The customs of the destination country has the right to disregard the commercial invoice and reassess the value based on its internal database (such as the customs valuation red book). Any additional duties incurred are a result of the importing country's policy and are fully borne by the buyer (importer).

Both are common, and the right choice depends on budget and destination: 1. Container shipping (20ft/40ft): The car is sealed inside a container, offering better protection and allowing you to load spare parts inside the car. Typical cost from Shanghai to major world ports: $1,500-$3,000 per car. Best for long distances and high-value vehicles. 2. RoRo (roll-on/roll-off): The car is driven onto the ship and secured on deck. Cheaper ($800-$1,800 to most ports) and faster to load, but exposed to weather and port handling. Not all routes offer RoRo service. Transit time examples: to the Gulf 15-25 days, to West Africa 30-45 days, to Latin America 25-40 days, to Europe 20-35 days. Ask your exporter which option serves your destination port, and always insure the shipment for full value.

It's extremely difficult. Unauthorized modifications can lead to module current overload protection, resulting in a lock. In China, you need to use the factory online engineer account to reprogram it. It's basically impossible to perform online decoding overseas. We strongly warn against blindly modifying the electrical systems of modern integrated circuit vehicles.
