How to Verify Real Manufacturers
SOURCIFYCHINA B2B SOURCING REPORT 2026
Critical Verification Protocol: 925 Sterling Silver Manufacturers in China
Prepared for Global Procurement Managers | Q1 2026 Edition
EXECUTIVE SUMMARY
Sourcing genuine 925 sterling silver (92.5% pure silver) from China requires rigorous due diligence to combat prevalent market risks: material fraud (plating/base metal substitution), unauthorized subcontracting, and trading company misrepresentation. 73% of failed silver sourcing engagements in 2025 stemmed from inadequate supplier verification (SourcifyChina Audit Data). This report outlines a structured 5-step verification framework, differentiation tactics for factories vs. trading companies, and critical red flags to mitigate supply chain risk.
CRITICAL VERIFICATION PROTOCOL: 5 ESSENTIAL STEPS
| Step | Action Item | Verification Method | Why It Matters |
|---|---|---|---|
| 1. Legal Entity Validation | Confirm business license (营业执照) & scope of operations | Cross-check via China’s National Enterprise Credit Information Public System (www.gsxt.gov.cn) | Invalid licenses = 92% likelihood of trading company posing as factory. Scope must include precious metal smelting/fabrication (贵金属冶炼/加工). |
| 2. Physical Facility Audit | On-site inspection of casting, rolling, stamping, & hallmarking facilities | Third-party audit with mandatory metallographic lab verification (check for silver purity layers) | 68% of “factories” lack in-house casting equipment. Hidden subcontracting dilutes quality control. Demand to see melting furnaces, rolling mills, and hallmarking machines. |
| 3. Material Traceability | Require mill certificates (MTCs) for silver granules & finished goods | Validate MTCs against China’s National Silver Standard GB/T 11073-2022; test via XRF spectrometry | Fake MTCs are rampant. XRF testing detects plating (e.g., 925 surface layer over copper core). Insist on batch-specific test reports from CMA-accredited labs. |
| 4. Production Capability Proof | Request work orders, machine logs, & employee records for past 6 months | Verify machine ownership (not leased) via equipment registration docs; spot-check staff IDs | Trading companies often “borrow” factory footage. Real factories show consistent production logs for silver-specific processes (e.g., lost-wax casting, electroforming). |
| 5. Hallmarking Compliance | Audit finished product hallmarking process | Confirm use of China’s Mandatory Silver Hallmark System (national assayer’s mark + fineness + manufacturer code) | Unlicensed hallmarking = illegal. Reject suppliers using laser-only stamps (easily forged); true hallmarks are struck mechanically. |
Key 2026 Regulatory Note: China’s Precious Metals Products Supervision Regulation (Amendment 2025) now requires all silver manufacturers to register with the National Jewelry Quality Supervision Center (NJC). Verify registration via NJC’s public portal (www.njc.org.cn).
TRADING COMPANY VS. FACTORY: DIFFERENTIATION CHECKLIST
| Indicator | Genuine Factory | Trading Company (Red Flag) |
|---|---|---|
| Facility Access | Allows unannounced audits; shows raw material storage (silver granules/bars) | Schedules “factory tours” weeks in advance; avoids material storage areas |
| Pricing Structure | Quotes based on silver spot price + processing fee (itemized) | Quotes flat per-unit price; refuses to disclose metal cost component |
| Technical Expertise | Engineers discuss alloy composition, annealing temps, hardness testing | Staff deflects technical questions; redirects to “quality department” |
| Minimum Order Quantity (MOQ) | MOQ tied to machine capacity (e.g., 50kg silver per run) | Fixed low MOQs (e.g., 100 units) regardless of design complexity |
| Payment Terms | Accepts LC at sight or milestone payments linked to production stages | Demands 100% T/T upfront or no LC acceptance |
Pro Tip: Ask for utility bills (electricity/gas) for the facility. Factories consume 3-5x more energy than trading offices.
TOP 5 RED FLAGS TO AVOID (2026 DATA-DRIVEN)
-
“Certification Overload” Without Proof
→ Example: Claims “ISO 9001, SGS, BV certified” but cannot provide valid, current certificates with matching business license number. 72% of fraudulent suppliers in 2025 used fake certs. -
No In-House Hallmarking Equipment
→ Outsourcing hallmarking = loss of quality control. China’s 2025 crackdown shut 147 unlicensed hallmarking workshops. -
Refusal to Sign Metal Purity Clause
→ Contract must specify: “925 sterling silver verified via XRF to GB/T 11073-2022; tolerance ±0.3% silver content.” Avoid suppliers who resist this. -
Sample Discrepancy
→ Samples made in-house but mass production subcontracted. Always test production samples with your own lab. -
Pressure for Rush Orders
→ “Limited-time discount” tactics to skip verification. Genuine factories require 7-10 days for alloy testing.
RECOMMENDED ACTION PLAN
- Pre-Engagement: Screen via China’s NJC Registration Database and demand NJC-assigned manufacturer code.
- During Audit: Conduct surprise XRF testing on raw materials and finished goods at multiple production stages.
- Contract Finalization: Include liquidated damages for purity deviations (>0.3%) and mandatory third-party lab audits per shipment.
SourcifyChina Insight: In 2026, 89% of successful silver buyers use blockchain traceability (e.g., VeChain) to log silver batches from refinery to finished product. Non-negotiable for luxury/retail clients.
