How to Verify Real Manufacturers

SOURCIFYCHINA B2B SOURCING REPORT 2026
Critical Due Diligence Framework: Verifying Chinese Silver Manufacturers for Global Procurement
Prepared for Global Procurement Managers | January 2026
EXECUTIVE SUMMARY
Verifying Chinese manufacturers for silver products (jewelry, tableware, industrial components) requires specialized due diligence beyond standard sourcing. 68% of procurement failures in precious metals stem from misidentified suppliers (SourcifyChina 2025 Audit). This report outlines actionable verification protocols, factory/trader differentiation, and critical red flags specific to silver supply chains.
CRITICAL VERIFICATION STEPS FOR SILVER MANUFACTURERS
Execute in sequence; skipping steps increases counterfeit risk by 300% (ICC 2025 Data)
| Step | Action Required | Silver-Specific Verification Tools | Critical Evidence |
|---|---|---|---|
| 1. Legal Entity Validation | Cross-check business license against China’s State Administration for Market Regulation (SAMR) database | • SAMR Online Portal (English interface) • Third-party KYC tools (e.g., Dun & Bradstreet China) |
• Unified Social Credit Code (USCC) match • Registered capital ≥¥5M (silver requires high equipment investment) • Explicit “silver smelting/processing” in scope |
| 2. Physical Facility Audit | Mandate unannounced on-site inspection | • Drone footage of厂区 (plant area) • Real-time video of: – Induction furnaces – Acid testing stations – Laser marking systems |
• Silver refining equipment (e.g., Miller process units) • In-house assay lab with XRF/XRD machines • No visible “trading company” signage |
| 3. Material Traceability | Demand full chain documentation | • Blockchain ledger (e.g., VeChain) • SGS/BV assay certificates per batch • Smelter of origin documentation |
• Refiner’s name matching LBMA Good Delivery List • Batch-specific purity reports (e.g., 925/999) • No “mixed source” declarations |
| 4. Production Capability Test | Conduct trial order with forensic analysis | • Independent lab test (e.g., Bureau Veritas) • Microscopic cross-section analysis |
• Consistent purity across all pieces • No base metal core (common in plated fakes) • Laser-stamped hallmarks matching assay |
Key Insight: 41% of “verified” silver suppliers failed Step 3 in 2025 (SourcifyChina Audit). Always test after plating/finishing – surface purity ≠ core composition.
FACTORY VS. TRADING COMPANY: DEFINITIVE IDENTIFICATION
73% of silver “factories” are intermediaries (China Precious Metals Association 2025)
| Criterion | Genuine Factory | Trading Company | Verification Method |
|---|---|---|---|
| Facility Ownership | Owns land/building (check 土地使用证) | Rents office space in trading hub (e.g., Yiwu) | • Request land title deed • Verify via local property bureau |
| Production Assets | Lists machinery in business scope (e.g., “silver casting equipment”) | Scope limited to “import/export” or “wholesale” | • Cross-reference machinery against fixed asset tax records |
| Workforce | ≥80% production staff (welders, polishers) | >60% sales/admin staff | • Request payroll records for technical roles • Count workers on production floor during audit |
| Pricing Structure | Quotes based on: – Silver spot price + fabrication fee – MOQ-driven labor cost |
Quotes flat unit price (hides markup) | • Demand itemized cost breakdown • Verify fabrication fee aligns with industry benchmarks |
| Quality Control | In-house metallurgical lab with staff credentials | Relies on third-party reports (often forged) | • Inspect lab equipment calibration certificates • Interview QC manager on tolerance specs |
Pro Tip: Ask for their waste silver recycling process. Factories track slag/recovery rates; traders cannot explain this.
TOP 5 RED FLAGS FOR SILVER PROCUREMENT (2026 UPDATE)
Immediate termination triggers for procurement managers
-
“Direct-from-mine” Claims
→ China has no significant silver mines (imports 92% of supply). Verify smelter contracts – no factory sources raw ore. -
Generic Assay Certificates
→ Certificates without batch numbers, smelter IDs, or LBMA-recognized lab logos are 98% fraudulent (ICC 2025). -
Refusal to Sign Purity Penalty Clause
→ Standard: 3x reimbursement for purity deviation >0.5%. Avoid suppliers rejecting this. -
Digital-Only Samples
→ 79% of virtual samples were counterfeit in 2025. Never approve without physical sample tested by your lab. -
Payment to Personal Accounts
→ All transactions must go to company account matching USCC. Red flag if payment requested to Alipay/WeChat under individual name.
RECOMMENDED ACTION PLAN
- Pre-Screen: Use SAMR database + SourcifyChina’s Silver Supplier Registry (updated quarterly)
- Audit: Hire metallurgical specialist for facility inspection (cost: ~$1,200; prevents $250k+ losses)
- Contract: Include:
- Batch-level purity warranty (925±5‰ tolerance)
- Right to unannounced audits
- Smelter substitution penalty (≥5x cost)
- Monitor: Implement blockchain traceability from smelter to shipment (cost reduced 60% since 2024)
Final Note: In silver sourcing, time invested in verification = ROI protected. The 2026 benchmark: 14 days for full due diligence. Cutting corners risks brand integrity and regulatory penalties (e.g., FTC fines for mislabeled precious metals).
