1. Verify Legal & Export Compliance (Non-Negotiable)

Must-have documents

• Business License (with “vehicles manufacturing/export” scope)
• MIIT Approval (listed in China’s vehicle production 公告 —legitimate factory only)
• CCC Certification (compulsory for export)
• Export License + Customs Registration (proves export authority)
• ISO 9001 (quality management)
• No legal disputes (check via national enterprise credit system)

Red flags

• No factory—only a trading company without production rights.
• Cannot provide original CCC/MIIT docs (copies only).
• Registered <2 years, or frequent name changes.

2. Check Factory Scale & Manufacturing Strength

Key indicators

• Production history: ≥5 years in semi-trailer manufacturing.
• Workshop size: ≥20,000 m², robot welding lines + sandblasting + automatic painting.
• Annual output: ≥3,000 units (proves stable supply chain).
• Core equipment: CNC cutting, hydraulic test benches, 3rd-party inspection station.
• Staff: ≥50 technical workers + dedicated QC team.

Top reliable regions/brands

• Liangshan cluster: CIMC, Luoxiang, Tonghua, Foshan (large-scale, export-focused).
• National brands: CIMC (global), Shacman, HOWO (truck + trailer matching).

Red flags

• Small workshop with manual welding (poor consistency).
• No sandblasting/painting line (rust risk for Africa’s humid climate).

3. Audit Quality Control & Africa-Adapted Build

Critical quality checks (ask for photos/videos)

• Frame material: Q345B high-strength steel (16Mn) – no cheap Q235.
• Welding: Full penetration, no pores, robot welds preferred.
• Suspension: Heavy-duty leaf springs (avoid air suspension for Africa) + reinforced axles (Fuwa/BPW copy or genuine).
• Brakes: Wabco or equivalent air brakes + emergency brake system.
• Tires: 12R22.5/315/70R22.5 heavy-duty radial (brand: Triangle, Double Star).
• Painting: Sandblasting + epoxy primer + 2-layer topcoat (anti-rust for coastal Africa).

Africa must-have specs

• Reinforced chassis (thicker main beam, 300mm+ width).
• Extra cross supports (for overloading common in Africa).
• Simple electrical system (less electronics = fewer breakdowns).
• Spare tire bracket + toolbox (standard).

Red flags

• “Lightweight only” (too weak for African roads).
• No load test report or QC checklist.
• Using Q235 steel (thin, easy to crack).

4. Evaluate Export Experience & Africa References

Verify these

• Years exporting to Africa: ≥3 years (Nigeria, Kenya, Ghana, Tanzania top markets).
• African client references: Ask for 3–5 contactable buyers (call/WhatsApp verify).
• English capability: Sales + technical support fluent in English.
• Export volume: ≥500 trailers/year to Africa.
• Packing: Sea-worthy export packing (rust-proof film, wooden skids).

Red flags

• “First time to Africa” (no logistics/customs experience).
• No African references or refuses to share.
• Poor English communication (misunderstandings = delays).

5. Confirm After-Sales & Parts Supply (Africa Critical)

Must-ask questions

• Warranty: 12 months (frame/axles) minimum; 6 months for wear parts.
• Parts stock: Do they stock Fuwa axles, brake shoes, leaf springs, tires in China warehouse?
• Parts shipping: Can they send parts to Africa in 5–7 days via sea/air?
• Technical support: 24/7 WhatsApp/Zoom support (English-speaking mechanics).
• Local agents: Any service partners in your African country?

Red flags

• “No warranty” or “Warranty only in China.”
• No parts stock—“we can order” (too slow for Africa).
• No English technical support.
