This is one of the most common post-export surprises, so verify before buying. OTA updates: most Chinese brands push updates to cars registered on domestic servers. Many exported cars continue receiving updates normally, but some brands restrict updates by VIN region once the car leaves China. Ask the seller to confirm the update history and whether the brand officially supports your destination region. Some grey-import cars are stuck on the firmware version they left with. Companion apps: the factory app usually requires a Chinese phone number and a domestic account. After export, remote functions (preconditioning, charging status, location) often stop working or require workarounds. Some owners re-register via third-party services, but this is unofficial and can break at any time. Practical advice: before purchase, get the seller to show a screenshot of the car's current software version and connected services status. Factor in that you may lose remote features permanently, and check whether local dealers or independent shops can perform diagnostics and updates without the official app.

The standard set is: 1. Commercial invoice and sales contract - issued by the exporter; the basis for customs valuation. 2. Packing list - exporter; details the vehicle and any spare parts shipped with it. 3. Bill of lading - issued by the shipping line; your proof of ownership of the cargo. Never pay the full balance before receiving at least a copy of it. 4. Certificate of origin - issued by the China Council for the Promotion of International Trade (CCPIT); some countries require it for preferential duty rates. 5. Export customs declaration - Chinese customs; confirms the car was legally exported. 6. Pre-shipment inspection report - issued by companies like Intertek, SGS or the EAA scheme, if your country mandates it. Ask the exporter for scanned copies of all documents before shipping so you or your broker can verify completeness.

Timing your shipment can save both money and weeks of waiting. Several predictable patterns affect routes from China. Peak season surcharges: January through March, before Chinese New Year, exporters rush to ship, so container and RoRo space tightens and rates rise 20-50%. Book at least 3-4 weeks ahead during this window. After the holiday (usually February), factories and ports restart gradually, causing 2-3 weeks of backlog. Weather effects: Typhoon season (July-September) can delay departures from southern Chinese ports like Shenzhen and Guangzhou. Winter fog and ice affect northern ports like Dalian and Tianjin, slowing loading operations. Destination-side factors: Monsoon seasons can slow port operations in South and Southeast Asia. Holiday periods at destination (e.g., Ramadan in the Gulf, year-end holidays elsewhere) reduce customs staffing and extend clearance times. Practical advice: ask your forwarder for rate calendars, avoid booking right before major Chinese holidays, and build 1-2 weeks of buffer into delivery promises to your customers. Flexible departure ports (Shanghai vs. Ningbo vs. Shenzhen) can also help you find available space.
