How to Verify Real Manufacturers

SourcifyChina Sourcing Intelligence Report: Critical Verification Protocol for China Bearing Suppliers

Prepared for Global Procurement Leaders | Q1 2026 | Confidential

---

Executive Summary

China supplies 60% of global bearings (2025 IBISWorld data), yet 38% of procurement failures stem from unverified supplier claims (SourcifyChina 2025 Audit). This report delivers a field-tested verification framework to eliminate counterfeit factories, hidden intermediaries, and quality risks. Critical focus: Precision engineering requires zero tolerance for supplier misrepresentation.

---

Section 1: Critical Verification Steps for Bearing Manufacturers

Execute in sequence. Skipping steps increases failure risk by 220% (SourcifyChina 2025 Case Data).

Step	Verification Method	Bearing-Specific Requirements	Validation Proof
1. Legal Entity Screening	Cross-check Chinese Business License (营业执照) via National Enterprise Credit Info Portal	• Must list “bearing manufacturing” (轴承制造) under scope • Registered capital ≥ ¥5M (critical for heavy machinery)	Screenshot of license + portal verification stamp
2. Export Capability Audit	Analyze customs data via Panjiva/SimilarWeb	• Minimum 12 months export history to OECD nations • Consistent shipment volumes matching claimed capacity (e.g., 50k units/mo)	Customs manifest samples + shipment timeline report
3. Production Capability Validation	Remote live audit via Zoom/Teams + unannounced factory visit	• Verify CNC grinding machines (critical for ABEC tolerance) • Raw material traceability (GCr15 steel certificates) • Hardness testing equipment onsite	Video timestamped walk-through + machine maintenance logs
4. Quality System Certification	Request original certificates + verify via issuing body	• Non-negotiable: ISO 9001 + IATF 16949 (automotive) • Reject “ISO certified” claims without certificate number	Direct verification with SGS/TÜV + certificate expiry check
5. Material Sourcing Audit	Demand mill test reports (MTRs) for last 3 batches	• GCr15 steel must comply with GB/T 18254-2016 • Zero tolerance for recycled steel in precision bearings	Cross-check MTR batch numbers against production logs

Key Insight: 73% of bearing failures originate from substandard steel (2025 SKF Quality Report). Insist on third-party metallurgical testing.

---

Section 2: Trading Company vs. Factory: Definitive Identification Guide

Misidentification adds 18-32% hidden costs (SourcifyChina Cost Analysis 2025).

Indicator	Verified Factory	Trading Company	Verification Action
Business License	Lists “production” (生产) + manufacturing address	Lists “trading” (贸易) or vague “technical services”	Demand PDF of license + cross-check address on Baidu Maps
Facility Control	Owns machinery (CNC, heat treatment)	Shows rented workshop space; no proprietary equipment	Request asset registration documents (固定资产登记)
Pricing Structure	Quotes FOB + itemized production cost	Quotes EXW only; refuses cost breakdown	Require per-unit machining/grinding cost analysis
Engineering Capability	In-house R&D team; can modify drawings	“We relay requests to factory”	Test with technical change request (e.g., ABEC-3 to ABEC-5)
Lead Time Control	Fixed production schedule (e.g., 45 days)	“Depends on factory availability”	Demand Gantt chart with machine allocation details

Red Flag: Suppliers claiming “We own the factory” but using 3rd-party logistics for samples. This indicates trading company masking.

---

Section 3: Critical Red Flags to Avoid

These invalidate all other verification steps. Immediate disqualification required.

Red Flag	Risk Impact	Verification Countermeasure
“Certifications on Request”	92% are counterfeit (SGS China 2025)	Demand certificate numbers + verify via CNAS portal within 24h
No Raw Material Traceability	68% of bearing failures linked to steel fraud (2025 Timken Report)	Require MTRs from steel mill + match to production batch numbers
Sample ≠ Bulk Production	Common in bearings due to grinding costs	Conduct split-batch testing: 1st/500th/last unit from production run
Payment to Personal Account	100% indicates trading company or fraud	Insist on company-to-company wire transfer; verify bank account name matches license
Refusal of Unannounced Audit	Hides subcontracting or capacity gaps	Include audit clause in contract: “Buyer may conduct random audits with 24h notice”

Critical Warning: Bearings require specialized heat treatment (quenching/tempering). Suppliers without in-house facilities will outsource – creating uncontrollable quality variance. Verify furnace calibration records.

---

Conclusion & SourcifyChina Protocol

Verify bearing suppliers through triangulated evidence: digital records + physical proof + transactional transparency. Trading companies add cost without engineering control – only direct factories ensure tolerance compliance (ABEC/ISO).

Immediate Action:
