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.

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).

We have established a database of target country policies. Check the specific requirements of the destination country in advance regarding vehicle age (left-hand/right-hand drive), emission standards (Euro 4/Euro 5), and steering position (left-hand/right-hand drive) to avoid customs clearance issues upon arrival.
