The customs of the destination country has the right to disregard the commercial invoice and reassess the value based on its internal database (such as the customs valuation red book). Any additional duties incurred are a result of the importing country's policy and are fully borne by the buyer (importer).

1) Verify the company: business license, export track record, and a live video call where they show the actual car and its VIN. 2) Hire an independent pre-shipment inspection. 3) Sign a contract stating the VIN, specs, price, Incoterm, and refund conditions. 4) Pay a 20–30% deposit by bank transfer only after the contract is signed — never the full amount, and never to a personal account. 5) After the inspection passes, pay the balance against a copy of the bill of lading. 6) Track the shipment and prepare import documents. 7) Inspect the car on arrival before releasing any final documents. Each step is a checkpoint. Don't let the seller rush you past one.

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.
