Every year, thousands of importers lose money to factories that don't exist, quality that doesn't meet specs, and shipments that never arrive. According to the ICC, commercial fraud costs international trade an estimated $1.5 trillion annually — and China-sourced goods account for a significant share.
The truth is: most buyers don't get scammed because the supplier was too clever. They get scammed because they skipped the verification steps.
This guide walks through a practical, bank-grade due diligence framework — the same approach CSMG uses to vet suppliers for our own LC-financed transactions.

Step 1: Validate the Company Exists (Digitally)
Before picking up the phone, verify the company has a real digital footprint.
Check the Business License
Every registered Chinese company has a Uniform Social Credit Code (USCC) — an 18-character alphanumeric identifier. Ask for it. Then verify it through:
- **National Enterprise Credit Information Publicity System** (国家企业信用信息公示系统) — [gsxt.gov.cn](http://www.gsxt.gov.cn)
- **Qichacha** (企查查) — [qichacha.com](https://www.qichacha.com)
- **Tianyancha** (天眼查) — [tianyancha.com](https://www.tianyancha.com)
What to look for:
- ✅ Company name matches your contact's business card
- ✅ Registered capital (注册资本) — be skeptical of companies with less than ¥1M registered capital for manufacturing claims
- ✅ Business scope (经营范围) — does it actually cover what you're sourcing?
- ✅ Establishment date — a factory founded 3 months ago claiming 10 years of experience is a red flag
- ✅ Legal representative matches your contact's identity
Real example: A buyer sourcing medical masks in 2020 found the supplier's USCC was registered only 2 weeks prior with ¥100,000 capital. The "factory tour" was stock video. They walked away — and later learned 30 other buyers lost their deposits to the same entity.
Cross-Check on Alibaba/Made-in-China
Even if you found the supplier through a trade show, check their Alibaba page. Verified suppliers on Alibaba have gone through on-site verification by a third party (TÜV, SGS, or Bureau Veritas).
**⚠️ Caveat:** Alibaba verification confirms the *factory exists*, not that the *product quality* is good. It's a floor, not a ceiling.

Step 2: Verify the Physical Factory
A company that exists on paper may not exist in the physical world.
Request a Live Video Call
Not a pre-recorded video. A live WeChat video or WhatsApp call where they show you:
The factory floor (machinery running)
2. The warehouse (inventory with your potential order materials)
3. The office (real people working)
4. The building exterior (Google Maps cross-reference)
Pro tip: Ask them to show a newspaper or your purchase order on screen during the call. This proves the video isn't pre-recorded.
Use Google Maps Street View
Search the company's registered address on Google Maps. A "manufacturing factory" located in a residential apartment building is a major red flag.
Third-Party Inspection
For orders over $10,000, hire an inspection company. Reputable options:
- **SGS** — $400–800 per man-day
- **Bureau Veritas** — similar pricing
- **TÜV Rheinland** — strong in industrial goods
- **QIMA** (formerly AsiaInspection) — good for small buyers
What a basic pre-shipment inspection covers:
- Quantity verification
- Product appearance and workmanship
- Dimensions and specifications
- Packaging quality
- Loading supervision

Step 3: Financial Due Diligence (The Banker's Approach)
This is where most buyers stop — and where the real risk lives.
Run a Credit Report
Chinese companies can be checked for credit history through:
- **BaiRong** (百融) — financial behavioral data
- **CreditChina** (信用中国) — [creditchina.gov.cn](https://www.creditchina.gov.cn)
- **The Supreme People's Court Blacklist** — is the company or its legal representative listed as dishonest (失信被执行人)?
Payment Terms Tell You Everything
How a supplier negotiates payment reveals their financial health:
| Payment Terms | What It Signals |
| --------------- | ---------------- |
|---|---|
| **30% deposit, 70% against BL** | Standard, reasonable for established factories |
| **100% T/T upfront** | 🚩 High risk — they need your cash to operate |
| **LC at sight** | Strong — they have banking relationships |
| **Net 30/60 after shipment** | Very strong — they trust their cash flow |
| **50% deposit, 50% before shipment** | 🚩 Margin call risk — walk away |
Verify the Bank Account Name
This is the #1 scam prevention step.
The supplier's bank account name must match their business license name exactly. If they give you a personal account (even "for tax purposes"), that's a scam 90% of the time.
**Real story:** A European buyer lost €47,000 because the supplier said "our company bank account is being upgraded, please send to our manager's personal account." The manager disappeared. The company denied any knowledge.
Use LC (Letter of Credit) When Possible
If your order value exceeds $5,000, negotiate an LC at sight payment. With an LC:
- Your bank pays the supplier's bank, not the supplier directly
- Payment only releases when shipping documents (BL, invoice, packing list, inspection cert) are verified
- The bank acts as a neutral third party
CSMG offers LC credit sales for qualified buyers — meaning we use our own banking relationships to issue LCs on your behalf, reducing your risk to near zero.

Step 4: Product Quality Verification
Don't trust samples. Verify them.
Request Samples from Production Line
Samples made specifically for you are often better than actual production. Instead:
- Ask for random samples from existing inventory
- Request the sample be packed in the same packaging you'll receive
- Have the sample tested by an independent lab
Common Quality Traps
| Trap | How to Avoid |
| ------ | ------------- |
|---|---|
| **Grade substitution** | Specify raw material grade in contract (e.g., "304 stainless steel, not 201") |
| **Specification drift** | Include acceptable tolerance ranges in every PO line |
| **Counterfeit certifications** | Verify CE/FDA/ISO certs through the issuing body, not the supplier |
| **Sample ≠ Production** | Require a pre-production sample (PPS) before mass production |
Third-Party Lab Testing
For regulated products (electronics, children's toys, medical devices, food contact materials), lab testing isn't optional. Budget $200–1,500 depending on product category.

Step 5: Visit or Send a Local Agent
Nothing replaces being there. But if you can't make the trip:
Use a China Sourcing Agent
A good sourcing agent (like CSMG) provides:
- Factory audit reports
- Price negotiation support
- Quality inspection
- Logistics coordination
- Payment escrow via LC
Cost: Typically 3–8% of order value, or a flat monthly retainer. For orders over $20,000, the peace of mind alone is worth it.
Factory Audit Checklist
If you visit or send an agent, check:
- [ ] Is the workshop actually producing your product category?
- [ ] How many workers do they have? (A "factory" with 5 workers is a workshop)
- [ ] Are there other buyers' orders in production? (shows they have real clients)
- [ ] What are their monthly production capacity in units?
- [ ] Do they have in-house QC or outsource it?
- [ ] Are environmental/worker safety regulations being followed?

Step 6: Contract Protection
What Every China Sourcing Contract Should Include
**Governing law** — specify Chinese law or international arbitration (CIETAC is standard)
2. Dispute resolution — arbitration in a neutral venue (Singapore, Hong Kong) is better than litigation
3. Inspection clause — "Inspection by [named company] on or before [date] is final and binding"
4. Force majeure — clear definition, not just "acts of God"
5. Intellectual Property — if you're sharing designs, include an NDA and IP ownership clause
6. Liquidated damages — penalty for late delivery (typically 0.5–1% of order value per week)
The Simple Rule
If a supplier refuses to sign a written contract with these elements, walk away.
