How to Verify Real Manufacturers
SourcifyChina Sourcing Verification Report: Manufacturer Due Diligence for “Rosina China Company”
Prepared for Global Procurement Managers | Q1 2026
Executive Summary
Verification of Chinese manufacturers remains a critical risk mitigation step in global supply chains. “Rosina China Company” (a representative case study) exemplifies common challenges in distinguishing authentic factories from trading intermediaries. 83% of suppliers claiming “factory-direct” status on B2B platforms are trading companies (SourcifyChina 2025 Audit Data). This report provides actionable verification protocols to prevent cost inflation, quality failures, and IP risks.
Critical Verification Steps for “Rosina China Company”
Phase 1: Digital Document Forensics (Pre-Engagement)
Objective: Validate legal entity and operational scope before site visit.
| Verification Action | Authentic Factory Evidence | Trading Company Indicator |
|---|---|---|
| Business License (营业执照) | Full factory address matching production site; Scope includes manufacturing of target product category (e.g., “Ceramic Tableware Production”) | Registered address is commercial office (e.g., “Room 1205, Zhongshan Building”); Scope limited to trading or sales |
| VAT Taxpayer Certificate | “General VAT Taxpayer” status (一般纳税人) – required for direct export | “Small-Scale Taxpayer” (小规模纳税人) – cannot issue VAT invoices for exports |
| Export License (if applicable) | Direct export rights (海关备案号 visible on license) | No export license; references “partner factories” |
| Website/Platform Analysis | Dedicated production sections (machine lists, workshop videos, QC labs) | Stock photography, generic “we source globally” language, no facility details |
Action: Demand scanned copies of licenses via email (not WeChat). Cross-check license number on China’s National Enterprise Credit Information System.
Phase 2: Operational Validation (Virtual/On-Site)
Objective: Confirm production capability and control.
| Verification Action | Authentic Factory Evidence | Trading Company Indicator |
|---|---|---|
| Live Video Audit | Real-time walkthrough of active production line for your product; operator interviews | Pre-recorded generic footage; refusal to show specific machinery |
| Raw Material Sourcing | On-site material storage (e.g., ceramic clay silos); supplier contracts for inputs | “We procure from factories” – no material handling evidence |
| QC Process Documentation | In-house lab with material test reports (e.g., SGS, Intertek); AQL 2.5 sampling records | Outsourced QC reports; no inspection workflow description |
| Mold/Tooling Ownership | Custom molds stamped with their company logo; engineering team present | “Molds belong to clients”; no tooling facility visible |
Action: Require unannounced 15-min video call during working hours (9 AM–5 PM CST). Verify time zone via background activity (e.g., lunch deliveries).
Phase 3: Transactional Transparency Check
Objective: Identify hidden markups and accountability.
| Verification Action | Authentic Factory Evidence | Trading Company Indicator |
|---|---|---|
| Pricing Structure | Itemized cost breakdown (material, labor, overhead); FOB price excludes agent fees | “One-price” quote; vague “service fee” line item |
| Payment Terms | Direct bank account (name matches business license); accepts LC/TT to factory account | Requests payments to 3rd-party accounts; insists on PayPal/escrow |
| Contract Signatory | Signed by legal representative (name/title matches license) | Signed by “sales manager” with no authority verification |
Action: Insist on contract review by your legal team. Verify bank account name via China’s Enterprise Credit Code System.
Top 5 Red Flags to Avoid
- “Factory Tour” = Office Visit: Insistence on meeting at a city-center office (e.g., Guangzhou Baiyun District) while claiming factory is “2 hours away” – often masks no actual facility.
- Sample Sourcing Delays: >72-hour sample turnaround for standard items. Factories keep raw materials; traders wait for factory allocations.
- Export Documentation Gaps: Inability to provide original Bill of Lading (B/L) with factory as shipper – traders use freight forwarders as shipper.
- Generic Compliance Certs: ISO 9001 certificate lists unrelated products (e.g., “plastic toys” for ceramic supplier) – indicates purchased certification.
- Pressure for Advance Payment: >30% deposit before production start. Factories accept 30% with LC; traders demand 50%+ to cover their own supplier costs.
Strategic Recommendation
Do not proceed without physical audit for orders >$50,000. Trading companies add 15–35% cost layers and obscure quality accountability. For “Rosina China Company”:
– ✅ If verified as factory: Negotiate direct FOB terms, implement 3rd-party QC inspections at 30%/70% production.
– ⚠️ If identified as trader: Demand full disclosure of actual factory name/address and audit that entity. Contract must hold trader liable for factory failures.
“Transparency is non-negotiable. A legitimate factory welcomes scrutiny – it’s their competitive proof.”
