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.

To ensure the legal rights of both parties, the "International Used Car Sales Contract" we signed is in both Chinese and English. Generally, the contract is governed by Chinese law. All liabilities for breach of contract and force majeure clauses will be clearly defined in the contract.

A typical payment structure looks like this: 1. Deposit: 10-30% after you confirm the car and price, often to reserve the vehicle and start the inspection. 2. Balance: paid after you approve the inspection report, but before or at shipment. A common safeguard is paying against a copy of the bill of lading, with telex release of the original B/L after funds arrive. 3. Never send 100% upfront to a new supplier. Use traceable methods (T/T bank transfer to a corporate account matching the company name, or escrow for first orders) and keep every agreement in writing. 4. Timeline: quote within days, inspection 3-7 days, booking and loading 1-2 weeks, ocean transit 3-6 weeks, customs clearance 3-10 days. Red flags: personal bank accounts, pressure to skip inspection, prices far below market.
