Zhenbao Standard: Professional Factory Audit & Supply Chain Verification
“Your Eyes and Ears in Hangzhou, China”
Buying from a distance involves risks. Zhenbao Trading eliminates the uncertainty by providing a 50-Point Technical Audit for Packaging, Irrigation, and PCBA factories.
Part 1: Legal & Financial Integrity (Compliance Check)
| Audit Item | Verification Method | Why it Matters |
| Business License & Legal Rep | Database cross-check (AIC China) | Ensures the company is legally registered and active. |
| Export License (Self-run) | Customs record verification | Confirms if they can export directly or need a middleman. |
| Bank Account Verification | SWIFT/Financial consistency check | Prevents payment fraud to “personal” or “shell” accounts. |
| Certifications (CE, ISO, UL) | Certificate number tracking | Ensures the factory meets your local safety and quality laws. |
Part 2: Production & Technical Capability (Hard Power)
| Audit Item | Verification Method | Zhenbao Expert View |
| Machine Asset List | Physical count & Brand check | Are they using high-end SMT lines (e.g., Yamaha, Fuji) or old tech? |
| Clean-Room Standard | Air particle measurement (for PCBA/Food) | Essential for high-reliability electronics and hygiene. |
| R&D Team Strength | Interview with lead engineers | Can they handle your custom (OEM/ODM) technical requirements? |
| Lead-Time Accuracy | Review of past 6 months’ shipping logs | Can they actually deliver on time during peak seasons? |
Part 3: 5-Stage Quality Control (The Core)
| QC Stage | Audit Focus | Evidence Provided |
| IQC (Incoming) | Raw material source (Chips, Sensors, Steel) | Photo of material certificates and warehouse storage. |
| IPQC (In-Process) | First-piece inspection on the line | Video of the 1st unit being tested before mass run. |
| Testing Equipment | AOI, X-Ray, Pressure & Leak testing | Photo of the calibration label on the testing machine. |
| OQC (Outgoing) | Final batch sampling (AQL Standard) | Detailed photo report of the actual finished goods. |
| Burn-in/Aging Test | 24-72 hours stress test logs | Proof that the electronics/motors won’t fail after 1 day. |
Part 4: Logistics & Sustainability (Soft Power)
| Audit Item | Focus |
| Warehouse Management | FIFO (First-In, First-Out) implementation to prevent aging stock. |
| Packaging Strength | Drop-test simulation for maritime transit (Seaworthy packaging). |
