Put off when importing tin bottle (8)
I believe the answer is:
decanter
'bottle' is the definition.
(I know that decanter is a type of bottle)
'put off when importing tin' is the wordplay.
'put off' becomes 'deter' (both can mean to discourage).
'when importing' is an insertion indicator.
'tin' becomes 'can' (synonyms).
'deter' going around 'can' is 'DECANTER'.
(Other definitions for decanter that I've seen before include "source of drink" , "quantity of wine?" , "Type of carafe" , "Glass container for table wine" , "Glass spirits container" .)
