Underbody scrape cases go wrong most often when version, subject, or point in time do not line up with each other. Handover material should include the underbody area, the loading ramp, and any leakage, and should name the party that supplied it, the person who confirmed it, and the confirmation time. A clean previous batch does not replace an independent check in this batch for load-bearing points that exterior photos miss. When the case is closed and filed, this cross-border vehicle procurement guide serves to check the before-and-after records. Re-verify against the underbody damage checklist after arrival at the port.
