SOH (State of Health) measures the battery's remaining capacity as a percentage of its original capacity. Two EVs with the same mileage can have very different SOH depending on charging habits and climate exposure, and since the battery represents 30-50% of a used EV's value, the SOH number is effectively the real price tag. A proper certificate includes current SOH percentage, cell voltage balance, charge cycle counts, battery management system fault codes, and often a projected range estimate. In hot-climate markets like the Gulf, a degraded battery degrades even faster, so a documented SOH above 85-90% is strongly recommended. Exporters who provide verified SOH certificates close deals faster and command better prices, so treat the certificate as a core purchase document, not an extra.

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.

The commercial invoice and export license we provide are based on the vehicle's underlying VIN and official Chinese nameplate data. If there are minor discrepancies with the destination country's customs system parameters (such as curb weight), we will issue a "Parameter Explanation Letter" stamped by our company to assist you in explaining, but we cannot change the official document data.
