Adrian,

   what imp tries to do is recreate the object in the same tablespace as it originates from, and if this fails (because the tablespace doesn't exist or the target schema is not allowed to create segments in it) then it falls back on the default tablespace. Check that your target user HAS NOT the UNLIMITED TABLESPACE privilege, and play on quotas (setting them, even temporarily, to 0, when you do not want something to land somewhere) to direct segment creation where you want it to happen. It would be easy if you only had tables, but the presence of indexes, partitions or LOBs as in your case makes it a little difficult to play with when you want to totally relocate everything. It may be simpler to reimport under a different user but in the same tablespaces and then MOVE objects.
