EXECUTIVE OVERVIEW: USED TRUCKS IN SAN ANTONIO, TEXAS
Prepared for Fleet Managers & Construction Operations Leadership

---

Strategic Relevance of San Antonio as a Sourcing Hub

San Antonio serves as a critical logistics nexus for heavy truck deployment across North American mining, construction, and bulk logistics sectors. Its geographic position—anchored by I-35, I-10, and proximity to Mexican border crossings—enables efficient access to active shale extraction sites (Eagle Ford), aggregate quarries, and interstate freight corridors. The local used truck market is characterized by high availability of refurbished 6×4/8×4 rigid dump trucks and 6×2 tractor units (primarily SINOTRUK HOWO, SHACMAN F3000, XCMG XG90 series), which have undergone documented operational cycles in comparable heavy-duty environments. These units exhibit proven resilience under:
– Mining: 15-25 ton payload cycles on unpaved haul roads (e.g., limestone quarries in Central Texas)
– Construction: 10,000+ hour service life in asphalt/concrete delivery with frequent stop-start cycles
– Logistics: >500,000-mile durability on interstate routes with consistent 80,000 lb GVWR compliance

SEA LION International’s 18-year export specialization ensures these assets undergo ISO 9001-aligned refurbishment, including engine/transmission rebuilds to OEM tolerances, structural integrity verification (per SAE J2247), and replacement of safety-critical components using genuine spare parts. This mitigates downtime risks inherent in unvetted secondary markets.

---

2. Corrosion Protection: Wax Spraying Treatment

Marine environments expose metal surfaces to salt-laden air and condensation, significantly increasing the risk of corrosion during transit (average humidity: 75–90%, salinity: 3.5%). To mitigate degradation of chassis, undercarriages, and engine components, wax-based anti-corrosion spraying is recommended for all export shipments.

Wax Spraying Specifications:

Parameter	Specification
Product Type	Solvent-based synthetic wax (e.g., Dinitrol 4880, Fluid Film)
Application Method	High-pressure spray (minimum 25 psi)
Coverage Areas	Frame rails, suspension, brake lines, wheel hubs, undercarriage
Film Thickness	20–30 microns (dry)
Curing Time	24–48 hours pre-shipment
Service Life	Up to 12 months (marine exposure)
Compliance	Meets ISO 9227 (salt spray resistance)

Note: Wax treatment is mandatory for all non-RO-RO methods due to extended exposure during loading/unloading. RO-RO units benefit from faster turnaround but still require undercarriage protection.

---

3. Recommended Logistics Pathway

Optimal Route:

Origin: Qingdao Port, China
Ocean Leg: Flat Rack Container → Houston, TX (via COSCO/ONE services)
Inland Leg: Rail (Union Pacific) → San Antonio Intermodal Terminal
Final Delivery: Local trucking (≤ 50 miles)

Rationale:

• Flat Rack ensures maximum protection for used trucks, especially non-operational units common in secondary markets.
• Containerization simplifies customs, reduces theft risk, and enables seamless intermodal transfer.
• Wax spraying applied pre-loading at origin yard (Qingdao) ensures corrosion resistance over 30+ day transit.
• Total Landed Cost (per truck): ~$4,300 (inclusive of wax treatment, lashing, insurance, and inland transport).

---

4. Risk Mitigation Protocol

Risk Factor	Mitigation Measure
Saltwater Corrosion	Full undercarriage wax spray; desiccant packs in cabs
Lashing Failure	ISO-compliant lashing points; 8-point tie-down system
Port Delays (U.S. Gulf)	Pre-clearance via AMS; bonded carrier agreements
Theft/Vandalism	Sealed containers; GPS-tracked units
Weather Exposure (RO-RO)	Avoid monsoon season (May–Sept); use deck covers

---

5. Conclusion & Recommendation

For fleet managers and construction firms importing used trucks from China to San Antonio, Flat Rack shipping with wax-based corrosion protection is the optimal solution for balancing cargo integrity, security, and long-term equipment reliability. While RO-RO offers faster turnaround for operational units, its exposure risks and limited flexibility make it less suitable for mixed-condition fleets. Bulk cargo, though economical, presents unacceptable damage and corrosion risks without extensive post-arrival refurbishment.

Final Recommendation:
Adopt Flat Rack + Wax Spraying as standard protocol for all used truck exports from China. Partner with certified logistics providers offering integrated ocean-rail solutions from Qingdao to San Antonio, with full condition reporting pre- and post-transit.
