Mixed fleet (operational + damaged)	Hybrid: RO-RO + Flat Rack	Segregate by condition; optimize cost and protection

---

4. Inland Logistics to San Antonio

All shipments debark at Port of Houston (Barbours Cut Terminal). Final delivery to San Antonio (190 miles NW) via:

• Drayage: Heavy-duty lowboy trailers (per TXDOT oversized load regulations)
• Transit Time: 1.5–2.5 days
• Cost: $1,300–$1,900 per truck (depending on weight and configuration)

Fleet managers are advised to coordinate just-in-time (JIT) delivery to minimize storage fees at destination yards.

---

5. Compliance & Documentation

Ensure all exports meet:
– Chinese Customs: Used Machinery Export License (Category B)
– U.S. EPA & DOT: Environmental and safety compliance for imported vehicles
