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.

Two main shipping methods are used for used cars from China: 1) Container shipping: the car is loaded into a 20ft or 40ft container. Safer, protects from weather and damage, and allows personal items inside the car. Slightly more expensive. 2) RoRo (roll-on/roll-off): the car is driven onto the ship. Cheaper for single units, but no protection and no personal belongings allowed. Typical transit times from major Chinese ports (Shanghai, Guangzhou, Shenzhen, Qingdao): - Middle East: 12-20 days - Europe: 25-40 days - East/West Africa: 30-45 days - South America: 35-50 days - Southeast Asia: 5-12 days Add 5-10 days on each side for port handling, customs, and inland delivery. Peak season (before Chinese New Year and summer) can add delays, so book space 2-3 weeks ahead.

From a technical perspective, China's "National VI B (China VI-b)" is one of the strictest emission standards globally, with limits on carbon monoxide, nitrogen oxides, and particulate matter that are even stricter than some of Europe's Euro VI standards. However, the two are not legally recognized by each other, depending on your country's import regulations.
