For B2B large customer orders, a "sampling + full inspection" dual regulation is adopted. Core parameters (no major accidents, no water damage or fire) are subject to 100% inspection per vehicle; appearance and condition are uniformly graded (e.g., uniformly purchasing Grade A), and panoramic images of all vehicles in the batch along with a core indicators comparison list are provided before shipment.
Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.
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.
