SOH (State of Health) measures the battery's remaining capacity as a percentage of its original capacity. Two EVs with the same mileage can have very different SOH depending on charging habits and climate exposure, and since the battery represents 30-50% of a used EV's value, the SOH number is effectively the real price tag. A proper certificate includes current SOH percentage, cell voltage balance, charge cycle counts, battery management system fault codes, and often a projected range estimate. In hot-climate markets like the Gulf, a degraded battery degrades even faster, so a documented SOH above 85-90% is strongly recommended. Exporters who provide verified SOH certificates close deals faster and command better prices, so treat the certificate as a core purchase document, not an extra.

China does not have a single public accident database like CARFAX, but you can still verify history from several sources. First, ask the exporter for the insurance claim records (出险记录). Major repairs go through insurance, and the claim history shows the date, amount, and damaged parts. A car with large claim amounts (over half its value) is effectively a total loss rebuild. Second, check the vehicle's registration certificate (机动车登记证书) for transfer history — multiple transfers in a short period often follow an accident. Third, run a VIN check through commercial platforms (paid, around 20-50 RMB) which aggregate insurance, maintenance, and auction data. Cross-check everything against a physical inspection: paint thickness readings on structural points, weld quality under the seals, and underbody photos. If the records and the physical condition do not match, walk away or demand a large discount.

Once the car is loaded, the exporter (or freight forwarder) should send you a booking confirmation and, after departure, the Bill of Lading (B/L). The B/L is the key document: it shows the shipper, consignee, vessel, ports, and usually the VIN and container number. You can track the vessel on the shipping line's website using the B/L number or container number, or through third-party trackers like MarineTraffic. As the shipment approaches, the agent at destination issues an Arrival Notice. To collect the car you will typically need the original B/L (or a telex release/e-release), the arrival notice, your ID, and customs clearance paperwork. Check the B/L carefully as soon as you receive it—VIN, container number, and your name must be exactly right, because correcting a B/L mid-voyage is slow and expensive.
