Air suspension is very delicate. If, after the vehicle has been stationary for about 12 hours, the height on one side of the vehicle drops more than 1.5 cm when measured from the wheel arch to the tire, we will determine that there is a slight air leak in the air spring or distribution valve on that side and warn you of the high subsequent repair costs.

It does not affect basic driving and regular speed cruise, but it will trigger a fault alert for advanced driver assistance on the dashboard. The LiDAR assembly is extremely expensive, so we focus on checking the integrity of the glass cover with a strong flashlight during inspections.

A compliant shipment from China includes a standard document set. Verify you receive all of them before the ship departs, because correcting documents mid-transit is slow and expensive. The core set: commercial invoice, bill of lading (original, if your country requires presentation for customs), packing list, certificate of origin, and the export customs declaration. For used cars, also expect the Chinese registration certificate copy, deregistration proof, and a condition/inspection report. Some destinations require additional certificates — GCC states need GSO conformity, EU countries need COC or individual approval, several African nations require BESC/ECTN tracking numbers issued before loading. Your customs broker will typically need the invoice and bill of lading at minimum, plus proof of vehicle age and emissions where age limits apply. Ask your exporter for scanned copies the day the vessel sails, not when it arrives: pre-clearance can cut port storage fees significantly. One caution: the invoice value must match your payment records. Under-declaring to save duties is customs fraud in most countries and risks seizure.
