Fog, then the port haul
Cooler winters still leave fog on cold metal. A crate that sits uncovered overnight sweats. Whether a sealed barrier belongs in the pack depends on pad time and whether the cargo will wait at Hai Phong. The survey records season and dwell.
Bac Ninh electronics need a clean wrap before timber so park dust does not travel with the rack. Thai Nguyen process plant may still hold fluids; draining is a plant decision recorded on survey. The two classes should not share an unsealed crate.
Road to Hai Phong is short but wet. Shock blocking is still required. Where regulated solid-wood packaging is used for an international shipment, treatment and marking are specified to the destination's applicable ISPM-15 requirements. Processed-wood materials such as plywood may be exempt, subject to the destination rules and customer specification.
Bac Ninh winter nights drop below the dew point on cold cabinets. An uncovered crate on the pad is a condensate job even when Hai Phong is close.
Thai Nguyen process frames and Bac Ninh racks in one movement still need a split pack. Fluid status on the frames is a plant decision recorded before wrap.
