We will directly check the registration certificate (the big green book) and count the number of changes.

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 will provide extremely accurate production year, first registration date, and Chinese emission standards (e.g., National VI). However, the final responsibility for confirming whether this data complies with the importing country's regulations lies with the buyer, and you need to submit it to the local customs for verification before placing an order.
