Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.

Our documentation department has the latest versions of UN38.3 (United Nations Transport of Dangerous Goods Test and Standards) and MSDS reports authorized or filed by major Chinese new energy brands (such as BYD, Geely, GAC), which are essential customs documents for declaring dangerous goods to the maritime authority.

Chinese customs strictly prohibits the export of assembled or cut vehicles that meet mandatory scrapping standards. Since our pre-inspection is very strict, this situation is highly unlikely. However, if the vehicle is detained and returned by customs due to a policy misjudgment, we will fully refund your deposit without interest, ensuring you bear no policy risk.
