All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

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.

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.
