This is a macro policy minefield. Although used cars are rarely classified as dumping, if your single import quantity is too large and the declared price is significantly lower than local similar products, it can easily trigger an investigation by the tax bureau. We strongly recommend B2B buyers to break down shipments into smaller batches and use multiple invoices for customs clearance.

We will use a megohmmeter (insulation resistance tester) to measure the insulation resistance of the high-voltage bus. If the resistance value is below the national safety standard, it indicates a risk of leakage, and the vehicle will be deemed unqualified.

Due to legal restrictions preventing unregistered vehicles from high-speed driving on public roads in China, most of our dynamic tests are conducted in a closed area (with a maximum speed of around 60 km/h). This is sufficient to test for suspension noise and low gear smoothness, but it cannot simulate high-speed wind noise and tire balance vibrations at 120 km/h.
