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.

It will cause serious obstacles. China's foreign exchange controls are extremely strict. If the remittance note and the remitter do not match our declared contract, the bank will reject the transaction (Pending). We will need to spend several days submitting additional explanations to the foreign exchange authority, which will inevitably delay the shipping schedule.

Absolutely not. Any secondary damage caused by overseas non-professional repairs, violent disassembly, or the use of inferior replacement fluids will immediately void any form of "extended parts compensation" we provide.
