---

Critical Verification Steps: Factory vs. Trading Company

Do not proceed beyond Step 3 without conclusive evidence.

Verification Step	Factory Evidence	Trading Company Indicators	Verification Method	Timeline/Cost
1. Legal Entity Verification	• Business License (营业执照) with manufacturing scope (e.g., “metal fabrication,” “sheet metal processing”) • Factory address matches production site	• License lists “trading,” “import/export,” or “sales” • Registered address is commercial district (e.g., Shanghai Pudong) vs. industrial zone	• Request scanned license + cross-check via National Enterprise Credit Info Portal • Use SourcifyChina’s License Decoder Tool (free for clients)	24–48 hrs / $0
2. Production Capability Audit	• Live video tour showing: – Raw material inventory (coils of galvanized steel/AL) – In-house stamping/welding/powder coating lines – Dedicated mailbox assembly jigs • Machinery ownership documents (e.g., CNC press brake invoices)	• Tours show “sample rooms” only • Vague answers about machinery (e.g., “We partner with workshops”) • No raw material storage visible	• Unannounced virtual audit via Teams/Zoom • Require timestamped photos of machinery nameplates • Demand production workflow video (cutting → welding → finishing)	72 hrs / $250 (virtual) or $1,200 (on-site)
3. Supply Chain Control	• Direct sourcing of raw materials (show steel mill contracts) • In-house quality lab (e.g., salt spray test reports for corrosion resistance) • Custom tooling ownership (e.g., mailbox die molds)	• “We source from Alibaba” • Cannot provide material test certificates (MTCs) • Samples lack batch traceability	• Request 3 most recent MTCs for steel/coatings • Verify lab equipment via video (e.g., film thickness gauge) • Ask for tooling registration certificates	48 hrs / $0
4. Financial Transaction Proof	• Direct payment to manufacturer’s corporate account (not personal/3rd-party) • FOB pricing breakdown (raw materials, labor, overhead)	• Requests payment to “agent” accounts • Inconsistent pricing (e.g., 30% lower than market avg.)	• Use SourcifyChina Escrow for first order • Require VAT invoice (发票) matching business license	Real-time / $0

Top 5 Red Flags for Mailbox-Specific Sourcing

Immediate disqualification criteria for apartment mailbox projects:

Red Flag	Why Critical for Mailboxes	Verification Action
“All-inclusive” sample pricing	Trading companies markup samples 200–400% to hide low-volume production costs. Mailbox samples require custom tooling – true factories charge tooling fees upfront.	Demand itemized sample cost (material, labor, tooling amortization). Reject if tooling fee < $800 for steel units.
No corrosion test data	Mailboxes face outdoor exposure; ISO 9227 salt spray certification (< 500 hrs) is non-negotiable. Trading companies omit this to cut costs.	Require recent test report showing ≥ 1,000 hrs neutral salt spray resistance. Verify lab accreditation.
Generic Alibaba product photos	Factories showcase actual production lines; trading companies use stock images. Mailbox designs (e.g., USPS STD-4B compliance) require precise engineering.	Demand photos of your mailbox model in production with time/date watermark.
“We export to 50+ countries” claim	Legitimate factories specialize (e.g., EU mailboxes = CE-certified, US = ADA-compliant). Overstated export claims indicate trading.	Request 3 verifiable export invoices (redact prices) for your target market. Cross-check with customs data.
Refusal of unannounced audit	Trading companies coordinate “staged” factory tours. Mailbox production requires consistent line capacity.	Contract clause: “Buyer may conduct unannounced audits with 24h notice.”

---

Strategic Recommendations

1. Prioritize Tier-2/3 Cities: Mailbox factories cluster in Ningbo, Dongguan, and Wuxi (vs. trading hubs like Yiwu). Labor costs are 18% lower with 30% higher retention.
2. Demand Mailbox-Specific Certifications:
3. USPS STD-4B (US)
4. EN 13724 (EU)
5. ISO 14644 (cleanroom powder coating)
6. Pilot Order Protocol: Order ≤ 50 units with SourcifyChina’s 3-Stage QC:
7. Pre-production: Material verification
8. During production: Weld point inspection
9. Pre-shipment: Dimensional tolerance check (±0.5mm)

“In 2025, 92% of mailbox failures traced to suppliers who skipped Step 2 verification. Trading companies cannot control metallurgical processes – only factories can.”
— SourcifyChina Global Sourcing Index 2026
