We will use a megohmmeter (insulation resistance tester) to measure the insulation resistance of the high-voltage bus. If the resistance value is below the national safety standard, it indicates a risk of leakage, and the vehicle will be deemed unqualified.

The standard process looks like this: 1. Selection: pick the car, request the VIN, registration certificate, and recent photos/videos. For higher-value cars, order an independent third-party inspection. 2. Negotiation and contract: agree on price and terms. Sign a written contract stating the car's condition, price, payment schedule, and delivery terms (FOB or CIF). 3. Deposit: typically 20-30% to reserve the car. Pay to the company's corporate account, never a personal one. 4. Verification: your agent or inspector confirms the car matches the contract before the balance is due. 5. Balance and export: pay the remaining amount; the seller arranges inland transport, export customs clearance, and port loading. 6. Shipping documents: you receive the commercial invoice, packing list, and bill of lading - usually by courier or email. 7. Arrival: your customs broker clears the car, you pay duties and taxes, then register it locally. Total timeline is usually 4-8 weeks depending on the shipping route.

Handling claims with an overseas exporter works best when expectations are set before payment. Prevention: put the inspection standard, photo/video evidence requirements, and a dispute clause into the sales contract. Keep all chat records and payment receipts. Typical process if issues arise: 1) Notify the exporter within 48-72 hours of delivery with photos/videos as evidence. 2) Most disputes fall into two buckets: shipping damage (handled via marine insurance — this is why insurance matters) or undisclosed mechanical defects (handled per contract, often via partial refund, spare parts, or repair cost sharing). Realistic expectations: exporters rarely accept returns, so negotiate compensation instead. A reputable company will usually cover reasonable repair costs for defects confirmed to pre-exist shipment. Tip: for higher-value cars, hire a local third-party inspection at destination as final evidence — it strengthens any claim significantly.
