Document the high-humidity protection first. The handover material should cover connector sealing, drainage paths, and the storage environment, and should name the provider, the person who confirmed it, and the confirmation time. A clean previous batch does not replace an independent check for this batch on whether inland pilot-vehicle experience carries over to a coastal market. For the full evidence scope on high-humidity protection, see this vehicle-import FAQ. The automotive product researcher should state the reasoning in the high-humidity risk list rather than forwarding the supplier's account.
