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

Europe and some developed countries have very strict regulations on greenhouse gases. If required by customs, we will specify the exact refrigerant type and charge amount according to the vehicle's air conditioning compressor nameplate in the remarks section of the packing list and commercial invoice.
