The vehicle must meet the emission standards of the destination country (e.g., Euro IV, V, or VI). Ensure the bus complies with passenger safety regulations, including functional seatbelts for all seats, emergency exits, and fire extinguishers. For specific markets, check for ROPS (Roll-Over Protective Structure) certification if the bus will be used in mining or extreme off-road environments. Always verify that the VIN (Vehicle Identification Number) is clear and matches all documentation to avoid customs seizure.
