How to Verify Chinese Suppliers Before Sending Any Payment

Nearly every China sourcing horror story starts the same way: a deposit was wired to a supplier nobody properly checked. The good news is that most of these losses are preventable with a few hours of disciplined verification. This guide walks you through the exact checks to run before any money leaves your account, confirming the company is real, separating factories from middlemen, reading profile warning signs, and locking down samples and contract terms.

Start with the business license and export license

Every legitimate Chinese company has a business license issued by the State Administration for Market Regulation. Ask for a clear photo or scan and check three things: the registered company name, the business scope, and the registered capital. The English name a supplier uses in emails often differs from the real Chinese-registered entity, and that registered name is what you will eventually put on a contract and a bank transfer. If the name on the license does not match the company you have been talking to, stop and ask why.

Look closely at the business scope. A company registered only for 'trade' or 'import and export' is not manufacturing anything itself, no matter what the website claims. You can verify the license number against China's public company registries, where the registration date, status, and legal representative are all listed. A firm that has only existed for a few months handling a large order is a different risk profile than one with a decade of operating history.

Export rights are a separate matter. Not every factory holds its own export license, which means some perfectly real manufacturers ship through an agent. That is not necessarily a problem, but you need to know who actually issues your commercial invoice and customs documents, and whose bank account the money goes to. Surprises at this stage are expensive.

• Confirm the registered Chinese name matches the entity you'll pay
• Read the business scope, 'trade' means they don't manufacture
• Check registration date, status and capital on a public registry
• Ask who holds the export license and issues customs documents

Two details make that registry check far more reliable. The document you want is the business licence (营业执照), and the number that matters on it is the 18-character Unified Social Credit Code (统一社会信用代码). Search that code at gsxt.gov.cn, China national enterprise registry, and you get registered capital, registered address, business scope, year founded and legal representative straight from the source.

Then sanity-check the registered capital against what they claim to be. It is a rough number, but it is rough in a useful direction: a "factory" registered at 100,000 RMB, about 14,000 dollars, is not running a 40-machine OEM line. Real manufacturers in electronics, vehicles and industrial categories carry registered capital in the millions of RMB. A mismatch between the scale of the claim and the scale of the registration is one of the cheapest tells you will ever get.

Three checks you can run before you even message them

Everything above needs the supplier to send you something. These three do not. You can run all of them from the listing alone, in about ten minutes, before you have invested a single conversation.

Reverse image search the factory photos. Drop their "our factory" images into Google Images, TinEye and Yandex. Yandex is the strongest of the three at matching photos that have been cropped, mirrored or lightly edited. If those photos appear on another company website, they are not theirs, and there is nothing left to discuss.

Cross-check the registered address on Baidu Maps. Google Maps is close to useless inside China; Baidu Maps is not. Paste the registered address from the licence into map.baidu.com and look at the satellite view. An industrial structure is what you want to see. A residential block, a shopping mall or an empty plot means the production is happening somewhere else, almost always at a third party they are quietly subcontracting.

Check WeChat consistency. Real factory salespeople use a company WeChat ID, have years of history on the platform, and post production clips to their Moments feed. A blank profile created last month, attached to a company claiming fifteen years of exports, is telling you which of those two things is true.

• Reverse image search on Google, TinEye and Yandex, before anything else
• Registered address on Baidu Maps satellite view: industrial, or not
• WeChat account age and Moments history against the claimed company age
• Unified Social Credit Code checked at gsxt.gov.cn, not just the licence photo

Factory vs trading company: how to tell the difference

A large share of 'manufacturers' online are trading companies adding a margin between you and the real factory. Trading companies are not inherently bad, a good one can manage smaller orders, mixed product lines, and quality issues for you. The danger is paying factory-direct prices for trading-company service, or not knowing there is an extra link in the chain when something goes wrong.

The fastest test is a live video walk-through of the production floor. Ask them to film the specific line that makes your product, with workers and machinery running, and to pan to the building entrance and signage. A genuine factory can do this on short notice; a trading company will stall, send old footage, or only show a showroom. Pressing for technical detail works too, ask about machine models, cycle times, tolerances, and what they can and cannot adjust. People who actually run the line answer instantly; resellers go quiet and 'check with the factory'.

Cross-check the address as well. A registered manufacturing address in an industrial zone is a good sign; an office tower address in a city centre usually means trading. None of these signals are conclusive on their own, but together they paint a reliable picture.

• Request a live, unscripted video of your line running
• Ask technical questions only a factory could answer instantly
• Check whether the address is an industrial zone or a city office
• Decide consciously whether you want a factory or an agent, don't be surprised by it

A supplier who passes every check still gets your trust last, structure the payment so passing the inspection is the only way they get paid in full.

The one check that catches most fakes: the unannounced walkthrough

Document checks tell you whether a company exists on paper. The video call tells you whether the factory exists on the ground, and it is the single highest-yield thirty minutes in this entire process. The word doing the work here is unannounced. Book a 30-minute call on WhatsApp, WeChat or Teams, say you would like a quick walkthrough, and do not tell them in advance what you want to see.

Then, on the call, ask for these six things in this order:

• The main entrance sign with the company name on it. Real factories have a permanent sign at the gate. A trader borrowing another company factory usually skips straight past this.
• A continuous walk along the production floor, three to four minutes, not a still photo and not a cut. You want to see the line, the workers and the noise without an edit point.
• The production planning board. Most Chinese factories keep a whiteboard or printed sheet listing the orders for the week. It proves the line is not just real but currently working.
• One specific machine, started in front of you. Pick it yourself and ask the operator to run a 30-second cycle. This is the hardest item on the list to fake.
• The quality control room or station. Every genuine factory in your category has one.
• A phone on screen showing the date and time. This sounds paranoid right up until the first time you watch old footage being replayed as a live tour.

If they refuse, postpone, discover bad signal, or move the date even once, you already have your answer. Real factories show production, because showing it shortens the negotiation. Traders pretending to be factories show you a brochure.

A supplier who will not spend thirty minutes proving the factory is theirs is telling you exactly how the dispute will go when your money is already in China.

Alibaba and 1688 profile warning signs

Platform badges give a false sense of security. 'Gold Supplier' and 'Verified' status mostly confirm that a company paid for membership and passed a basic check, they are not a guarantee of quality, honesty, or even that the company makes what it lists. Treat them as a starting filter, not a seal of approval.

Read the profile the way an underwriter would. How many years has the account actually been trading on the platform, versus how long the company claims to have existed? Does the product range make sense for one factory, or is it a scattergun catalogue of unrelated items, a classic trading-company tell? Check whether the transaction history and response data look consistent with a real, active exporter. On 1688, prices are usually quoted for the domestic Chinese market, so a number that looks far cheaper than the Alibaba equivalent is not a hidden bargain; it often excludes export packing, documents, and the margin a sourcing agent or trading company would add.

Be especially wary of deals that are dramatically below every other quote. Underpricing is the most common bait in supplier scams, and it almost always means a corner is being cut somewhere, quality, materials, or the supplier's intention to deliver at all.

• Treat 'Gold Supplier' and 'Verified' as a filter, not proof
• Compare years on the platform against claimed company age
• A scattergun, unrelated product range usually signals a reseller
• Prices far below every other quote are a warning, not a win
• Requests to pay outside the platform remove your protection

Ask for videos, certifications and references

Documentation is easy to fake and easy to verify, so always verify. If a supplier sends a certificate, CE, RoHS, FDA, ISO, BSCI, or a test report from a lab like SGS, TÜV, or Intertek, note the certificate number and the issuing body, then confirm it directly on the lab's or certifier's own system. A genuine report names the exact product, model, and applicant; a borrowed one is often for a similar item from a different company, which tells you the supplier does not hold the certification themselves.

Live video remains your most powerful tool. Beyond the factory walk-through, ask to see your specific raw materials, a packed carton, and finished units close up. References matter too: ask for two or three current overseas customers in your market and actually contact them. The questions worth asking are about reliability under pressure, did orders ship on time, how were defects handled, were there hidden costs, not whether the supplier is 'good', which everyone will say.

A supplier with nothing to hide welcomes these requests. Reluctance, delays, or vague answers about certifications and references are a signal in themselves.

When you cannot run the verification yourself

If you do not speak Chinese, cannot work Chinese business hours, or the deposit is simply large enough that you want a second pair of eyes on it, hire a third-party inspector for a one-day factory audit. On a new supplier it is the best few hundred dollars in sourcing.

A real audit gets you an inspector physically standing on the site, which no amount of video can fully replace:

• Photos and video timestamped that day, on site, by someone working for you
• Verified machine count, headcount and year founded
• Confirmation that the address on the business licence is where the inspector actually stood
• A written report, and usually a short voice summary of what they thought

A one-day on-site audit in mainland China typically runs 200 to 800 dollars depending on the city, the size of the factory and how detailed you want the report. The established names are SGS, Bureau Veritas, Intertek and QIMA, formerly AsiaInspection. Any competent sourcing agent in Guangzhou, Yiwu or Shenzhen will also do them, ourselves included. Set against a deposit you would never see again, the maths is not close.

Order a sample before you commit to bulk

A free sample is a marketing tool; a paid, production-specification sample is a commitment you can hold in your hand. Always pay for samples made to your exact requirements, and order from the same line that would run your bulk order, not a polished showpiece built by hand to win you over. The point is to see what mass production will actually look like.

Inspect the sample against a written specification, not a vague mental image. Measure dimensions, check materials and weight, test function, and photograph everything from multiple angles. When you approve it, approve it in writing and keep one unit sealed as your 'golden sample', the physical reference you will hold every production run against. This single habit prevents the most common dispute in sourcing, where the bulk goods quietly drift from what you agreed.

For higher-value or technical products, consider ordering samples from two or three shortlisted suppliers at once. The difference in quality, communication, and turnaround time during the sample stage is the clearest preview you will get of how each one will behave when real money and real deadlines are on the line.

• Pay for samples built on the real production line, not by hand
• Inspect against a written spec, measure, test, photograph
• Approve in writing and seal a 'golden sample' for reference
• Sample two or three suppliers to compare before deciding

Why inspection and contract terms matter before the deposit

Verification is not finished when the supplier passes your checks, it is finished when your payment is structured so that passing checks is the only way they get paid in full. Never pay 100 percent up front. A balanced arrangement, such as a deposit with the balance released only after a passed pre-shipment inspection, keeps both sides honest and gives you leverage at the exact moment you need it most: when the goods exist but have not yet left China.

Agree the right to a third-party inspection in writing before you send a cent, and book it for after production but before the balance is paid. An inspector checks your goods against the golden sample and an agreed quality standard, catching problems while you still hold the money. A supplier who resists allowing an independent inspection is telling you something important. Equally important: pay to the registered company bank account, never to a personal account or a sudden 'new' account, which is the hallmark of both fraud and email-interception scams.

Put the deal in a clear contract or purchase order covering specifications, quantity, price, lead time, packaging, the quality standard, inspection rights, and what happens if the goods fail. None of this is bureaucracy, it is the documentation that turns a dispute from a loss into a negotiation. Running this full process on every order is precisely what a sourcing partner like Summit Sourcing does day to day, but whether you do it yourself or delegate it, the sequence is the same: verify first, sample second, inspect third, and only then release the balance.

• Never pay 100 percent up front, split deposit and balance
• Secure inspection rights in writing before paying anything
• Release the balance only after a passed pre-shipment inspection
• Pay the registered company account, never a personal one
• Document specs, quality standard and remedies in a contract

Eight red flags that mean stop

Individually, any one of these has an innocent explanation. Two or more together, and the correct move is to end the conversation and go back to your shortlist.

• Refuses or repeatedly postpones a live video walkthrough
• Factory photos appear on another company website in a reverse image search
• Business licence scope does not match what they claim to manufacture
• Registered capital implausibly small for the category they claim to work in
• Registered address resolves to a residential building, a shopping mall or an empty plot
• Bank account in a different name from the registered company, or a personal account
• WeChat-only communication, with no business email and no company website
• Pressure to wire quickly because of year-end, Chinese New Year, a factory holiday, or a raw material price rise next week

What happened to the London client

A client in London was two days from wiring 34,000 dollars. I told him to message the supplier that night and ask for a live walkthrough the next morning. Nothing elaborate: the entrance sign, the production floor, the planning board. Twenty minutes.

The next morning, the factory manager was sick. The morning after that, the signal at the factory was bad. On the third day his messages stopped being answered, and by the end of the week the WhatsApp number had blocked us. He kept his 34,000 dollars. Three weeks later we found him a real OEM in Foshan, ran the same protocol, passed every step, and the first batch shipped on time.

This is not a rare story. We catch two or three of these a year from new clients who came to us just in time. Thirty minutes of due diligence is the whole distance between a normal first order and a deposit you do not get back.
