Before shipping you should hold: the sales contract and commercial invoice, the export declaration (customs form showing the VIN), the vehicle registration certificate, and the bill of lading or rail waybill once cargo is loaded. Verify them like this. The VIN on the invoice, the export declaration, and the waybill must be identical, character for character. The registration certificate should show a clear ownership chain with the seller as the current owner; ask for a scan before payment. The export declaration proves the car legally left China and is essential for customs clearance at destination. If the exporter cannot provide the registration certificate or hesitates on the VIN check, pause the deal. Also confirm who handles the document courier: originals should arrive before or with the vessel, because many ports will not release a car without original bills of lading.

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.

State of Health (SOH) tells you how much of the original battery capacity remains. Here's how to use it. Reading the report: SOH is usually shown as a percentage of original capacity. A car at 90% SOH retains roughly 90% of its original range. Also check for cell imbalance (voltage spread between modules)—a low SOH with balanced cells is often fine, but high imbalance causes sudden range drops and charging problems. Acceptable thresholds: for a car under 3 years old, expect 90%+ SOH. For 3-5 years, 85-90% is normal. Below 80% SOH, the battery may soon need replacement—replacement costs can exceed the car's value, so negotiate hard or walk away. How to verify: don't trust a screenshot. Ask for a live screen recording of the diagnostic app (like the brand's official tool) starting from the car's VIN page. Cross-check the fast-charging curve: a healthy battery charges at near-peak rate up to 60-70%; a degraded one tapers early. Finally, remember that hot climates degrade batteries faster—if the car spent its life in southern China, scrutinize SOH more carefully.
