Cross-border after-sales support mainly comes from three channels: 1. Contract terms: Reputable exporters commit in the sales contract to engine and gearbox coverage for 30 days after pickup, excluding wear-and-tear items. Get this in writing before paying. 2. Inspection report: The pre-shipment inspection report is your baseline. If the car arrives with problems that contradict the report (e.g., hidden accident damage not disclosed), you can file a claim against it. 3. Parts supply: For mainstream Chinese brands, spare parts channels exist in Russia, Central Asia, the Gulf, and Africa. Many exporters will help you source and ship parts after delivery. Practical tips: inspect the car on arrival and photograph everything; report any issue in writing within 48 hours; keep all shipping documents. Claims filed weeks later are hard to prove.

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.

Start with the business license: every legitimate Chinese company has a Unified Social Credit Code. Ask for a copy and verify it on the National Enterprise Credit Information system or via your freight forwarder. Check that the business scope includes 'used car export'—this requires specific qualifications. Next, look for proof of substance: a real office or yard (verify via live video call, not pre-recorded), staff answering on Chinese business platforms like WeChat with consistent branding, and a corporate bank account in the company's name—never pay a personal account. Cross-check trade history: ask for recent shipping documents (blurred bills of lading with customer info hidden), references from buyers in your region, and whether they hold export licenses issued by Chinese commerce authorities. Red flags: prices far below market, pressure to pay quickly, refusal of video calls, or bank accounts in third countries 'for convenience'. Take your time—real exporters pass these checks easily.
