Supplier verification is the first line of defense for any B2B importer. Yet many buyers skip it — and pay the price later.

Here are 5 verification steps you can complete without leaving your office:

1. Check Business Registration 
Every legitimate Chinese company has a Unified Social Credit Code (统一社会信用代码) — an 18-digit number.

• Ask the supplier for a copy of their business license

• Cross-check the company name on China's National Enterprise Credit Information Publicity System (gsxt.gov.cn)

• Confirm the registered capital, business scope, and establishment date

Red flag: Supplier refuses to share their license, or the company name doesn't match the bank account.

2. Verify Factory Status (工厂 or Trading Company?)
Many "factories" on B2B platforms are actually trading companies. This isn't always bad, but you should know who you're dealing with.

• Ask for a factory video call (not pre-recorded)

• Request photos of the production line, warehouse, and equipment

• Check if their business scope includes "manufacturing" (生产) or only "sales" (销售)

Red flag: They can't do a live video call, or the "factory" looks like an office.

3. Request Product Samples
Samples are the most reliable way to assess quality before committing to a bulk order.

• Order 1–3 samples from 2–3 different suppliers

• Test materials, dimensions, packaging, and functionality

• Compare against your target market's standards

Red flag: Supplier refuses to send samples, or samples differ significantly from product photos.

4. Test Communication & Responsiveness
A reliable supplier responds quickly and answers questions directly.

• Ask technical questions about materials, MOQ, and lead times

• Request custom packaging or branding options

• Observe how they handle follow-up questions

Red flag: Vague answers, slow responses (24+ hours), or pressure to pay immediately.

5. Use Escrow or Trade Assurance
Never wire money directly to a supplier's personal account.

• Use platform escrow (Alibaba Trade Assurance, etc.)

• Or use a third-party inspection service before final payment

• For large orders, consider a Letter of Credit (L/C)

Red flag: Supplier insists on direct bank transfer to a personal account.
