Foreign delivery ignoring old and established practice (9)
I believe the answer is:
tradition
'established practice' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for tradition that I've seen before include "Custom passed on" , "Custom, long-standing practice" , "customary behaviour" , "Established custom" , "Long-established custom or belief" .)
