Tea-producing region of India (5)
I believe the answer is:
assam
'tea-producing region of india' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for assam that I've seen before include "Kind of Indian tea" , "Variety of tea" , "North-east Indian tea state" , "Type of tea" , "Asian area?" .)
