| 4 | Request Sample with Traceability | Evaluate material quality and craftsmanship | Require sample with batch number; test for Al-Si alloy composition, wall thickness, and corrosion resistance (salt spray test). |
| 5 | Verify Export History & Client References | Confirm international trade experience | Request 3–5 verifiable export references. Contact references directly. Check shipping records via customs data platforms (e.g., ImportGenius, Panjiva). |
| 6 | Inspect Quality Management System (QMS) | Ensure consistent product standards | Confirm ISO 9001 certification. Request QC checklists, non-conformance reports, and AQL sampling procedures. |
| 7 | Assess R&D and Customization Capability | Evaluate engineering support for design modifications | Review in-house design team, CAD/CAM tools, mold-making facilities, and prototype lead times. |
2. How to Distinguish Between a Trading Company and a Factory
| Indicator | Factory | Trading Company | How to Identify |
|---|---|---|---|
| Business License Scope | Lists manufacturing activities (e.g., “metal casting”, “aluminum product production”) | Lists “import/export”, “trading”, “distribution” | Check NECIPS or license copy for registered经营范围 (scope of operations). |
| Facility Ownership | Owns or leases production facility; machinery under company name | No machinery; uses subcontractors | Request lease agreement, utility bills, or machinery invoices. |
| Production Control | Manages mold design, casting, finishing, and assembly in-house | Coordinates with third-party factories; limited technical input | Ask: “Who controls the casting process?” and “Where are molds stored?” |
| Pricing Structure | Lower MOQs, direct labor/mold cost transparency | Higher margins; vague cost breakdowns | Request itemized quote including material, labor, mold, and overhead. |
| Lead Time | Shorter, direct control over scheduling | Longer, dependent on factory availability | Compare quoted lead time with industry benchmark (e.g., 25–35 days for cast aluminum mailbox). |
| Workforce | Employs foundry technicians, QC inspectors, mold engineers | Employs sales and logistics staff | Conduct live video call; ask to speak with production manager. |
Pro Tip: Factories often have “Factory” or “Manufacturing” in their Chinese name (e.g., 有限公司 – Co., Ltd. vs. 制造有限公司 – Manufacturing Co., Ltd.).
3. Red Flags to Avoid When Sourcing Cast Aluminum Mailboxes
| Red Flag | Risk | Recommended Action |
|---|---|---|
| Unrealistically Low Pricing | Indicates substandard alloy (e.g., recycled aluminum), thin walls, or hidden fees | Benchmark against market average (e.g., $12–$25/unit FOB for standard 300mm mailbox). Reject quotes >20% below average. |
| Refusal to Provide Factory Address or Audit Access | High likelihood of being a trading company or shell entity | Insist on third-party audit. Do not proceed without verifiable location. |
| Generic or Stock Photos | Misrepresentation of capabilities | Demand original, timestamped photos/videos of production line and molds. |
| No Mold Ownership or Design Rights | Risk of IP theft or production delays | Ensure contract includes mold ownership clause and design confidentiality. |
| Inconsistent Communication or Technical Gaps | Indicates intermediary role; poor quality control oversight | Require direct contact with engineering/QC team. Assess technical fluency in casting tolerances, alloy specs (e.g., A380, ADC12). |
| Pressure for Upfront Full Payment | Scam risk or financial instability | Use secure payment terms: 30% deposit, 70% against BL copy or post-inspection. |
| Lack of Compliance Documentation | Non-compliance with EU/US mailbox standards (e.g., ANSI, EN 13724) | Require test reports for corrosion resistance, impact strength, and UV stability. |
4. Recommended Due Diligence Checklist
✅ Verified business license with manufacturing scope
✅ Confirmed physical factory via audit or video tour
✅ Sample tested for material composition and durability
