Hello David,
from your post I got the impression that this is somehow related to legal control/license checks.
Have you thought about customer-specific+material-specific licenses - as in foreign trade?
Listings/exclusions do not handle very well changes to validity periods, so if I were you, I would try to avoid them in your scenario - even if I could get them to work somehow only for ship-to-parties.
In standard listing/exclusion use sold-to and payer, if I remember correctly.
