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.

4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.

This is a macro policy minefield. Although used cars are rarely classified as dumping, if your single import quantity is too large and the declared price is significantly lower than local similar products, it can easily trigger an investigation by the tax bureau. We strongly recommend B2B buyers to break down shipments into smaller batches and use multiple invoices for customs clearance.
