How to Verify a Chinese Electronic Component Supplier: 7 Red Flags and 5 Green Lights

The difference between a professional Shenzhen distributor and a risky broker often comes down to a dozen small signals. Here’s exactly what to look for.

7 Red Flags

  1. No physical address on the website — or a virtual office address
  2. Pricing 40%+ below market — if it’s too good to be true, it’s counterfeit
  3. Cannot provide date code photos — legitimate distributors photograph every lot
  4. Refuses to share CoC documents — Certificate of Conformance is standard
  5. Only accepts Western Union or crypto — no buyer protection
  6. Generic email (Gmail, Hotmail) with no company domain
  7. No presence on verified B2B platforms

5 Green Lights

  1. Verified Gold Supplier on Alibaba.com with multi-year history
  2. Provides real-time inventory photos with date codes and lot numbers
  3. Accepts Trade Assurance or letter of credit — payment protection
  4. Has a professional company website with complete documentation
  5. Responds to technical questions — not just pricing emails
