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.

All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

Two main shipping methods are used for used cars from China: 1) Container shipping: the car is loaded into a 20ft or 40ft container. Safer, protects from weather and damage, and allows personal items inside the car. Slightly more expensive. 2) RoRo (roll-on/roll-off): the car is driven onto the ship. Cheaper for single units, but no protection and no personal belongings allowed. Typical transit times from major Chinese ports (Shanghai, Guangzhou, Shenzhen, Qingdao): - Middle East: 12-20 days - Europe: 25-40 days - East/West Africa: 30-45 days - South America: 35-50 days - Southeast Asia: 5-12 days Add 5-10 days on each side for port handling, customs, and inland delivery. Peak season (before Chinese New Year and summer) can add delays, so book space 2-3 weeks ahead.
