Absolutely prohibited. Chinese customs requires a "bare car" declaration for used car exports. If undeclared goods are found inside the vehicle, it could lead to inspection and detention, or even smuggling charges. We refuse any form of concealment requests.

A proper inspection relies on equipment, not just eyes. The inspector should use a paint thickness gauge to measure 50-60 points across body panels; original paint is typically 80-150 microns. An OBD diagnostic scanner reads stored and pending fault codes across all control units, and for EVs it also reads battery state of health and charge cycle counts. The car must go on a lift for the underbody check: frame rails, suspension components, oil leaks and accident repair marks are only visible from below. A battery tester checks starting voltage and charging system health, and a tread depth gauge documents tire condition. Ask for the report to include raw readings and dated photos rather than a simple pass/fail summary - that is what makes it verifiable.

If there is a minor leak in the lines due to bumps, it is possible that the cooling may not work upon arrival. This is a normal physical loss. The cost of vacuuming, pressure testing, and recharging refrigerant at a local auto repair shop is low and is the buyer's responsibility.
