Agreed that planetary wide disasters are rare. But, one has to remember on most worlds, they are sparsely populated. If the major urban centre(s) got hit with something and the week time delay would be part of the emergency planning.
I could see the Imperium via the Scout service sending emergency relief, if requested by the planetary government.
More often than not, I would see that Megacorporations would be the first ones on the ground trying to renegotiate trade deals in their favour by providing timely relief but at the cost of expanding their concessions. So, when the Scouts do finally arrive after about a month's delay - reconstruction aid from the Imperium would be viewed as minimal and only there for the most needy cases.
Some exceptions would naturally apply - for instance, if the world was of strategic importance or that there was an Imperial presence beyond the Starport - which would mean regular couriers could carry that information closer to a C&C hence aid could get there faster. But, again, the Imperium would dependent upon the Megacorporations to charter the items. Which the Megacorps would exact a price higher than just the financial.
