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).

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.

Our responsibility ends with delivering the vehicle to the Russian border or Far East port and providing the legal Chinese export documents. The payment of Scrap Tax, application for SBKTS (Vehicle Structure Safety Certificate), and activation of the final e-PTS electronic passport must be fully handled by the Russian buyer and their local customs broker.
