Seven Warning Signs of a Supplier You Should Walk Away From

Outright fraud is rarer than the internet suggests. What is common is something less dramatic and more costly: a supplier who is out of their depth, who takes the order anyway, and who improvises when things go wrong.

The signals are usually there early. Here are the seven we act on.

1. The price is meaningfully below everyone else's

If four factories quote within 8% of each other and a fifth is 35% cheaper, the fifth is not more efficient. They have made a different assumption about specification — thinner material, lower-grade component, no certification, different packing — or they are quoting to win and intending to renegotiate after the deposit.

Ask them, in writing, to confirm the specification line by line. A genuine supplier confirms. An improvising one becomes vague.

2. They answer technical questions with commercial answers

You ask about wall thickness; they reply that quality is guaranteed and they have many customers in your country. You ask about plating microns; they reply that the price is very good.

This is the clearest single signal. A factory knows its own numbers. A reseller pretending to be a factory reaches for reassurance instead — because they would have to ask someone else, and they do not want you to know that.

3. The bank account is not in the company's name

Payment should go to a corporate account matching the name on your proforma invoice. Requests to pay a personal account, a Hong Kong entity with a different name, or "our agent's account" should stop the conversation until fully explained.

This is also the most common vector for the interception scam: an email account is compromised, and a message arrives late in the process announcing "new bank details." Always verify banking changes by voice or video call, on a number you already had — never on the number in the email announcing the change.

4. They will not send a factory video or accept a visit

You do not need to fly to China to check this. Ask for a short unedited walkthrough — the production line, your product in progress, the loading area. A real factory finds this trivially easy. Reluctance, endless postponement, or a suspiciously polished corporate video used instead all mean the same thing.

5. Certificates that do not survive checking

Test reports and certificates carry issuing body names, report numbers and dates. Most accredited laboratories provide a verification portal. A surprising proportion of documents sent to buyers are for a different product, expired, or issued to a different company.

Check the report number against the issuing body. It takes five minutes.

6. Sudden urgency

"Price valid today only." "The mould slot is taken tomorrow." "Raw material is increasing next week, confirm now."

Raw material prices genuinely do move, and capacity genuinely does book out — but a real supplier explains the mechanism and gives you a date. Manufactured urgency is designed to move you past due diligence, and its presence is more informative than its content.

7. They agree to everything

A supplier who accepts every specification, every deadline, every quantity and every price without a single pushback is not being accommodating. They are avoiding a conversation.

The best factories we work with argue with us. They say a tolerance is impossible at that price, that a colour will not hold in that material, that a deadline is unrealistic in Q1. That friction is the sound of competence.

What to do instead

None of this requires suspicion as a posture. It requires process — the same process, every time, applied to suppliers you like as well as suppliers you do not.
