RoRo ships usually charge based on the vehicle's volume (length x width x height, calculated in CBM) in tiers; container shipping has a fixed compartment price. We will calculate which method is the most economical for the current sailing.

Pure electric vehicles are classified as Class 9 Dangerous Goods due to their large lithium batteries, leading to strict shipping regulations. Shipping companies have high requirements for the loading position and fire isolation measures for dangerous goods, and some roll-on/roll-off ships refuse to accept used EVs. As a result, EVs often require more expensive special container shipping and incur additional handling fees for hazardous materials.

Changes must be requested before the shipping cut-off date (SI Cut-off Date) prior to the vessel's departure. Once the vessel has sailed, the shipping company will charge a high amendment fee, which may also cause delays in customs clearance at the destination port, with costs borne by the buyer.
