This is one of the most common disappointments after importing a Chinese EV, so check before you buy. Many Chinese EVs rely on an embedded SIM that only works on Chinese carrier networks. Once the car leaves China, remote functions — battery status, pre-conditioning, charging control, and locating the car — may stop working entirely. Some brands let you transfer the account to a foreign phone number, but many require a Chinese ID or Chinese phone number for registration, which you cannot provide. What to do before purchase: ask the exporter to test the app functions live on video while the car is still in China, including remote air-conditioning and battery percentage reading. Ask the brand's official customer service (in writing) whether overseas account activation is supported for your specific model and year. Workarounds if the official app does not work: some functions may still operate locally through the car's own settings, such as scheduled charging from the dashboard. Third-party OBD dongles with companion apps can sometimes restore battery monitoring and pre-conditioning. The car itself drives fine without connected services, but if app functionality matters to you, treat it as a purchase criterion, not an afterthought.

Rust is one of the most underestimated problems in remote buying. Request specific evidence: photos of the underbody, wheel arches, door sills, and around the windshield seal; close-ups of suspension mounting points; and ideally paint thickness readings across panels (factory paint is typically 80-120μm; heavy patches suggest bodywork). Northern Chinese cars may have winter road-salt corrosion; coastal cars can show surface rust on exposed metal. Surface rust on exhaust and bolts is normal—structural rust on frame rails, subframes, or brake lines is a deal-breaker, especially if the car is headed to a humid or coastal market. Have the inspector tap suspicious areas during the video call: flaky or bubbling metal sounds hollow. Walk away if the seller refuses underbody photos.

Used cars are classified under HS heading 8703 (motor vehicles for transport of persons), with the last four digits determined by engine type and size. Gasoline cars usually fall in 8703.21–8703.80 depending on displacement; pure EVs fall under 8703.80; hybrids have their own subheadings. The duty amount depends on your country's tariff schedule: 1. Most countries charge duty on the CIF value (car price + freight + insurance), not the FOB price. 2. Many developing markets levy higher duties on used vehicles than new ones, and some add a surcharge based on age — older cars can cost significantly more to clear. 3. After duty, you typically pay VAT/GST on the CIF + duty total, plus port and customs fees. Practical tips: ask your exporter to state the exact HS code on the commercial invoice and confirm it with a local customs broker before shipping. A wrong code can trigger reclassification, penalties, or delays. Also budget for any excise tax tied to engine capacity — in several markets a 2.5L car clears far cheaper than a 3.5L one.
