As rubber seals age, "slight oil seepage (oil stains but no dripping)" is very common in used cars and is not considered a major fault. Our recommendation is: as long as the oil level does not drop abnormally, just clean and monitor it regularly after arrival, without the need to immediately incur high costs to disassemble and replace the seals.

Ask the exporter for a paint thickness gauge report, or request a live video where they measure the car in front of you. What to look for: · Factory paint on most Chinese cars measures 80–120 microns. Readings above 150–200 microns on a panel usually mean repainting; above 300 microns often means body filler (putty) underneath. · Inconsistent readings between panels (e.g., left door 95µm, right door 180µm) suggest the right side was repaired. · Check gaps between panels (doors, hood, trunk). Uneven gaps or misaligned headlights/bumper clips point to past collision repairs. · Look for overspray on rubber seals, plastic trim, or inside door jambs — a clear sign of repainting. · Check bolt heads on fenders, doors, and hood. Wrench marks or fresh paint over bolts mean the panel was removed. Combine these checks with an OBD scan for airbag or crash-related fault codes. Any repainting should be declared by the seller; if discovered undeclared, you have grounds to renegotiate or reject the car.

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.
