It is difficult to debug this if you don't tell us how exactly you did
this encryption. Did you encrypt on the command line?
Run this for the encrypted file:
gpg --list-only --list-packets tmp.txt.gpg
You should get output like this:
:pubkey enc packet: version 3, algo 1, keyid 764311F281F06169
data: [2045 bits]
:encrypted data packet:
If it looks like this, run
gpg --list-keys 764311F281F06169
Is that the key of the recipient?

You may have made a public signature for the key which, of course, was
not part of the certificate you imported. Or the import file contains
signatures gpg ignores when importing (or at least when exporting):
Useless and old signatures (replaced by newer ones) may be ignored.

The same way:
gpg --list-packets import_file
gpg --list-packets export_file

May help to know the exact error message they get.
They may get a better error message if they try to decrypt in the
gpg -vvv your_file.gpg
