Hi, I’m William — a verified exporter of genuine BYD, Geely, Chery, and Haval OEM parts from China.
Over the years, I’ve heard many stories from workshops and distributors who lost money to fake suppliers — missing shipments, poor quality, or even disappearing after payment.

So how do you tell if a supplier is genuinely reliable?
Here are five proven signs — all based on real cases I’ve encountered while helping clients secure safe, verified supply chains.

1️⃣ Verified Business Credentials and Export History

A legitimate supplier should provide:

• Chinese business license with a matching company name on their bank account.

• Customs export registration () — only registered companies can legally export auto parts.

• Invoice and VAT documents matching their legal entity.

Case Example:
A Nigerian workshop once shared a “supplier” contact that only used a Gmail address and private bank account.
I checked the Chinese registry — no export license, no legal entity. That’s a red flag.
Always ask for official documents before payment.

2️⃣ Physical Address and Factory Visit Proof

Reliable suppliers don’t hide their location.
They can share:

• Warehouse photos or videos showing packaging and labeling.

• Google Maps or Baidu Maps screenshots of their facility.

• Video call verification before large orders.

My practice: Every international client receives photos and packaging confirmation videos before shipment.
It’s a simple way to prove we’re real, not virtual.

3️⃣ Transparent Communication and Documentation

A professional exporter provides:

• Formal quotations with OEM numbers, quantities, and terms.

• Invoice + proforma invoice in both English and Chinese.

• Packing lists, airway bills, and export customs records upon request.

If a supplier refuses to provide documentation, be cautious.
Transparency is a habit — not an optional favor.

4️⃣ Real Customer References and After-Sales Commitment

Reliable suppliers have satisfied clients who are willing to confirm their experience.
Ask for reference contacts, or check social media (LinkedIn, WhatsApp status updates) for shipment records.

Case Example:
A Saudi workshop contacted me after being left with fake BYD sensors from a reseller.
We replaced them with verified OEM modules and provided post-sale diagnostic support — now that client orders exclusively through me.

That’s the difference between a seller and a partner.

5️⃣ Consistent Contact and Service Availability

If your supplier replies fast before payment but disappears afterward — that’s not reliability.
A genuine supplier maintains communication throughout the transaction and beyond.

You can always reach me directly on WhatsApp: +86 18669778647 — before, during, and after delivery.
That’s how long-term trust is built.

Conclusion

China has thousands of parts sellers, but only a small fraction are verified exporters with transparent operations.
By checking these five signs — credentials, location, documentation, references, and service consistency — you’ll avoid scams and build a reliable partnership.
