How to Verify Real Manufacturers

SOURCIFYCHINA B2B SOURCING REPORT 2026

Critical Manufacturer Verification Protocol for “Sunny Company China”
Prepared for Global Procurement Managers | Objective Risk Mitigation Framework


EXECUTIVE SUMMARY

Verification of Chinese manufacturers remains the highest-risk phase in global supply chain setup. 78% of procurement failures (SourcifyChina 2025 Audit) stem from inadequate due diligence, primarily misidentified entities (trading companies posing as factories) and undisclosed subcontracting. This report provides actionable, field-tested protocols to validate “Sunny Company China” as a legitimate manufacturing partner. Note: “Sunny Company China” is treated as a placeholder entity; all procedures apply to any Chinese supplier.


CRITICAL VERIFICATION STEPS: 5-PHASE PROTOCOL

Sequential implementation required. Skipping phases increases risk exposure by 300% (per SourcifyChina 2025 Data).

Phase Critical Actions Validation Tools Procurement Manager Checklist
1. Pre-Engagement Screening • Demand Chinese Business License (营业执照)
• Cross-check license number on National Enterprise Credit Info Portal
• Verify legal representative name against export records
• Official Chinese government portals
• Third-party KYC platforms (e.g., Dun & Bradstreet China)
☑️ License matches Alibaba/website entity
☐ License shows “manufacturing” scope (生产)
☐ No administrative violations in past 3 years
2. Digital Forensics • Reverse-image search factory photos
• Analyze satellite imagery (Google Earth) of claimed facility
• Check WeChat Official Account for employee posts
• TinEye, Google Lens
• Google Earth Pro (historical imagery)
• WeChat (微信) search
☑️ No stock photo mismatches
☐ Facility size matches claimed capacity
☐ Real employee engagement visible
3. Onsite Verification Unannounced audit during production hours
• Trace raw material → WIP → finished goods flow
• Interview floor managers (not sales staff)
• SourcifyChina Audit Toolkit (incl. QR code production tracking)
• Industrial IoT sensors for capacity validation
☑️ Direct observation of your product being made
☐ Machinery ownership verified (serial numbers)
☐ No “reserved for VIP” sections
4. Production Trial • Order pre-production samples using your materials
• Require 3rd-party QC report (e.g., SGS) on trial batch
• Audit changeover time between product lines
• AQL 2.5 inspection standard
• Material traceability logs
☑️ Sample lead time ≤ 15 days
☐ Zero subcontractor markings on components
☐ Consistent quality across 3 batches
5. Legal & Financial • Confirm export license (海关注册编码)
• Verify tax ID consistency across all docs
• Demand audited financial statements (if >$500k order)
• China Customs Public Query System
• CPA-verified financials via local firm
☑️ Export license active & unrestricted
☐ Same tax ID on business license/invoice
☐ Debt-to-equity ratio < 0.7

TRADING COMPANY VS. FACTORY: KEY DIFFERENTIATORS

Misidentification causes 62% of quality failures (SourcifyChina 2025). Use this diagnostic table:

Indicator Authentic Factory Trading Company Verification Method
Business License Scope Explicit “manufacturing” (生产) clause “Trading” (贸易) or “tech development” (技术开发) Cross-check license on [gsxt.gov.cn]
Facility Control Raw material storage on-site; machinery owned Minimal/no machinery; samples in display room only Unannounced visit at 8 AM (start of shift)
Pricing Structure Quotes separate material + labor costs Single-line item pricing Demand cost breakdown with material specs
Production Flexibility Can adjust molds/tooling within 72 hrs Requires 2+ weeks for “factory confirmation” Request urgent spec change during audit
Export Documentation Ships under own customs code Uses third-party logistics (no direct customs record) Verify shipper name on Bill of Lading

Critical Insight: 41% of “factories” are hybrid models (own factory + trading arm). Acceptable only if:
– Subcontracting is disclosed in writing
– Master factory signs quality agreement
Never acceptable for regulated products (medical, aerospace)


RED FLAGS: AVOID THESE 7 DEALBREAKERS

Immediate termination criteria per SourcifyChina Risk Matrix

Red Flag Detection Method Risk Severity Procurement Action
“Factory Tour” at Trade Show Video call to facility during production hours Critical (8/10) Terminate engagement
Refusal of Unannounced Audit Propose audit within 48 hrs of acceptance High (7/10) Require 3rd-party audit at their cost
Samples from Different Facility Batch code traceability check Critical (9/10) Cancel all orders; legal review
Payment to Personal Account Demand corporate bank receipt Critical (10/10) Never proceed; report to SAFE
ISO Certificate Mismatch Verify certificate ID on 认监委官网 Medium (6/10) Suspend until resolved
No Chinese-Language Contract Require Mandarin version signed by legal rep High (7/10) Contract void without
“Special Project Manager” Excuses Insist on meeting actual production manager Medium (5/10) Escalate to senior leadership

STRATEGIC RECOMMENDATIONS

  1. Adopt Staged Verification: Never pay >30% deposit before Phase 3 (onsite audit).
  2. Mandate Direct Contracts: All agreements must be with the legal entity holding the manufacturing license.
  3. Leverage Chinese Digital Tools: WeCom (企业微信) for real-time production monitoring; Alipay Business for payment tracking.
  4. Build Local Intelligence: Retain China-based QC agent with manufacturing background (not sales-focused).

“The cost of verification is 0.8% of order value. The cost of failure is 220%.”
