time importers.
The Four Checks That Actually Catch Impostors
We walk every new factory relationship through the same four steps at RND SOURCING, regardless of how polished the supplier's English website looks. The order matters: documentation first, visual second, sample third, audit fourth, because each step is more expensive than the one before it.
Pull the business licence and verify it on gsxt.gov.cn.
Get the 营业执照 image with the 18-digit Unified Social Credit Code. Look up the exact Chinese company name on the National Enterprise Credit Information Publicity System. Confirm the registered address, business scope covers your category, and status reads active.
Request a live WeChat video tour of the production floor.
Ask the salesperson to walk the shop floor with the camera on, showing machines running, workers in position, and a product resembling yours being made. Pre-recorded factory videos and stock photos are not substitutes for a real-time walk.
Order a pre-production sample made on production tooling.
A hand-finished mock-up proves nothing. Insist on a sample made from the same machines and moulds that will be used for the bulk run. The sample is also the moment your written specification gets stress-tested against what the line actually produces.
For orders above roughly $10,000, commission a third-party audit.
SGS, Bureau Veritas, Intertek or QIMA will send an auditor to the registered address and verify production capacity, workforce, machinery and quality system. Costs typically run $169-500 per man-day.
What a Real Factory Actually Lets You See
An authentic factory does not hide. They give you an address that maps to an industrial park. Their name is on the wall of the workshop. The same worker who picked up your video call last month is the one packing the order this month. Their tool room has duplicates of the machine that produced your sample. Their QC bench has a stack of inspection records in Chinese.

Case: The Factory That Was a Four-Desk Office
A buyer needed a small electronic accessory, found a polished Alibaba listing in Shenzhen, and asked us to do a routine third-party audit. The supplier's business licence had looked clean on the national registry. The trade assurance badge was paid up. The English sales engineer answered emails within hours.
The auditor arrived at the registered address at the appointed time and found a serviced office on the ninth floor of a commercial tower. Four desks, one printer, no goods. The supplier had sub-contracted the entire order to two different factories without telling the buyer, and was marking up both ends.
The Five Red Flags a Factory Check Should Catch
- Stock or stolen factory photos. A reverse image search on any factory photograph takes ten seconds. Re-used stock imagery is one of the highest-signal impostor tells.
- Catalogue that spans ten unrelated categories. A factory that makes power banks and yoga mats and stainless steel kitchenware is almost always a trading company. Real factories specialise.
- Owner or salesperson cannot answer a process question. Ask how a particular component is welded, sewn or assembled. The factory owner answers in a sentence. The middleman punts the question back to the factory later.
- Refusal to accept direct payment. Real factories will let you pay them and let the agent take a separate fee. A disguised trader insists everything goes through their own account.
- Address on an apartment building. Baidu Maps or Google Maps confirms in seconds. An industrial park is good. A residential tower is not.
Honest Limits of This Process
- A clean audit is a moment in time. Factories change hands, change tooling and change staff. Repeat the audit at meaningful order intervals, not just once.
- Audit quality varies. Choose an accredited firm and a defined audit scope. A walk-through inspection is not the same as a social-compliance audit.
- Video tours can be staged. Look for cumulative details: does the same machine appear across three calls? Are workers the same people? Is the clock on the wall moving?
- None of this replaces a written specification and inspection. Verification confirms who you are dealing with. A specification and inspection confirm what they are actually making for you.
How RND SOURCING Verifies Suppliers
We work from Yiwu, which is within driving distance of several thousand manufacturers in Zhejiang and the Yangtze River Delta. That makes the live video walk a low-cost default rather than an exceptional ask. We keep a list of factories we have personally visited within the past twelve months and we run a fresh video tour on every new supplier before any buyer deposit moves.
We are not an accredited testing laboratory and we do not issue audit certificates. We coordinate independent auditors when the order size justifies it. The verification chain ends at the third-party firm, not at us, and our role is to choose which factory to put in front of them.
If any factory refuses a video tour, an audit or a direct-payment option, that refusal is the most useful signal you will get.
