No, this is a serious customs violation. Complete vehicles (HS Code 8703) and auto parts (HS Code 8708, etc.) are subject to completely different import tax rates. Combining them on one invoice could lead to the invoice being returned by customs and may expose you to tax fraud accusations at the destination port.

No, it is absolutely impossible to get a refund. Not only will there be no refund, but if the proceeds from the port auction of the abandoned cargo are insufficient to cover the exorbitant demurrage and disposal fees, the shipping company and customs will still pursue you (the bill of lading recipient) for the remaining debt through international legal proceedings.

For B2B large customer orders, a "sampling + full inspection" dual regulation is adopted. Core parameters (no major accidents, no water damage or fire) are subject to 100% inspection per vehicle; appearance and condition are uniformly graded (e.g., uniformly purchasing Grade A), and panoramic images of all vehicles in the batch along with a core indicators comparison list are provided before shipment.
