Typically you will need: 1. The commercial invoice and packing list from the seller; 2. The bill of lading issued by the shipping line; 3. The vehicle's export customs declaration; 4. The original registration certificate and a deregistration or transfer proof from China; 5. A certificate of origin if your country requires it; 6. Destination-specific documents, such as a pre-shipment inspection certificate (for example ECTN for West African ports). Requirements vary by country, so confirm the full list with your customs broker before shipment.

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.

The standard set is: 1. Commercial invoice and sales contract - issued by the exporter; the basis for customs valuation. 2. Packing list - exporter; details the vehicle and any spare parts shipped with it. 3. Bill of lading - issued by the shipping line; your proof of ownership of the cargo. Never pay the full balance before receiving at least a copy of it. 4. Certificate of origin - issued by the China Council for the Promotion of International Trade (CCPIT); some countries require it for preferential duty rates. 5. Export customs declaration - Chinese customs; confirms the car was legally exported. 6. Pre-shipment inspection report - issued by companies like Intertek, SGS or the EAA scheme, if your country mandates it. Ask the exporter for scanned copies of all documents before shipping so you or your broker can verify completeness.
