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.

Water damage is one of the most common hidden problems in used cars, and it often escapes basic photo reviews. During a live video inspection, ask the inspector to check these specific points: 1. Smell test: A musty or moldy odor inside the cabin is the first red flag. Have them open all doors, run the AC briefly, and smell the air from the vents—musty AC often indicates water in the HVAC system. 2. Under the carpets: Lift the floor mats and look for water lines, rust stains, or dampness on the carpet backing and the metal floor underneath. Sediment or silt residue is a giveaway. 3. Seat rails and bolts: Pull the seats fully forward and backward. Rust on seat rails or fresh-looking bolts suggests the seats were removed for cleaning after flooding. 4. Trunk area: Check the spare tire well and under the trunk carpet for standing water marks or rust. 5. Electronics: Test every window, seat adjustment, and the infotainment screen—water-damaged electronics behave erratically. Also request a scan report: flood cars often store history codes for multiple control modules that failed simultaneously. Cross-check the car's origin; vehicles from flood-prone southern regions deserve extra scrutiny.

RoRo (roll-on/roll-off): the cheapest per car for running vehicles. Cars are driven onto the vessel and secured on decks. Transit to major ports (Jebel Ali, Rotterdam, Karachi) takes 15 to 35 days. Downside: cars are exposed to weather and salt air, and minor handling scratches happen occasionally. Container (20ft/40ft): one 40ft high-cube fits one car with parts, or two small cars with racking. Cost is higher than RoRo but cars are sealed and protected. Best for high-value vehicles, EVs (battery safety rules often require container), or when shipping spare parts together. Flat rack: for oversized vehicles (trucks, buses, modified cars). Priced per dimensions. Practical advice: for a standard used car to a port with RoRo service, choose RoRo and add marine insurance (0.3%–0.8% of value). If your destination lacks RoRo calls or you ship an EV, use a container. Always get the booking confirmation and bill of lading copy before paying the final balance.
