It's not mandatory. Four-wheel alignment and dynamic balance are part of routine maintenance. During long-distance towing and sea transport, the suspension may experience slight changes in stress. We recommend that buyers perform a four-wheel alignment locally after picking up the vehicle at the destination port and replacing tires suitable for local road conditions.

RoRo (roll-on/roll-off): the cheapest per car for running vehicles. Cars are driven onto the vessel and secured on decks. Transit to major ports (Jebel Ali, Rotterdam, Karachi) takes 15 to 35 days. Downside: cars are exposed to weather and salt air, and minor handling scratches happen occasionally. Container (20ft/40ft): one 40ft high-cube fits one car with parts, or two small cars with racking. Cost is higher than RoRo but cars are sealed and protected. Best for high-value vehicles, EVs (battery safety rules often require container), or when shipping spare parts together. Flat rack: for oversized vehicles (trucks, buses, modified cars). Priced per dimensions. Practical advice: for a standard used car to a port with RoRo service, choose RoRo and add marine insurance (0.3%–0.8% of value). If your destination lacks RoRo calls or you ship an EV, use a container. Always get the booking confirmation and bill of lading copy before paying the final balance.

Due to legal restrictions preventing unregistered vehicles from high-speed driving on public roads in China, most of our dynamic tests are conducted in a closed area (with a maximum speed of around 60 km/h). This is sufficient to test for suspension noise and low gear smoothness, but it cannot simulate high-speed wind noise and tire balance vibrations at 120 km/h.
