How to Vet a Chinese Supplier Before Sending a Cent
The most expensive email a new importer ever sends is the one transferring a deposit to a supplier they never checked. From Auckland or Christchurch you can't drop in to see the factory, so your protection is a vetting process — a series of cheap, fast checks that scammers and fake factories can't pass. Run every prospective supplier through this before a single dollar leaves your account.
Start with the platform filters
On Alibaba, filter for Gold Supplier, Onsite Check and Assessed Supplier together. Each represents money and scrutiny a scammer won't invest in. On Global Sources, look at the verified data: exhibiting history and named customers. This first pass eliminates most of the worst candidates in thirty seconds. It can also exclude some genuine young factories, so if results are thin, relax one filter at a time — but tighten your later checks to compensate.
Read the profile like a detective
A supplier's own profile leaks the truth if you know where to look:
- Management standards. No ISO 9001 or BSCI listed? Skip them. If it is listed, ask for the certificate and check the company name and address on it match the supplier you're talking to. Middlemen don't invest in management standards.
- Category breadth. A "manufacturer" selling everything from kitchenware to power tools to phone cases is a trading company. Real factories are specialists.
- Numbers that don't add up. Registered capital of 50,000 RMB against claimed turnover of US$50 million is fantasy. Huge turnover with 15 staff is equally fishy.
- Scale and age. A well-organised factory typically runs 200+ employees — say 160 workers, 30 sales staff, 10 engineers, 10 managers. Factories younger than about five years deserve extra caution.
- The company-name convention. Trading companies usually register with their hometown in the name; manufacturers use the province. We cover this trick in detail in its own post.
Ask for the documents
Now move to active verification. Email the supplier and request: a copy of their business licence (it will be in Chinese — the refusal to send it is the signal, not the content); their factory standard certificates (ISO 9001 at minimum); which third-party test laboratories they use; factory photos or a company presentation; and their customer list and main export markets.
Two things to watch in the answers. First, be cautious if they only ever work with Chinese test and inspection companies — you want suppliers accustomed to international third-party scrutiny. Second, look at their markets. If they already supply Australia, the UK, Germany or the US, they've likely passed the audits and testing those markets demand, which is a strong proxy that they can meet New Zealand requirements too — things like an SDoC for declared electrical articles and Radio Spectrum Management compliance for wireless products. If they've never exported to a first-world market, expect to educate them at your own risk.
Send a short vendor profile form asking for production capacity, worker/engineer counts, main customers, certifications and turnover. Professional suppliers fill it in without fuss.
The killer test
Two checks are almost impossible for a middleman to fake. First, ask them to produce a customised sample — something they don't have sitting on a shelf. Second, ask for a video call where they walk you through the factory live. A genuine manufacturer will happily show off the production line; a trader will stall, excuse and deflect. Follow up with a phone call and grill them on customers, annual capacity and certifications. You're building a gut feeling as much as a file of evidence.
And watch the communication itself. If replies are slow, fragmented or ignore half your questions at the enquiry stage — when they're trying to win your business — it will be worse mid-order when they already have your deposit. Eliminate the weakest communicators early.
The walk-away triggers
Some findings end the conversation immediately: a demand for 100% payment up front (legitimate suppliers accept a 30% deposit or a letter of credit); prices dramatically below every other quote; odd payment requests such as a personal bank account or Western Union; certificates whose company details don't match. The golden rule is old but reliable — if it looks too good to be true, it is. There are thousands of suppliers; never be so invested in one that you ignore a red flag.
One nuance: "trading company" is not automatically a death sentence. Many genuine factories lack an export licence and legitimately sell through an affiliated trader who handles export paperwork for a small margin. The crime isn't being a trader — it's pretending to be a factory.
Key takeaways
- Stack the free platform filters first, then verify certificates, licences and customer lists yourself — matching names and addresses on every document.
- A customised sample plus a live factory video call is the test middlemen can't fake.
- Poor communication at enquiry stage only gets worse after you've paid — cut slow repliers early.
- 100% upfront payment demands, implausible prices and mismatched certificates are instant walk-away triggers.
