The current policy of CMFUid is that uids get deleted on import
(if you leave the "Remove the objects unique id on add (and import)" flag
in 'portal_uidannotation' checked).

Thus your code has to register the object a second time a unique id. 
This ensures that on imports no duplication happens.

I know it get's tricky if you want to import objects beeing related
if they rely on unique ids. But this is out of scope of CMFUid.
This is in scope of a hypothetical CMFRelation product managing that.

See 'portal_uidannotation' (UniqueIdAnnotationTool.py) for this.
