Process plants are expensive to stop and slow to restart, so an instrumentation part or a control component moves on the same logic as a line-down machine spare. The sample traffic is different: quality, arbitration and pre-shipment samples all decide whether a cargo moves at all, and they decide it on a clock.
01This is the sector where the answer is most often a qualified no. A great many chemical samples are dangerous goods, and dangerous goods in a passenger cabin are governed by rules that do not bend for urgency.
02Where the material can travel, the classification, the packing instruction and the documentation have to be right and prepared by someone trained and certified to prepare them.
