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 can only infer from the existing connected maintenance records. If the records show continuity and adhere to the recommended maintenance schedule, we will assign a high credit score; if there are gaps of tens of thousands of kilometers, we will assume it was not well maintained during that period and alert you.

Demurrage is a penalty charged by the port or shipping company for not clearing and picking up goods on time after they arrive. To avoid it: send customs documents in advance and ensure the recipient is prepared with duties and import qualifications.
