We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats.

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.
