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.

Ask the exporter for a copy of the vehicle registration certificate (机动车登记证书). It lists every owner change and any mortgage registration. If the car was financed, there will be a lien entry; make sure a release entry follows it. You can also verify the VIN against public records through the traffic management platform (12123) — a legitimate exporter can generate a status report on the spot. Check that the seller's company name on the invoice matches the registered owner. For extra safety, require a written statement that the vehicle is free of liens, loans, court seizures, and lease agreements, and wire payment only to the company's corporate account after ownership is transferred to the export entity. That sequence — transfer first, payment second — is your strongest protection.

We mainly collaborate with professional organizations certified by China's national CMA (Certification of Inspection and Testing Institutions). If you need the highest level of international endorsement, we can arrange for independent inspection agencies like SGS or TÜV to conduct Pre-Shipment Inspections (PSI) before loading at the port.
