This is considered a force majeure risk. We will require the vehicle's state of charge (SOC) to be maintained in a safe dormant range of 30%-50% before loading, and we will insure you for all marine risks under CIF terms. If the battery suffers thermal runaway total loss due to abnormal cargo hold temperatures, the insurance company will compensate.

A Chinese history report (查博士, 精真估, or 4S-shop records) usually contains several sections. Here's how to read them. Accident records: entries tagged 重大事故 (major accident) or listings at an insurance payout above 30% of the car's value are serious red flags. Airbag deployment is a deal-breaker for most buyers. Mileage timeline: check that mileage increases logically between service visits. A sudden drop between two dates means odometer tampering—walk away. Ownership count: more than 3 owners in 5 years suggests a problem car. Also check the 使用性质 field: a car registered as 营运 (commercial/taxi use) has a much shorter legal lifespan. Maintenance entries: consistent 4S dealership records are a good sign; long gaps aren't necessarily fatal if the owner used independent shops, but ask for receipts. Cross-check the report against the VIN plate, registration certificate, and physical inspection. If the report shows no accidents but paint thickness readings say otherwise, trust the metal, not the paper.

For gasoline cars, insist on a compression test: each cylinder should read within 10-15% of the others, and the actual values should match factory specs for that engine. A single low cylinder points to worn rings or valve problems that idle checks will never reveal. A leak-down test goes further. It pressurizes each cylinder and measures how much air escapes and where. Air hissing from the oil filler cap means ring wear; from the intake or exhaust means valve issues; bubbles in the radiator coolant mean a head gasket problem. This is the single most revealing test for engine condition. Also request OBD scan data with freeze-frame records, a coolant system pressure test (to catch hidden leaks), and an inspection of the timing belt or chain condition with service history. For electric vehicles, compression tests don't apply — instead ask for a battery health report from the BMS, motor insulation readings, and a road test logging any inverter or drive-unit fault codes. A written report with photos or video of each test is essential evidence for your records.
