China Trade Scam Prevention
Real cases and self-defense — knowing this stops 90% of fraud

Hello, this is GreenFrog Seoul.

Anyone who starts sourcing from China eventually has a moment of asking, "Wait, is this a scam?" Every year, countless overseas buyers lose anywhere from a few thousand to hundreds of thousands of dollars to China trade fraud.

"The sample was perfect, but the mass production goods were a completely different product."
"I sent a 30% deposit and they vanished."
"I visited the factory, only to find out later it was rented by a middleman."

Today we'll cover the 7 most common scam patterns in China trade and the concrete countermeasures for each, with real cases. This single guide can prevent the vast majority of fraud before it happens.


Scam #1: Advance Payment Fraud

The classic — and still the most common — fraud pattern, with the largest aggregate losses every year.

How it works

Real case

A buyer found a Bluetooth earbuds factory on 1688 and ordered 5,000 units. The unit price was 20% below market and the factory said it was a "special discount for large volume." After wiring USD 14,000 as a deposit via T/T, the delivery date came and a message arrived saying "delayed two weeks due to raw material shortage." Two weeks later: "in QC inspection." Then communication ceased entirely.

Prevention

⚠️ "20%+ below market price" is a fraud signal A legitimate factory has no reason to sell below cost. An abnormally cheap quote is either advance-payment fraud or a spec downgrade (cheap components substituted) at production. When the price looks too good, your first question should be "Why is it this cheap?"

Scam #2: Bait and Switch (Quality Substitution)

The sample is perfect — but mass production goods are something completely different. This is the most subtle and most frequent scam in China sourcing.

How it works

Real case

A buyer ordered leather bags. The sample was genuine full-grain bovine leather. When 2,000 mass-production units arrived, they were synthetic PU leather. The exterior looked similar, but within three months the surface began cracking, triggering a flood of customer complaints.

Prevention

💡 Use the "Golden Sample" system Prepare two approved sample sets — one held by the buyer, one by the factory. Mass production is inspected against the golden sample, and the contract states that any deviation is the factory's responsibility. With both parties' signatures, dates, and seals on the golden sample, you also gain legal evidentiary value.

Scam #3: Fake Factory / Trading Company Fraud

You think you're dealing with a factory — but it's actually a trading company, or no factory exists at all.

How it works

Prevention

⚠️ "Trading company = scam" is not true Honest trading companies are useful for small orders or multi-category sourcing. The problem is when a trading company poses as a factory and adds a hidden direct-production margin. A trading company that openly identifies itself and charges a transparent service fee is perfectly legitimate.

Scam #4: Short Shipment (Quantity / Weight Cheating)

Shipping fewer units than ordered, or under-weighing weight-based products.

How it works

Prevention


Scam #5: IP Theft

The factory steals the buyer's designs, molds, or technical materials and either sells the same product directly or supplies it to competitors.

How it works

Prevention

⚠️ An NDA alone is not enough An NDA gives you a "breach of contract" claim in disputes, but actually winning an NDA suit in China is extremely difficult. Real protection requires NDA + Chinese patent/trademark registration in parallel.

Scam #6: Payment Fraud

Fraud during the payment process. Email-hijacking BEC (Business Email Compromise) attacks have surged in recent years.

How it works

Prevention

⚠️ BEC fraud is a multi-billion-dollar global crime Per FBI reports, global BEC losses exceed several billion dollars per year. An email saying "our account has changed" is fraud 99% of the time. Always confirm by phone before wiring.

Scam #7: Fake Certificates / Test Reports

Forged product certifications (CE, FCC, KC, etc.) or fake test reports.

How it works

What to Do If You've Been Scammed

Prevention is best, but if you've already been defrauded, speed is critical.

Immediate actions

  1. Preserve evidence: Save all conversations (WeChat, email), the contract, payment records, and photos immediately
  2. Contact your bank: Within 24–72 hours of T/T, request a wire recall
  3. Report to local police: File a complaint with the Public Security Bureau (公安局) in the factory's jurisdiction. Online reports are also accepted
  4. Reach out to your trade office: Consult your country's commercial mission in China (e.g., KOTRA for Korea)

Legal recourse

💡 Speed is everything in China fraud response Once you suspect fraud, move fast. Given time, fraudsters withdraw funds, dissolve the company, and destroy evidence. Bank wire recall has a ~72-hour golden window. Don't hesitate — act immediately.
