For those keeping score at home, I've received a couple of different options to resolve this issue:

First: Using Norm's advice below I copied the export file into ASM and performed the import. It ran, but I couldn't get the logfile to write so got around that this way:

ASMCMD> cd data
ASMCMD> mkdir exports
ASMCMD> cp /mnt/mydir/myfile.dmp +data/exports

SQL> Create directory backups as 'exports'

This created a directory backups pointing to +DATA/exports

The import failed with an inability to write the logfile.

Got around that by using one of the Oracle defined direcories instead for the logfile:

Impdp directory=backups dumpfile=myfile.dmp logfile=ORACLE_BASE:myfile_imp.log

Second: I had also raised an SR with Oracle Support

This also appears to work:

Login to CDB:

alter session set "_oracle_script"=TRUE; alter session set container = cdb$root; create or replace directory backups sharing=metadata as '/tmp'; alter session set container = ellprd9;
create or replace directory backups sharing=metadata as 'tmp';

I haven't completely tested that one yet, but the directory DID create correctly in the PDB..

Thanks also to Sayan for responding, I've filed your solution away for later testing, I had such a problem getting the encryption wallets set up for these PDB's that the unplug and replug was an option of last resort here 😊

Thanks again for the replies.

Have you looked at the "cp" command in the asmcmd utility? That allows files to be copied into and out of ASm, apparently.

Other, possible, options are the procedure DBMS_FILE_TRANSFER.COPY_FILE but that appears to only allow database files to be copied into AMD. :(

HTH Cheers,
