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.

Battery condition is the single biggest value factor in a used EV, and it can be measured — do not accept a verbal "battery is fine" without data. First, ask for a battery health certificate: brands like BYD, NIO, XPeng and Li Auto can generate an official state-of-health report from the VIN, usually within minutes at a dealer or via the brand's app. Look for SOH above 85% for a car under five years old. Second, request a charge-and-discharge test during inspection: the displayed range at 100% charge compared with the original rated range gives a practical health estimate. Third, check battery warranty status. Most Chinese brands offer 8 years or 150,000–200,000 km on the battery pack, and the remaining warranty usually transfers with the car — get this in writing. Fourth, for cars heading to hot climates, confirm the battery cooling system works; overheating is a common killer of battery life. Add a minimum SOH guarantee to your purchase contract so you have recourse if the battery underperforms.

Pure electric vehicles are classified as Class 9 Dangerous Goods due to their large lithium batteries, leading to strict shipping regulations. Shipping companies have high requirements for the loading position and fire isolation measures for dangerous goods, and some roll-on/roll-off ships refuse to accept used EVs. As a result, EVs often require more expensive special container shipping and incur additional handling fees for hazardous materials.
