Bans amber production and leaves (9)
I believe the answer is:
embargoes
'bans' is the definition.
(I've seen this before)
'amber production and leaves' is the wordplay.
'production' indicates anagramming the letters.
'and' means one lot of letters go next to another.
'leaves' becomes 'goes' (I've seen this before).
'amber' with letters rearranged gives 'embar'.
'embar'+'goes'='EMBARGOES'
(Other definitions for embargoes that I've seen before include "Stops" , "Trade barriers" , "Bans" .)
