We use an internationally certified electronic signature platform (such as DocuSign or Adobe Sign). Each signed contract generates a digital certificate with a timestamp and encrypted hash value, which has full legal defense effectiveness in international arbitration courts.

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.

Currently, in most developing countries, there is a severe lack of deep repair capabilities for the three electric systems. We recommend that B2B car dealers must have basic electrical insulation testing capabilities.
