הלכה אויף במדבר 18:25

It is forbidden to move fruits that are forbidden to eat, such as fruits that have not been tithed—even if they are only obligated in [rabbinic] tithes—or first tithe the priestly tithe of which has not been taken, or impure tithes or second tithe and consecrated foods that have not been properly redeemed. But it is permissible to move demai, since it is fit for the poor; and likewise second tithe and consecrated foods that have have been redeemed—even though one did not [add the mandatory] fifth.
