From a technical perspective, China's "National VI B (China VI-b)" is one of the strictest emission standards globally, with limits on carbon monoxide, nitrogen oxides, and particulate matter that are even stricter than some of Europe's Euro VI standards. However, the two are not legally recognized by each other, depending on your country's import regulations.

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.

We thoroughly rule them out by checking if the cabin wiring harness is melted, if the seat belts have water stains or mold, if there is unusual rust or debris in the seat tracks and cigarette lighter, and by verifying with the insurance company for any "total loss claims." These two types of cars are an absolute sales ban for us.
