Tag reinstated wrongly in commercial area (7,6)

I believe the answer is:
trading estate
'commercial area' is the definition.
The definition suggests a singular noun which matches the answer.
'tag reinstated wrongly' is the wordplay.
'wrongly' indicates anagramming the letters.
'tag'+'reinstated'='tagreinstated'
'tagreinstated' with letters rearranged gives 'TRADING ESTATE'.
'in' is the link.
Can you help me to learn more?
(Other definitions for trading estate that I've seen before include "industrial park" , "Commercial zone" , "Industrial business area" , "Area with factories" , "Industrial/commercial zone" .)
