A typical payment structure looks like this: 1. Deposit: 10-30% after you confirm the car and price, often to reserve the vehicle and start the inspection. 2. Balance: paid after you approve the inspection report, but before or at shipment. A common safeguard is paying against a copy of the bill of lading, with telex release of the original B/L after funds arrive. 3. Never send 100% upfront to a new supplier. Use traceable methods (T/T bank transfer to a corporate account matching the company name, or escrow for first orders) and keep every agreement in writing. 4. Timeline: quote within days, inspection 3-7 days, booking and loading 1-2 weeks, ocean transit 3-6 weeks, customs clearance 3-10 days. Red flags: personal bank accounts, pressure to skip inspection, prices far below market.

Changes must be requested before the shipping cut-off date (SI Cut-off Date) prior to the vessel's departure. Once the vessel has sailed, the shipping company will charge a high amendment fee, which may also cause delays in customs clearance at the destination port, with costs borne by the buyer.

Use credit check apps (like Check Doctor or Ant Queen) to pull the complete accident record.
