Sea freight carries over 90% of China's car exports, but RORO and container shipping trade off cost, transit time and safety differently. The wrong choice can add 20% to your cost or trigger cargo-damage claims. This guide helps you match the mode to your route and volume.
1. Two Modes Compared
| Factor | RORO | Container |
|---|---|---|
| Loading | Cars driven aboard and parked | 2-4 cars per 40ft container |
| Cost | By CBM, cheaper at volume | Per box, flexible for small lots |
| Route coverage | Limited, main trunk routes | Nearly all major ports |
| Damage risk | Higher yard handling risk | Sealed box, better protection |
| Extras | Best for bulk vehicles | Can mix parts and personal items |
2. How to Choose
- Under 10 cars: Container first — flexible consolidation and wide port coverage; rail special boxes work for Central Asia.
- Bulk volumes: RORO has lower unit cost but depends on schedules and destination RORO capacity; book early in peak season.
- New energy vehicles: EVs must be declared under dangerous-goods rules; use carriers with EV credentials and prepare SOC documents.
3. Practical Points
- Lashing: Secure cars with straps and wooden wedges inside the box; photograph condition for evidence.
- Delivery state: Agree on fuel/battery level and tool list at handover to avoid port disputes.
- Buffer time: Red Sea diversions and peak congestion can add 2-3 weeks — pad the promised delivery date.
Shunwei Auto tip: Start with container LCL to test the market, then switch to RORO at volume. Compare "freight + destination charges + inland leg" as one total cost, not just the ocean rate.
Note: EV bookings need an MSDS and lithium-battery declaration; EV slots on hot routes sell out — book at least 3 weeks ahead.
