Our documentation department has the latest versions of UN38.3 (United Nations Transport of Dangerous Goods Test and Standards) and MSDS reports authorized or filed by major Chinese new energy brands (such as BYD, Geely, GAC), which are essential customs documents for declaring dangerous goods to the maritime authority.

The technician will start the vehicle and turn on the air conditioning system, measuring the actual temperature at the vents at the lowest and highest settings with a thermometer; at the same time, they will connect a manifold pressure gauge to check if the refrigerant pressure in the high and low pressure lines is within the normal range, determining if there is a chronic refrigerant leak.

Our technical report will read the environmental information from the vehicle's factory-issued documentation (including certifications like National V, National VI, etc.). You need to submit the specific emission limit data we provide (such as grams of CO, THC, NOx emissions) to your country's environmental or customs authorities for compliance comparison.
