This is a macro policy minefield. Although used cars are rarely classified as dumping, if your single import quantity is too large and the declared price is significantly lower than local similar products, it can easily trigger an investigation by the tax bureau. We strongly recommend B2B buyers to break down shipments into smaller batches and use multiple invoices for customs clearance.

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.

RoRo (roll-on/roll-off): the cheapest per car for running vehicles. Cars are driven onto the vessel and secured on decks. Transit to major ports (Jebel Ali, Rotterdam, Karachi) takes 15 to 35 days. Downside: cars are exposed to weather and salt air, and minor handling scratches happen occasionally. Container (20ft/40ft): one 40ft high-cube fits one car with parts, or two small cars with racking. Cost is higher than RoRo but cars are sealed and protected. Best for high-value vehicles, EVs (battery safety rules often require container), or when shipping spare parts together. Flat rack: for oversized vehicles (trucks, buses, modified cars). Priced per dimensions. Practical advice: for a standard used car to a port with RoRo service, choose RoRo and add marine insurance (0.3%–0.8% of value). If your destination lacks RoRo calls or you ship an EV, use a container. Always get the booking confirmation and bill of lading copy before paying the final balance.
