Well, you shouldn't have to, because the requirement is that the SCCR has to be at or above the AFC, so that's a given...
Hopefully though, your specs clearly spell out that any packaged mechanical equipment and control panels shall have the proper SCCR to meet that. That's something that happens a LOT lately; low bidder packaged equipment suppliers pay no attention to it and use cheap control panels that come with the "courtesy" untested/unlisted 5kA SCCR, then expect the poor EC to come up with a way to connect it... That issue HAS TO BE dealt with in the specifications or procurement requirements.
